Abstract |
PURPOSE We investigated the correlation of automatic visual field test and Retinal Nerve Fiber (RNFL) thickness measured by OCT and examined the presence of RNFL thickness decrease in the apparently normal hemifield in glaucomatous eyes. METHODS: 52 Normal subjects and 41 glaucomatous eyes were included. Statistical correlation between the sum of total deviation in 37 stimulus of each hemifield and RNFL thickness decrease rate was evaluated. Statistical dfference between the RNFL thickness of the apparently normal hemifield in glaucomatous eyes and the RNFL thickness of corresponding hemifield in normal subjects was also evaluated. RESULTS: There was statistically significant correlation of Total deviation (TD) sum and RNFL thickness decrease rate (p<0.01). There was no significant decrease of RNFL thickness in the apparently normal hemifield (p>0.1). CONCLUSION: RNFL thickness measured by OCT showed significant correlation with sum of TD of automatic visual field test. There was no decrease of RNFL thickness in the apparently normal hemifield in glaucomatous eyes. |
