[Quality management, possibilities and chances in ophthalmology].

German legislation introduced in 1988 called for obligatory quality assurance (QA) practice to be initiated by health care providers. In 1992 the scope of the legislation was extended. Opportunities for introducing quality assurance practice in ophthalmology are demonstrated through examples.

[Ophthalmological experiences with automobile drivers with inadequate vision].

A total of 369 ophthalmological practices were asked to report the number of patients seen within one test week who drove their cars but did not satisfy minimum legal requirements for diurnal visual acuity applicable for applicants for a West German Class 3 driver's license. There were 471 such patients. From this number it can be calculated that approximately 570 000 individuals (+/- 9%) drive cars in the Federal Republic of Germany with inadequate visual acuity.

[Reasons for postoperative deterioration of visual fields in cases of advanced primary open-angle glaucoma (author's transl)].

In 86 patients suffering from advanced glaucomatous field defects visual functions were evaluated up to 12 years postoperatively. There was a 50% deterioration in visual acuity in 29 eyes (34%). This was mainly caused by new cataract formation.

[Visual acuity and intraocular pressure after surgery in congenital glaucoma (author's transl)].

In 124 eyes (82 patients) a total of 152 trabeculotomies were performed. Re-examinations were done after three and six months and then every year. After at least three years pressure was controlled in 67 out of 80 eyes (84%).

[Contusion of the eye--secondary glaucoma and other late consequences (author's transl)].

24 patients were re-examined 19--20 years and another 37 patients 10--11 years after blunt injury to the eye. 24 eyes showed marked angle rears but there was not a single case of glaucoma. In case of initial a.

[Trabeculotomy and cataract-extraction: simultaneously or step by step? (author's transl)].

In 64 eyes the combined procedure (group I) and in 67 aphacic eyes a trabeculotomy (group II) was performed. There were different types of glaucoma. Re-examinations wer done 6 months and 1--10 years postoperatively.

[The influence of healing on the long-term effect of trabeculotomy in primary open angle glaucoma (author's transl)].

83 eyes underwent a re-examination 3-7 years after trabeculotomy. By surgery alone the diurnal curve in 58 out of 74 eyes (78 percent) was regulated. In the majority of the other eyes additional medication controlled the i.

[Tonographic and tonometric aqueous humor outflow tests after trabeculotomy (author's transl)].

In 10 eyes which trabeculotomy was performed because of primary open angle glaucoma preoperatively, 1 to 3 months and 12 months postoperatively the diurnal curves and tonographic results were compared. The i.o.

[Effect and complications of Vogt perforating cyclodiathermy in various forms of glaucoma].

In 178 eyes 223 perforating cyclodiathermies (PCD) have been performed. The technique described by Vogt was modified by additional coagulations around the insertions of the recti-muscles. This procedure was done if one or repeated glaucoma procedures (fistulas, iridectomies or trabeculotomies) were not successful of if these surgical methods were not reasonable because of the morphological conditions of the iris and the chamber angle.

[Tonometry and tonography for open Schlemm's canal (author's transl)].

In 13 eyes tonometry was performed during trabeculotomy at the beginning, after preparation of the outer scleral lamella and after the excision of the outer wall of the canal of Schlemm. In 4 eyes this was combined with tonography. There was no significant change of the averaged i.

[Observations on the pathogenesis of essential progressive iris atrophy with corneal dystrophy and secondary glaucoma (author's transl)].

A report is given of a case of a unilateral condition of this type in a 30-year-old woman, who was observed and repeatedly photographed for more as 7 years.

[Tonography after trabeculotomy (author's transl)].

In 25 eyes suffering from primary open angle glaucoma the facility of outflow was measured before and 1 to 3 months after surgery in consideration of the rigidity. Trabeculotomy improved the facility on an average of 0.14+/-0.
