[Molteno/von Denffer drainage implants in therapy-refractory glaucomas].

BACKGROUND: In glaucoma eyes in which the pressure regulation was not possible with drugs and surgery or which were blind already, we treated the patients with a Molteno implant by von Denffer. MATERIALS AND METHODS: In 10 years (1995 to 2004) we treated 19 eyes with a glaucoma drainage device -- the Molteno implant developed by von Denffer. The average age of the patients was 64 (range: 15 to 77) years. On average 3,1 operations were realised before the implant. The average eye pressure was 44 mm Hg preoperatively. Our patients suffered from different glaucomatous diseases: 7 primary glaucomas (congenital, open and narrow angle glaucoma) and secondary: neovascular glaucoma (4), PEX glaucoma (2), traumatic glaucoma (3) and postoperative glaucoma (3). RESULTS: The intraocular pressure had a successful outcome of under 20 mm Hg in 13 eyes, 5 patients out of these were treated with 1 to 3 drugs. Early complications (flat anterior chamber, hyphaema, hypotonia) were reversible. Late complications were phthisis bulbi (3), explantation of the implant (2) and one evisceration bulbi. We found an improvement of the visual acuity in 4 cases in traumatic and postoperative glaucoma. The stabilisation of visual acuity was possible in primary glaucoma. CONCLUSIONS: The implantation of the Molteno implant by von Denffer is an ultimate ratio in eyes with persistent high intraocular pressure. A durable reduction of the pressure is possible in two-thirds and the conservation of the bulbus was achieved in three-fourths of the patients.

[Carl Gustav Carus (1789-1869) and his single ophthalmologic publication].

Carl Gustav Carus is the most important personality in medicine in Dresden in the first half of the 19th century. He is well known for his manifold activity as a doctor, scientist and philosopher as well as a landscape painter of the romantic period. His literary output is estimated at about 25,000 printed pages. There is just one paper which touches ophthalmology and teratology: in 1842, Carus described the monstrous head of a pig with cyclopia. The discussion follows an idealistic line with comparative anatomical studies in fauna and flora.

[Carl Ferdinand von Graefe (1787-1840) and his relevance to ophthalmology].

This paper gives a short biography of Carl Ferdinand von Graefe, father of the most famous German oculist Albrecht von Graefe (1828-1870). On the occasion of his 200th birthday his work, in particular in the field of ophthalmology (cataract operations, prescription formulae, and therapeutic procedures, publications) is given due recognition. Although C.F. von Graefe was first and foremost a surgeon and the creator of plastic surgery of the face, he may also be considered one of the pioneers of ophthalmology, which, in the first third of the last century, had not yet achieved the status of an independent specialty.

[Primary isolated amyloidosis--a rare corneal degeneration].

Report on a 47-year-old woman patient in whom an eccentric tumorlike corneal change was found in the left eye. Only after penetrating keratoplasty was the exact diagnosis--a primary isolated corneal amyloidosis--established, by light microscopic examination. The graft remained clear. Familial and systemic amyloidosis were ruled out by further examinations. The prognosis is favorable.

[Histopathologic study following optic keratoprosthesis. A case report].

The authors present the case history of a patient in whom an optical keratoprosthesis was implanted after recurrent corneal ulcers in aphakia at the age of 80. The globe was examined histologically post mortem. A solid retroprosthetic membrane, a hemorrhage in the vitreous and retinal detachment after trauma were found to be the causes of the visual disorder. Wound healing following implantation of a keratoprosthesis is discussed in the light of the histopathological findings.

[Intraarterial injection of Tolazolinhydrochlorid in retinal arterial occlusions. Our experiences with puncture of the carotid artery (author's transl)].

In partial and total retinal arterial occlusions we have been giving intracarotideal Tolazolinhydrochlorid since 1969. In the beginning we have prepared surgically the common carotid artery, at present this puncture is done percutanously. The author describes the surgical procedure and the results. A significant improvement of the visual acuity and of the visual field was present in the cases with intraarterial injection.
