Yoga for Eye Disorders-A Systematic Review.

The management of intra-ocular pressure (IOP) is important for glaucoma treatment. IOP is recognized for showing seasonal fluctuation. Glaucoma patients can be at high risk of dry eye disease (DED). We thus evaluated seasonal variation of IOP with and without DED in glaucoma patients. This study enrolled 4,708 patients, with mean age of 55.2 years, who visited our clinics in Japan from Mar 2015 to Feb 2017. We compared the seasonal variation in IOP (mean ± SD) across spring (March–May), summer (June–August), fall (September–November), and winter (December–February). IOP was highest in winter and lowest in summer, at 14.2/13.7 for non-glaucoma without DED group (n = 2,853, P = 0.001), 14.5/13.6 for non-glaucoma with DED group (n = 1,500, P = 0.000), 14.0/13.0 for glaucoma without DED group (n = 240, P = 0.051), and 15.4/12.4 for glaucoma with DED group (n = 115, P = 0.015). Seasonal variation was largest across the seasons in the glaucoma with DED group. IOP was also inversely correlated with corneal staining score (P = 0.000). In conclusion, the seasonal variation was significant in most of study groups and IOP could tend to be low in summer.

Background. Breast cancer patients often use complementary and alternative medicine, but few prospectively collected data on the topic are available specifically for postmenopausal breast cancer patients. A large prospective study was therefore conducted within a noninterventional study in order to identify the characteristics of patients interested in integrative medicine. Methods. The EvAluate-TM study is a prospective, multicenter noninterventional study in which treatment with the aromatase inhibitor letrozole was evaluated in postmenopausal women with hormone receptor–positive primary breast cancer. Between 2008 and 2009, 5045 postmenopausal patients were enrolled at 339 certified breast centers in Germany. As part of the data collection process, patients were asked at the baseline about their interest in and information needs relating to integrative medicine. Results. Of the 5045 patients recruited, 3411 responded to the questionnaire on integrative medicine and took part in the analysis, 1583 patients expressed an interest in integrative medicine, and 1828 patients declared no interest. Relevant predictors of interest in integrative medicine were age, body mass index, tumor size, previous chemotherapy, and use of concomitant medications for other medical conditions. Interest in integrative medicine declined highly significantly (P < .001) with age (<50 years, 74.1%; 50-60 years, 54.1%; >65 years, 38.0%). Patients in favor of integrative medicine were significantly less satisfied with the information received about individual treatments and antihormonal therapy. Patients with interest in integrative medicine were more often interested in rehabilitation and fitness, nutritional counseling, and additional support from self-help organizations. These women were mostly interested in receiving information about their disease and integrative medicine from a physician, rather than from other sources. Conclusions. This study shows that a considerable proportion of postmenopausal breast cancer patients are interested in integrative medicine. Information about integrative medicine should therefore be provided as part of patient care for this group. It was found that receiving concomitant medication for other medical conditions is one of the main predictors for women not being interested in integrative medicine. This group of patients may need special attention and individualized information about integrative medicine. Additionally, most patients were interested in obtaining the relevant information from their doctor.

Understanding the Dual Dilemma of Dry Eye and Glaucoma: An International Review.

Background: Breast cancer patients make frequent use of complementary and alternative medicine (CAM), but few prospectively collected data are available specifically for postmenopausal breast cancer patients receiving adjuvant antihormonal therapy. The aim of the study was to identify the characteristics of patients who are interested in integrative medicine (IM). Methods: The EvAluate-TM study is a prospective noninterventional study, in which treatment with letrozole was evaluated in postmenopausal women with hormone receptor-positive primary breast cancer. 5,045 patients were enrolled at 339 certified breast centers. As part of the data collection process, patients were asked at the baseline about their interest in and information needs about IM. Results: 3,411 patients responded to the questionnaire on IM and took part in the analysis. 1,583 patients expressed an interest in IM. Relevant predictors of interest in IM were age, body mass index, tumor size, previous chemotherapy, and use of concomitant medications for other medical conditions. Interest in IM declined highly significantly (P < 0.001) with age. In addition, these women were mostly interested in receiving information about their disease from a physician. Conclusions: This study shows that postmenopausal women have a strong interest in IM. Information about IM should therefore be included in patient care for this patient group. Especially the patients receiving concomitant medication, which is one of the main predictors for women not being interested in IM, may need special attention. In addition, most patients were interested in obtaining the relevant information from their doctor, indicating that responsibility for this lies with the treating physicians.

Background: Sleep disorders and ocular conditions are prevalent health concerns with significant impact on the quality of life. However, the relationship between them remains underexplored. Additionally, therapeutic interventions targeting both sleep and eye health are explored. Materials and Methods: A prospective clinical study was conducted involving 500 participants aged between 30 and 65 years, recruited from an outpatient clinic specializing in sleep disorders and ophthalmology. Participants underwent comprehensive assessments including polysomnography for sleep disorders diagnosis and ophthalmic examinations for ocular condition evaluation. Sleep quality was assessed using standardized questionnaires, while ocular health was evaluated through clinical examination, including measurements of intraocular pressure, tear film break-up time, and retinal imaging. Statistical analyses were performed using Chi-square tests and logistic regression models to determine associations between sleep disorders and ocular conditions, adjusting for potential confounders. Results: Among the participants, 35% were diagnosed with sleep apnea, 25% with insomnia, 20% with dry eye syndrome, 15% with glaucoma, and 10% with diabetic retinopathy. Significant associations were found between sleep disorders and ocular conditions. Participants with sleep apnea were more likely to have dry eye syndrome (odds ratio [OR] = 2.5, 95% confidence interval [CI] = 1.8–3.4, P &lt; 0.001) and glaucoma (OR = 1.8, 95% CI = 1.3–2.5, P = 0.002). Similarly, insomnia was associated with dry eye syndrome (OR = 2.2, 95% CI = 1.5–3.1, P &lt; 0.001) and diabetic retinopathy (OR = 1.6, 95% CI = 1.1–2.3, P = 0.012). Conclusion: This study highlights the significant association between sleep disorders and ocular conditions, suggesting a potential bidirectional relationship.

=Theoretically, autologous serum eye drops (AS) have a potential advantage over traditional therapies based on the assumption that ASserve not only as a lacrimal substitute to provide lubrication, but also contain other biochemical components mimicking natural tears more closely. The application of AS in dry eye treatment has gained popularity as a second-line therapy in the treatment of dry eye.Published studies on the subject indicate that autologous serum could be an effective treatment for dry eye. To evaluate the efficacy and safety of AS compared to artificial tears for treating dry eye. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 3),Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE,(January 1950 to April 2013), EMBASE (January 1980 to April 2013), Latin American and Caribbean Literature on Health Sciences(LILACS) (January 1982 to April 2013), themetaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov(www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We also searched the Science Citation Index Expanded database (September 2013) and reference lists of included studies. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 15 April 2013. We included randomized controlled trials (RCTs) in which AS was compared to artificial tears in the treatment of dry eye in adults. Two review authors independently screened all titles and abstracts and assessed full-text articles of potentially eligible trials. Two review authors extracted data and assessed the methodological quality and characteristics of the included trials.We contacted investigators for missing data. For both primary and secondary outcomes, we reported mean differences with corresponding 95% confidence intervals(CIs) for continuous outcomes. We identified four eligible RCTs in which AS was compared with artificial tear treatment or saline in individuals (n = 72 participants)with dry eye of various etiologies (Sjögren’s syndrome-related dry eye, non-Sjögren’s syndrome dry eye and postoperative dry eye induced by laser-assisted in situ keratomileusis (LASIK)). The quality of the evidence provided by these trials was variable. A majority of the risk of bias domains were judged to have an unclear risk of bias in two trials owing to insufficient reporting of trial characteristics.One trial was considered to have a low risk of bias for most domains while another was considered to have a high risk of bias for most domains. Incomplete outcome reporting and heterogeneity in the participant populations and follow-up periods prevented the inclusion of these trials in a summary meta-analysis. For the primary outcome, improvement in participant-reported symptoms at one month, one trial (12 participants) showed no difference in participant-reported symptoms between 20% AS and artificial tears. Based on the results of two trials in 32 participants, 20% AS may provide some improvement in participant-reported symptoms compared to traditional artificial tears after two weeks of treatment. One trial also showed positive results with a mean difference in tear breakup time (TBUT) of 2.00 seconds (95% CI 0.99 to 3.01 seconds) between 20% AS and artificial tears after two weeks, which were not similar to findings from the other trials. Based on all other objective clinical assessments included in this review, AS was not associated with improvements in aqueous tear production measured by Schirmer's test (two trials, 33 participants), ocular surface condition with fluorescein (four trials, 72 participants) or Rose Bengal staining (three trials, 60 participants), and epithelial metaplasia by impression cytology compared to artificial tears (one trial, 12 participants). Data on adverse effects were not reported by three of the included studies. In one study, there were no serious adverse events reported with the collection of and treatment with AS. Overall there was inconsistency in the possible benefits of AS in improving participant-reported symptoms and TBUT and lack of effect based on other objective clinical measures. Well-planned, large, high-quality RCTs are warranted, in different severities of dry eye and using standardized questionnaires to measure participant-reported outcomes and objective clinical tests as well as objective biomarkers to assess the benefit of AS therapy for dry eye.

The XEN® gel stent reduces intraocular pressure (IOP) in glaucoma. XEN®-45 is widely used; the newer XEN®-63 has a larger lumen targeting potentially lower IOP outcomes. We retrospectively compared the first 15 XEN®-63 cases to 15 matched XEN®-45 controls. With a preoperative IOP of 18.1 ± 3.9 mmHg (mean ± SD) and a final IOP of 9.1 ± 2.0 mmHg, XEN®-63 implantation resulted in an IOP reduction of 44.6 ± 16.5%. Similarly, with a preoperative IOP of 18.3 ± 4.5 mmHg and a final IOP of 10.3 ± 2.1 mmHg, XEN®-45 implantation resulted in an IOP reduction of 40.1 ± 17.2%. The median follow-up period was 204 days (range 78-338 days) for the XEN®-63 group and 386 days (range 99-1688 days) for the XEN®-45 group. In total, 5/15 eyes of each group underwent open conjunctival bleb revision within the period of observation. Three eyes of the XEN®-63 group had secondary glaucoma surgery. One eye in the XEN®-63 group and three eyes in the XEN®-45 group required a restart of antiglaucomatous medication. In conclusion, both stents effectively lower IOP and medication. XEN®-63 achieved a slightly lower IOP over a short follow-up. Complication and revision rates were similar.

The utility of Goldmann applanation tonometry (GAT) for monitoring intraocular pressure (IOP) in open-angle glaucoma (OAG) patients with a history of laser refractive surgery was investigated by comparing IOP fluctuations measured using GAT and dynamic contour tonometry (DCT) on the same day. In this retrospective study, patients were divided into one of two subgroups according to IOP fluctuation values using GAT: 43 eyes in the low IOP fluctuation group (LIFG [GAT fluctuation ≤1.7 mmHg]); and 55 eyes in the high IOP fluctuation group (HIFG [GAT fluctuation >1.7 mmHg]). IOP fluctuation was defined as the standard deviation of all IOP values during follow-up. IOP parameters using GAT were compared with those of DCT. Correlation analyses were performed among IOP parameters, and between IOP fluctuation and associated factors including central corneal thickness, corneal curvature, and axial length. All IOP parameters demonstrated significantly high values in the HIFG compared with those in the LIFG. Mean and peak IOP using DCT were significantly higher than those using GAT in both groups. However, there were no significant differences in IOP fluctuation and reduction using both tonometry methods in the HIFG (p = 0.946 and p = 0.986, respectively). Bland-Altman analysis revealed similar fluctuations using GAT and DCT. In multivariate analyses, there was a significant correlation between fluctuations using GAT and DCT in the HIFG (p = 0.043). These results suggest that IOP monitoring using GAT is a reliable method of monitoring IOP change in glaucoma patients with a history of laser refractive surgery, especially those exhibiting high IOP fluctuation. Nevertheless, several factors, including central corneal thickness, corneal curvature, and axial length, should be considered when using GAT for IOP monitoring.

Topical corticosteroids for dry eye.

The pregabalin is approved for the management of persistent pain. The aim of this study is to assess the advantages and disadvantages of the use of pregabalin in eye pain management. The PubMed, Cochrane Library, Embase, and Web of Science databases were searched until January 2022 for randomized controlled trials. Randomized, double-blinded trials comparing pregabalin with placebo in eye pain management were included. The primary outcome was visual analog scale or numerical rating scale at acute (24 hours) and chronic (≥7 days after surgery) timepoints. The secondary outcomes were analgesic medication requirements and pregabalin-related complications (nausea, vomiting, dizziness, and headache). We also compared the effect of pregabalin on dry-eye syndrome. Six relevant articles were identified that studied the use of pregabalin as pain relief for photorefractive keratectomy (n = 2), laser epithelial keratomileusis (n = 1), laser-assisted in situ keratomileusis (n = 1), eyelid surgery (n = 1), and dacryocystorhinostomy (n = 1). Pregabalin was associated with a significant reduction in pain scores (95% confidence interval = -0.41 [-0.76--0.06]) 24 hours after surgical procedures. The data were insufficient to draw conclusions regarding dry eye symptoms. Because of the high heterogeneity of outcomes regarding adverse effects, there is no conclusion regarding the safety of pregabalin in eye pain. Pregabalin reduced acute eye pain but had no significant effect on long-term analgesia after ophthalmological surgery in adults. It had no effect on dry-eye symptoms after ocular surgery. Further studies on the safety of pregabalin in eye pain management are required to draw solid conclusions.

Primary open-angle glaucoma combined with dry eye syndrome is the leading cause of irreversible blindness. Complement system remains nearly unexplored in this disorder. The aim of our study was to evaluate the parameters of complement system in primary open-angle glaucoma and dry eye syndrome among elderly persons. The study was conducted at the S. Fedorov Center of Eye Microsurgery (Tambov Branch), and enrolled 62 patients aged 60 to 74 years with primary open-angle glaucoma combined with dry eye syndrome, and 33 patients free of this pathology. The blood complement system was studied by hemolytic method and enzyme immunoassay, and the C1 inhibitor was studied by chromogenic method. To assess possible contribution of the complement system components to the mentioned eye disorder, appropriate odds ratios were calculated, according to the generally accepted method. The study of blood complement system in elderly patients with combined primary open-angle glaucoma and dry eye syndrome have shown, first of all, high C3a level (up to 106.2±3.9 ng/ml), increased contents of C5a (4.5±0.2 ng/ml), and factor H (215.9±5.2 mcg/ml), along with decreased C1 inhibitor (to 168.4±6.1 mcg/ml). In the age-matched control group, the contents of appropriate plasma complement factors were, respectively, 45.2±4.0 ng/ml; 3.1±0.2 ng/ml; 141.5±4.3 mcg/ml; 237.9±5.8 mcg/ml, showing significant difference for all these parameters. An important pathogenetic role of C3a component, C5a component, factor H, and the C1 inhibitor in development of combined primary openangle glaucoma with dry eye syndrome was confirmed by the values of odds ratio (OR) with maximum value for the C3a component (OR 4.035, CI 3.640-4.283, p &lt; 0.0001), which indicates increased risk of developing the mentioned ophthalmopathology in old age. High odd ratios were also characteristic of C5a blood components (2.946; CI 2.618-3.547), C3 (2.821; CI 2.453-3.264), factor H (2.765; CI 2.431-3.148). Less significant changes were revealed for other complement components thus suggesting only marginal association with development of primary open-angle glaucoma with dry eye syndrome in old age This indicates that the development of primary open-angle glaucoma with dry eye syndrome is associated with activation of these factors of the complement system. The revealed features of the complement system will enable us for more effective diagnostics of these combined eye disorders.

Oxidative stress represents one of the main factors driving the pathophysiology of multiple ophthalmic conditions including presbyopia, cataracts, dry eye disease (DED), glaucoma, age-related macular degeneration (AMD) and diabetic retinopathy (DR). Currently, different studies have demonstrated the role of orally administered nutraceuticals in these diseases. For instance, they have demonstrated to improve lens accommodation in presbyopia, reduce protein aggregation in cataracts, ameliorate tear film stability, break up time, and tear production in dry eye, and participate in the avoidance of retinal neuronal damage and a decrease in intraocular pressure in glaucoma, contribute to the delayed progression of AMD, or in the prevention or treatment of neuronal death in diabetic retinopathy. In this review, we summarized the nutraceuticals which have presented a positive impact in ocular disorders, emphasizing the clinical assays. The characteristics of the different types of nutraceuticals are specified along with the nutraceutical concentration used to achieve a therapeutic outcome in ocular diseases.

Use of integrative medicine (IM) is prevalent in children, yet availability of training opportunities is limited. The Pediatric Integrative Medicine in Residency (PIMR) program was designed to address this training gap. The PIMR program is a 100-hour online educational curriculum, modeled on the successful Integrative Medicine in Residency program in family medicine. Preliminary data on site characteristics, resident experience with and interest in IM, and residents’ self-assessments of perceived knowledge and skills in IM are presented. The embedded multimodal evaluation is described. Less than one-third of residents had IM coursework in medical school or personal experience with IM. Yet most (66%) were interested in learning IM, and 71% were interested in applying IM after graduation. Less than half of the residents endorsed pre-existing IM knowledge/skills. Average score on IM medical knowledge exam was 51%. Sites endorsed 1–8 of 11 site characteristics, with most (80%) indicating they had an IM practitioner onsite and IM trained faculty. Preliminary results indicate that the PIMR online curriculum targets identified knowledge gaps. Residents had minimal prior IM exposure, yet expressed strong interest in IM education. PIMR training site surveys identified both strengths and areas needing further development to support successful PIMR program implementation.

Purpose: The purpose of this study is that research eye health in Filipino and Korean male students for comparative analysis of prevalence and risk factors. Method: The s ubjects of this study were 196 male s tudents, aged 17, from Korea and the Philippines and it was investigated whether they have dry eye syndrome, subjective symptoms, conjunctivitis, and pterygium or not. The McMonnies questionnaire was used for measuring dry eye syndrome. Subjective symptoms, video display time and sun exposure time were added to the questionnaire items; while conjunctivitis and pterygium were confirmed by visual examination. Results: The average sunlight exposure time per day excluding school hours were 2 hours and 12 minutes for the Filipino students and 1 hour and 1 minute for the Korean students. Sunlight exposure time had a significant effect on the Filipino students with dry eye syndrome, subjective symptoms, conjunctivitis, and pterygium, but multimedia viewing time did not. In contrast, the sunlight exposure time and video display time didn’t effect to Korean students, excluding the scores on the McMonnies questionnaire. The Filipino students had a statistical difference in the occurring frequency of subjective symptoms, conjunctivitis, and pterygium in dry eye syndrome. Also they had the higher the scores on the McMonnies questionnaire and high prevalence of conjunctivitis and pterygium. Conclusion: It was identified that the Filipino students had their sunlight exposure time affecting their eye health, whereas the Korean students didn’t have. And it related to occurring frequency of conjunctivitis and pterygium in case of dry eye syndrome patients. Another analysis needs to be made of other risk factors besides sunlight exposure time analyzed by this study , which may affect the eye health of the Filipino students.
