Measuring Thickness of Choroid Layer and Segmenting Choroidal Vessels in Retinal OCT Images

Tin Tin Khaing

The choroid has been suggested as a vascular biomarker of the eye in diagnosing early stages of various retinal diseases. Retinitis pigmentosa (RP) is a genetic disorder, characterized by the progressive cell loss in the retina, resulting the thinner choroid layer and change in diameter of the choroidal vessels. Optical coherence tomography (OCT) is an imaging modality that enables to visualize the cross-sectional view of the retina. Manual segmentation of the vessels and the layer in an OCT image is time-consuming and troublesome. Thus, we aim to implement an automatic technique of measuring the thickness of the choroid layer and segmenting the vessels in OCT images of RP patients based on a deep-learning model.
