[Colobomatous fossette of the optic papilla and juxtapapillary choroidal malignant melanoma].

The paper presents a clinical case of colobomatous fossette of the optic nerve papilla complicated with macular decolation, in association with the malignant melanoma of the choroid. Some aspects of the pathogeny of the retinal decoloration are discussed in this context. Some possible corrections between the two border retinal decolorations--the serous interpapillary macular decoloration and the retinal decoloration secondary to the melanoma of the choroid--are also proposed.
