In order to obtain findings in early-stage glaucoma, we measured the thickness of retinal nerve fiber layer using a Nerve Fiber Analyzer GDxTM. The cases comprised 50 eyes of 38 patients with early-stage glaucoma with impaired visual field, 22 eyes of 16 patients with glaucoma with advanced visual field defect and 20 eyes of 11 age-matched healthy persons as control. Out of 15 parameters, eyes with advanced glaucoma showed significantly abnormal values in 12 parameters as compared with control. Abnormal value (p<0.05) in more than one parameter was detected in 82% of eyes with early-stage glaucoma, of which only 2 parameters were significant as compared with the control, namely, deviation from normal in the inferior quadrant and inferior average. The specificity and sensitivity for all the glaucoma eyes were 80% and 78% respectively. The sensitivity for early-stage glaucoma was 72%. These findings show that the current method is not adequate in detecting early-stage glauoma.
