Patent ID: 8422750

Claim:
A method of producing a three-dimensional image of at least a part of the retina of an eye comprising the steps of: using an imaging system to obtain a two-dimensional wide-field image of said part of said retina; using a three-dimensional shape determination module to determine a three-dimensional shape for said part of said retina; and using a two-dimensional image modification module to modify said two-dimensional wide-field image of said part of said retina using the three-dimensional shape for said part of said retina to produce a three-dimensional image of said part of said retina, wherein the step of using a three-dimensional shape determination module to determine a three-dimensional shape for said part of said retina includes the steps of: assigning a shape to the whole of said retina; identifying the position of said part of said retina with respect to said whole of said retina; and using said assigned shape and said position of said part of said retina to determine said three-dimensional shape for said part of said retina, and wherein the step of assigning a shape to said whole of said retina includes selecting a general shape which approximates the shape of an eye and measuring at least one parameter of said retina, and using said at least one parameter to modify said general shape to obtain a specific shape of said whole of said retina of said eye, and assigning said specific shape to said whole of said retina, and wherein the step of identifying said position of said part of said retina with respect to said whole of said retina includes: determining a path of collimated light used to obtain said two-dimensional wide-field image of said put of said retina; and calculating the position of intersection of said path of said collimated light with said specific shape of said whole of said retina, and wherein the step of determining said path of said collimated light includes calculating said path of said collimated light from a source of collimated light to said retina, and wherein said calculation of said path of said collimated light includes determining distortion of said collimated light produced by the cornea of said eye and/or the lens of said eye.
