THEORETICAL RATIONALE FOR STUDYING ENDOTHELIN-1 AND D-DIMERS IN THE BLOOD AND TEAR FLUID OF PATIENTS WITH HYPERTENSIVE ANGIORETINOPATHY

Currently, to identify various ophthalmological diseases, in addition to instrumental research methods, methods of laboratory analysis of tear fluid are used for practical and scientific purposes as an informative biological medium. The profile of changes in the biochemical parameters of this fluid is, as a rule, more pronounced and different in comparison with blood serum. It is known that tear fluid is mainly secreted by the accessory lacrimal glands and the main lacrimal gland, which is supplied with blood through the lacrimal artery, which is a branch of the ophthalmic artery
