Popis: Aim: to identify clinical and laboratory biomarkers that determine the nature of the course of myopic choroidal neovascularization (mCNV) and the response to anti-VEGF therapy in women.Material and methods. A prospective non-randomized study was conducted in 52 patients (52 eyes) with active mCNV, treated with ranibizumab intravitreally, 0.5mg. After 12months, the suppression of CNV activity, the number of injections and the fellow eye inclusion in the pathological process were taken into account. There were 2 groups: with a favorable clinical course (n = 31, age – 33,0 ± 5,1 years, anterior-posterior axis (APA) 28,5 ± 0,3 mm) and an unfavorable clinical course (n = 21, age – 34,0 ± 4,1 years, APA – 29,01 ± 0,1 mm). Structural retinal changes, choroid thickness, retinal blood flow, and heart rate were evaluated using OCT and OCTA protocols (Optovue XR Avanti, USA). Studies were conducted before the start of therapy and then one time per month. The concentration of sex and pituitary hormones (ELISA analyzer “Immunohem-2100”), lipoprotein A, Apo B/Apo A (Accent 200 Cormay, Poland), coagulogram data (Helena C-2, UK), and the concentration of highly sensitive C-reactive protein in blood serum before the start of antiangiogenic therapy were studied once.Results. In the first group, 1.4 ± 0.7 ranibizumab injections were administered to suppress the CNV activity. In the opposite group – 3.5 ± 2.1 injections, in 73.7 % of cases, relapses were diagnosed, in 3 cases – primary CNV in the fellow eye. Clinical and laboratory biomarkers of the unfavorable clinical course of mCNV were identified: extreme choroidal thinning, highly organized membranes of a large area, dome-shaped deformation of the posterior pole, excess of the reference values of lipoprotein A, fibrinogen and highly sensitive C-reactive protein by two or more times, an imbalance of sex and pituitary hormones (excess of the reference values of prolactin, follicle stimulating hormone, cortisol, progesterone concentration decrease), a predominant change in the menstrual-ovarian cycle according to the type of amenorrhea and opsomenorrhea.Conclusion. Myopic CNV biomarkers in women allow predicting the response to anti-VEGF therapy, the formation of relapses and the inclusion of the fellow eye in the pathological process.
