STATUS OF OPTIC NERVE HEAD CONFIGURATION AND MEASUREMENT RETINAL NERVE FIBER LAYER THICKNESS IN PRIMARY OPEN ANGLE GLAUCOMA

Abstract

The purpose of study is to evaluate the diagnostic ability of retinal nerve fiber layer (RNFL) thickness parameters from Stratus optical coherence tomography (OCT) to discriminate between healthy eyes, the eyes with glaucoma and also between different stages of glaucoma. OCT measurements of RNFL thickness may provide clinically important information in staging the glaucomatous damage. OCT contributes to the identification of local defects in the RNFL of patients. The clock hour location of localized RNFL defects around optic disc did not affect significantly the sensitivity of Stratus OCT for superotemporal RNFL defects may be due to their smaller angular width compared with that of inferotemporal RNFL defects. The direct correlation was found between OCT measurements of retinal nerve fiber layer and the stage of glaucoma. These measurements will provide clinically relevant information in monitoring glaucomatous changes during follow-up.
