Abstract

To evaluate the predictability of visual outcome in vaculopathy patients after treatment, we compared the difference between the pre-treatment visual acuity measured by hand-held laser interferometer and the posttreatment corrected visual acuity using Han`s visual acuity chart. Disease distribution was as follows; BRVO(18 cases), CRVO(11 cases), CSCR(9 cases), posterior uveitis(4 cases). The mean up period was 3.45 months. Among 42 cases, 28 eyes showed positive disparity and 13 eyes showed negative disparity. The range of disparity was from -0.2 to +0.3(mean 0.113). The post-treatment visual acuity was predictable within 2 lines in 38 eyes(90%) We concluded that the hand-held laser interferometer is one of the reliable methods to predict the post-treatment visual acuity in maculopathy patients.
