Optical Coherence Tomography Assessment of Apparent Foveal Swelling in Patients with Foveal Sparing Secondary to Geographic Atrophy
Objective:
To determine whether foveal swelling exists in patients with foveal sparing and geographic atrophy (GA) secondary to dry age-related macular degeneration (AMD) and to establish the contribution of different foveal layers to this condition by use of spectral-domain optical coherence tomography (SD-OCT).
Design:
Prospective comparative case series.
Participants:
We assessed patients from a longitudinal study with foveal sparing and GA secondary to AMD. Of an initial sample of 108 patients, 13 eyes of 10 patients complied with the inclusion criteria to study eyes in which apparent swelling would not (Read more...)
