[Fluorescencangiographical and histopathological findings in cases of non-pigmentes iris cysts (author's transl)].

The clinical, fluorescencangiographical and histopathological findings in 3 cases of non-pigmented iris cysts are described. The first case was a posttraumatic cyst after cataractextraction, the second in all probability, also a posttraumatic cyst and the third case was a spontaneous intrastromal nonpigmented iris cyst. Although the clinical and histopathological findings are not always helpful in the differential diagnosis between non-pigmented posttraumatic and non-pigmented spontaneous iris cysts, we believe, that fluorescencangiography may provide valuable additional information. The preoperative differentiation is important, because radical excision including the affected cornea or sclera is necessary in the posttraumatic cases, whereas only a simple iridectomy is required for the spontaneous cysts.
