    Abstract:
    PURPOSE: To determine the causes of visual impairment and blindness amongst children in schools for the blind in Myanmar; to identify the avoidable causes of visual impairment and blindness; and to provide spectacles, low vision aids, orientation and mobility training and ophthalmic treatment where indicated. METHODS: Two hundred and eight children under 16 years of age from all 7 schools for the blind in Myanmar were examined and the data entered into the World Health Organization Prevention of Blindness Examination Record for Childhood Blindness (WHO/PBL ERCB). RESULTS: One hundred and ninety nine children (95.7%) were blind (BL = Visual Acuity [VA] < 3/60 in the better eye) and 3 had severe visual impairment (SVI = VA < 6/60 to 3/60 in the better eye). Most children had corneal abnormalities as the major anatomical site of SVI/BL (100, 49.5%), however the cause of SVI/BL was unknown in the majority (88, 43.6%). Measles keratitis was the commonest identifiable cause (17.4%) and 88 children had avoidable causes of SVI/BL (43.6%). Nearly 16% of children required an optical device and 24.2% required medical attention, with a potential for visual improvement through intervention in 15.8%. CONCLUSION: Nearly half of the children in schools for the blind in Myanmar had potentially avoidable causes of SVI/BL. With measles being both the commonest identifiable and commonest avoidable cause, the data supports the need for a measles immunization campaign. There is also a need for a dedicated pediatric eye care center with regular ophthalmology visits to the schools, and improved optometric, low vision and orientation and mobility services in Myanmar.
