Chorioretinal scars

Chorioretinal scars are tiny scars, anywhere from a half millimeter to one or two millimeters in size in the back of the eye. These areas may have components of "fibrosis" (scarring), "atrophy" (thinning of the retinal layers), and "pigment hyperplasia" (pigmentation or darkening of the scar).

These tiny scars in the back of the eye are quite common. In most cases they are not significant and do not affect vision, but it is important to document the presence, size, and location of a chorioretinal scar. The scars do not have any malignant potential. Rarely, the scars may represent prior infections with toxoplasmosis or toxocara. In the case of toxoplasma scars, patient may develop a re-activated infection which may need treatment.
