MOLNDAL, Sweden Visual acuity was essentially stable in amblyopic eyes more than 10 years after treatment cessation, a long-term study found.
Researchers here studied 24 patients with unilateral amblyopia caused by strabismus or anisometropia to determine treatment results. Mean follow-up time was 10.4 years.
For the amblyopic eyes, 17% deteriorated in visual acuity, 50% were stable and 33% gained in visual acuity. For non-amblyopic eyes, 8% lost one line of visual acuity, 38% were stable and 54% gained in visual acuity. The increase in acuity for the non-amblyopic eyes was significant. All straight-eyed anisometropic amblyopia patients showed a distinct decrease in magnitude of anisometropia, researchers said.
The study is published in the October issue of British Journal of Ophthalmology.
