Abstract
Purpose. Clinical and laboratory studies of the hemostasis system in patients with optic nerve vasculitis. Materials and methods. Medical records and case history of 45 people (49 eyes) were analyzed, of which pathology in two eyes was detected in 4 people (8 eyes). The study involved 24 men and 21 women aged 17 to 35 years. The follow-up period ranged from 3 months to 5 years. Standard ophthalmic research methods and special research methods were used. Laboratory methods for the study of hemostasis included the detection of lupus anticoagulant was carried out using poison tests, as well as confirmatory tests with donor plasma and corrective phospholipids. Results. Retinopathy of the type of venous stasis was found in 30 people, neuropathy of the type of stagnant disc – in 15 people. In young patients after a viral infection with damage to the optic nerve in clinical form, retinopathy such as venous stasis and congestive optic nerve head with lupus anticoagulant was found in 73.4% of cases. In patients with vasculitis of the optic nerve with lupus anticoagulant, disturbances in the vascular-platelet and plasma-coagulation links in the hemostatic system were revealed. Conclusion. Lupus anticoagulant significantly reduces thromboresistance of the endothelium of the retinal microvasculature and enhances hypercoagulation, breaks the natural regulation of the hemostasis system and aggravates ischemia of the retina, optic nerve, participates in the pathogenesis of clinical forms of optic nerve vasculitis. Key words: hemostatic system, lupus anticoagulant, thrombophilia, optic nerve vasculitis.
