Abstract
We present two versatile and reliable methods of determination of the corneal limbi localization from OCT images. These methods are fully automatic and are based on the purely geometrical dependencies of corneal shape, backgrounded by anatomical structure of the corneoscleral area. The first method enables to estimate the position of the point of corneoscleral junction (CSJ) at the anterior surface of the cornea. The second method can be used for automatic retrieval of the limbal point at the posterior surface of the cornea, which plays an important role in quantification of the irido-corneal angle.
