Abstract

The diagnosis of malignant melanoma of the choroid may occasionally be difficult in eyes with small sized tumor, extensive retinal detachment or opaque media. We experienced two cases of malignant melanoma of the choroid misdiagnosed as a retinal detachment. Since the first case of choroidal melanoma was hidden under a balloon of subretinal fluid, it had been mistakenly operated on two times to repair a rhegmatogenous retinal detachment at other hospital. In this case, drainage of subretinal fluid could potentially cause the spread of tumor cells to adjacent structures. The second case also was referred to our hospital under the diagnosis of retinal detachment at local clinic. In both cases an accurate diagnosis was made by indirect ophthalmoscopy, fluorescein angiography, ultrasonography, and computerized tomography of the orbit. Enucleations were performed carefully in both cases.
