Abstract

Purpose: : To determine the usefulness of optical coherent tomography (OCT) for quantitative and qualitative analyzes of eyes with geographic atrophy due to age related macular degeneration (AMD).

Methods: : Retrospective case series. Retinal OCT (Stratus OCT 3, images of eyes with geographic atrophy secondary to AMD were reviewed. The 6–mm fast macular thickness maps centered at the fovea were used.

Results: : Six eyes of four patients (2 males, 2 females; 3 caucasian origin, 1 hispanic origin; mean age 76 ranging from 60 to 85 years) were examined with OCT. The average thickness of neurosensory retina was 202 ± 49 µm. The patient with the worst best corrected visual acuity (BCVA) had the smallest retinal thickness at the fovea – 165 ± 40 µm. Patients with BCVA of 20/100 (LogMAR – 0.7) or better had an average thickness of 240±17µm.

Conclusions: : OCT can be used to follow the clinical progression of geographic atrophy and findings can be correlated with BCVA.
