Actual (reported)The objective of this study is to compare Cirrus HD-OCT automated measurements of the illumination area under the retinal pigment epithelium (RPE) to expert manual measurements of areas of hypofluorescence typical of geographic atrophy in fundus autofluorescence (FAF) images.

Actual (reported)Difference in mm Squared of Cirrus HD-OCT Automated Measurements of the Illumination Areaa Under the RPE to Expert Manual Measurement of Areas of Hypofluorescence Typical of Geographic Atrophy (GA).
In retinal areas with atrophy, light emitted from the Cirrus penetrates the sclera and choroid which are more reflecting compared with the Retinal Pigment Epithelium (RPE). The areas with higher illumination are associated with areas of Geographic Atrophy (GA), and allow to quantify how big is the area of atrophy. The study will assess the difference between Cirrus HD-OCT measurements of areas of increased illumination under the RPE to hypofluorescence areas on fundus photos as assessed manually by retina specialists.
