Abstract

Background and Objective: To compare the anatomy of different retinal layers adjacent to areas of geographic atrophy (GA) to those of eyes with no known ocular diseases. Patients and Methods: Spectral-domain optical coherence tomography (SD-OCT) scans from eyes with GA were retrospectively reviewed. Two scans with no findings suggestive of GA changes on OCT were selected from immediately above and/or below the edge of the lesions. Thickness values of the retinal layers were calculated and compared to values obtained from normal subjects. Results: Forty-four eyes (30 patients) were compared to 20 healthy eyes. Retinal pigment epithelium (RPE), inner nuclear layer (INL), and full retinal thickness (FRT) values were significantly lower in patients compared to healthy subjects. Thicknesses of all other layers were not significantly different. Conclusion: Clinically appearing, non-involved RPE and INL layers of eyes with GA demonstrate significant thinning compared to corresponding layers in eyes with no known ocular diseases.
