Relevance. "Uncomplicated pachychoroid" is a new concept, the main characteristics of which are local or diffuse thickening of individual layers of the choroid without damage to the retinal pigment epithelium. Purpose of the study. The aim of the research to study the informative value of the Sweep Source OCT method in the early diagnosis of uncomplicated pachychoroid in healthy individuals. Materials and methods. 30 "conditionally healthy" individuals (60 eyes) were selected for the main group. The control group consisted of 50 patients (63 eyes). The comparison group included 36 intact eyes of patients with pachychoroidal diseases. The central thickness of the choroid was measured on DRI Triton OCT (Topcon, Japan), operating using the Sweep-source technology, using TOPCON Advanced Boundary Segmentation (TABS) software in 9 segments of the macular zone. Results and conclusion. When measured using the TABS program, the thickness of the choroid exceeding 300 microns in the macular zone was observed in healthy individuals in 56.7% of cases (34 eyes). Linear scanning of thickened zones of the choroid in the Cross-Line mode revealed in 31.6% of cases (19 eyes) topographic violations of the choroid structure, which were manifested by local expansion of the vessel lumen of the Haller layer with moderate thinning of the vessels of the Suttler layer and choriocapillaries. At the same time, the contours of the pigment epithelium remained uniform and even. Autofluorescence of the fundus did not reveal changes in the retinal pigment epithelium in the areas of local thickening of the choroid, even with a violation of its anatomical structure. The high informativeness of the Swift Source OCT in the identification of an "uncomplicated" pachychoroid at the preclinical level has been proven. The presented morphological features of the choroid can be used as markers for the prognosis of the development of pachychoroidal diseases in healthy individuals.
