If a large amount of anisometropia is present the brain is not able to figure out the difference in the images being viewed by two eyes. The brain will resolve to ignoring what one eye sees and eventually block it out all together. [glassescrafter.com]

It is possible for spectacle lenses to be made which can adjust the image sizes presented to the eye to be approximately equal. These are called iseikonic lenses. In practice though, this is rarely ever done. [en.wikipedia.org]

The deviated eye in these subjects presents a defective emmetropization compared to the dominant eye, which is normally aligned. [ncbi.nlm.nih.gov]

  Having anisometropia can result in having amblyopia and strabismus. Amblyopia is also sometimes called lazy eye. Strabismus is sometimes called crossed eyes. [my.clevelandclinic.org]

  When early hyperopia does not spontaneously reduce within the first year and a half of life, esotropia with anisometropia and amblyopia can develop. [ncbi.nlm.nih.gov]

Eyes that are two different sizes, having different conditions of the retina and requiring different treatments, a lens being replaced, and other surgeries can all result in aniseikonia. [glassescrafter.com]

Outlook / Prognosis What can I expect if I have anisometropia? If you have treatment for anisometropia when you’re very young, the outlook is quite good. Your eyesight might stabilize and you may not need corrective lenses. [my.clevelandclinic.org]

[…] anisometropia from - 3 to 3 D having a 75 to 94% probability of reaching a BCVA of 20/40 or better as compared to only 25% of this result in anisomyopic patients with more than - 6 D of interocular difference.[55] Complications As stated above in the prognosis [ncbi.nlm.nih.gov]

Epidemiology[edit] A determination of the prevalence of anisometropia has several difficulties. First of all, the measurement of refractive error may vary from one measurement to the next. [en.wikipedia.org]

Epidemiology The prevalence of anisometropia is age-dependent, with a higher prevalence amongst adults when compared to young children. [ncbi.nlm.nih.gov]

[…] condition was found in 4.5% of African Americans between the ages of 6 and 49 years and in 14.1%, 15 to 9%, and 12,3% of Australian, Chinese-Singaporean, and Spanish adults ranging from 40 to 79, 49 to 97 and 49 to 79 years of age, respectively.[28][25][29] Pathophysiology [ncbi.nlm.nih.gov]

A certain degree of natural iso-emmetropization has also been observed to intervene to prevent amblyopia; nevertheless, evidence exists that anisometropia and amblyopia tend not to resolve without treatment.[40] Optical correction is effective in preventing [ncbi.nlm.nih.gov]
