ABSTRACT
Twenty four patients with retinal pigment dystrophy were subjected to examination of pupillary reaction. Evaluated was the amplitude of pupillary reaction on a standard light flash. The results received were compared with the field changes. It was noted that the amplitude is diminished depending on the changes in the visual field.

Presented are the results of a 3 years long observation of the pupillary reaction in patients with pigmentary retinal dystrophy who have been subjected to a complex treatment. The authors discovered a consistency between the changes in the visual field and the amplitude of the pupillary reaction.

The authors evaluated the tolerance of the rabbit eye to a new generation of polyester bands coated by polymethane polyester or by silicone. Investigations consisted on the application of episcleral implants made from polyester coated bands and--for comparison--of already well known polyester non-coated bands The eyes were removed on the 4th, 10th, 30th, 60th and 90th day after operation, macroscopically evaluated and fixed in formaline. The specimen were prepared from the spot of the applied implant together with a margin of surrounding tissues. Clinical observations, macroscopic evaluations as well as histopathological examinations showed a good tolerance of the silicone coated bands; it was discovered instead that the polyurethane coated bands are causing a more pronounced inflammatory reaction in the early postoperative period.
