Surgical Treatment of Pigmented Tumours of the Iris and the Iridociliary Area

The authors present a group of six patients with pigmented tumours of the irisand the iridocorneal angle where they performed excision of the tumour byiridectomy (3 patients) or iridiocycletomyy (3 patients). In all six patients witha pigmented tumour of the iris an impaired blood-ocular fluid barrier was foundand colouration of the tumour mass by fluorescein. In one patient a heavilypigmented tumour was detected which masked the vascular network.Impairedpermeability was found more markedly at the margins. Histological examinationconfirmed in five instances melanoma of the iris, in one instance a pigmentednaevus was involved. During the mean observation period of 32.5 months none ofthe patients developed a relapse or metastases. Consistent with the extent of thesurgical intervention, within 6 months at the latest in all patients the disorder ofthe blood-ocular fluid barrier improved.
