Multimodal assessment of microscopic morphology and retinal function in patients with geographic atrophy
Purpose: To correlate retinal function and visual sensitivity with retinal morphology revealed by ultrahigh-resolution imaging with adaptive optics -optical coherence tomography (AO-OCT), on patients with geographic atrophy. Methods: Five eyes from five subjects were tested [4 with geographic atrophy (66.3 ± 6.4 years, mean±1S.D.) and 1 normal (61 years)]. Photopic and scotopic multifocal electroretinograms (mfERGs) were recorded. Visual fields were assessed with microperimetry (mP) combined with a scanning laser ophthalmoscope for high-resolution confocal retinal fundus imaging. The eye tracker of the microperimeter identified the preferred retinal locus that was then used as a reference for precise targeting ...
