Aniseikonia is a condition characterized by a significant difference in the perceived size of images between the two eyes, which can lead to visual discomfort and difficulties in depth perception. This condition is classified under the ICD-10 code H52.32, which falls within the broader category of disorders of refraction and accommodation.

Clinical Description of Aniseikonia

Definition and Symptoms

Aniseikonia occurs when there is a disparity in the size of the images seen by each eye. This can be due to various factors, including differences in refractive error, lens magnification, or even anatomical differences between the eyes. Patients may experience symptoms such as:

• Visual Discomfort: Patients often report discomfort or fatigue when using both eyes together.
• Depth Perception Issues: The difference in image size can impair the ability to judge distances accurately.
• Diplopia: Some individuals may experience double vision, particularly when focusing on objects at varying distances.
• Headaches: Prolonged visual strain can lead to headaches, especially after extended periods of visual tasks.

Causes

Aniseikonia can arise from several underlying conditions, including:

• Refractive Errors: Significant differences in refractive errors (e.g., one eye being more nearsighted or farsighted than the other) can lead to aniseikonia.
• Surgical Interventions: Procedures such as cataract surgery or refractive surgery (e.g., LASIK) can alter the optical properties of the eye, potentially resulting in aniseikonia.
• Contact Lens Use: The use of contact lenses with different powers or designs can also contribute to the condition.

Diagnosis

Diagnosis of aniseikonia typically involves a comprehensive eye examination, which may include:

• Visual Acuity Tests: To assess the clarity of vision in each eye.
• Refraction Tests: To determine the refractive error of each eye.
• Aniseikonia Testing: Specialized tests, such as the use of aniseikonia tests (e.g., the New Aniseikonia Test), can quantify the degree of image size difference.

Treatment Options

Management of aniseikonia focuses on alleviating symptoms and improving visual comfort. Treatment options may include:

• Corrective Lenses: Prescription glasses or contact lenses that equalize the image size perceived by both eyes.
