Mild | Severe | |
Isolated anterior | Retrolental plaque without extension onto ciliary processes±cataract. No stalk or attachment to posterior pole. (1 eye (2%) of 1 patient) | Retrolental plaque (often with vessels) with extension onto ciliary processes±cataract. No stalk or attachment to posterior pole. (3 eyes (7%) of 3 patients) |
Isolated posterior | Stalk or retinal fold with minimal to no optic nerve or macular distortion. No attachment to lens or ciliary processes. (1 eye (2%) of 1 patient) | Stalk or retinal fold with optic nerve or macular distortion. No attachment to lens or ciliary processes. (0 eyes) |
Combined anterior-posterior | Stalk (with minimal to no distortion of the optic nerve or macula) connecting posterior pole to retrolental plaque without extension onto ciliary processes±cataract. (23 eyes (50%) of 23 patients) | Stalk (with moderate to severe distortion of the optic nerve or macula) connecting posterior pole to retrolental plaque with extension onto ciliary processes±cataract.
