Understanding White Spots in the Eye: Causes and Implications

DESCRIPTION

This article explores the phenomenon of white spots observed in the retina, choroid, and optic disc. It discusses the normal anatomical structures of the eye, such as the sclera, and explains how conditions like retinal scarring or RPE loss may reveal the sclera. We also examine the scleral crescent, its appearance around the optic disc, and related pigmentation. Understanding these white structures can help in identifying underlying eye conditions and ensuring timely diagnosis and treatment.

  1. What is White? Normal white structures What would cause a white spot in the retina, choroid or optic disc--what is white? The only inherently "white" element in the normal eye is the sclera. When there is scarring of the retina and/or loss of RPE, the sclera can be seen. Although we are labeling spots as "white"-some have a distinctly yellow appearance (such as hard exudates).

  2. What is White? Scleral Crescent The scleral crescent is seen around the disc. The choroid and retina just don't make it to the edge of the disc (see discussion chapter 2). This "white" is usually around the central aspect of the disc. It may also have pigment associated with the crescent. An extensive myopic scleral crescent almost around each disc. The arrows outline the scleral crescent and the arrow head is at the edge of the disc.
