Binocular Amblyopia Treatment

Summary

To evaluate the effectiveness of enhanced binocular amblyopia treatments in achieving a more complete and stable recovery.

Description

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.

Late Ophthalmologic Referral of Anisometropic Amblyopia: A Retrospective Study of Different Amblyopia Subtypes.

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 treatment with contrast-rebalanced movies.

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 ...

Binocular vision and fixational eye movements.

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...

The effect of asymmetrical accommodation on anisometropic amblyopia treatment outcomes.

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...

Reading ability of children treated for amblyopia.

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...

Medical and Biotech [MESH] Definitions

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)
