title: Secondary retinal detachment interpreted as a part of uveal melanoma by CT-scan.
abstract: Four patients with histologically verified uveal melanomas were examined with computed tomography (CT) scan. Ophthalmoscopy revealed a sharply deliminated tumour surrounded by a secondary retinal detachment. The clinically calculated size of the tumours corresponded well with the histological specimens. The CT-scan indicated a greater size of the tumours. The discrepancies were due to difficulties in differentiation between the tumour tissue and the subretinal fluid which have almost identical CT-numbers. By combining axial and coronal views it was possible to distinguish the tumour from the secondary retinal detachment.
