Three basic types of foveal involvement in choroidal melanomas.
Three cases are used to demonstrate the main types of cystoid macular edema, which have been seen to occur in association with choroidal melanomas: 1) direct involvement in cases, where the neoplasm is located under the foveal retina, 2) indirect involvement due to a subfoveal exudate in choroidal melanomas distant to the fovea and 3) indirect foveolar involvement without associated subfoveal tumor or exudate. A recording of the pathology of these three basic reaction patterns of the central retina in choroidal melanomas is considered important. It is emphasized, that combinations of the reactions are common and may result in more complex situations.
