Optical coherence tomography in measuring retinal nerve fiber layer thickness sin normal subjects and patients with open-angle glaucoma

摘要

Objectives To investigate image characteristics and thickness of the retinal nerve fiber layer (RNFL) in normal and glaucomatous eyes using optical coherence tomography (COT), an analyze the relationship between RNFL tickness and visual field index. Methods Eighty-three normal persons (150 eyes) and 83 patients with primary open angle glaucoma (POAG, 149 eyes) underwent OCT examinations with 3.4 mm diameter circle scan to calculate the RNFL thickness. Statistical analysis was used to compare differences in RNFL thickness sin quadrants and means between the normal and glaucomatous groups and the different stages of POAG.
