Treatment of Anisometropic Amblyopia with a Dichoptic Digital Platform in Argentinian Children and Adults

ABSTRACT

Purpose

To evaluate and compare the results of dichoptic training in Argentinian children and adults with anisometropic amblyopia.

Methods

Prospective non-comparative study enrolling 41 subjects with anisometropic amblyopia (age, 6–60 years old). Two groups were differentiated according to age, children (6–16 years, 24 subjects) and adults (>17 years, 17 subjects). All patients were treated with the Bynocs® platform (Kanohi Eye Pvt. Ltd, India) following a protocol of 30 sessions of training of 30 min daily 5 times a week for 6 weeks. Changes in corrected distance visual acuity (CDVA) and binocular function (BF) score with treatment were analyzed.

Results

In the whole sample, CDVA in the amblyopic eye improved significantly, with a mean change of 0.30 logMAR (p < .001). Likewise, a significant improvement was also found in BF score (p < .001), with a mean change of 1.14 log units. The change achieved in CDVA was significantly correlated with the baseline CDVA in the amblyopic eye (r=-0.568, p < .001). Furthermore, no significant differences were found between age groups in the change achieved in CDVA (p = .431) and BF with therapy (p = .760).

Conclusions

Dichoptic training with the digital platform evaluated provides an effective improvement of visual acuity and binocular function in children and adults with anisometropic amblyopia.
