**17. Early start with high visual acuity**

Initiation of treatment in high-risk eyes with BCVA better than 20/40 (Decimal 0.5, LogMAR 0.3) has resulted in better response and higher visual outcome in short- and long term. In our cohort of 152 eyes, 82.89% had BCVA 20/40 at their final visit after 3 to 8 years of management. Out of 126 eyes with BCVA 20/40 and better prior to treatment, 76.96% retained it through the follow up, however only 34.63% of the eyes with BCVA 20/50 and less could improve to 20/40 and better. Final BCVA 20/150 and less (the level of legal blindness in Kuwait) was seen in 4.82% of the eyes with high initial visual acuity and in 23.06% in the eyes with worse baseline vision.
