“…The prognosis for the patient with a melanoma of the choroid or ciliary body is largely dependent on the type of cell of which the turnout is composed, but also on the extent of epi-and extrascleral invasion (Shammas and Blodi, 1977;Affeldt et al, 1980;Oosterhuis and de Wolff-Rouendaal, 1981).…”

“…In ophthalmology the high resolution CT-scan is being used more and more. Ophthalmological examination, especially by means of funduscopy, fluorescein angiography and perimetry, gives a good picture of an intraocular turnout (Oosterhuis and de Wolff-Rouendaal, 1981). Ultrasonography adds information about the prominence and the shape and gives information about the tissue structure (Till and Hauff, 1981).…”

Twenty-two patients, who were suspected of an intraocular tumour, were examined with the high resolution thin slice CT-scan (1.5 or 3 mm slices). The final diagnosis in 14 cases was an uveal melanoma, and in 3 cases in which an uveal melanoma was suspected a chorioretinal haemorrhage, an exudative macular degeneration type Junius Kuhnt and an intrascleral foreign body were respectively found. In 2 cases intraocular metastases were demonstrated, and in 2 other cases malignant lymphomata. One patient had a haemangioma. In 10 of the 14 patients with uveal melanomata enucleation was performed and 4 were treated by ruthenium application. The CT-scan was compared with ultrasonographic, operative and histological findings. From the study it appears that the CT-scan is useful for screening uveal melanomas. It is however difficult to distinguish the uveal melanoma from a secondary retinal detachment; differentiation from an exudative macular degeneration was not possible. The size of the tumour was only represented correctly on the CT-scan in half the cases. CT examination fails to demonstrate or exclude epi- and extrascleral growth. The multiple metastases and the haemangioma could only be seen with difficulty on the CT-scan; the latter was however clearly visible after the injection of contrast. The foreign body could be clearly seen without contrast.

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.
