Oct in glaucoma; a valuable diagnostic tool

Abstract

Glaucoma is a leading cause of blindness worldwide, and early detection and management are crucial to prevent vision loss. Optical coherence tomography (OCT) is being used these days as an important tool in the repertoire of ophthalmologists. OCT provides high-resolution images of the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and other relevant structures, enabling clinicians to detect subtle changes in these structures before visual field defects become apparent.
