Brief Summary

Purpose: of determining the role of Interactive Binocular Treatment (I-BiTTM) as a complementary method of patching in amblyopia therapy. Materials and Methods: In this randomized clinical trial study, 50 unilateral amblyopic children (25 male/25 female) less than 10 years with either best corrected visual acuity (BCVA) ≤0.3 LogMAR (Logarithm minimum angle of resolution) in amblyopic eye or difference of VA≥2 lines between two eyes will be included. Patients will be classified in the case and control groups (25 in each), randomly. Patching will be recommended in both, cases will also received I-BiTTM. The child will be asked to play I-BiTTM games through glasses with conjugate colored filters. Patching was continued for one month more in both groups. VA and stereoacuity were measured at baseline, one month at the end of I-BiTTM treatment and one month after I-BiTTM treatment.

Recommendation of Patching

ACTIVE COMPARATOR

Patients will receive two hours of patching in the case of one line difference of best corrected visual acuity(BCVA) between two eyes during one month.

Other: Patching Therapy

Recommendation of Patching and interactive binocular treatment

ACTIVE COMPARATOR

Patients will receive interactive binocular treatment addition to patch therapy in the least of 4 to 5 days of a week within 20-30 minutes in each day during one month.

Other: Patching TherapyDevice: Interactive Binocular Treatment System

Interventions

Occlusion of a dominant eye with better best corrected visual acuity

Recommendation of PatchingRecommendation of Patching and interactive binocular treatment

Dissociation of two eyes with more foveal stimulation to the amblyopic eye
