Purpose: Early detection of sight-threatening disorders by technological applications like teleophthalmology and prompt treatment can help decrease visual impairment. This study evaluated the role of teleophthalmology in underserved rural areas along with cost-saving estimates for the end user. Methods: A prospective, observational, cross-sectional hospital-based study was conducted over 3 months. First 1000 teleconsultations were included. None of the patients denied providing informed consent. The patients were consulted at the eight vision centers and three satellite centers of the hospital in the nearby rural and tribal regions closer to their residential places. These vision and satellite centers were connected to the base hospital like a hub and spoke model with a teleophthalmology network. Results: Cataract (n = 301, 30.1%) and refractive error (n = 290, 29%) were the most common diagnosis. 42.1% of patients were referred to base hospital for further evaluation. Thus, a total of 57.9% of patients were not required to visit the base hospital for initial consultation, saving time and money. Furthermore, 15.1% of patients were provided medical treatment at the vision center and satellite center, which helped in making teleophthalmology cost-saving for the patients. An average of Rs. 621/- were saved per patient for the community in our study. Conclusion: Networked teleophthalmology model can be an affordable and feasible tool for providing eye care delivery services in rural and tribal regions of Gujarat and the whole country, especially for the end user. Thus, it may be a workable model in ophthalmology practice with substantial cost saving to the community. [ABSTRACT FROM AUTHOR]

Objectives: To observe patterns of Pediatric eye diseases over five years 2015-19, to improve management of ophthalmic pediatric units in the developing countries. Methods: It was an observational, cross-sectional study carried out in a tertiary eye care Hospital, Karachi. Records of the children under 16 years of age from 2015 to 2019 were retrieved. Inclusion criteria included complete records with age, gender of the children, symptoms, examination, investigation if necessary, and diagnosis. All incomplete records were excluded. Results: A total of 35348 records with 55.17% boys and 44.82% girls were analyzed. Similar gender difference was reflected in disease frequency. Seven percent of the children did not have detectable ocular pathology. Conjunctivitis, refractive errors and squint were the three most common ocular morbidities observed in decreasing order of frequency as 32.67%, 20.08% and 14.7% respectively. Cataract was present in 4.51%, Corneal disease in 4.11%, Retinal pathology in 1.04%, Glaucoma in 0.49% cases; but Retinoblastoma was present in 55 cases and ROP in 4 cases only. Almost 60% of the children had simple ocular problems like conjunctivitis, refractive error and absence of any pathology. Conclusion: Majority of the children attending pediatric ophthalmology had simple problems manageable at primary health facility level. Strengthening of the primary health care facility will reduce considerable burden of pediatric unit at the tertiary level. Optometrists and orthoptists are important members of the team for refraction and squint management. [ABSTRACT FROM AUTHOR]

Background: The development of human resources for eye health (HReH), aimed at achieving a 25% reduction in visual impairment by the year 2020, was one of the VISION 2020 objectives. Aim: To assess HReH in the public sector of KwaZulu-Natal (KZN), and its effect on the accessibility of eye care in the province. Setting: All public eye facilities in KZN. Methods: A quantitative cross-sectional study using a close-ended questionnaire to assess distribution and outputs of HReH. At the end of the questionnaire, respondents gave general comments on their ability to provide services. Results: Human resource rates were 0.89 for ophthalmologists, 2.44 for cataract surgeons, 4.8 for optometrists and 4.7 for ophthalmic nurses per 1 million population. Most health facilities had some HReH working in them, albeit none had dispensing opticians. Regression analysis showed that 67.1% of variation in cataract surgery was because of the number of surgeons available. Cataract surgical rates were low with a waiting period of up to 18 months. In addition to the refractive error regression analysis of 33.7%, spectacle supply was low, with a backlog of up to 9 months in some facilities. Conclusion: Overall, HReH targets as per VISION 2020 and the National Prevention of Blindness have not been met in this region. Dispensing opticians are not employed in any of the province's health districts. An increase in the eye health workforce is necessary to improve the eye health outcomes for people dependent on public eye facilities. [ABSTRACT FROM AUTHOR]

Aim: To estimate the prevalence of visual impairment (VI) due to uncorrected refractive error (URE) and to assess the barriers to utilization of services in the adult urban population of Delhi.Materials and Methods: A population-based rapid assessment of VI was conducted among people aged 40 years and above in 24 randomly selected clusters of East Delhi district. Presenting visual acuity (PVA) was assessed in each eye using Snellen's "E" chart. Pinhole examination was done if PVA was <20/60 in either eye and ocular examination to ascertain the cause of VI. Barriers to utilization of services for refractive error were recorded with questionnaires.Results: Of 2421 individuals enumerated, 2331 (96%) individuals were examined. Females were 50.7% among them. The mean age of all examined subjects was 51.32 ± 10.5 years (standard deviation). VI in either eye due to URE was present in 275 individuals (11.8%, 95% confidence interval [CI]: 10.5-13.1). URE was identified as the most common cause (53.4%) of VI. The overall prevalence of VI due to URE in the study population was 6.1% (95% CI: 5.1-7.0). The elder population as well as females were more likely to have VI due to URE (odds ratio [OR] = 12.3; P < 0.001 and OR = 1.5; P < 0.02). Lack of felt need was the most common reported barrier (31.5%).Conclusions: The prevalence of VI due to URE among the urban adult population of Delhi is still high despite the availability of abundant eye care facilities. The majority of reported barriers are related to human behavior and attitude toward the refractive error. Understanding these aspects will help in planning appropriate strategies to eliminate VI due to URE. [ABSTRACT FROM AUTHOR]
