Diagnostic tests, with an optical coherence tomography (OCT) we can look closely at the retina and obtain a virtual, non-invasive biopsy. Similar to a CAT scan, the OCT uses infrared light rather than x-rays to form a cross-sectional view of your retina. This detailed image of the retina allows your doctor to see the retina at a microscopic level and detect swelling in the retina The photobleaching of Spectralis OCT may represent an interpretational bias in participants undergoing FAF in light-adapted conditions after acquisition of OCT images for different macular diseases. The acknowledgment that at least some eyes present such effects may restrict erroneous interpretation of FAF examinations

Swept-source OCT (SS-OCT; DRI-OCT, Topcon Japan) is the latest milestone in retinal and choroidal imaging. To overcome scattering by the RPE, which disabled visualization of deeper lying structures, a longer wavelength was adopted for this machine (1050 nm vs 840 nm in SD-OCT), and photodetectors instead of CCD cameras led to a further increase. and controls underwent macular, choroid, and peripapillary nerve ber layer thickness analysis with Spectralis domain OCT (Spectralis OCT Heidelberg Engineering, Dossenheim, Germany).
