Abstract

In this retrospective study, patients who underwent Perimetry testing(Octopus 600) and OCT RNFL thickness analysis(Optopol Revo60) were included. The primary outcome was to see the correlation between thickness the 10 OCT RNFL sectors and the Visual Field mean deviation in the corresponding 10 sectors of Cluster Analysis. Using logistic regression, the probability of each OCT RNFL sector to predict a corresponding field defect along with the ability of the OCT RNFL thickness to predict presence or absence of Glaucoma was determined. In 100 eyes of 62 patients, out of the 10 OCT RNFL-sectors analyzed, 4 sectors showed a significant correlation with their corresponding visual field cluster defects. The above 4 RNFL sectors were also able to predict significant field defect in their corresponding Perimetry clusters. The remaining 6 OCT RNFL sectors showed no significant correlation with visual fields. Conclusions: RNFL analysis on the Revo60 OCT correlates well with Octopus Perimetry.
