Meridional aniseikonia-causes, symptoms, and therapies.

Journal Article (Journal Article)

BACKGROUND: The term aniseikonia refers to the two eyes' appreciating different image sizes when viewing the same object. Meridional aniseikonia can occasionally cause significant distortion of the binocular spatial sense in perceptive patients. METHODS: The medical records of 3 adult patients who complained of binocular spatial distortion consistent with meridional aniseikonia were reviewed retrospectively. Detailed descriptions of symptoms, ocular findings, and management are reported. RESULTS: Each patient had undergone a refraction-altering surgical procedure, and each complained of binocular spatial distortion characterized by a trapezoidal view of square or rectangular shapes. Each patient improved following management of the astigmatic correction. CONCLUSIONS: Patients requiring a new astigmatic correction following cataract or corneal surgery may complain of binocular spatial distortion caused by meridional aniseikonia.
