We measured the thickness of retinal nerve fiber layer (RNFL) around the optic disc in 37 eyes using an optical coherence tomography (OCT3). The series comprised 29 normal eyes and 44 glaucomatous eyes. All the eyes had visual acuity of 0.9 or over. The RNFL thickness in normal eyes averaged 106 μm. It was thinner in the temporal and nasal quadrants and was thicker in suprior and inferior quadrants. There were no difference in RNFL thickness among stages of glaucomatous visual field defect as classified by Aulhorn and modified by Greve. Significant difference in RNFL thickness was present only between normal eyes and stage I glaucoma (p<0.01). The MD value by Humphrey perimetry decreased along with progression of stage of glaucoma. The RNFL thickness was positively correlated with the MD value and stage of glaucoma (r=0.74, p<0.001). LA: Japanese
