Abstract
A method and apparatus of producing a three-dimensional image of at least a part of the retina of an eye is provided. The method including obtaining a two-dimensional wide-field image of said part of said retina, determining a three-dimensional shape for said part of said retina and using the three-dimensional shape for said part of said retina to modify said two-dimensional image to produce a three-dimensional image of said part of said retina. The apparatus including an imaging system adapted to provide a two-dimensional wide-field image of said part of said retina, a three-dimensional shape determination module adapted to determine a three-dimensional shape for said part of said retina, and a two-dimensional image modification module adapted to modify said two-dimensional wide-field image of said part of said retina using said three-dimensional shape to produce a three-dimensional image of said part of said retina.
