Aniseikonia is a vision problem where there is a variation in the size and shape of objects in the field of vision between the eyes. It can cause eye strain, dizziness, disorientation, and balance problems. Corrective lenses are used to treat the condition, and diagnosis requires an examination by an ophthalmologist.
Aniseikonia is a vision problem in which information about the size of objects in the field of vision varies between the eyes or along a plane of vision. People may also notice variations in shape. A simple test can be used to check for aniseikonia in patients by showing patients a picture and having them see it through both eyes and each eye separately to see if there are any distortions in size or shape between the eyes. This condition is treatable with corrective lenses.
Some people naturally have aniseikonia due to radically different visual acuity in both eyes or due to variations in the size and shape of the eyes themselves. In other cases, the condition can be induced by corrective lenses, especially when patients have different prescriptions and are complex. The variation can be subtle, but it can cause problems for the patient because the difference in visual field can cause a cascading series of visual errors.
People with aniseikonia often develop eye strain, dizziness, disorientation, and balance problems. They may have problems with depth perception and handling objects in their environment. They may also have difficulty processing visual scenes, something that can be potentially dangerous while engaging in activities such as driving or operating heavy machinery. When the difference in image size is very small, people may not realize what’s going on until they are evaluated by a doctor.
Treatment for aniseikonia usually involves grounded corrective lenses to address the problem and stabilize the size of the image. For people with an existing prescription to correct refractive errors, these lenses must be made specifically to address the underlying vision problem and aniseikonia. Surgical treatments aren’t available yet, but sometimes getting surgery to correct refractive errors or replace the eye’s lens with an artificial lens can make treating aniseikonia easier.
Diagnosing this condition usually requires an examination by an ophthalmologist. The doctor will examine the eyes, perform a series of vision tests to learn more about the patient’s visual acuity, and interview the patient about any vision or health problems they have found. This information can be gathered to develop a diagnosis, determine the severity of the problem, and work on a treatment plan. Patients may benefit from visiting an aniseikonia clinic, where they receive specialized care from eye care professionals who focus on this condition and have access to the latest diagnostic equipment and treatment options.
