OCT in nevus testing can reveal which of the following?

• A. Drusen and RPE alterations
• B. Vascular occlusion
• C. Retinal detachment
• D. Glaucoma

Answer: (A)

Focusing OCT imaging on the outer retina and RPE helps evaluate a choroidal nevus for characteristic surface changes. Drusen and alterations in the retinal pigment epithelium are the findings OCT can reveal in this setting. Drusen appear as small elevations or deposits at the RPE level with distinct reflectivity on the scan, and RPE alterations show up as irregular RPE contour or disruption over the nevus. These features are useful for baseline documentation and monitoring. Vascular occlusion, retinal detachment, or glaucoma each produce different patterns on OCT that are not the typical findings used to characterize a nevus, so they’re not the primary features looked for in this context.
