What is a characteristic feature of Fibrovascular PEDs on imaging?

Fibrovascular pigment epithelial detachments (PEDs) are associated with choroidal neovascularization (CNV), which is a key feature in their identification on imaging. The presence of choroidal neovascularization is indicative of an underlying pathophysiological process involving abnormal growth of blood vessels from the choroid layer of the eye, leading to the formation of the PED. On imaging, this characteristic helps distinguish fibrovascular PEDs from other types of PEDs and drusen, which do not typically involve neovascularization.

In the context of imaging, fibrovascular PEDs will often present with features such as fluid accumulation, hemorrhage, or exudates, all of which can be attributed to the presence of these abnormal vessels. Recognizing the association with CNV is crucial for diagnosing and managing conditions such as age-related macular degeneration, where these features often correlate with the severity of the disease and influence treatment options.
