AIM: To study clinical profile of amblyopia and also the outcomes of occlusion therapy among the amblyopes. METHODS: This was a hospital-based longitudinal study by design. Data were collected from April 2015 to April 2016 in Ophthalmology Department of Dhulikhel Hospital. Presenting visual acuity, chief complaint at presentation, age at presentation, refractive status, binocularity and fixation patterns were assessed in all the children with amblyopia. Improvement in visual acuity was also noted in all the subjects after occlusion therapy, which is a most commonly used modality of treatment for amblyopia. RESULTS: Among 1092 children examined during the study period, 60 (5.49%) were amblyopic. Among them, 35 (58.30%) were females and 25 (41.70%) were males. The mean age at presentation was 8.87±3.29y. Meridional amblyopia was the most prevalent subtype seen in 43.3% (n=26) of children followed by anisohypermetropic amblyopia (20%, n=12). The most common refractive error was astigmatism accounting for 58.30% of the total cases followed by hypermetropia (22.5%) and myopia (7.5%). Compliance with spectacle wear combined with occlusion therapy and active vision therapy was 73.3% (n=44). There was a statistically significant improvement in visual acuity of the amblyopic eyes after the different treatment strategies after 3mo (P=0.002). CONCLUSION: Prevalence of amblyopia and associated visual impairment is still a public health issue in developing countries like Nepal. Lack of awareness and lack of community or preschool vision screening for children lead to late presentation and significant visual impairment associated with the condition. The burden can easily be reduced with screening camps, timely referrals and proper interventions.

Abstract Background Refractive errors and visual impairment in southernmost China have not been reported previously. We aim to investigate and determine the age-specific prevalence of myopia, hyperopia, astigmatism, and visual impairment based on a large population cross-sectional study in Hainan area of southernmost tropical province in China. Methods A population-based sample of 31,524 children aged 6–15 years from Hainan was assessed. Non-cycloplegic autorefraction and visual acuity (VA) analyses were performed on all participants and a subgroup of participants undergoing cycloplegia. Results Of all participants, 23.0% presented uncorrected VA (UCVA) was worse than 20/40 in worse eye, 6.0% presented mild presenting visual acuity impairment (PVAI), 7.0% presented moderate PVAI, 0.2% presented severe PVAI in the better eye, and 46.9% presented abnormal UCVA [worse than 20/25 (≥ 6, < 8 years old) and worse than 20/20 (≥ 8 years and older)] at least in one eye. The overall prevalence of myopia [spherical equivalent (SE) ≤  − 0.50 D] and high myopia (SE ≤  − 6.00 D) were 46.0%, 1.0% respectively. Hyperopia [SE ≥  + 1.00 D (≥ 7 years old) and SE ≥  + 2.00 D (≥ 6, < 7 years old)] and significant hyperopia (SE ≥  + 3.00 D) were 4.2 and 0.6%, respectively. Astigmatism [cylinder ≥ 1.00 D (≥ 7 years old) and ≥ 1.75 D (≥ 6, < 7 years old)] was found in 31.9%. Conclusions Myopia was the most common refractive error in southernmost province in China (Hainan). Its prevalence increased with age, while hyperopia prevalence showed a decreasing trend. However, myopia, especially high myopia prevalence was much lower than in other urban regions across China.

Abstract Background: Refractive errors and visual impairment in southernmost China have not been reported previously. We aim to investigate and determine the age-specific prevalence of myopia, hyperopia, astigmatism, and visual impairment based on a large population cross-sectional study in Hainan area of southernmost tropical province in China. Methods: A population-based sample of 31,524 children aged 6-15 years from Hainan was assessed. Non-cycloplegic autorefraction and visual acuity (VA) analyses were performed on all participants and a subgroup of participants undergoing cycloplegia. Results: Of all participators, 22.986% presented uncorrected VA (UCVA) decreased worse than 0.3logMAR, 17.206% presented UCVA decreased worse than 0.5logMAR and 46.95% presented abnormal UCVA [worse than 0.1logMAR (≥6, <8 years old) and worse than 0logMAR(≥8years and older)] at least in one eye. The overall prevalence of myopia [spherical equivalent (SE) ≤−0.50 D] and high myopia (SE≤−6.00 D) were 45.97%, 0.96% respectively. Hyperopia [SE ≥+1.00 D (≥7 years old) and SE ≥+2.00 D (≥6, <7 years old)] and significant hyperopia (SE≥+3.00 D) were 4.21% and 0.62%, respectively. Astigmatism [cylinder≥1.00 D (≥7 years old) and ≥+1.75 D (≥6, <7 years old)] was found in 31.87%. Conclusions: Myopia was the most common refractive error in southernmost province in China (Hainan). Its prevalence increased with age, while hyperopia prevalence showed a decreasing trend. However, myopia, especially high myopia prevalence was much lower than in other urban regions across China, as residents of Hainan may benefit from more ultraviolet B (UVB) radiation during daylight exposure.

Background: Many studies have been conducted in the past to study the profile of ocular morbidities in rural areas in different States in India; however such a study was lacking in Goa.Methods: A case series titled, “A clinical profile of ocular morbidities at a Rural Health and Training Centre in Goa”, was conducted between January to March 2018, after Institutional ethical committee approval. The study population included 200 patients residing in households registered under the Rural Health and Training Centre (RHTC) located at Mandur, who attended the Ophthalmology speciality outreach clinic. After informed consent, patients were interviewed based on a pre-tested proforma. Socio-demographic details and history was obtained and a detailed ophthalmic examination was done.Results: 47.5% were between 41-60 years of age, 49.5% used coal, wood or cow dung as fuel; 26.5% were illiterate or had completed primary schooling. 63% had no visual impairment, visual impairment grade 1 and 2 was present in 10% and 19.5% respectively.7.5% were grouped as blind. 55% had refractive errors, 9.5% had corneal opacities, 33% cataract, 4.5% glaucoma, 7% optic atrophy, 7% retinal and macular involvement.Conclusions: 55% of the participants had refractive errors, 9.5% had corneal opacities, 33% had cataract; 33% of whom were illiterates and 30% were those using coal, wood or cow dung as fuel, suggesting lower socio economic background. The high percentage of patients with corneal opacities and cataract was probably due to lower socio economic status, illiteracy and lack of awareness about ocular problems.
