[Secondary glaucoma mechanisms (author's transl)].

A new classification of the glaucomas concerned with the mechanisms of the intraocular pressure rise is presented. We differentiate hyperproduction and outflowblock glaucomas. The latter are divided into pre-, intra- and postrabecular forms. It is stressed that a gonioscopically open angle can be hydrodynamically closed and vice versa. This classification is based on the anatomical location of the outflow blockage and not on the gonioscopic impression.

[Unstable steroid-dependent hypotony-hypertony-syndrome (author's transl)].

The author reports an unusual case of a marked hypotony-syndrome without a recognizable cause, occurring after a previously operated chronic angle block glaucoma. On the assumption of a minimal cyclitis local corticosteroid therapy was commenced and lead to recovery of visual function. There were, however, problems in stabilizing intraocular tension both upwards and downwards. The steroids could not be withdrawn, even after 6 months, without the hypotony reappearing. On the other hand, the use of 2 drops of Decadron (dexamethasone) daily lead to tensions above 40 mmHg. The clinical situation is interpreted as a steroid-dependent hyposecretion-normosecretion in the presence of an occluded chamber angle.

[Pyoderma vegetans of the eye-lid (author's transl)].

A cases of Pyoderma vegetans attacking only the outer skin of the eyelid and leaving free the conjunctiva is reported. The diagnosis of this rare condition, belonging to the pemphigus diseases, depends on clinical course and especially on histological investigation. The aetiology of Pyoderma vegetans still remains unknown, an immun-pathological mechanism is discussed.

[Glaucoma in the presence of chalcosis (author's transl)].

There are only few reports in the literature about the coincidence of a glaucoma with a chalcosis. After briefly presenting such a case the authors discuss the differential diagnosis; a strictly monocular chronic simple glaucoma, a contusion glaucoma or a glaucoma secondary to chalcosis. Since glaucoma and chalcosis coincide so infrequently there is no basis for assuming a true secondary glaucoma due to chalcosis existing, as is the case with siderosis.

Intraocular fibrous proliferation as an incisional complication in pars plana vitrectomy.

We enucleated an eye of a 39-year-old white man four weeks after partial pars plana vitrectomy was carried out for removal of an amagnetic foreign body which failed. Vitreous clouding complicated the perforating injury. Histological findings included massive ingrowth of fibrous tissue into the vitreous space and along preretinal planes, total retinal detachment with degenerations, and localized proliferations of the pigmentary epithelium. All proliferations originated at the site of the sclerotomy incision.

[Association of Posner-Schlossman-syndrome with Adisson's disease (author's transl)].

After introductory remarks concerning the Posner-Schlossman-syndrome (syndrome of glaucomatocyclitic crises) a case is reviewed. The concurrence with Addison's disease in this patient gives rise to speculations as to possible connections between the two conditions, but the conclusion is that the simultaneous occurrence of the two diseases at present must be regarded as coincidental.

Accommodative effects of aceclidine in the treatment of glaucoma.

In 18 patients, 2% pilocarpine, 2% pilocarpine plus tropicamide 10:1, and 2% aceclidine were tested with respect to the degree of spasm of accommodation induced by these drugs. Aceclidine had the least effect on accommodation, making it the recommended drug for use in patients with glaucoma and considerable remaining accommodation, i.e., most patients under the age of 50 years.

[Long-term results of laser-trabecular-puncture (author's transl)].

A report on 38 eyes with glaucoma simplex that were treated by laser-trabecular-puncture 2 years ago is given. By this method one attempts to perforate the trabecular meshwork by means of a laser beam. Gonioscopy revealed that the pores had become occluded by scar tissue and goniosynechiae. In only 3 eyes (7.9%) was the intraocular tension lowered. The hypothesis is made, that in these cases contracture of scar tissue in the iris tissue led to a pull on the trabecular network and hence to an improvement of liquor drainage.

Melanocytoma of the iris with rapidly developing secondary glaucoma.

A 28-year-old woman with an upper nasal iris mass developed secondary glaucoma within a few months of presentation. Although the elevated pressure responded to medical therapy, in the interests of a definitive diagnosis as well as prevention of damage to the trabecular meshwork, surgical management was decided upon. Tumor excision was performed through a double-layered sclerolimbal flap. Light and electron microscopic examinations of the tissue revealed a partially necrotic iris melanocytoma. Six months after surgery, the patient's best corrected visual acuity was 20/30 in the affected eye, and the intraocular pressure was 21 mmHg without therapy. The lens remained clear. The differential diagnosis and management of melanocytomas, particularly the role of biopsy, are discussed.
