Aniseikonia
Definition
A binocular ocular condition where there is a significant difference in the perceived size or shape of the visual images projected onto the cortex from each individual eye; aniseikonia. This fusion anomaly can be congenital or acquired following improper optical corrections for high anisometropia or post-cataract surgery, causing patients to experience headaches, eyestrain, double vision, and impaired spatial depth perception.
