ОСОБЕННОСТИ КРОВООБРАЩЕНИЯ ОРГАНА ЗРЕНИЯ ПРИ БОЛЕЗНИ ТАКАЯСУ

Purpose of this study.To study the features of the blood circulation of the organ of vision in Takayasu’s disease (TD). Material and methods. 50 patients with TD with lesions of brachiocephalic vessels were examined. All patients underwent general ophthalmological examinations, duplex scanning of the brachiocephalic arteries (BCA) and ophthalmic dopplerography. Results. Ophthalmoscopy revealed that 39 (78%) patients had narrowing of the retinal arteries, 40 (80,1%) patients had retinal vein enlargement, retinal haemorrhages in 20 (40%), disc neovascularization in 12 (24,1%) and cotton-wool lesions — in 7 (14%) patients. Duplex scanning of the vessels of the eyeball revealed that ischemia of the organ of vision on the side of the lesion of the brachycephalic vessels is not determined in all cases. Collateral circulation is compensated by stealing blood from the unaffected side. Conclusion. In Takayasu’s disease, 76% of patients, despite pronounced changes in the brachiocephalic vessels, the functional parameters of the eyeball remained within the normal range, which indicates the possible influence of other compensatory mechanisms during ischemia.
