Abstract

This paper presents a technique for selecting regions of interest in retinal angio-OCT images to quantitatively analyze choroidea parameters in order to detect ocular diseases. The significance of this research lies in the fact that choroideas are an important part of the eye responsible for nourishing the retina and maintaining its normal function. Disruptions in the choriodea lead to various eye conditions, including degenerative retina diseases and glaucoma. A method for assessing choriodeal conditions has been developed based on identifying areas without vascular signal in retinal angiographic OCT images. Additional indicators for estimating choriodean status have been proposed. Comparative analysis of parameters between norm and pathological classes was conducted. The results of this work may be useful for ophthalmologists and contribute to improved diagnosis and treatment for eye conditions.
