The correlation between visual field defects and focal nerve fiber layer thickness measured with optical coherence tomography in the evaluation of glaucoma.

Purpose: To study the correlation between known visual field defects and retinal nerve fiber layer (RNFL) thickness detected by optical coherence tomography (OCT) in glaucomatous eyes.

Materials And Methods: Visual field parameters and OCT RNFL measurements of 28 eyes of 28 glaucoma patients with various stages of glaucoma were compared with 38 eyes of 38 normal age-matched controls. A perimetric nerve fiber bundle map was built by dividing the visual field area into 21 zones.
