ANISEIKONIA

Aniseikonia (pronounced "an'ih-si-ko'ne-ah") is the visual condition in which a difference in image size exists between the two eyes. Typical symptoms are described above. A thorough binocular vision and aniseikonia evaluation by an optometrist with experience treating patients with aniseikonia is required to confirm the diagnosis and decide on a treatment plan. Common recommendations may include custom-designed iseikonic lenses (a.k.a. size lenses) and/or contact lenses. Vision therapy (a.k.a. orthoptics) and a prismatic prescription may simultaneously be employed to treat associated binocular dysfunctions (eye teaming problems) and/or accommodative dysfunctions (eye focusing problems).
