A primary cause of decreased vision was determined for each child. The prevalence of FLV was calculated for children 6-14 years old. Spectacles and low vision devices were provided free of charge.

Results

345 children aged 6-14 years were referred and 231 had FLV. The positive-predictive value of KI referrals was 64.5%. The prevalence of FLV was 0
