anisometropia
Pronunciation: an-ahy-suh-mi-TROH-pee-ah
Significant difference in refractive error between the two eyes.
Full Definition
Anisometropia is a condition where there is a significant difference in the refractive power between the two eyes, typically 1.5 diopters or more. This difference can involve myopia, hyperopia, or astigmatism and may lead to amblyopia in the more affected eye due to blur or image size differences. Children with anisometropia often favor the eye with better vision, potentially causing the other eye to become amblyopic. Treatment involves correcting the refractive error with glasses, contact lenses, or refractive surgery, along with amblyopia therapy if needed.
Usage
Usage note: Document the magnitude and type of refractive difference between eyes.
In Context
- "The patient had significant anisometropia with +1.00 D in the right eye and +4.50 D in the left." — Refractive examination results
- "Contact lens fitting was recommended to minimize aniseikonia from the anisometropia correction." — Treatment recommendation
