摘要:
An OCT image of an eye which has been subject to a DSAEK corneal transplant, in which a Descements membrane in the cornea has been replaced by a graft, is processed to identify the outline of the graft. The process includes the steps of: computationally extracting the boundary of the cornea including the graft computationally detecting the corners of the graft computationally extracting points on the boundary between the graft and the original cornea and computationally fitting the points on the boundary between the graft and the original cornea smoothly into a curve. The outline of the graft is then displayed. A graft profile may be generated, indicating the thickness of the graft at each point along its length.
