The prevalence of anxiety symptoms and disorders among ophthalmic disease patients.

Background:Progressive and irreversible vision loss has been shown to place a patient at risk of mental health problems such as anxiety. However, the reported prevalence of anxiety symptoms and disorders among eye disease patients vary across studies. Thus, this study aims to clarify the estimated prevalence of anxiety symptoms and disorders among ophthalmic disease patients.Methods:Relevant studies on the prevalence of anxiety symptoms and disorders among eye disease patients were collected through international databases, PubMed, Scopus, and Web of Science. A random-effects model was used to determine the pooled prevalence of anxiety symptoms and disorders among ophthalmic disease patients.Results:The 95 included studies yielded a pooled prevalence of 31.2% patients with anxiety symptoms and 19.0% with anxiety disorders among subjects with ophthalmic disease. Pediatric patients were more anxious (58.6%) than adults (29%). Anxiety symptoms were most prevalent in uveitis (53.5%), followed by dry eye disease (DED, 37.2%), retinitis pigmentosa (RP, 36.5%), diabetic retinopathy (DR, 31.3%), glaucoma (30.7%), myopia (24.7%), age-related macular degeneration (AMD, 21.6%), and cataract (21.2%) patients. Anxiety disorders were most prevalent in thyroid eye disease (TED, 28.9%), followed by glaucoma (22.2%) and DED (11.4%). When compared with healthy controls, there was a twofold increase on the prevalence of anxiety symptoms (OR = 1.912, 95% CI 1.463–2.5, p < 0.001) and anxiety disorders (OR = 2.281, 95% CI 1.168–4.454, p = 0.016).Conclusion:Anxiety symptoms and disorders are common problems associated with ophthalmic disease patients. Thus, comprehensive and appropriate treatments are necessary for treating anxiety symptoms and disorders among ophthalmic disease patients.

Background:The prevalence of depression among different eye disease patients varies across studies and has not been systematically reviewed. Previous studies report a wide range of prevalence of depressive symptoms varying between 18-89% in the population. This study is to provide a summary of the prevalence of depression among patients with cataract.Aim:To assess prevalence of depressive symptoms in patients having visual impairment due to cataract.Methods:164 consecutive patients with cataract were selected from the Ophthalmology Department in a tertiary care hospital. Depressive symptoms were assessed using the Brief Patient Health Questionnaire and severity was assessed using the Hamilton Depression Rating Scale.Result:Prevalence of depression was 24% among patients with senile cataract. In the final multiple logistic regression analysis, age, gender, place of residence, education and household income were found to be significantly associated with depression.Conclusion:The prevalence of depressive symptoms is common among patients with cataract.

Orbital decompression for thyroid eye disease: surgical treatment outcomes in endocrinological assessment.

Surgical orbital decompression involves removal of one or more of the orbital bony walls in order to gain space for overgrown muscles and adipose tissue, which results in a reduction in pressure on the eye. This observational study aims to perform an endocrinological assessment of the surgical treatment outcomes of thyroid eye disease (TED) patients before and after orbital decompression. This retrospective study included 51 TED patients (84 orbits) who underwent endoscopic orbital decompression (EOD) or balanced orbital decompression. The effect of surgical treatment was evaluated via the clinical activity score (CAS), and modified NOSPECS and EUGOGO classification. Before orbital decompression, the average CAS index was 3.83 ± 1.86 points, whereas the modified NOSPECS score was 3.31 ± 0.97 points. After surgical intervention, the values were as follows: 2.07 ± 1.84 points for CAS and 2.5 ± 0.97 points for modified NOSPECS. The EUGOGO classification before surgery showed that Graves' orbitopathy (GO) was mild, moderate to severe, and sight-threatening in 1%, 25%, and 74% of the orbits, respectively. After surgery, GO was determined to be mild, moderate to severe, and sight-threatening in 24%, 57%, and 19% of the orbits, respectively. Statistical analysis was performed using the R 3.6.2 statistical environment. Inference about the statistical reliability of the parameter was made by calculating the mean and the 95% credibility interval (CI). The severity of TED decreased after orbital decompression. The CAS, and modified NOSPECS and EUGOGO classification showed a statistically reliable postoperative reduction. The drop in activity of the disease after orbital surgery requires careful follow-up.

Prevalence of Depression in Patients with Visual Impairment in Cataract: A Systematic Literature Review

Introduction. Depression is a chronic and often recurrent psychiatric disorder among older people, and its association with cataracts has not been well defined. Several studies have shown that depression is a prevalent mental health problem in ophthalmological practice and is often unrecognized or untreated. A systematic review was conducted to investigate the prevalence of depression in patients with visual impairment in cataracts.Methods. A literature search was performed on PubMed and Medline in the last 10 years (2011 to 2021). The search strategy used the following terms: (prevalence) and (visual impairment or blindness) and (cataract) and (depression or depressive symptoms). Of the 544 electronics, 226 articles were selected in free full text and 10 studies were identified as being possibly relevant. Results. Depression was associated with visual impairment in all studies. The prevalence of depression is higher in patients with eye disease.Conclusion. The prevalence of depression among eye disease patients was higher than that in healthy people. Cataract surgery is associated with an improvement in depressive symptomatology. More research is needed to identify effective strategies for the prevention and management of depression in patients with cataracts or visual impairment.

Efficacy of Topical Hydrocortisone in Combination with Topical Ciclosporin A for the Treatment of Dry Eye Disease in Patients with Sjögren Syndrome.

Introduction The aim of this randomized, observer-masked, parallel group study was to evaluate the short-term and long-term effects of topical hydrocortisone administered in addition to topical ciclosporin A for the first 2 weeks of the treatment in patients with dry eye disease associated with Sjögren syndrome. Materials and Methods 24 eyes of 12 patients with severe dry eye disease associated with Sjögren syndrome were included in this study. Both eyes of all patients were treated with preservative-free Ciclosporin A eye drops once daily for 6 months. Additionally, one eye of each patient received hydrocortisone eye drops three times daily for the first two weeks of treatment. The study parameters were assessed before treatment, after 2 weeks, and after 6 months of treatment. Results Tear BUT and corneal fluorescein Oxford staining grade showed significant differences with respect to the baseline when treated with ciclosporin A and hydrocortisone (CsA + Hc) and a nonsignificant increase when treated with ciclosporin A (CsA) alone. After 6 months of treatment, significant increases of tear BUT and corneal Fluorescein Oxford staining grade compared to baseline could be observed in both treatment groups. Aberrometry measurements showed significantly increased optical image quality after 6 months in the CsA + Hc group, while no significant changes could be detected in the eyes treated with CsA alone. However, no significant differences between the two treatment groups could be detected. Discussion. This study indicates that hydrocortisone combined with ciclosporin A therapy may provide fast improvement of clinical symptoms and could have long-term positive effects on the optical image quality in severe DED patients with Sjögren syndrome.

Tear osmolarity, dry eye syndrome, blepharospasm and botulinum neurotoxin

To assess the severity of dry eye disease in patients with blepharospasm (BEB) before (control) and after injection of botulinum neurotoxin A (BoNT/A). Cross-sectional study. Patients with clinically diagnosed BEB and no known history of dry eye syndrome prior to the onset of the disease, before (controls) or after injection with one of the three available types of BoNT/A: onabotulinumtoxinA (Botox®; Allergan, Irvine, CA, USA), abobotulinumtoxinA (Dysport®; Beaufour Ipsen Pharma SAS, Paris, France) or incobotulinumtoxinA (Xeomin®; Merz Pharma GmbH, Frankfurt, Germany) every 3 months. Tear osmolarity and Schirmer's I-test were measured at the first visit for non-treated BEB patients as controls and 3 months after BoNT/A injection. The study consisted of 101 BEB patients (86 females, 15 males) with a mean age of 67 years (range 30-86 years). Seventeen patients were untreated, 26 treated with onabotulinumtoxinA, 23 treated with abobotulinumtoxinA and 35 treated with incobotulinumtoxinA. Post-injection mean tear osmolarity was not significantly higher among patients treated with onabotulinumtoxinA, abobotulinumtoxinA, or incobotulinumtoxinA (P=0.65, P=0.92, and P=0.15, respectively), compared to controls, remaining less than 308 mosm/mL. Mean Schirmer's I-test results remained under 5mm and did not vary between the four groups. The results clearly demonstrate that reduced tear secretion appears to be present in BEB patients even prior to treatment. This decreased lacrimal secretion was not correlated with hyperosmolarity. Clinicians should proactively treat dry eye syndrome in conjunction with management of the blepharospasm.

Risk of physical injuries in children and teens with ophthalmic diagnoses in the OptumLabs Data Warehouse

To evaluate how eye diseases affect the risk of injuries (fractures, musculoskeletal, head and eye injuries) in children and teens. Claims from the OptumLabs Data Warehouse, a longitudinal deidentified commercial insurance claims database, were analyzed. Eligible subjects were aged <19years at the time of their eye disease diagnosis, enrolled in the health plan between 2007 and 2018, and had >1 visit for >1 significant eye disease (strabismus, amblyopia, nystagmus, structural diseases), based on ICD9/10 codes. Controls were children in the same database who had no eye disease codes reported. Demographics and injury claims (fractures, musculoskeletal injuries, head injuries and eye injuries) were compared. The overall incidence of any subsequent physical injury (even into adulthood) was 29% in eye disease patients and 23% in controls (P<0.001). After accounting for covariates, the hazard ratio for injury with any type of eye disease was 1.14 (95% CI, 1.13-1.15), 1.17 (95% CI, 1.16-1.18), 0.97 (95% CI, 0.96-0.98), and 1.63 (95% CI, 1.60-1.66) for musculoskeletal injuries, fractures, head injuries, and eye injuries, respectively. The eye disease with the highest adjusted injury risk was nystagmus (HR=1.26; 95% CI, 1.23-1.28), followed by optic neuritis and pseudotumor cerebri (HR=1.25). The eye diseases with the lowest risk included amblyopia, esotropia, and glaucoma (HR≤1.06). There was an increased long-term risk of physical injury among children and teens with eye disease. The clinical significance of these small differences is unclear.

Corneal Nerve Abnormalities in Painful Dry Eye Disease Patients.

Background: This study aimed to compare the corneal nerve structural abnormalities detected using in vivo confocal microscopy (IVCM) in patients with neuropathic corneal pain (NCP) secondary to primary meibomian gland dysfunction (MGD) or autoimmune dry eye (AIDE). Methods: A two-stage retrospective nested case–control study was conducted. First, data from patients with either MGD or AIDE were assessed, selecting only cases with no corneal pain (VAS = 0) or severe pain (VAS ≥ 8). Ocular signs and symptoms of the 238 selected patients were compared between painful and painless cases. Next, painful patients with no corneal damage (Oxford score ≤ 1) were selected within each study group, defining the cases with NCP (i.e., “pain without stain”). IVCM images from all groups were compared with prospectively-recruited healthy controls, focusing on dendritiform cell density and nerve abnormalities (density, tortuosity, microneuromas). Results: AIDE patients had more ocular signs/symptoms than MGD patients. Compared with healthy controls, AIDE-related NCP patients showed increased nerve tortuosity and number of neuromas, whereas MGD-related NCP patients had reduced nerve density and increased number, perimeter, and area of microneuromas. Microneuromas were also observed in healthy controls. Furthermore, a higher number of microneuromas was found in MGD-related NCP compared to AIDE-related NCP or painless MGD. Conclusions: MGD-related NCP was associated with significantly more corneal nerve abnormalities than AIDE-related NCP or healthy controls. Although IVCM can be useful to detect NCP-related corneal nerve changes in such patients, the diagnosis of dry eye disease-related NCP will require an association of several IVCM-based criteria without relying solely on the presence of microneuromas.

Repeatability and Reproducibility of SMTube Measurement in Dry Eye Disease Patients

Purpose To evaluate the intraobserver repeatability and interobserver reproducibility of Strip Meniscometry Tube (SMTube) and determine the correlations among the SMTube measurements and other ocular examinations in dry eye disease (DED) patients. Methods The study recruited 73 eyes of 49 DED patients. Every subject was subjected to the following five measurements sequentially: the Ocular Surface Disease Index (OSDI) questionnaire, Tear Meniscus Height (TMH) assessment, SMTube measurements, tear film breakup time (BUT) examination, and Schirmer I test (SIT). The repeatability and reproducibility of the measurements were assessed by the intraclass correlation coefficient (ICC) and the Bland–Altman analysis, and the correlations were evaluated by the Spearman rank-order correlation. Results The repeatability and reproducibility of the SMTube measurements were good in DED patients. The ICCs between the repeatability and reproducibility of the SMTube measurements were 0.789 and 0.741, respectively, and the Bland–Altman 95% limits of the repeatability and the reproducibility were −1.726 to 1.658 and −0.967 to 1.474, respectively (all P < 0.01). The SMTube measurements had correlations with TMH, BUT, and SIT. The Spearman rank correlation coefficients between SMTube and TMH; SMTube and Schirmer I test; and SMTube and BUT were 0.632, 0.617, and 0.653, respectively (all P < 0.01). Conclusions The measurements of the SMTube may provide a novel, swift, noninvasive, and convenient approach to screen and diagnose DED with acceptable repeatability and reproducibility and specific correlations with TMH, BUT, and SIT.

The Relationship Between Dry Eye in Adults with Indications for Kidney Transplantation and Influence Factors.

PurposePatients with end-stage renal failure are susceptible to dry eye disease. This study explores the relationship between dry eye disease and influence factors.Patients and MethodsThe control group consisted of 57 healthy subjects who were kidney donors. They were of the same age and sex as the kidney transplant recipients. The outcome variable was the dry eye condition of the participants. The Schirmer test confirmed dry eye disease, TBUT (breakup time test), and the Eye Surface Disease Index (OSDI) questionnaire, using linear regression to evaluate the association.ResultsThe total number of subjects was 146 (89 kidney recipients and 57 kidney donors). When univariate analysis found the level of visual acuity, the age group involved was statistically significant, while the other factors were not statistically significant. In multivariable logistic regression analysis, age (odds ratio: 2.8, p<0.05), smoking history (odd ratio: 0.1, p<0.05), corneal conjunctival calcification (odd ratio: 0.2, p<0.05); central corneal thickness (odd ratio: 1.02, p<0.05) is considered to be an influence factor for disease progression.ConclusionAge group, smoking history, corneal central thickness, and conjunctival calcification are factors for dry eye disease in patients preparing to receive a kidney. These results reinforce the evidence for multifactorial dry eye disease in patients with renal impairment.

Is there a role for tapered topical dose steroidal treatment for dry eye disease? A randomized, pilot study.

To evaluate the effect of tapered doses of loteprednol-etabonate in dry eye disease patients. Dry eye and treatment outcomes were assessed by Schirmer I test, tear BUT, lissamine green conjunctival staining, fluorescein corneal staining, and HLA-DR expression on conjunctival cells. Patients received either loteprednol-etabonate 0.5% twice daily for 14 days tapered to once daily for 14 days, and then twice weekly for 28 days (n = 10), or NaCl 0.9%. A significant decrease of ocular surface inflammation and improvement of symptoms was recorded in the study group compared with controls at days 14 and 56. Change from baseline in HLA-DR expression in CD45+ conjunctival cells was significantly higher in treated patients at day 14. Intraocular pressure and best corrected visual acuity were preserved in all treated eyes. Tapered doses of loteprednol etabonate 0.5% suspension controlled ocular surface inflammation, improving dry eye symptoms.

Differential expression of tear film cytokines in Stevens\u2013Johnson syndrome patients and comparative review of literature

To investigate the differential expression of tear cytokine levels among chronic Stevens–Johnson syndrome (SJS) patients to better understand the role of significantly altered cytokines in disease development. Tear samples were collected using Schirmer strips in 24 eyes of chronic SJS, 24 eyes of age and gender-matched controls, and 14 eyes of aqueous deficiency dry eye disease (DED) patients. The cytokine analysis was performed among 18 analytes which include pro-inflammatory, anti-inflammatory factors, and ELR-negative CXC chemokines. String analysis was performed for the significantly altered cytokines to understand their co-expression and role in the disease development. Additionally, a literature review was conducted to identify the signature cytokines present in chronic SJS tears. The differential expression of IL-6 (p ≤ 0.029), CXCL8/IL-8 (p ≤ 0.009), IL-1β (p ≤ 0.041), IL-2 (p ≤ 0.025), IL-10 (p ≤ 0.053), and CXCL-10 (p ≤ 0.044) were observed in chronic SJS patients and healthy controls. Whereas, IL-6 (p ≤ 0.029), CXCL8/IL-8 (p ≤ 0.058), CCL4 (p ≤ 0.056), GM-CSF (p ≤ 0.0001) IL-10 (p ≤ 0.025), and CXCL-10 (p ≤ 0.010), were differentially expressed in SJS as compared to severe DED patients. String analysis of the significantly altered cytokines revealed the involvement of several biological processes including the chronic inflammatory response, nitric oxide synthesis, angiogenesis, and cellular response to drugs. Among all the cytokines evaluated, the expression of CXCL8/IL-8 and CXCL10 levels were consistently reported in the literature. There was a differential expression of tear cytokines in SJS when compared to DED and healthy controls. The differential expression of CXCL8/IL-8 and CXCL10 was in line with existing literature and their role in chronic SJS pathogenesis merits further evaluation.

Ocular Surface Microbiota in Diabetic Patients With Dry Eye Disease.

PurposeTo investigate the ocular surface (OS) commensal bacteria profiles of patients with diabetes mellitus (DM) and dry eye disease (DED).MethodsIn the present study, subjects were assigned to four groups: 37 to the diabetic mellitus with dry eye disease (DM with DED) group, 22 to the diabetes mellitus (DM)-only group, 34 to the dry eye disease (DED)-only group, and 22 to the control group. Tear fluid was collected using Schirmer's tear secretion test paper. 16S ribosomal ribonucleic acid (rRNA) gene sequencing was used to analyze the bacterial microbiota.ResultsThe DM with DED group showed the highest operational taxonomic unit (OTU) numbers and alpha diversity and the most different beta diversity. The groups shared the four most abundant phyla, accounting for over 96% of the total abundance. At the genus level, there were 10 types of overlap in the core microbiota in the groups. They showed significant differences between the groups. Additionally, the DM with DED group and the control group showed four unique core genera, respectively. Unclassified Clostridiales and Lactobacillus were the core microbiota members of the DM with DED group, the DM-only group, and the DED-only group, but not the control group.ConclusionsIn the present study, our results showed that the patients in the DM with DED group had a more complex and comprehensive ocular surface microbial composition. To the best of our knowledge, this is the first study to reveal the microbial profile of dry eye disease in patients with diabetes mellitus.

Tear dynamics testing and quantitative proteomics analysis in patients with chronic renal failure

Ocular surface changes may develop in patients with chronic renal failure (CRF) undergoing hemodialysis. In recent years, an association of CRF with dry eye syndrome has been emphasized. However, tear proteomics of CRF patients has not been analyzed. Here, we performed systematic profiling of the tear film proteins in CRF patients through use of isobaric tags for relative and absolute quantitative (iTRAQ) MS/MS, aiming to identify associations between dry eye symptoms and expression of tear proteomic changes in patients with CRF undergoing hemodialysis. Twenty CRF patients and ten healthy subjects underwent a series of ophthalmic examinations. Tear samples from the participants were analyzed by iTRAQ approach. A total of 1139 tear proteins were screened, and 212 differentially expressed proteins were identified. The pattern changes included 77 whose expression levels were upregulated (fold increase >1.2) whereas 135 others that were downregulated (fold decrease <1/1.2). Bioinformatics analysis showed that these proteins were significantly enriched in lipid metabolism, inflammatory, and immune response pathways. Furthermore, APOA1, APOA4, APOB, APOE, S100A8, S100A9, S100A4, HSP90B and other molecules were significantly changed. Our study elucidated the characteristics of tear dynamics and protein markers in CRF patients undergoing hemodialysis.Significance: Despite the association of chronic renal failure (CRF) with dry eye disease, there are no reports describing potentially important differentially expressed tear proteins in CRF patients undergoing hemodialysis. It is still a challenge to obtain a comprehensive description of the pathogenesis of dry eye in CRF patients which hinders establishing a patient specific therapeutic scheme. Our study is the first iTRAQ proteomics analysis of the tears of patients with CRF, which reveals the changes in the protein expression profile in CRF patients afflicted with dry eye disease. The identity was verified of some relevant differentially expressed proteins, and they may be candidate diagnostic markers of dry eye disease in patients with CRF. These tear film protein constituents found in hemodialysis patients can be of important clinical significance in treating this condition.

Changes in anterior segment parameters and presence of dry eye disease in patients with acromegaly: A Sirius topography study combined with meibography

PurposeTo investigate anterior segment parameters (ASPs) and dry eye disease (DED), including the status of the meibomian glands, in patients with acromegaly. MethodsIn this cross-sectional, comparative study, 36 acromegaly patients and 40 healthy sex- and age-matched controls were included. Participants received a comprehensive ophthalmological examination, including intraocular pressure measurements with Goldmann applanation tonometry (IOPGAT) and central corneal thickness corrected intraocular pressure (IOPCCT) measurements, and were evaluated for ASPs and DED. For ASPs, white-to-white (WTW), apical (ACT) and thinnest corneal thickness (TCT), corneal volume (CV), keratometry readings (K1, K2, and Kmean), anterior chamber depth (ACD) and volume (ACV), and iridocorneal angle (ICA) were obtained via Sirius topography. DED was assessed with Schirmer's test, tear breakup time (TBUT), and Ocular Surface Disease Index (OSDI) scores. Meibography scores (MSs) were obtained with the Sirius topography device. ResultsPatients had higher mean IOPGAT (P = .006), IOPCCT (P = .01), ACT (P = .024), and TCT (P = .005) but narrower ICA (P = .014) than controls. Although Schirmer's test did not differ between the groups (P = .442), patients had higher OSDI (P < .001), higher MS (P = .001), and shorter TBUT (P = .002). ConclusionPatients with acromegaly have greater IOP, greater corneal thickness, but narrower ICA than healthy individuals, as well as DED with increased MSs, which suggests meibomian gland dysfunction.

Correction of lower eyelid retraction combined with entropion in thyroid eye disease patients of East Asian ancestry.

This study evaluates causes and treatment of lower eyelid retraction with co-existing entropion in Thyroid Eye Disease (TED) patients of East Asian ancestry. The medical records for 25 eyelids from 15 TED patients with lower eyelid retraction and entropion who had undergone combined orbital decompression and lower eyelid retraction correction surgery at the Second Hospital of Dalian Medical University from January 2017 to December 2018 were prospectively reviewed. We build a numerical model of biomechanics to analyze von Mises stress and displacement at the lower eyelid. The mean follow-up duration was 6 ± 2 months. The difference of mean exophthalmos was 5.16 ± 1.21 mm (t = 21.26, p = 4.479E-17 < 0.05). The difference of mean MRD2 was 1.9 ± 0.14 mm (t = 67.57, p = 6.751E-29 < 0.05). About 2 of 25 eyelids entropion recurred postoperatively; the overall success rate was 92%. The biomechanical analysis results reveal that the eyelid margin is given more stress and caused more displacement in East Asian ancestry under the same force of pressure. This study shows that the lower eyelid retraction with coexistent entropion is attributable to the unique anatomical features of patients of East Asians ancestry. We corrected the lower eyelid retraction and entropion during the orbital decompression operation. The results show that this method is safe and effective. It can simultaneously improve the symptoms of TED patients such as exophthalmos, lower eyelid retraction, and entropion, with minimal complications.

Aesthetic Eyelid Measurements of "Beautiful People": Gender Differences and Application for Thyroid Eye Disease Patients.

Background:There remains a paucity of studies investigating measurements of periocular structures of people popularly seen as “beautiful.” Such measurements may be helpful in establishing postoperative goals and measuring aesthetic outcomes. This study (1) identifies aesthetic measurements of the periocular structures in idealized celebrities, (2) determines gender differences in such measurements, and (3) compares these measurements to patients who underwent surgical repair of upper eyelid retraction associated with thyroid eye disease.Methods:Digital analysis of 38 celebrity photographs in People’s “Most Beautiful People” and “Sexiest Man Alive” was performed to measure image-derived (denoted with an “i”) margin reflex distance (iMRD1), tarsal platform show (iTPS), brow fat span (iBFS), and iTPS:iBFS ratio. The same analysis was used for 35 women who underwent surgical repair for thyroid eye disease-related upper eyelid retraction.Results:Significant gender differences (P < 0.05) were observed in celebrity metrics, with women having higher upper eyelids (longer iMRD1) (3.30 mm versus 2.50 mm), longer iTPS measurements (3.90 mm versus 2.50 mm), and larger iTPS:iBFS values (0.31 versus 0.20). Postoperative thyroid eye disease patients had significantly higher upper eyelids (longer iMRD1s) (4.80 mm versus 3.30 mm), longer iTPS (5.10 mm versus 3.90 mm), and larger iTPS:iBFS (0.37 versus 0.31) than celebrities.Conclusions:There are significant gender differences in the periocular metrics of “beautiful people.” Optimal aesthetic outcomes may be more effectively obtained by achieving a preferred range of ratios than by relying on independent measurements. Although aesthetic outcomes are multi-factorial, measurements of “beautiful” people provide helpful guidelines to gauge aesthetic outcomes.

Reliability of Chinese web-based ocular surface disease index questionnaire in dry eye patients: a randomized, crossover study.

To assess the reliability of web-based version of ocular surface disease index in Chinese (C-OSDI) on clinically diagnosed dry eye disease (DE) patients. A total of 254 Chinese participants (51% male, 129/254; mean age: 27.90±9.06y) with DED completed paper- and web-based versions of C-OSDI questionnaires in a randomized crossover design. Ophthalmology examination and DED diagnosis were performed prior to the participants being invited to join the study. Participants were randomly designated to either group A (paper-based first and web-based second) or group B (web-based first and paper-based second). Final data analysis included participants that had successfully completed both versions of the C-OSDI. Demographic characteristics, test-retest reliability, and agreement of individual items, subscales, and total score were evaluated with intraclass correlation coefficients (ICC), Spearman rank correlation, Wilcoxon test and Rasch analysis. Reliability indexes were adequate, Pearson correlation was greater than 0.8 and ICCs range was 0.827 to 0.982; total C-OSDI score was not statistically different between the two versions. The values of mean-squares fit statistics were very low compared to 1, indicating that the responses to the items by the model had a high degree of predictability. While comparing the favorability 72% (182/254) of the participants preferred web-based assessment. Web-based C-OSDI is reliable in assessing DED and correlation with the paper-based version is significant in all subscales and overall total score. Web-based C-OSDI can be administered to assess individuals with DED as participants predominantly favored online assessment.

Ocular Surface Changes in Patients with Thyroid Eye Disease: An Observational Clinical Study.

BackgroundThis study aimed to compare ocular surface parameter changes in active and inactive thyroid eye disease (TED) patients and controls.MethodsThis is an observational clinical study that included 60 eyes divided into three groups following clinical activity score (CAS) assessment. The first group (Group A) comprised 20 eyes with active TED (CAS score ≥3/7), while the second group (Group B) comprised 20 eyes with inactive TED (CAS score <3/7) and the third group (Group C) comprised 20 eyes of controls without dry eye manifestations. The palpebral fissure height, degree of proptosis, degree of lagophthalmos, ocular surface disease index (OSDI), Schirmer test without anesthesia, corneal fluorescein staining (CFS), non-invasive tear break-up time (NITBUT), tear meniscus height (TMH), lipid layer thickness (LLT), meiboscore, meibomian gland dysfunction (MGD), and thyroid antibodies were assessed and data were compared between study participants.ResultsThe mean OSDI was 40.0 ±5.80 in Group A, which significantly differed from Group B with a mean of 26.5 ±5.10 (p=0.02). There were significant differences between the two groups regarding palpebral fissure height (p=0.02), amount of proptosis (p=0.008), and degree of lagophthalmos (p=0.001). Similarly, active TED patients had more decreased tear secretion than inactive TED patients (p=0.012). Moreover, active TED patients showed a significant increase in Meibomian gland loss areas in both upper and lower eyelids compared with inactive TED patients (p=0.001). Corneal fluorescein staining also revealed a statistically significant difference between the studied groups (p=0.0001).ConclusionThis study showed differences regarding ocular surface parameter changes between both active and inactive TED and compared to controls. Further studies are needed to confirm these results.

Corneal nerve structure in patients with primary Sj\xf6gren\u2019s syndrome in China

BackgroundThe aim of this study was to evaluate the in vivo confocal microscopic morphology of corneal subbasal nerves and its relationship with clinical parameters in patients with primary Sjögren’s syndrome in China.MethodsThis was a case control study of 22 dry eye disease (DED) patients with primary Sjögren’s syndrome (pSS) and 20 control subjects with non-Sjögren dry eye disease (NSDE). Each patient underwent an evaluation of ocular surface disease using the tear film break-up time (TBUT), noninvasive tear film break-up time (NIKBUT), noninvasive tear meniscus height (NIKTMH), corneal staining (National Eye Institute scale, NEI), Schirmer I test, meibography, and corneal subbasal nerve analysis with in vivo confocal microscopy (IVCM). The right eye of each subject was included in this study.ResultsSS patients showed a shorter TBUT (P = 0.009) and Schirmer I test results (P = 0.028) than the NSDE group. However, there was no significant difference in NIKBUT between the two groups (P = 0.393). The nerve density of subbasal nerves, number of nerves and tortuosity of the SS group were significantly lower than those of the NSDE group (P = 0.001, P < 0.001 and P = 0.039, respectively). In the SS group, the mean nerve length was correlated with age and the Schirmer I test (r = − 0.519, P = 0.013 and r = 0.463, P = 0.035, respectively). Corneal staining was correlated with nerve density and the number of nerves (r = − 0.534, P = 0.013 and r = − 0.487, P = 0.025, respectively).ConclusionsSjögren syndrome dry eye (SSDE) patients have more severe clinical dry eye parameters than non-Sjögren dry eye disease (NSDE) patients. Compared with NSDE patients, we found that SSDE patients showed decreased corneal subbasal nerve density and numbers.
