ABSTRACT
The aim of this study was to establish a correlation between macular thickness on optical coherence tomography [OCT] and 2 visual functions [visual acuity and contrast sensitivity [CS]] in established cases of primary open angle glaucoma [POAG]. A total of 50 consecutive patients of established POAG between 40 years and 70 years of age attending the glaucoma clinic of a tertiary care eye center in North India were enrolled for this cross-sectional study. Best corrected visual acuity [BCVA], CS and macular thickness by spectral-domain-OCT [Cirrus HD-OCT, CarlZeiss, Germany] were evaluated. The groups were compared together by one factor analysis of variance and the significance of mean difference between the groups was done by Newman-Keuls test. Newman-Keuls test revealed a direct relationship of macular thickness to BCVA and CS [P < 0.05]. BCVA and CS are directly related to the macular thickness on OCT.
