TREATMENT OF DEGENERATIVE CHANGES IN THE EPITHELIUM OF THE OCULAR SURFACE WITH "DRY EYE" SYNDROME

Abstract

According to recent studies, the prevalence of dry eye syndrome makes up 14% of cases in patients under the age of 50 years and 65-75% in patients over 50 years of age. Risk factors for the development of dry eye syndrome include aging, stress, side effect of frequent instillations of eye preparations, exposure to radiant energy, and diabetes mellitus. Therefore, the purpose of this study is to investigate the possibility of using “Delargin”, an antioxidant medicine, in the treatment of dry eye syndrome. 50 patients (100 eyes) aged 30-70 years were examined at the Department of Ophthalmology and then divided into three groups depending on the treatment used. Group 1 included 10 patients (20 eyes), who were prescribed to instil Oksial eye drops. Group 2 included 10 patients (20 eyes), who received basic therapy by instilling a solution of sodium salt of hyaluronic acid 0.0015 g / ml. Group 3 involved 20 patients (40 eyes), who instilled Delargin and hyaluronic acid. Monitoring the effectiveness of the treatment was carried out using the following methods: to assess basal tear production, a Schirmer 1 test was performed using the Ophthalic Test diagnostic bands (India); a Norn test was performed to control the stability of the tear membrane. Fluorescence test (staining of the cornea with 1% sodium fluorescein solution) was applied to detect corneal defects; Lipcof test was used to assess the degree of lid-parallel fold formation of the bulbar conjunctiva relative to the costal margin of the lower eyelid. As a result of the treatment, the patients of the Group 1 demonstrated that the Norn test scores increased to some extent from 6.8 ± 0.1 s up to 7.5 ± 0.1 s; in the patients of the Group 2 following the treatment, it was 8.5 ± 0.2 s and in the Group 3, the Norn test values were 11.2 ± 0.2 s (P<0.05). The frequency of blinking movements decreased significantly and approached the normal. It has been found out that the therapy of dry eye syndrome that includes the antioxidant Delargin, can significantly promotes normalizing of parameters typical for this process.
