[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.

Combined keratoplasty and cataract extraction.

A short film showing our technique of combined penetrating keratoplasty and intracapsular cataract extraction was shown, and the postoperative results in 72 eyes after an average of 3 years were reported.

[A contribution on the clinical pictures, fluorescence angiography and histology oe essential progressive iris atrophy (author's transl)].

The clinical and irisangiographical findings of 2 patients with essential progressive iris atrophy of the juvenile are reported. Histopathological examination was possible in one case. The differential diagnosis including to iridoschisis, Chandler's syndrome, Cogan-Reese (iris-naevus) syndrome is discussed. The aetiology of this rare disease remains obscure. Most authors believe that the iris stroma changes and pigment epithelial atrophy result from a vascular deficiency. Iris angiographical findings confirm this belief. The prognosis is poor, due to the therapy resistant secondary glaucoma. Surgery of the ciliary body appears to be the only possible procedure.

[The clinical picture, fluorescence angiography and histologie of a ringmelanoma of the iris (author's transl)].

Report on a rare case of an iris-ringmelanoma. Arising from the iris base the primary tumor spread in a continuous line along the anterior chamber angle and a shedding of tumor cells in other places of the iris surface could be stated as well. A unilateral dark spotted colouring of the iris with a secondary glaucoma was clinically observed. Gonioscopy, diaphanoscopy, 32P-test, and iris fluorescence-angiography aided the diagnosis. Fluorescence angiography appears to be of particular value in the diagnosis of malignant melanoma of the iris: The peculiar filling pattern seen at the pupillary border of the tumor has up to now only been found in malignant processes of the anterior uvea. The clinical tentative diagnosis of malignant ringmelanoma of the iris, could histopathologically be verified.

[Excision of the ciliary-body in cases of secondary closed-angle glaucoma (author's transl)].

Six cases are reported, in which an excision of the ciliary-body has been performed: 5 cases with secondary closed-angle glaucoma, and one case with secondary open-angle glaucoma. All eyes were aphakic, and in all cases other surgical interventions preceded. The ciliary-body excision is the easiest exactly doseable procedure, compared with other procedures regarding the ciliary-body. Usually excision of the ciliary-body represents the last choice to offer, however in selected cases it might be the method of choice. In this aspect our results are encouraging. The technical details of this procedure are described.
