OCT is considered a useful noninvasive adjunct for detecting retinal and subretinal pathology secondary to CNV. It can identify RPE detachments, subretinal and intraretinal fluid, soft drusen, CNV, and cystoid macular edema, as well as assess the integrity of the photoreceptor and RPE layers.
OCT angiography is a newer noninvasive technology that has been used to diagnose and classify CNV membranes without the need for intravenous dye. Although FA is considered the gold standard for wet AMD diagnosis, OCT has gained popularity both for the detection of wet AMD and the monitoring of treatment response.
