Visual Acuity Outcomes. A At final follow-up of the 188 eyes, 30% of eyes had LogMAR VA ≤ 0.9 (BCVA better than 20/200) and 6% had LogMAR VA ≤ 0.4 (BCVA 20/50 or better). Fifty-seven percent of eyes had LogMAR VA ≥ 1.0 (BCVA 20/200 or worse) with 9% unable to detect light. Thirteen percent of patients were too young to cooperate with optotype testing. B Analysis of the better seeing eye showed that 50% of the patients met the legal definition of blindness with LogMAR VA ≥ 1.0 (20/200 or worse) at final follow-up. One percent of patients were not able to detect light with either eye. Thirty-eight percent of patients had LogMAR VA ≤ 0.9 (better than 20/200) and 9% of patients had LogMAR VA ≤ 0.4 (20/50 or better). C In the 133 of 188 eyes that were able to complete optotype visual acuity testing at both initial and final visits, 34% of eyes showed stable VA (< 0.1 change in LogMAR VA) and 16% of eyes had an improvement in VA. Twenty-one percent of eyes showed worse LogMAR VA at final follow-up. Twenty-nine percent of patients lacked optotypte testing at either presentation or final follow-up. D Analysis of the better seeing eye showed that 35% of patients had stable VA (< 0.1 change in LogMAR VA) at initial and final follow-up. Seventeen percent of patients had improved LogMAR VA while 19% had worse VA at final follow-up compared to presentation
