We evaluated 51 eyes regarding glaucomatous visual field loss and retinal nerve fiber layer thickness (RNFL) as measured by optical coherence tomography(OCT). The series comprised 4 eyes of ocular hypertension and 47 glaucoma eyes. Each eye was scanned circularly around the optic disc and was tested by kinetic and static perimetry. Eyes in the early stage of visual field loss by the Kosaki Classification showed no difference in the mean RNFL thickness. Eyes in the middle stages showed significant reduction in the thickness. The RNFL thickness decreased along with the grading by the Aulhorn Classification. The mean deviation (mean defect) by static perimetry was significantly correlated with the RNFL thickness (r= 0.73 (similar)0.88, p<0.0001). The findings show that OCT is of value as adjunct to blue-on-yellow perimetry and white-on-white perimetry using size I stimulus in the diagnosis of early glaucomatous visual field defects.
