Abstract

A cross sectional study was done to assess the correlation of visual acuity (VA) with integrity of inner segment-outer segment (IS-OS) junction in 80 patients with blunt ocular trauma. HD 5-line raster with enhanced depth imaging was done for each eye at baseline and 1 month after trauma. At the 1 month post trauma, depending on IS-OS junction disruption patients were categorized in 3 groups as no line disruption, disruption <100µ and >100µ.
Mean age of patients was 36.59+16.26 years and 61 were males. Isolated anterior segment involvement with no IS/OS disruption was seen in 51eyes. In 29 patients with posterior segment involvement, 25 had IS/OS junction disruption of which 14 had disruption <100µ and 11 had disruption >100µ. Mean logMAR VA was 0.26 ± 0.30, 0.97 ± 0.16 and 1.06 ± 0.12 in patients of group 1,2 and 3 respectively. IS-OS junction disruption is not an uncommon finding in blunt ocular trauma involving the posterior segment and amount of disruption correlates well with VA.
