What management options are commonly used to address aniseikonia in ABV?

• A. Refractive correction or prisms
• B. Laser surgery
• C. Color filters
• D. Eye drops

Answer: (A)

Aniseikonia is a mismatch in perceived image size between the two eyes, which disrupts how the brain combines the two images. The most commonly used management is optical correction that reduces this interocular size difference. Refractive correction addresses the underlying anisometropia, aiming to equalize retinal magnification between eyes so the two images appear more similar in size. Spectacle corrections can help, and in cases with significant anisometropia, contact lenses are often preferred because they sit directly on the eye and minimize induced magnification differences compared with glasses. Prisms can be added when there’s also a misalignment that makes fusion difficult; by shifting one eye’s image toward the corresponding retinal point, prisms can improve binocular alignment and reduce the functional impact of the size disparity on fusion. Laser surgery isn’t typically used to manage aniseikonia because it alters overall refractive power and carries more risks, color filters don’t address image size differences, and eye drops don’t correct the underlying size mismatch.
