Etiologic forms of dry eye syndrome according to the new classification

In the article the new classification of dry eye syndrome is submitted. Patients who were under supervision, were divided into 5 groups: with systemic and organic dry eye syndrome (DES), with corneal DES, with blepharo-conjunctival DES, with exogenous DES, with combined forms. Also forms were allocated according to volume of lacrimation and character of course. For treatment of the syndrome various preparations were used - Tears Natu-rale, Ophtagel, Vidisc, depending on stability of tear film and subjective sensations of patients.

Defection of function tear excretion and secretion of dry eye syndrome after the course of beam therapy concerning new growths of palpebrae and conjunctiva

In the article authors describe features of changes of lacrimal bodies at patients after beam therapy concerning new growths of palpebrae and conjunctiva and also the tactics of preventive and medical actions. 48 patients were examined and performed the research of tear excretion and tear secretion apparatus. In 1 month after the beginning of the course of beam therapy they were divided into 3 groups depending on the degree of severity of developed dry eye syndrome and the total doze of irradiation. Dry eye syndrome developed at 92,7 % of patients, it was revealed defection of permeability of tear excretion ways at 7,3 %. It was used drops Floxal 0,3 % and gel Vidisic for treatment, which showed high efficiency and can be recommended for preventive maintenance of beam complications.

Comparative pharmaco-economic analysis of modern preparations of artifical tear and cornea's reparative regeneration at patients with dry eye syndrome of senior age groups with accompanying diseases

It is planned to estimate the cost of treatment of dry eye syndrome at eldery patients with accompanying diseases. The research is designed for 6 months with guantity of patients - 100-150. Pharmacoeconomic technigues will be submitted by the analysis of cost of illness, cost-minimization analysis, cost-effectiveness analysis. The separate section of work will be devoted to studying of quality of life of patients with dry eye syndrome. It's planned to prove pharmacoeconomic efficiency of new preparations of artifical tear, to define the dependence between dry eye syndrome and somatic pathology.

Clinical features of dry eye in photorefractive surgery

The author studied the prediction of occurrence, current and therapy of dry eye syndrome after LASIK. 485 patients were examined and divided into 2 groups before operation: control and group of risk with defection of tear secretion. Before and after operation tear substitutes (Lakrisin, Tears Naturale, Lakrysifi) and viscostretchy preparation -0,18 % solution of Natrii hyaluronati were applied as well as the method of temporary occlusion of lacrimal canals. After LASIK critical terms of defection of tear secretion are are 1 week - 1 month - an "early" dry eye and over 3 months - "late" dry eye. Thus, optimum term for tear substitute therapy is 1-3 months after LASIK.

Influence of precorneal tear film quality at dry eye syndrome on aberration of its optical system

It's planned to investigate precorneal tear film quality at dry eye syndrome on aberration of its optical system. Three groups of patients will be examined: healthy people, patients with simulated defections of precorneal tear film and patients who underwent excimerlaser ke-ratorefractive operations. In result it's planned to develop a way of modeling of dry eye syndrome on healthy eyes, to study optical characteristics of eyes at patients after refractive operations.
