Brief summary

Compare the image quality of the fundus autofluorescence and fluorescein angiography

Detailed description

The objectives of this study are to: 1. Compare the image quality of the fundus autofluorescence (FAF) photographs between DRI OCT Triton (plus) and TRC-50DX retinal camera. 2. Compare the image quality of the fluorescein angiography (FA) photographs between DRI OCT Triton (plus) and TRC-50DX retinal camera.
