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 1 092 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±3.29 years. 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(22.50%)and myopia(7.50%). Compliance with spectacle wear combined with occlusion therapy and active vision therapy was 73.30%(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.
