ABSTRACT
The authors analyze six cases with malignant melanoma of the conjunctiva treated at the Ophthalmological Clinic in Brno in 1967-1988. They evaluate contemporary therapeutic possibilities and results of treatment. The prognosis of the condition is in general more favourable than in malignant melanomas of other mucous membranes.

The authors describe two cases of siderosis of the bulbus which developed as a consequence of late diagnosis of intraocular foreign bodies. The character of siderosis differed, however, in the two patients. In the first patient the picture of generalized siderosis confirmed also by electroretinographic examination permitted the assumption of an adverse course of the disease already on admission, as was confirmed by the progression of the disease even after removal of the intraocular foreign body. In the second patient probable encapsulation of the foreign body led to focal siderosis and a favourable course of the disease.

A pigmented lesion of the iris followed up for five years in a 31-year-old female patient with marked progress during the past two years which led to block excision of the formation. Clinical signs (growth, vascularization, pigmentation and blood in the angle) as well as results of auxiliary examinations (ultrasound, fluorescein angiography) suggested a malignant lesion. However, histological examination provided evidence of the benign nature of the formation. Contemporary diagnostic non-invasive methods cannot decide definitely on the nature of a progressing neoplasm of the iris. The authors recommend long-term patient observation of these patients and surgery only in fully indicated cases.

The authors investigated physical and chemical properties of fluorescein, a substance widely used in ophthalmology. In view of the increased application of fluorescein angiography in the diabetological programme, the authors draw attention to possible undesirable effects of fluorescein and submit an account of complications recorded after application of this substance to 576 patients examined by this method at the Ophthalmological Clinic in Brno.
