The invention discloses application of oroxylum indicum total flavonoids in preparation of a medicine for treating uveitis. Experiments prove that the eye drops taking the oroxylum indicum total flavonoids or the oroxylin A as the active ingredient can reduce the uveitis eye inflammation and retina injury degree and reduce the infiltration quantity of inflammatory cells. The oroxylum indicum general flavone is taken as an oral medicine, so that inflammatory infiltration cells of a vitreous cavity and an iris-ciliary body can be reduced, bleeding symptoms can be effectively improved, hyperplasia of iris-ciliary body tissues can be inhibited, and infiltration of leukocytes of aqueous humor in mouse eyes can be effectively inhibited.

The present invention belongs to the technical field of computer image processing, and specifically discloses a method applicable to measuring multiple indexes of the ciliary muscle and scleral structure of the human eye, including obtaining a grayscale image of the ciliary body part; preprocessing the grayscale image; identifying and performing instance segmentation on the ciliary muscle to obtain a ciliary muscle mask; performing morphological processing on the obtained ciliary muscle mask, including screening out the contour with the largest area in the ciliary muscle mask to calculate the ciliary muscle area, ciliary muscle perimeter, ciliary muscle length, ciliary muscle thickness, scleral thickness, and maximum ciliary muscle thickness; measuring relevant angles of the ciliary muscle, and the relevant angles include the anterior angle of the ciliary muscle, the caudal angle of the ciliary muscle, the inferior angle of the ciliary muscle, TCA, ICA, and the anterior chamber angle. This technical solution can complete the automatic measurement of relevant parameters of the ciliary muscle and sclera, improve the efficiency in medical research and clinical work, without manual intervention, eliminate the interference of human factors, and the results have strong repeatability.
