To evaluate the effectiveness of enhanced binocular amblyopia treatments in achieving a more complete and stable recovery.
To date, all studies of contrast-rebalanced binocular amblyopia treatment games used the same 10% per day contrast-increment that was designed for short-term intervention studies lasting 1-4 weeks; i.e., after 18 days of successful game play, both eyes viewed 100% contrast (no contrast-rebalancing).This study will investigate two alternative protocols designed to extend the game treatment period beyond 4 weeks to allow for more complete recovery of visual acuity. The new protocols will be compared with the original 10% contrast-increment game protocol in an 8-week 3-arm RCT to determine whether one or both of the new protocols is more effective than the current 10% increment.
Based on pilot data, we expect about 40% of amblyopic children to achieve normal visual acuity in 8 weeks. In an effort to also promote recovery of binocular vision, children who attain ≤0.4 logMAR at 8 weeks will be enrolled in stereoacuity training at the 8-week visit for the next 4 weeks. Children with residual amblyopia (BCVA >0.4 logMAR) at the 8-week visit will be provided with dichoptic movies for additional amblyopia treatment for another 4 weeks.

Amblyopia is characterized by a reduction in visual acuity, contrast sensitivity, and binocular visual functions. The two main causes of amblyopia are anisometropia and strabismus which al...
The purpose of the study is to compare the efficacy of 1 hour/day of binocular game play 5 days per week plus spectacle correction with spectacle correction only, for treatment of amblyopi...
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 clinica...
The purpose of this study is to investigate the effect of amblyopia therapy on cases who will receive Interactive Binocular Treatment (IBiTTM) without patching compared with those who will...
Amblyopia, or lazy eye, is best defined by the AAO as a unilateral or bilateral reduction of the best corrected visual acuity that occurs in the setting of an otherwise normal eye, or a st...
Amblyopia requires a timely diagnosis and treatment to attain maximum vision recovery. Specialty literature is lacking on how early amblyopia is referred. We aimed to understand if there are mean age...
Binocular amblyopia treatments promote visual acuity recovery and binocularity by rebalancing the signal strength of dichoptic images. Most require active participation by the amblyopic child to play ...
The aim of this study was to assess the relationship between binocular vision and fixation stability (FS). Across three experiments, we investigated (a) whether fixation was more stable during binocul...
Previous research has revealed that the majority of children with anisometropic amblyopia have asymmetrical accommodation. The aim of this preliminary study was to determine whether the type of accomm...
Previous studies have reported compromised reading ability in children with amblyopia. Standardized psychoeducational test norms have not been used; therefore, the practical consequences of poor readi...
A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.
An extract of absinthium and other bitter herbs, containing 60% alcohol. Prolonged ingestion causes nervousness, convulsions, trismus, amblyopia, optic neuritis, and mental deterioration. (Dorland, 27th ed)
The study and treatment of defects in binocular vision resulting from defects in the optic musculature or of faulty visual habits. It involves a technique of eye exercises designed to correct the visual axes of eyes not properly coordinated for binocular vision.
Games designed to provide information on hypotheses, policies, procedure or strategies.
A form of interactive entertainment in which the player controls electronically generated images that appear on a video display screen. This includes video games played in the home on special machines or home computers, and those played in arcades. (McGraw Hill Encyclopedia of Science & Technology, 7th ed, v19, p223)
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
