TABLE 515 Light Colored Spots in the Fundi


Cotton-Wool Patches (Soft Exudates)

Cotton-wool patches are white or grayish, ovoid lesions with irregular (thus "soft") borders. They are moderate in size but usually smaller than the disc. They result from infarcted nerve fibers and are seen with hypertension and many other conditions.

Drusen Very Bright


Drusen are yellowish round spots that vary from tiny to small. The edges may hard, as here, or soft. They are haphazardly distributed but may concentrate at the posterior pole. Drusen appear with normal aging but may also accompany various conditions, including age-related macular degeneration.

Hard Exudates

Hard exudates are creamy or yellowish, often bright lesions with well-defined (thus "hard") borders. They are small and round (as shown in the lower group of exudates) but may coalesce into larger irregular spots (as shown in the upper group). They often occur in clusters or in circular, linear, or star-shaped patterns. Causes include diabetes and hypertension.

Chorioretinitis Toxoplasmosis

Healed Chorioretinitis

Here inflammation has destroyed the superficial tissues to reveal a well-defined, irregular patch of white sclera marked with dark pigment. Size varies from small to very large. Toxoplasmosis is illustrated. Multiple, small, somewhat similar-looking areas may be due to laser treatments. Here there is also a temporal scar near the macula.
