Abstract:
We describe a new method of obtaining three-dimensional (3D) images of detached retina. Twelve-slice photos of the partial retina were obtained according to the twelve positions on a clock face. Twelve sections were then cut from these photos and joined together. Each sector was resized to match nearby sectors and the complete retinal picture was then created. A sphere mapping algorithm was used to map the two-dimensional (2D) picture to a sphere, which was then used to simulate the actual eyeball. Finally, a 3D image of the entire retina with a clearly visible detached section was created by the Visualization Toolkit (VTK).
