Follow up of suspected choroidal naevi

The correct diagnosis of small pigmented choroidal tumours is often difficult. We reviewed 16 cases with a mean follow-up of 58 months and illustrate the difficulties which can be encountered in correctly diagnosing small to medium-sized pigmented tumours. Of those 16 cases, 4 cases ultimately progressed and needed appropriate therapy. Some suspected melanomas grew initially but then stayed stationary for a long period of time. In doubtful cases, it is essential to document the evolution with echography, fundoscopy, fundus photographs, fluorescein-angiography, visual fields and eventually ICG-angiography. If progression is documented, appropriate treatment has to be considered.
