One fixates accurately in order to see clearly not because one sees clearly.

Binocular gaze was measured accurately under natural conditions with the Maryland Revolving Field Monitor to determine how visual-clarity affects gaze-accuracy. The gaze of 3 unrestrained, seated subjects (2 presbyopes and 1 myope) was recorded as they tapped 4 LEDs with a long, narrow rod cemented to a thimble worn on their index fingers. They wore positive contact lenses, permitting very clear vision only nearby, within 35 cm.

[Laser coagulation of the retina in patients with diabetes after posterior-chamber lens implantation].

The possibility of laser coagulation of the retina after implantation of posterior-chamber lenses was examined in 44 patients with diabetes mellitus. Three-speculum Goldman's lens could be used to examine the central zone in 40 patients, the median periphery in 36 patients, and the utmost periphery in 6 patients. The principal causes impeding the examination of the retina were (1) posterior capsule opacity, (2) inadequate mydriasis because of synechias between the iris and the intraocular lens.

[Development of a system for assessment of work performance and quality during therapeutic-diagnostic processes in ophthalmology].

A system for estimating labor consumption in, and quality of the therapeutic and diagnostic process, based on the medicosocial and economic analysis of the current ocular morbidity structure in Russia, is suggested. This estimation system may be useful in condition of cost accounting relations introduction in research institutions of ophthalmologic profile.

[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).
