Aniseikonia Clinic Launched at IUSO’s Atwater Eye Care Center

This year, IU School of Optometry’s Clinical Assistant Professor Grace Brasel, OD, FAAO, launched the Aniseikonia Clinic at the school’s Atwater Eye Care Center. Dr. Brasel, who works in the pediatric and binocular vision department at both the Atwater Eye Care Center and Indianapolis Eye Care Center, is excited to bring this new and unique service to Bloomington, Indiana.

What is aniseikonia?
Aniseikonia is when the images from the two eyes are perceived as being different in size or shape. This can occur due to large differences in spectacle correction between the two eyes or due to retinal disease. Common retinal disorders that can cause aniseikonia are epiretinal membrane (macular pucker), macular edema, vitreomacular traction, and retinal detachment.

Symptoms of aniseikonia
Some individuals with aniseikonia can easily tell that one eye sees images larger or smaller than the other. However, for others, it may not be as clear. Individuals with aniseikonia may also experience symptoms of visual discomfort, headache, reading difficulty, double vision, distorted spatial perception, eyestrain, nausea, and dizziness.

What can I expect during an aniseikonia exam?
At the Atwater Eye Care Center, a very thorough evaluation will be performed assessing binocular vision and refractive error. Special testing is performed to measure image size differences between the eyes, important for the diagnosis of aniseikonia. If diagnosed with aniseikonia, Dr. Brasel will work with you to find the best solution to address your symptoms, whether it be contact lenses or a specialty spectacle lens design.
