Association Between Acquired Punctal Stenosis and Ocular Surface Disease: the Egg and the Chicken Story

ABSTRACT Purpose This study explores the relationship between acquired punctal stenosis (PS) and ocular surface disease (OSD), assessing causal mechanisms and clinical impacts, utilizing a combination of a comprehensive literature review and a detailed analysis of a patient cohort from a tertiary care center. Methods Data from 213 PS patients at Sheba Medical Center were retrospectively analyzed, evaluating various OSD symptoms and treatment effectiveness through standardized clinical assessments and statistical tests. Results Predominantly older and female, many patients exhibited bilateral PS. OSD symptoms were found in 35.2% of all patients. Treatments like punctoplasty with stents significantly alleviated symptoms. Significant associations between treatment modalities and symptom improvement were identified. Conclusions PS and OSD have acomplex, bidirectional relationship that complicates treatment outcomes. This study underscores the need for thorough diagnostic approaches and personalized treatments to improve PS management. Further research is essential to deepen understanding of PS-OSD interactions and develop effective therapies.

Recombinant Deoxyribonuclease I Eye Drops for Ocular Graft Versus Host Disease: Results of a Randomized Clinical Trial.

We have previously shown that neutrophil extracellular traps (NETs) are present on the ocular surface of patients with ocular graft versus host disease (oGVHD), contributing to inflammation and surface disease. Therefore, we performed a clinical trial using deoxyribonuclease I (DNAase) eye drops to test the hypothesis that reducing the abundance of NETs from the ocular surface will reduce signs and symptoms of oGVHD. A prospective, phase I or II, randomized, placebo-controlled, double-masked clinical trial was performed to determine the safety and preliminary efficacy of DNAase (0.1%) eye drops four times daily for 8 weeks in patients with oGVHD (n=58). Intent-to-treat analysis was performed to determine the change in safety outcome measures (drug tolerability and proportion of adverse events) and efficacy outcome measures (ocular surface disease index [OSDI] score and corneal staining) between baseline and week 8. Tolerability and adverse events were similar in the vehicle and DNAase groups. Within the DNAase group (but not the vehicle group), corneal staining showed a statistically significant and clinically meaningful reduction at week 8 (3.50 [2.75; 5.00]) compared with baseline (5.00 [3.00; 7.00]). The OSDI score also showed a statistically significant clinically meaningful reduction of 18.4 (9.16; 33.1) ( P <0.001) at week 8 compared with baseline (45.5 [31.8; 50.0]) within the DNAase group. The proportion of eyes that had improvement in subjective global assessment (SGA) and mucous discharge was significantly greater in the DNAase group (55.6% and 57.7% at weeks 4 and 8, respectively; P <0.0001 at both time points) as compared with the vehicle group (35.7% and 34.0% at weeks 4 and 8, respectively). Treatment of patients with oGVHD using DNAase eye drops is safe and demonstrates preliminary efficacy. Deoxyribonuclease I eye drops can potentially reduce the severity of signs and symptoms of ocular surface disease in patients with oGVHD.

Understanding Ocular Surface Disease in Glaucoma: A Comparative Analysis of Symptoms and Objective Parameters.

Background Glaucoma is a progressive optic neuropathy that may result in irreversible visual impairment and can diminish quality of life. Lowering intraocular pressure (IOP) through topical eyedrops is usually the primary approach to managing glaucoma. However, long-term treatment poses a risk to ocular surface health, leading to ocular surface disease (OSD). Preservative-containing eyedrops are implicated in OSD development due to their detrimental effects on the tear film and goblet cell density. OSD symptoms may impact patient compliance due to local side effects. This study aims to assess OSD in glaucoma patients receiving topical treatment, quantify symptoms and objective ocular surface parameters, and compare them to a control group not using topical glaucoma medications. Methodology Patients diagnosed with primary open-angle glaucoma receiving topical treatment and a control group were included in this study. To assess OSD, patients completed the Ocular Surface Disease Index (OSDI) questionnaire to evaluate symptoms and underwent objective measurements of ocular surface parameters using a keratograph. These parameters included assessments of bulbar redness and non-invasive keratograph tear break-up time (NIKTBUT). Results A cohort of 92 patients was subjected to examination, comprising 66 individuals diagnosed with glaucoma and 26 controls. Within the glaucoma patient subset, the mean number of IOP-lowering drugs administered was 2.42 ± 0.18, with 22.7% exclusively utilizing preservative-free eye drops. Our investigations unveiled a substantial prevalence of OSD symptoms, manifesting not only within the glaucoma cohort but also among the control group, with 72.7% and 53.8%, respectively (p = 0.224), reporting moderate-to-severe symptoms (OSDI > 23). Remarkably, OSDI scores exhibited higher values among female participants (p = 0.039) and glaucoma patients using prostaglandins (p<0.001) and were negatively correlated to the number of IOP-lowering drugs used (-0.448; p < 0.001). Furthermore, employing keratograph assessment, we discerned heightened bulbar redness (1.86 ± 0.07) in the glaucoma group compared to the control group (1.58 ± 0.07; p = 0.008). Glaucoma subgroup analyses further unveiled higher bulbar redness among glaucoma patients employing carbonic anhydrase inhibitors (p = 0.035) and applying medication preservatives (p = 0.045) but lower among individuals using beta-blockers (p = 0.018). However, the NIKTBUT did not show significant variance between the two groups (glaucoma group: 10.19 ± 0.85 seconds; control group: 10.96 ± 1.37 seconds; p = 0.499). Conclusions Our study revealed a significant prevalence of OSD in our sample, with the OSDI questionnaire showing limited specificity. The notable increase in bulbar redness pointed to an elevated prevalence of OSD among glaucoma patients, emphasizing the considerable impact of preservatives on ocular surface damage. Recognizing the potential damage to the tear film and ocular surface is crucial for glaucoma experts, who must employ comprehensive therapeutic strategies to mitigate symptoms, advocating for the preferential use of preservative-free medications, when possible, for optimizing long-term treatment.

Higher occurrence of ocular surface disease symptoms in patients with atopic dermatitis—Data in the FOREVER study

Aims/Purpose: Atopic Dermatitis (AD) is a common inflammatory skin disease that often begins in early childhood and may continue into adulthood. AD severity, and comorbid bronchial asthma and rhinitis have been associated with increased prevalence of Ocular Surface Diseases (OSD) in AD patients (1). OSD is common in the general population and symptoms from the ocular surface do not always lead to examination and diagnosis by healthcare professionals. The purpose of this study was to investigate the occurrence of self‐reported symptoms from the ocular surface in AD patients compared to the population without AD.Methods: A questionnaire study was conducted as a part of project FOREVER (Finding Ophthalmic Risk and Evaluating the Value of Eye exams and their predictive Reliability) to examine the relationship between eye and overall health in Danish citizens. Symptoms related to the ocular surface included tearing, blurred vision, red, itching, burning, gritty, and dry eyes. Logistic regression models were used to investigate associations between AD and the occurrence of symptoms related to the ocular surface.Results: 36874 people had completed the FOREVER questionnaire. 797, 3305 and 32 772 participants answered that they have current AD, previously had AD, and never had AD, respectively. 69% (550/797) and 67% (2201/3305) in the group with current AD and previous AD experienced one or more ocular surface symptoms compared to 60% (19 517/32 772) in the non‐AD group. The odds ratio of AD and ocular surface symptoms was 1.27 [1.09–1.48] (p &lt; 0.01) and 1.17 [1.08–1.26] (p &lt; 0.001) for current and previous AD when adjusting for age, sex, smoking status, and atopic comorbidities; bronchial asthma and rhinitis.Conclusions: Our study found that participants with AD from the FOREVER cohort reported a higher occurrence of OSD symptoms compared to participants who have never suffered from AD. This suggest that AD patients are at higher risk of developing OSD symptoms.Reference1. Rønnstad ATM, Hansen PM, Halling AS, et al.

Isotretinoin-Related Eye Dryness in Acne Patients in Qassim, Saudi Arabia.

Background Isotretinoin is a commonly prescribed agent mainly used to treat acne vulgaris. Since its Food and Drug Administration (FDA) approval, the subject of its associations with various medical conditions has become a growing interest in many investigational studies. Methodology A retrospective study was conducted using the validated Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaire. All statistical calculations were performed using the Statistical Package for the Social Sciences (SPSS)version 27.0.1 (IBM SPSS Statistics, Armonk, NY). Results The research study involved 107 participants, predominantly Saudi nationals (98.1%), with an average age of 22 years. Regarding the total cumulative dose (TCD), 40.2% had less than 50 mg/kg, 33.6% had between 50 and 100 mg/kg, and 15.9% had more than 100 mg/kg. The majority (73.8%) did not stop using isotretinoin. The average Ocular Surface Disease Index (OSDI) score, indicating ocular surface disease symptoms, was 26.78. There was no significant association between gender, dose/duration of isotretinoin, TCD, and age, and OSDI scores. However, participants with severe OSDI scores were more likely to have worsened pre-existing eye symptoms compared to those with non-severe OSDI scores (35.1% versus 11.4%, p = 0.011). Conclusions This study contributes to the understanding of the impact of isotretinoin usage on ocular surface health. While no significant associations were found between gender, dose, duration, TCD, and age, and OSDI scores, participants with pre-existing eye symptoms were more likely to experience worsened symptoms during isotretinoin treatment.

Ocular surface disease: a known yet overlooked side effect of topical glaucoma therapy.

Ocular surface disease (OSD), a disorder affecting the lacrimal and meibomian glands and the corneal and conjunctival epithelium, is a well-known complication of topical glaucoma therapy. OSD can present as a new or pre-existing condition that virtually any anti-glaucoma formulation can exacerbate. As such, both glaucoma and OSD frequently coexist. Typical OSD symptoms include ocular discomfort, redness, burning, and dryness, whereas signs include periorbital and eyelid skin pigmentation, conjunctival scarring, and superficial punctate keratitis. Pressure-lowering eyedrops can cause toxic, allergic, and inflammatory reactions on the ocular surface. The latter can result from either preservatives or direct toxicity from the active molecule. Although usually mild, OSD can cause significant symptoms that lead to poor quality of life, decreased compliance to therapy, glaucoma progression, and worse visual outcomes. Given the chronic nature of glaucoma, lack of curative therapy, and subsequent lifelong treatment, addressing OSD is necessary. This manuscript aims to provide an up-to-date overview of OSD's signs, symptoms, and pathogenic mechanisms from glaucoma therapy toxicity.

Effect of Treatment with Topical Azithromycin or Oral Doxycycline on Tear Film Thickness in Patients with Meibomian Gland Dysfunction: A Randomized Controlled Trial.

Purpose: This prospective, randomized, observer-masked, parallel-group study aimed to compare the effect of topical azithromycin and oral doxycycline on tear film thickness (TFT) and signs and symptoms of ocular surface disease (OSD) in patients with meibomian gland dysfunction (MGD). Methods: Patients were randomized to either receive topical azithromycin or oral doxycycline. After a baseline visit, three follow-up visits at intervals of 2 weeks were scheduled. Main outcome of the study was change in TFT as measured with ultrahigh resolution optical coherence tomography. Results: Twenty patients were included in the analysis. TFT significantly increased in both groups (P = 0.028 vs. baseline) with no difference between the groups (P = 0.096). As secondary outcomes, ocular surface disease index (OSDI) score and composite signs of OSD significantly decreased in both groups (P = 0.023 for OSDI and P = 0.016 for OSD signs vs. baseline). While eye-related adverse events (AEs) occurred more frequently in the azithromycin group, systemic AEs were more common in the doxycycline group. Conclusions: Both treatments improved signs and symptoms of OSD in patients with MGD with no difference between the groups. Due to the higher frequency of systemic side effects of doxycycline, azithromycin eye drops seem to be an alternative with comparable efficacy. Clinical Trial Registration number: NCT03162497.

Use of a Cationic Emulsion of Latanoprost to Treat Glaucoma Patients with Ocular Surface Disease: A Preclinical Review.

Prostaglandin analogue topical medications are one of the most effective therapeutic approaches for the chronic management of glaucoma and ocular hypertension, through the reduction of elevated intra ocular pressure (IOP). While many of the first generations of anti-glaucoma eye drops were preserved with benzalkonium chloride, their repeated use may induce chronic ocular surface toxicity that leads to ocular surface disease (OSD) signs and symptoms. As a result, soft-preservatives and preservative-free formulations have been developed with the goal to avoid the long-term iatrogenic toxicity of the preservative agents. In addition, it has been suggested that OSD and its associated inflammation may negatively impact the efficacy of the IOP-lowering medications, including treatment adherence and compliance. Hence, it may be particularly interesting that glaucoma medications can concomitantly protect and "heal" the ocular surface and its environment while lowering elevated IOP, for the greater benefit of glaucoma patients. The objective of the present review is to briefly present the preclinical data of the cationic oil-in-water emulsion of latanoprost (latanoprost-CE) to shed some light on its mechanisms of action. It overall supports the following hypothesis: the restoration of a healthy ocular surface environment and treatment of the OSD signs and symptoms will allow for an improved elevated IOP reduction and glaucoma management. This would be achieved with a once daily dosing regimen to preserve glaucoma patients' vision, ocular surface, and quality-of-life and wellness.

Prevalence of symptoms of ocular surface disease in patients of ophthalmic practices

Prevalence of symptoms of ocular surface disease in patients of ophthalmic practices

Prevalence of Dry Eye Symptoms and Associated Risk Factors among University Students in Poland.

The aim of the study was to demonstrate the prevalence and risk factors of dry eye symptoms (DES) among university students in Poland. A cross-sectional study survey was conducted among 312 Polish university students. The questionnaire consisted of the Ocular Surface Disease Index (OSDI), the 5-Item Dry Eye Questionnaire (DEQ-5) and questions regarding medical history and risk factors. According to the OSDI, more than half of respondents (57.1%) have symptoms of ocular surface disease. Time spent using electronic devices is correlated with scores gathered in both OSDI and DEQ-5 (p &lt; 0.001). There is a statistically significant dependence between psychotropics (p = 0.002), glucocorticosteroids usage (p = 0.026), the presence of depression (p &lt; 0.001), diabetes (p = 0.01) or allergy (p = 0.008) and dry eye symptoms proved in both questionnaires. Respondents with refractive errors and those living in metropolitan areas have a statistically higher symptom intensity(p &lt; 0.022). Stress felt by students is associated with higher DES risk. No correlation between DES and smoking habits was observed. The history of SARS-CoV-2 infection was associated with the severity of DES (p = 0.036). Pathogenesis of DES is multifactorial and its severity depends on several factors, both genetic and environmental. Its prevalence among the young population is underestimated. Determining risk factors will enable the implementation of appropriate prophylaxis and early diagnosis.

Ocular surface disease signs and symptoms of glaucoma patients and their relation to glaucoma medication in Finland.

To evaluate the prevalence of ocular surface disease (OSD) signs and symptoms of glaucoma patients in private clinics in relation to topical glaucoma treatment and to compare them to non-glaucomatous population. A multicenter, cross-sectional study consisting of private ophthalmology clinic visits in southern Finland. Glaucoma patients had a diagnosis of primary open-angle glaucoma, pseudoexfoliation glaucoma, pigmentary glaucoma, or treated ocular hypertension. Control patients had no prior or current use of glaucoma medication. Recorded parameters included OSD signs and symptoms, used glaucoma medications during the past 6 months, and the product name, type, and duration of used antiglaucoma drugs. Glaucoma patients (n = 564) showed higher severity of OSD sign parameters excluding Schirmer's test, as well as increased dry eye sensation compared to controls (n = 51). Beta-blockers and preservative-free prostaglandins had the smallest effect on all parameters. The increasing number of active compounds and administered eye drops per day showed an association with increasing severity of OSD signs, as well as dry eye and foreign body sensation. Duration of glaucoma medication showed no significant association with OSD signs or symptoms. Glaucoma patients show higher prevalence of OSD signs and dry eye sensation compared to non-glaucomatous population. The use of preserved glaucoma medication, as well as high number of active compounds and eye drops increase the severity of these parameters. There are significant differences between the types of glaucoma medication used, and therefore the selection of them is important especially in patients suffering from OSD.

Randomised, Single Blind, Controlled, Three-Month Clinical Trial on the Evaluation and Treatment of the Ocular Surface Damage Following Phacoemulsification.

Background: To determine efficacy of two lacrimal substitutes on signs and symptoms of ocular surface disease after phacoemulsification; to determine impact of surgery on patients’ vision related quality of life. Monocentric, randomised, physician blinded, three parallel groups clinical trial. Design and Methods: Patients in the operative list for phacoemulsification have been screened for eligibility; they underwent (at time 0, 15, 45 and 90 days): slit lamp examination; tear film break-up time (BUT); corneal staining; tear volume; 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ); Ocular Surface Disease Index (OSDI). Treatments to be compared were: 1. standard of care-SOC (lomefloxacine and tobramicine/dexamethasone fixed combination 4 times a day for 2 weeks), 2. SOC + carboxymethylcellulose sodium 0.5% and glycerin 0.9%, 3. SOC + Sodium Hyaluronate 0.15%. Study treatment started at T15. Groups were compared with parametric or nonparametric tests, and with Pearson’s χ2 test. Correlation between continuous variables was assessed by means of Pearson’s or Spearman’s coefficient. Results: Fifty-three patients were enrolled. At 45 and at 90 days from surgery, the group receiving lacrimal substitutes presented better BUT and Schirmer I test (p = 0.009, <0.001, <0.001 and 0.001, respectively); dry eye presence showed significant difference by group at time 90 (p = 0.019). General vision, near activity and vision-specific dependency subscales improved after surgery (p = <0.001, 0.004 and 0.048, respectively). At 45 and 90 days from surgery, the OSDI score significantly changed (p < 0.001).Conclusions: Cataract surgery causes the onset or the worsening of dry eye. Use of artificial tears can significantly reduce symptoms and signs of dry eye in patients after phacoemulsification.

Treatment of open-angle glaucoma and ocular hypertension with preservative-free tafluprost/timolol fixed-dose combination therapy: 6 case reports and clinical outcomes

BackgroundTreatment of open angle glaucoma (OAG) and/or ocular hypertension (OHT) focuses on achievement of target intraocular pressure (IOP), with the objective of slowing disease progression. However, ocular surface health is an important consideration in the optimization of treatment. We report 6 patient cases in which enhanced IOP control was achieved following appropriate management of ocular surface inflammation and a therapeutic switch to the preservative-free (PF) tafluprost (0.0015%)/timolol (0.5%) fixed-dose combination (FC).Case presentationSix patient cases, aged 48–74 years, presented with OAG or OHT. Each patient had signs and symptoms of ocular surface disease (OSD). Cases 1–3 were each receiving maximal medical therapy for OAG; regimens comprising prostaglandin analogue (PGA), β-blocker, carbonic anhydrase inhibitor (CAI) and α-2 agonist agents (including treatments containing preservative agent). Cases 1 and 2 reported IOP values ≥23 mmHg in each eye, and wide IOP fluctuations were identified when reviewing patient data concerning case 3 (11–20 mmHg). Maximal therapy was ceased and PF tafluprost/timolol FC was initiated, after which the signs and symptoms of OSD were improved and IOP was reduced (≤18 mmHg for cases 1–3) and stabilized. Cases 4 and 5 were diagnosed with OAG and case 6 had OHT. Each had symptoms and signs of OSD and were treated with a preserved PGA monotherapy (latanoprost 0.005% or bimatoprost 0.03%). At presentation, IOP was 24 mmHg in both eyes (case 4), ≥18 mmHg (case 5) and ≥ 22 mmHg (case 6). Following a switch to the PF tafluprost/timolol FC, OSD symptoms were improved and IOP was 14 mmHg (both eyes; case 4), ≤14 mmHg (case 5) and 16 mmHg (both eyes; case 6).ConclusionsIn addition to IOP-lowering efficacy, approaches to the management of OAG and OHT should consider the impact of treatment tolerability and the susceptibility of these patients to OSD. The presence of ocular surface inflammation appears to be detrimental to adherence and therefore to the effectiveness of topical medications. Addressing OSD through the use of PF FC formations, such as the PF tafluprost/timolol FC, reduces exposure to potentially toxic agents and facilitates improvements in IOP control.

Ocular Surface Disease Signs and Symptoms in Patients with Pseudoexfoliative Glaucoma: A Case-Control Study.

Purpose: The present study evaluates the differences in the prevalence of the signs and symptoms of ocular surface disease (OSD) in patients with PEX glaucoma (PEXG), compared to other glaucoma types (non-PEXG). Methods: Patients with non-PEXG and PEXG were prospectively examined for the presence and severity of OSD signs and questioned for symptoms using the OSDI (ocular surface disease index) questionnaire. Results: 116 patients were prospectively enrolled (58 non-PEXG and 58 PEXG). PEXG subjects who were older, had lower central corneal thickness (CCT) values, at a more advanced glaucoma stage and required more IOP lowering drops. OSD signs were prevalent in both groups: conjunctival hyperemia (74.5% non-PEXG vs. 94.8% PEXG), eyelid redness (70.7% vs. 96.6%), conjunctival (74.1% vs. 93.1%) and corneal fluorescein staining (81% vs. 93.1%) and abnormal TFBUT (82.8% vs. 87.9%). When adjusted for potential confounders, (older age, thinner CCT, more advanced glaucoma in PEXG) eyelid redness remained the only parameter significantly associated with PEXG, being 11 times more likely to occur in this group (p = 0.037). Conclusion: Subjects with PEXG presented a higher frequency of signs of OSD compared to other glaucoma types. When accounting for confounding factors, the only difference between the groups was the significantly higher presence (11 times more likely) of eyelid redness in PEXG, suggesting, in addition to glaucoma treatment, the impact of PEX on ocular surface integrity.

Evaluation of ocular surface disease symptoms and patient satisfaction in dry eye disease after 84 days of treatment with preservative‐free eye drops containing sodium hyaluronate and trehalose

AbstractPurposeDry eye disease (DED) has a multifactorial etiology, including insufficient tear production and/or excessive tear evaporation linked to multiple conditions. A preservative‐free eye drop formulation containing sodium hyaluronate and trehalose (SH‐THL, Thealoz® Duo) capitalizes on the bioprotectant properties of trehalose. This study evaluated the improvement of ocular surface disease (OSD), dry eye signs and symptoms, treatment satisfaction in patients with DED receiving SH‐THL.MethodsMulti‐center, international, non‐interventional prospective survey lasting 84 days with up to 2 post‐baseline visits in up to 310 adult subjects with clinically confirmed DED requiring artificial tears. Clinical signs with Schirmer Test, tear Break Up Time, hyperemia, dry eye symptoms with OSDI® scale and the five‐item dry eye questionnaire (DEQ‐5) as well as patient satisfaction were assessed at baseline, visit 1 (28 days) and 2 (84 days). SH‐THL was to be instilled when needed. The number of eye drops instilled per day was determined using the Kali Care Drop Meter (n=42).ResultsData from 238 patients were analyzed. 83.2% were women, the mean age was 57.9 ± 15.1 years. At baseline, the overall OSDI was 42.2 ± 19.9 and 61.3% of patients had severe OSDI. The DEQ‐5 score was 12.4±4.1 and the patient treatment satisfaction score was 6.4 ± 2.1. The OSDI significantly improved (p &lt; 0.001) after 84 days. The DEQ‐5 score significantly improved at visit 1, persisting until visit 2 (both p &lt; 0.001) with a statistically significant (p = 0.002) difference between visit 1 and 2. Patient satisfaction with treatment significantly improved (p &lt; 0.001) at visit 1 and 2 compared to baseline. All clinical signs significantly improved after 84 days of SH‐THL.ConclusionsResults confirm that continued use of eye drops containing SH‐THL reduced DED signs and symptoms, OSDI scores, and result in a very high patient satisfaction.

Comparison between therapeutic effects of 0.18% sodium hyaluronate and 1% carboxymethyl cellulose on ocular surface damage induced by anti-glaucoma medications

Purpose This study was conducted to compare the therapeutic effect of 1% carboxymethyl cellulose (CMC) and 0.18% sodium hyaluronate (SH) on ocular surface damage induced by various anti-glaucoma medications. Patients and methods The study included 100 patients who were diagnosed as having primary open-angle glaucoma, normal tension glaucoma, or ocular hypertension and were on anti-glaucoma drugs. The patients were divided in two groups: group A patients received 1% CMC, whereas group B patients received 0.18% SH for 3 months. The severity of ocular surface disease symptoms was assessed by the ocular surface disease index (OSDI) questionnaire. Ocular examination with tear film break-up time, fluorescein staining, Schirmer’s test, and conjunctival impression cytology was performed sequentially on days 0, 30, and 90. Results Both CMC-treated and SH-treated groups showed improvement in the OSDI scores at days 30 and 90. However, the OSDI scoring was statistically significantly better in the SH group at both follow-up intervals (P<0.05). Fluorescein staining improved significantly with SH compared with CMC at day 30 (P<0.03). Schirmer’s test, tear film break-up time, and conjunctival impression cytology improved in both drugs. However, the difference was not statistically significant (P>0.5). Conclusion Both SH and CMC improved the symptoms and signs of ocular surface damage caused by the preservatives used in anti-glaucoma medication. However, SH showed faster efficacy than the CMC-based formulation.

OCULAR SURFACE DISEASE AMONG PATIENTS WITH OPEN ANGLE GLAUCOMA USING TOPICAL ANTI-GLAUCOMA MEDICATIONS

Objective: To determine the frequency of ocular surface disease among patients with open angle glaucoma using topical antiglaucoma medications presenting at a tertiary care eye hospital.&#x0D; Study Design: Cross-sectional analytical study.&#x0D; Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi, from May 2019 to Jan 2020.&#x0D; Methodology: One hundred and eighty patients aged 18 or more, with open angle glaucoma using any of the topical antiglaucoma medications including preparations of dorzolamide, brimonidine, timolol, levobunolol, betaxolol, latanoprost, travoprost, bimatoprost or a combination of these for more than six months took part in the study. Ocular surface disease index was used to assess the presence and severity of ocular surface disease.&#x0D; Results: Out of 180 patients of glaucoma managed with topical anti-glaucoma medications, 83 (46.1%) did not show presence of ocular surface disease when ocular surface disease index was administered. Twenty-nine (16.1%) patients had mild symptoms, 17 (9.4%) had moderate symptoms while 51 (28.3%) patients reported severe symptoms of ocular surface disease. Advancing age and longer duration of treatment with topical anti-glaucoma medications had statistically significant association with the presence of ocular surface disease (p-value &lt;0.05).&#x0D; Conclusion: Presence of ocular surface disease was a common finding among patients using topical agents for the management of glaucoma. Advancing age and prolonged use of anti-glaucoma medication emerged as risk factors statistically related to the presence of ocular surface disease.

Patient-reported outcome measures for a large cohort of serum eye drops recipients in the UK.

Serum eye drops (SED) are an important treatment for patients with chronic and severe ocular surface disease (OSD). Despite a long history of use, there is a paucity of information on patient-reported outcomes, particularly comparing autologous SED (Auto-SED) and allogeneic SED (Allo-SED). National Health Service Blood and Transplant is the national provider of SED service for patients in the UK. To evaluate and compare patient-reported outcome measures (PROMs) in patients receiving Auto-SED and Allo-SED for severe OSD. PROMs were retrospectively collected from all new patients commencing treatment with Auto-SED and Allo-SED between January 2017 and September 2018, using the Ocular Surface Disease Index (OSDI) 12-item questionnaire. A linear mixed model was used to evaluate the change in OSDI scores between baseline and follow-up. During the study period, 279 patients who received either Auto-SED (n = 71) or Allo-SED (n = 208) were included in the analysis. Baseline and follow-up OSDI scores were available for 161 of these (49 Auto-SED and 112 Allo-SED). There was a significant reduction in mean OSDI score for both Auto-SED (59.06-24.63, p < 0.001) and Allo-SED (64.21-34.37, p < 0.001). There was no significant difference between Auto-SED and Allo-SED patients in terms of the reduction in the OSDI score (p = 0.27). Both Auto-SED and Allo-SED were associated with improvements in the quality of life of patients with chronic and severe OSD. Auto-SED and Allo-SED were equally effective in relieving the symptoms of OSD.

Prevalence of Ocular Surface Disease Symptoms in High School Students in Monterrey, Mexico.

To determine the prevalence of dry eye disease symptoms and contact lens wear in Mexican high school students. A cross-sectional association study included a group of high school students who were selected from a random sampling of classrooms. The authors used the Ocular Surface Disease Index (OSDI) questionnaire as a surrogate measure for dry eye disease symptoms, and contact lens wear was also investigated. Seven hundred fifty-nine students with a mean age of 16.12 ± 0.96 years were surveyed and 55.7% of the students were girls (423 of 759). The average OSDI score was 25.11 ± 20.61 points. Girls had higher scores (28.25 ± 21.48 points) than boys (21.14 ± 18.74 points), and the difference was statistically significant (P < .001). Forty-three students (6.1%) wore contact lenses and had higher OSDI scores (34.26 ± 23.13 and 24.51 ± 20.31 points, respectively) and the difference was also statistically significant (P = .002). Symptoms of mild and moderate dry eye disease are prevalent in high school students and, as reported in previous studies, girls are more affected than boys.

The Effect of Glaucoma on the Quality of Patient’s Life

Abstract Glaucoma is a chronic, progressive opticopathy with morphological optic disc changes and visual field disturbances. Visual field disturbances change the patient’s life habits. Medical as well as surgical treatments also disturb patients` activities of daily living. According to this, glaucoma is the disease which affects quality of patient’s life (QQL). Visual field (VF) evaluation is very important in glaucoma disease diagnostic process. Location of the VF defects also have an impact on the QOL. Patient`s daily activities, such as walking, low light condition adaptation, peripheral seeing of the objects, can be affected by glaucoma progression and with VF defects. All social, religious, cultural and traveling events are more difficult for the severe glaucomatous patients (MD&lt;-12dB) in comparison with mild glaucomatous, defined as patients with MD &gt; −6 dB. Every day usage of the local antuglaucomatous therapy disturbs patients’ QOL.
