Purpose
To assess the efficacy of Bynocs Dichoptic Therapy in adults with anisometropic amblyopia to improve visual and stereo acuity.
Setting
Wellington Eye Clinic, Dublin, Ireland
Methods
In this cohort study, 58 adults were enrolled with a mean age of 40.3 years ±16.0 years. Subjects who were diagnosed with anisometropic or residual amblyopia, did not respond to 100% compliance of 6 hours/day patching for at least 3 months and full time spectacle correction were included in the study. Subjects with deprivational amblyopia or any other ocular comorbidity or neuronal defects were excluded. Subjects were given dichoptic therapy for one hour/day for 5 days/week for 6 weeks of dichoptic therapy in the home setting. Those who felt that they were still improving after 6 weeks were allowed to continue therapy for a further 1-6 weeks.
Results
Fifty-eight subjects were included, and there was a mean improvement of 0.40 Logmar lines ±0.20 lines, p-< 0.0001 (Paired-t Test). Pre-therapy, 24 subjects had no stereopsis, of which 20 developed stereopsis with a mean stereopsis of 200 sec of arc± 400 sec of arc.
Conclusions
This new dichoptic therapy is an effective treatment for adults with anisometropic amblyopia. It is also helpful in developing/improving stereopsis.
