[The extent of bacterial contamination of keratoplasty donor eyes post mortem]. / Beitrag zum Umfang bakterieller Kontaminationen bei Keratoplastik-Spenderaugen post mortem.

In order to determine the initial bacterial contamination of corneal donor material the abraded epithelia from 125 donors, i.e., 250 globes, were examined immediately after enucleation. Of these, 49 (19.6%) were sterile, while 201 (80.4%) were contaminated. Monoinfection was identified in 174 globes and mixed infection in 27. The pathogen most frequently isolated was Pseudomonas aeruginosa. Neither the donor's age not the time elapsed between death and enucleation had any influence on the contamination rate. Prolonged hospitalization of donors leads to an increase in gram-negative bacteria. The necessity of antibacterial prophylaxis prior to keratoplasty is pointed out.

[Trabeculectomy--complications and their prevention]. / Trabekulektomia--powiklania i zapobieganie.

Advantages and disadvantages of various surgical methods in glaucoma are discussed. Particular attention is called to the occurrence of early and late complications after trabeculectomy. A technique of trabeculectomy in which--according to the author--one may expect the smallest number of postoperative complications is described.

[Follow-up after enucleation in choroid melanoma]. / Verlaufsuntersuchung nach Enukleation wegen Aderhaut-Melanom.

We report on 31 patients who underwent enucleation between 1976 and 1984 for uveal melanoma and had a mean follow-up of 107 months. There was no irradiation to the globe or orbit prior to enucleation, which was done under general anesthesia. Histology showed that: the average diameter of the tumors was 10.6 mm and the average height 6.2 mm. There were 3 cases of spindle-cell A-type tumors, 19 of spindle-cell B, 2 of mixed cell types, and 7 cases of mixed cell types with epithelioid cell dominance or epithelioid cell tumors. In September 1988, 9 patients (29%) had died as of a result of metastases from the melanoma; 4 patients who died were found to have another malignant tumor; 1 patient died due to cerebral apoplexia; 1 patient died 8 days after enucleation due to unknown causes. The survival curve was based on the Kaplan-Meier method.

[Examination of function by scintillography after dacryocystorhinostomy (author's transl)]. / Funktionsszintigraphische Untersuchungen nach der Dakryozystorhinostomie

By means of a radiotracer 99mTc-pertechnetate the function of the lacrimal system was determined after dacryocystorhinostomy. The results of the examinations demonstrate that the function of the lacrimal system is more quickly normalized if the lig. canthi int. is fixed to the periosteum of the os lacrimale.

[Initialphase of dark adaptation, sensibility to dazzling and diabetic retinopathy (author's transl)]. / Sofortadaptation, Blendungsempfindlichkeit und diabetische Retinopathie

In the early stages of development the diabetic retinopathy often causes disturbances of initial-phase of the dark adaptation even if other functional defects are not evident. In a group of eyes with normal vision of 153 diabetics (296 eyes), only 55% of the cases reached results, which correspond to the norm of nyktometry.

[Experiences with trepano-trabeculectomy (goniotrepanation) (author's transl)]. / Erfahrungen mit der Trepanotrabekelektomie (Goniotrepanation)

The authors report on a modificaioon of goniotrepanation according to Fronimopoulos where only the trabecular network is trepaned and the sclera is closed twice (trepano-trabeculectomy). The experiences, based on 172 operations of this kind showed, that the quick restoration of the anterior chamber after the operation reduces the postoperative complications. However, like the goniotrepanating operation the effect of the regulation of the intraocular pressure is based on the formation of a small filtering bleb. The operation is especially suitable for the treatment of primary glaucoma of adults.
