Which subtype of PED is known for its hemorrhagic features?

Fibrovascular PED, or pigment epithelial detachment, is characterized by its association with choroidal neovascularization (CNV), which can lead to bleeding. These hemorrhagic features are primarily due to the presence of new, abnormal blood vessels that can rupture and bleed into the detachment or underlying retinal tissue.

Fibrovascular PEDs often occur in conditions such as neovascular age-related macular degeneration (AMD), where abnormal blood vessels develop underneath the retinal pigment epithelium (RPE). The vascular component is what distinguishes this type from other subtypes, as they inherently possess a more substantial risk for hemorrhage due to their fibrous and vascular nature.

In contrast, serous PEDs are typically more fluid-filled without significant vascular components, while drusenoid PEDs are linked primarily to drusen and do not exhibit hemorrhagic tendencies. Congenital PEDs are usually associated with developmental anomalies rather than the neovascularization found in fibrovascular variants. Thus, the hemorrhagic features seen in fibrovascular PEDs make it the most likely candidate in this scenario.
