Vision-Related Quality of Life Among Diabetic Retinopathy Patients in a Hospital-Based Population in the Sultanate of Oman.

Background: The global prevalence of diabetic retinopathy (DR) among individuals with diabetes is 22.27%. This highlights the likelihood of developing burden of retinopathy within the at risk population and can have a detrimental impact on an individual's quality of life (QoL). The aim of this study is to assess the vision-related QoL in individuals with (DR) in a hospital-based population in the Al-Buraimi governorate, Sultanate of Oman. Methods: The study was conducted in the Ophthalmology Outpatient Department of Al Buraimi Hospital and Polyclinic. This study enrolled 218 patients (114 males, 104 females) diagnosed with DR. The NEI-VFQ-25 questionnaire was adopted in this study. The patients were classified into different groups according to their type of diabetes and other relevant demographic information. Results: A total of 218 patients responded to the NEI-VFQ-25 questionnaire. The mean age of the participants was 57.49 ± 12.3 years, 52.3% were male, and 47.7% were female. The overall QoL score was 41.53± 20.8. Patients aged more than 75 years had the lowest QoL scores compared with the other age groups (p = 0.02). The results showed that the duration of diabetes had no significant impact on the overall QoL scores (p = 0.06). A higher QoL score was observed among patients with type II diabetes mellitus (DM) than with type I diabetes mellitus (p = 0.01). Patients diagnosed with proliferative DR (PDR) had a significantly lower QoL score than those diagnosed at other stages (p < 0.001). Conclusion: The QoL of the population with DR is negatively affected by various factors, including demographics, disease severity, and in patients with DM type II. It is important to consider these factors to enhance QoL in patients with DR. Regular evaluation of an individual's QoL is beneficial for both physicians and healthcare teams.

Profile of contact lens prescribing in GCC countries.

PURPOSE: This study aimed to report the pattern of contact lens prescribing from the Gulf Cooperation Council (GCC) countries. METHODS: Optometrists in the GCC region were contacted to participate in a web-based survey hosted on Qualtrics XM (Provo, Utah, USA). The survey methodology was adapted from the International Contact Lens Prescribing Consortium, and participants were asked to report their last five lens fits. It collected information on practitioner demographics (age, gender, nationality, qualification, country of practice, and number of years of experience), CL user demographics (age and gender) and on lens specific details such as lens type, lens design, lens material, replacement plan, and modality of lens wear. Descriptive statistics were used to analyse and report the data. RESULTS: This study reports 739 contact lens fits by 174 practitioners from six GCC countries. The average age of the patients was 29.72 ± 9.07 (Mean ± SD) years and 64 % of them were females. The majority (80.2 %) were fitted with soft contact lenses, with 59 % preferring silicone hydrogels, 20 % wearing them for cosmetic purposes and nearly half of them disposed of their lenses daily (55 %). Among the RGP lenses, 41 % were scleral lenses. This survey demonstrated a greater proportion of new lens fits (55 % vs. 37 %), disposable hydrogel lens use (21 % vs. 13 %), and a preference for cosmetic contact lenses (20 % vs. 4 %) compared to the international data. CONCLUSION: The pattern of CL prescriptions in the GCC region closely resembled the global trend. The survey observed a higher preference towards frequent replacement soft lenses, a greater proportion of silicone hydrogel lenses, a higher percentage of rigid lens fits, a greater affinity for cosmetic contact lenses, and a higher percentage of new fits. These trends suggest that contact lens prescription habits in the region are likely to continue evolving in the future.

Differences in Practitioner Experience, Practice Type, and Profession in Attitudes Toward Growing Contact Lens Practice.

OBJECTIVE: To investigate eye care practitioners' attitudes and perceptions toward potential interventions that can enhance contact lens (CL) practice across the world, and how this is influenced by their practice setting. METHODS: A self-administered, anonymized survey was constructed in English and then forward and backward translated into six more languages. The survey was distributed online via social media platforms and mailing lists involving reputed international professional bodies. RESULTS: In total, 2,222 responses from 27 countries with sufficient responses were analyzed (53% females, median age- 37 years). Most of the respondents were optometrists (81.9%) and 47.6% were from stand-alone/independent practices. Median working experience in CL prescribing was 11.0 years (IQR: 18.0, 4-22 years). Over two-third of them declared themselves to be very hopeful (22.9%) or hopeful (45.1%) about the future of their CL practice. Among the potential interventions proposed, continuous update of knowledge and skills and competently managing CL-related complications were rated the most important (median score: 9/10 for each). Practitioners working in national/regional retail chains expressed higher proactivity in recommending CLs (9/10) than those in local chains, hospitals, and universities (for all 8/10, P <0.05). National differences were also identified in eye care practitioner attitudes and perceptions ( P <0.05). CONCLUSIONS: The study provided important information to delineate a variety of elements characterizing CL practice across the world. These insights can serve as a basis to design strategies at national and international levels.

Barriers and Perception Towards Spectacle Wear among a Student Population of University of Buraimi, Oman.

OBJECTIVES: The study aimed to evaluate the barriers and perceptions towards spectacle wear among the student population of the University of Buraimi, Oman. METHODS: A descriptive, questionnaire-based and cross-sectional study was conducted between December 2017 and May 2018. Ophthalmic examination and a standard spectacle prescription protocol were used to identify those with inappropriate spectacle coverage. A self-designed and expert validated English-language questionnaire was utilised. A chi-square test was used to assess the association between the participants' types of perceptions and sociodemographic and refractive error-related profiles. RESULTS: In total, 275 students participated in the study (response rate: 17.19%) and 170 (61.8%) were having inappropriate spectacle correction. Only 26% of them used spectacles since the majority (73.5%) had never had their eyes examined before this study. Most perceived spectacle wear positively (53.5%), followed by some having negative (36.5%) or neutral (10.0%) perceptions. Those from a health science background including Nursing and Optometry had a higher positive perception towards spectacle wear than others (P = 0.012). The difference in the perception scores between myopic and hypermetropic refractive error groups was statistically insignificant (P = 0.882). CONCLUSION: The majority of the participants had had inappropriate vision corrections with spectacles and not undergone any prior ocular examinations. Few wore spectacles; however, these were inappropriate given their current refractive status. The reasons for spectacle non-wear were that either new spectacles had been ordered or spectacles were lost or broken. It is recommended that the school eye health initiative be extended to the university level. A holistic eye-health promotional approach toward integrating students, teachers and parents into this initiative can improve spectacle wear within the studied population.

Opportunities and threats to contact lens practice: A global survey perspective.

AIM: To understand the views of contact lens (CL) practitioners across the globe regarding what they perceive as opportunities and threats in CL practice. METHODS: A self-administered anonymised questionnaire, constructed in English and translated in six more languages, was distributed through reputed international professional bodies and academic institutions worldwide. The questionnaire included items on demographic characteristics, type of practice, and questions designed to explore practitioners' perspective on the future of their CL practice over the next five years. RESULTS: A total of 2408 valid responses were analysed. Multifocal CLs for presbyopia, CLs for myopia control, use of daily disposable (DD) CLs for occasional wear, and biocompatible materials to improve comfort were identified as promising areas of opportunities by practitioners (all 8/10). Respondents from North America, and Europe valued DDCLs for occasional wear moderately more favourable (Median: 9/10 for all) as compared to colleagues in Asia (Median: 8/10, p < 0.001), South America (Median: 8/10, p < 0.01), and Africa (Median: 8/10p < 0.01). Multifocal CLs for presbyopia was perceived as a better opportunity by practitioners in North America and Europe (Median: 9/10 for both), as well as in Australasia (Median: 8/10), in comparison to Asia, Africa, and Middle East (for all Median: 6/10, p < 0.001). Practitioners expressed concerns about the availability of CLs and CL prescriptions online without direct professional involvement (both 9/10). CONCLUSIONS: Overall, the most appealing opportunities for CL practice growth were identified in occasional use of DD CLs, biocompatible materials to reduce CL discomfort, multifocal CLs for presbyopia correction and management of myopia control with CLs. Lack of regulation in CL sales, especially online, seemed to be a constant threat. The insights from this study can be used to design targeted strategies to enhance CL practice across the globe and in specific geographical areas.
