Binocular Home Treatment for Amblyopia: Gains Stable for One Year

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Vision Science

Background:

• Amblyopia, or 'lazy eye,' affects visual development in children.
• Effective amblyopia treatment is crucial for long-term visual function.
• Home-based, technology-driven treatments offer potential for improved accessibility.

Purpose of the Study:

• To evaluate the long-term outcomes of a binocular eye-tracking-based home treatment (CureSight) for amblyopia.
• To assess the durability of visual acuity and stereoacuity gains one year after treatment cessation.
• To determine the rate of amblyopia recurrence following treatment.

Main Methods:

• A prospective, multicenter, long-term follow-up observational study.
• 38 children with amblyopia were evaluated at 12 weeks and 27 at 1 year post-treatment.
• Main outcome measures included visual acuity (VA), stereoacuity, and amblyopia recurrence.

Main Results:

• Visual acuity gains were maintained at 12 weeks post-treatment and partially retained at 1 year.
• Stereoacuity and binocular visual acuity gains were sustained at both 12 weeks and 1 year.
• Amblyopia recurrence was observed in 5.3% of patients at 12 weeks and 20.4% at 1 year.

Conclusions:

• Binocular treatment with CureSight demonstrated sustained improvements in visual acuity and stereoacuity one year post-treatment.
• The observed gains were maintained without the need for additional amblyopia therapy.
• While generally effective, some recurrence necessitates ongoing patient follow-up.
