Evaluation of microvascular changes with the use of OCT-A in macular teleangioectasias of type 2
Purpose. To study the parameters of microvascular changes in the retina with their quantitative assessment by OCT-angiography. Materials and methods. The control group is consisted of 20 healthy eyes (group I), 20 eyes with type 2 macular telangioectasia without CNV (group II), and 20 eyes with macular telangiectasia with CNV (group III). All patients underwent optical coherence tomography with the function of angiography. Results. FAZ parameters: Group I 0.234±0.08, group II 0.357±0.05, group III 0.339±0.11. PERIM FAZ: I group 1.857±0.34, II group 2,971±0.36, III group 2.853±0.56. FD index: I group 53.48±2.73, II group 52.83±4.66, III group 54.18±6.39. Conclusion. In the course of the study, statistically significant increases were detected in the parameters of the FAZ and PERIM ingroup II and III compared to the control group.
