164. An elevated retina and a dark spot on the nerve

A 25-year-old presents with blurred vision. Why?

Tip #164


There is clear elevation of the retina from the underlying RPE, as subretinal fluid (SRF) is elevating the ellipsoid zone from the RPE. There is significant intraretinal fluid (IRF). A reverse shadow is also seen.

The patient was noted to have a dark lesion on the disc (video) and was diagnosed with an optic pit.
