Investigation of Degree of Vitreous Opacities for Two Intraocular Lenses

Abstract

The vitreous is a transparent gel-like tissue filling the eyeball. It sometimes becomes turbid, and this state is called vitreous opacity. The vitreous opacity is examined through lens. The intraocular lens is an artificial lens, and there are two types of lens. In this study, we evaluate vitreous opacity for each type of lens. In the proposed method, the frames for evaluation are firstly selected and the evaluation area is detected. Secondly, the opacities are detected using frame subtraction method, and the degree of vitreous opacity is calculated. In the experiments, the proposed method is applied to the actual image, and the results are verified for each type of lens.
