[Time course of bioelectrical activity of retina in patients with pigmented abiotrophy treated by deoxinate].

Bioelectrical retinal activity was assessed before and after a course of deoxinate therapy and in a blind placebo test in order to assess the efficacy of this new drug in the treatment of patients with pigmented retinal abiotrophy. Time course of electroretinograms during deoxinate therapy indicated a significant positive effect of the drug on retinal function as regards a variety of electrophysiological parameters in 80-94% patients. Improvement of electroretinography data was paralleled by improvement of visual acuity, extension of visual fields, and decrease of scotomas.

[Pathological changes in the eyeball in tapetoretinal abiotrophy].

The authors sum up the results of comprehensive examination of all the principal structures of the eyeball in patients with tapetoretinal abiotrophy. Present-day methods of investigation were employed, that helped reveal a generalized pattern of the pathologic process in this condition. The detected shifts should be borne in mind when choosing a method for cataract extraction in such patients.

[Trans-scleral cryopexy in hemophthalmos of diabetic etiology].

Trans-scleral cryopexy (TSC) was carried out in 81 eyes with recurrent hemophthalmos of diabetic genesis. 73 patients were followed up after surgery for a period of 3 months to 5 years. Hemophthalmos resolved in 80 percent of eyes (completely in 60, partially in 20 percent).
