ABSTRACT
Purpose: Assistive technology (AT) has recently received considerable attention around the world. Studies have shown poor access to assistive technology for visual impairment (ATVI) in schools for the blind in India. The present article aimed at designing a school?based model to improve AT access in schools and provide hands?on training, and identify types of ocular morbidities present among students. Methods: The vision rehabilitation (VR) team of a tertiary eye?care center visited schools for the blind as a part of community? based VR services. The team conducted a basic eye examination and assessed best?corrected vision acuity (BCVA) and provided VR services. Furthermore, two schools were selected to establish an ATVI learning center as a pilot model. Results: In total, 1887 students were registered for VR and obtained their disability certificates in 2019?20. Retina problems (25.7%), globe abnormalities (25.5%), optic nerve atrophy (13.6%), and squint (12.0%) were common ocular problems identified in students. Around 50.3% of students had BCVA ³ 1/60 in the better eye who would be benefited from visual?based AT, and the remaining students with visual substitution AT. Further, 20.8% of them who had near vision between N18 to N24 would be benefitted from large print books. Two schools were provided ATVI with support from the WHO. Familiarization, demonstration, and initial training for ATVI were carried out. Conclusion: A sizable number of the students would be benefitted from visual?based AT apart from visual substitutions AT. Students were interested to have such ATVI centers in the school for academic and non?academic skills development.
ABSTRACT
Purpose: In the mid?twentieth century, trachoma was endemic in the northwestern states of India. We aimed to generate recent estimates of prevalence of trachomatous inflammation, follicular (TF) and trachomatous trichiasis (TT) in ten suspected?endemic districts across seven previously hyper?endemic states and union territories for trachoma in India including Delhi, Rajasthan, Haryana, Punjab, Gujarat, Uttarakhand and the Andaman and Nicobar Islands. Methods: Population?based prevalence surveys were undertaken in 10 districts. In each of those districts, two?stage cluster sampling was used to select a sample of 2000 children aged 1–9 years and all adults aged ?15 years in the enumerated households from a total of 20 clusters per district. Consenting eligible participants were examined for trachoma by trained ophthalmologists using the World Health Organization’s simplified grading system. Data were analyzed at the district level. Results: A total of 13,802 households were surveyed in which 19,662 children were examined for TF and 44,135 adults aged ?15 years were examined for TT. District?level TF prevalence in 1–9?year?olds ranged from 0.1% in Bikaner (95% CI: 0.01–0.3) to 2.1% in Dholpur (95% CI: 1.6–2.8) and that of trichiasis ranged from 0.7 per 1000 in Pauri Garhwal (95% CI: 0.01–1.4) to 22.1 per 1000 (95% CI: 15.8–28.4) in Car Nicobar. In four districts (Car Nicobar, Dholpur, Hoshiarpur, Tonk), trichiasis prevalence in adults aged ?15 years was ?0.2%. Conclusion: TF was not a public health problem in any of the districts surveyed; thus, antibiotic mass drug administration is not needed. However, TT among adults was found to be above 0.2% in four districts; thus, further trichiasis surgery interventions at the public health level are warranted to achieve elimination. These findings will facilitate planning for elimination of trachoma as a public health problem in India.
ABSTRACT
Purpose: To examine the current provision and practice patterns of diabetic retinopathy screening (DRS) in Haryana. Methods: This was a descriptive cross?sectional survey in Haryana. All ophthalmologists registered with Haryana Ophthalmological Society in Haryana state were invited to participate on an online survey comprised of twenty questions exploring diabetic retinopathy screening provision, and barriers to screening services in Haryana. Results: The response rate was 82% (153/186). The majority (84%) of the eye care providers practiced in urban areas. Most ophthalmologists (89%, 136/153), considered diabetic retinopathy screening by non?ophthalmic human resource inappropriate because of technical feasibility issues (62%) followed by non?availability of trained staff (33%). Only half (54%) of the respondents had access to written protocols for the diagnosis and management of diabetic retinopathy in their practice. Barriers to optimize diabetic retinopathy screening were lack of knowledge or awareness among patients (95.5%), perception that eye complications were unlikely (76%) and cost of care (30%). Conclusion: Diabetic retinopathy screening practices are mainly opportunistic and urban?centric, likely delivering inequitable services for the rural populations in the state. The inclusion of other personnel in screening will require stakeholder engagement from all health professions and changing the perceptions of ophthalmologists about task shifting.
