This is a developmental abnormality in a 59-year-old man. It is an enclosed ora bay on the temporal side, an isolated island of normal pars plana epithelium. It is important not to confuse this entity with a retinal break. It has smooth, sloping borders not a sharp, thin, visible retinal edge as a retinal break would have. The border looks exactly like that of the ora serrata, and the grayish pigmented base has the same appearance as the normal pars plana.

Condition/keywords: developmental abnormality, enclosed ora bay, grayish pigmented base, horizontal nasal meridian, pars plana epithelium, smooth sloping borders, temporal retina

This large reddish area in the nasal periphery of this left eye is actually an enclosed ora bay. For other examples of this, see slide pair 5 and 6. This developmental abnormality could easily be confused with a retinal break. A very unusual feature of this photograph is the presence of a tiny true retinal break at the far right end of the enclosed ora bay and lying just to the left of the yellow zone in the middle of the photograph
