Purpose: To evaluate the antioxidative effect of artificial tears in the treatment of keratoconjunctivitis sicca (KCS)., Material and Methods: The study included 43 patients (60 eyes) with severe KCS: 38 women (50 eyes) and 5 men (10 eyes) aged from 27 to 76 years (in average 52 years). Patients were randomly divided into 2 groups; all patients used therapeutic silicone hydrogel soft contact lens (SCL) and instillations of 0.05% Cyclosporin A (CyA) 2 times a day. Patients of the first group (22 people, 30 eyes) used 0.15% hyaluronic acid. In the second group, patients (21 people, 30 eyes) used a tear substitute with similar surface-active component, but with antioxidant properties. The results of the treatment were evaluated using basic and additional research methods at 1, 3, 6 and 12 months., Results: Corneal epithelialization was achieved after 1 month of conservative treatment in all patients who wore SCLs and were treated with instillations of 0.05% CyA and artificial tears. Then the lenses were removed and the patients were switched to instillations of CyA and artificial tears. Comparative analysis of the results showed that higher functional indicators were achieved in the second group, where patients used Artelac Rebalance drops with antioxidant properties., Conclusion: Improvement of clinical and functional parameters in the treatment of severe forms of KCS was achieved by direct action on both links of pathogenesis with minimal amounts of the drugs and the frequency of their use. Subsequent supportive therapy contributed to stabilization of the results and further increase of the functional parameters.

A new method has been developed for the treatment of severe forms of keratoconjunctivitis sicca (KCS) that involves the use of an original cyclosporine A (CyA) saturated soft contact lens (SCL) together with preservative-free artificial tears therapy., Aim: to evaluate the effectiveness of the newly developed treatment for KCS based on the use of medical SCL saturated with 0.05% CyA., Material and Methods: The patients (43 men, 60 eyes) with severe KCS were divided into 2 groups. Group 1 included 21 patients (30 eyes), who received artificial tears and wore 0.05% CyA-saturated silicone-hydrogel SCLs. Group 2 included 22 patients (30 eyes), who wore unsaturated original SCLs and received CyA instillations 2 times daily and, also, artificial tears. Apart from a standard ophthalmic examination, the assessment included Schirmer's test, Norn's test, vital eye stain tests, tear osmometry, laser confocal tomography of the cornea, optical coherence tomography of the anterior segment with meniscometry, impression cytology of the conjunctiva, tear pH measurement, plating of the content of the conjunctival cavity, measurement of the width of the palpebral fissure, and calculation of the ocular surface disease index. Treatment results were followed up at 1, 3, 6, and 12 months., Results: The use of 0.05% CyA-saturated SCLs allows to halve treatment time for patients with severe KSC (down to 1 week - 1 month) as compared to unsaturated original SCLs in combination with 0.05% CyA instillations and to reduce it 5 times as compared to 0.05% CyA instillations only., Conclusion: The new method of KSC treatment that involves the use of medical SCL of original design (ensures even distribution of 0.05% CyA across the ocular surface) and preservative-free artificial tears has demonstrated high therapeutic effectiveness as compared to existing methods.

Unlabelled: Laser confocal tomography of the cornea enables studying ultrathin sections of corneal layers, which provides additional reliable information on tissue changes in keratoconjunctivitis sicca (KCS)., Aim: To assess the significance of laser confocal tomography of the cornea in the diagnosis and monitoring of KCS., Material and Methods: We investigated 38 eyes of 30 patients with severe KCS. The patients were divided into two groups. Group 1 (15 patients, 19 eyes) was prescribed cyclosporine А 0.05% instillations 2 times daily, artificial tears, and soft contact lenses. Group 2 (15 patients, 19 eyes) received only instillations of cyclosporine А 0.05% 2 times daily and artificial tears. Besides standard ophthalmic examination, additional tests were performed, namely Schirmer's test, tear break-up time test, fluorescein eye stain test, tear osmolarity test (TearLab System, USA), and Heidelberg retinal tomography of the cornea (HRT, Heidelberg Engineering GmbH, Germany)., Results: HRT findings revealed a 3 times shorter epithelization period and faster recovery of corneal transparency in group 1 as compared to group 2 (1.5 and 4.5 months, respectively). There was also an evident reduction in the number of immune cells in the cornea, most pronounced in group 1 at 3 months, which is indicative of inflammation termination., Conclusion: The use of HRT of the cornea in KCS patients allows real-time cellular level observation of corneal changes, which together with clinical findings and diagnostic tests not only confirms the diagnosis but also determines treatment effectiveness. It has been also found that soft contact lenses accelerate epithelization of the cornea and relieve inflammation of the ocular surface in KCS patients under cyclosporine A 0.05% instillation therapy.

Fifty-three patients with eye diseases caused by autoimmune disorders received complex treatment involving extracorporeal techniques, such as hemosorption, plasmapheresis, and double cascade plasma filtration in combination with pulse therapy. Clinical, laboratory, morphometric, and biochemical studies show the efficacy of hemosorption in relieving acute manifestations of an inflammatory process and the stabilizing action of these methods on ocular epithelial tissue, immunological activity, and systemic manifestations of the underlying disease.

The authors describe effective surgical rehabilitation of a female patient with corneal perforation and subsequent complicated cataract developing against the background of chronic deficiency of lacrimal production associated with Sjogren's syndrome which developed in the presence of rheumatoid arthritis. Treatment with artificial tears during complex pre- and postoperative therapy prevented serious complications and made unnecessary the preliminary interventions aimed at inhibition of lacrimal production. Long remission of the underlying disease and stability of visual functions during 2 years evidence the efficiency of rehabilitative measures.
