Aniseikonia is a visual condition where there is a significant difference in the perceived size of images between the two eyes. This discrepancy can lead to various visual disturbances and discomforts, including headaches, diplopia (double vision), and difficulties with depth perception.
Causes[edit]
Aniseikonia can be caused by several factors, including:
- Refractive surgery: Procedures such as LASIK or cataract surgery can alter the refractive properties of the eyes, leading to aniseikonia.
- Aphakia: The absence of the lens in one eye can result in significant differences in image size.
- Retinal detachment: Surgical repair of a detached retina can sometimes lead to aniseikonia.
- Anisometropia: A significant difference in the refractive power between the two eyes can cause aniseikonia.
Symptoms[edit]
Individuals with aniseikonia may experience:
- Headaches
- Diplopia (double vision)
- Asthenopia (eye strain)
- Difficulty with depth perception
- Nausea and dizziness
Diagnosis[edit]
Aniseikonia is typically diagnosed through a comprehensive eye examination, which may include:
- Visual acuity tests
- Binocular vision assessment
- Retinoscopy
- Optical coherence tomography (OCT)
Treatment[edit]
Treatment options for aniseikonia include:
- Optical correction: Specially designed eyeglasses or contact lenses can help balance the image size between the two eyes.
- Vision therapy: Exercises and therapies aimed at improving binocular vision and reducing symptoms.
- Surgical intervention: In some cases, surgery may be necessary to correct the underlying cause of aniseikonia.
