Purpose
To ascertain whether conventional treatment can improve visual function in adults with amblyopia.
Methods
Sixteen patients aged 21–67 years old were instructed to wear glasses for refractive correction and to patch the non-amblyopic eye for at least 1 h per day. Visual acuity, measured with crowded optotypes for distance and near acuity, was checked every 3 months, and followed for a mean (SD) of 14.1 (4.2) months. Prognostic factors related to the subsequent results, an improvement of 3 or more lines logMAR in distance visual acuity, were evaluated.
Results
Of 16 patients, 5 (31 %) improved 3 or more lines of distance and 5 (31 %) in near acuity. The mean improvement in distance was 2.4 lines logMAR (95 % CI 1.4–3.5) and 2.4 lines logMAR for near acuity (95 % CI 1.5–3.3). Patients aged under 45 years (p = 0.0357) and with severe amblyopia (p = 0.0337), defined as a corrected distance visual acuity of worse than −0.699 logMAR, were associated with a good response.
Conclusions
Conventional treatment may improve the visual acuity of amblyopic eyes even in adult patients.
