AMD is diagnosed by stereoscopic biomicroscopy and additional examinations of the macula, such as fluorescein angiography (FA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT). The patient's visual status can be monitored with the Snellen chart and Early Treatment Diabetic Retinopathy Study (ETDRS) chart, the Snellen chart being most often used in Greece.
