An optical coherence tomography (OCT) of the retina, showing a Fuchs spot The Fuchs spot (also known as Förster-Fuchs' Spot [ 1 ] ) is a degeneration of the macula in cases of high myopia . It is named after the two persons who first described it: Ernst Fuchs , who described a pigmented lesion in 1901, and Forster , who described subretinal ...
A high-resolution spectral-domain OCT scan (3×3 mm) of a dry age-related macular degeneration eye showing geographic atrophy and drusen in macula on both cross-sectional and en face fly-through. Optical coherence tomography ( OCT ) is a high-resolution imaging technique with most of its applications in medicine and biology.
Fundus photographs are also used to document abnormalities of disease process affecting the eye, and/or to follow up on the progress of the eye condition/disease such as diabetes, age-macular degeneration (AMD), glaucoma, multiple sclerosis, and neoplasm of the choroid, cranial nerves, retinal or eyeball.
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before. [4]
[18] [19] This has allowed OCTA to obtain detailed images of retinal vasculature in the human retina [20] and become widely used clinically to diagnose a variety of eye diseases, such as age related macular degeneration (AMD), [21] diabetic retinopathy (DR), [22] [23] artery and vein occlusions, and glaucoma.

There are different targets a patient can fixate on during the test. They are chosen on the basis of the patient's conditions. [12] Central target: Yellow light in the bowl's centre; Small diamond: For patients who cannot see the central target such as those with macular degeneration. The patient looks into the centre of the four lights

The incidence of age-related macular degeneration and its associated features increases with age and is low in people <55 years of age. [101] Smoking is the strongest modifiable risk factor. [102] As of 2008, age-related macular degeneration accounts for more than 54% of all vision loss in the white population in the US. [103]
