Determining the Relationship between Anisometropia as Well as Visual Acuity, Aniseikonia and Stereopsis in the Absence of Strabismus | Chapter 9 | Current Practice in Medical Science Vol. 4

The goal of the current investigation was to ascertain the association between anisometropia type and its effects on stereopsis, aniseikonia, and monocular and binocular best-corrected visual acuity (BCVA) in the absence of strabismus.

162 individuals with anisometropia and healthy eyes who had never undergone eye surgery or therapy for amblyopia participated in the research. They were divided into four groups: spherical hyperopic anisometropia (SHA, n = 31), spherical myopic anisometropia (SMA, n = 45), astigmatic or cylindrical hyperopic anisometropia (CIIA, n = 22), and astigmatic or cylindrical myopic anisometropia (CMA, n = 64) based on spherical and cylindrical components and spherical The control group included of patients (NA, n = 188) who did not have anisometropia. Aniseikonia, stereoacuity, and anisometropia were investigated as effects of anisometropia on monocular and binocular BCVA.

In comparison to the SHA, SMA, CMA, and CHA groups, the NA group showed a considerably lower Logiv4AR of BCVA in the three eyes. Additionally, the Logiv4AR of BCVA was substantially lower in the SMA group compared to the CIIA group (p 0.05). The descriptive values of anjseikonia, however, did not significantly differ across the groups (p = 0.052). In comparison to the CMA and SHA groups, the SMA groups showed substantially lower stereoacuity values in logio arc seconds (p 0.05). The relationship between ahiseikoria and stereoacuity scores in logl0 arc seconds was substantially positive in the anisometropia group (r = 0.160; p = 0.041). Stereopsis was correlated with the kind of anisometropia and poor monocular and binocular BCVA.
