Primary Finding: Pigment Epithelial Detachment (PED)
​The most striking feature in the B-scan is a large, well-defined serous Pigment Epithelial Detachment (PED).
​Appearance: You can see a smooth, dome-shaped elevation of the Retinal Pigment Epithelium (RPE) layer away from the underlying Bruch's membrane.
​Internal Characteristics: The space beneath the RPE is optically empty (hyporeflective/dark), which is classic for serous fluid accumulation.
​Clinical Correlation: The thickness map on the left shows a superior-nasal sector highlighted in red, indicating a massive increase in retinal thickness (788 \mum at the peak on the graph), which corresponds to the height of this PED.
​Associated Findings
​Beyond the PED itself, there are a few other subtle but important details in the scan:
​Subretinal Fluid (SRF): There appears to be a small amount of hyporeflective fluid adjacent to the PED, sitting between the neurosensory retina and the RPE. This suggests an active exudative process.
​RPE Irregularity: To the right of the main PED, the RPE line appears "bumpy" or irregular, which may indicate underlying drusen or chronic changes.
​Vitreomacular Interface: The vitreous appears mostly detached or clear in this section, with no obvious signs of vitreomacular traction (VMT) pulling on the fovea.
​Choroidal Profile: Although the signal strength (QI: 9) is excellent, the choroid beneath the PED shows some "shadowing" or attenuation because the fluid and elevated RPE block the light from reaching deeper structures.
