METHOD FOR DETERMINING TYPE OF TAMPONADE OF VITREAL CAVITY WITH PREOPERATIVE USE OF GLOBAL TESTS FOR ASSESSING THE STATE OF HAEMOSTASIS IN SURGICAL TREATMENT OF RETINAL RUPTURES USING PLATELET-RICH BLOOD PLASMA Russian patent published in 2024 - IPC G01N33/48 A61F9/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be used to determine the type of vitreal cavity tamponade with the preoperative use of global tests for assessing the state of haemostasis in the surgical treatment of retinal ruptures using platelet-rich blood plasma. That is ensured by preoperative evaluation of fibrin clot formation/lysis (in vitro) in patient. Global test "Thrombodynamics" is used to determine the clot size at 10 minutes and the clot optical density. Global spatial fibrinolysis test is used to study the fibrinolysis onset time. Based on the obtained data, the type of tamponade of the vitreal cavity is determined. If the clot size at 10 minutes is 300 mcm and more, the optical density of clot is 25,000 standard unit and more, the onset of fibrinolysis of 30 minutes and more shows the completion of the operation in a liquid medium. If the clot size at 10 minutes is less than 300 mcm, the optical density of the clot is less than 25,000 standard units, the onset of fibrinolysis is less than 30 minutes, the operation is completed by air tamponade for at least 3 days.

EFFECT: invention provides preoperative determination of the type of tamponade of the vitreal cavity: air tamponade or completion of operation in liquid medium, high anatomical and functional result of treatment, no risk of non-closure or unblocking of the retinal rupture in the postoperative period, no need for repeated treatment.
