Treatment Of Adult Amblyopia With Bynocs Dichoptic Therapy Is A Reality

Amblyopia is a neurodevelopmental disorder that is characterised by visual impairment unilaterally and less
commonly bilaterally along with compromised binocular visual function, which is not explained with structural abnormality.
The most common treatment for amblyopia is patching of the good eye to force the amblyopic eye to improve. Treatment
is effective if done at an early age; however, its effectiveness decreases in older children and adults. For adult amblyopia,
there is no accepted treatment to improve visual acuity. We aim to assess the efficacy of Bynocs Dichoptic Therapy in
adults with amblyopia to improve visual acuity and stereo acuity

In this cohort study, 50 adults were enrolled with a mean age of 43.2 years±16.4years. 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 one hour/day for 5 days in a week of dichoptic therapy at home settings.

50 subjects were included, and there was a mean improvement of 0.37 lines ±0.20 lines logMAR (almost four lines on the Snellen chart), p-< 0.0001 (Paired-t Test). Pre therapy 21 subjects had no stereopsis out of which 17 developed stereopsis with mean stereopsis of 397 sec of arc± 484 sec of arc.

Dicoptic therapy is an effective treatment for adults with amblyopia. It is also helpful to develop/improve stereopsis.
