Quick- and long-term outcomes of binocular gaming versus patching in childhood amblyopia: a scientific overview and meta-analysis

The purpose of this research is to systematically evaluate binocular gaming with typical occlusion remedy for visible acuity enchancment in childhood amblyopia. We carried out a scientific overview and meta-analysis in accordance with PRISMA 2020 tips (PROSPERO CRD420251080735). PubMed, Scopus, Cochrane Library, and Google Scholar have been searched by way of June 2025 for randomized managed trials in youngsters aged 3-18 years with unilateral amblyopia. The major consequence was best-corrected visible acuity enchancment, expressed as standardized imply distinction (SMD). A random-effects mannequin was utilized with subgroup analyses by therapy period, pattern dimension, and affected person traits. Nine RCTs, together with 986 youngsters, met the inclusion standards. Pooled evaluation confirmed no important distinction between binocular gaming and patching (SMD 0.05, 95% CI – 0.2 to 0.3, p = 0.68) with substantial heterogeneity (I² = 65%). Subgroup analyses revealed time-dependent results: short-duration trials (≤ 6 weeks) favored binocular gaming (SMD 0.35, 95% CI 0.05-0.65, p = 0.02), medium-duration trials (8-12 weeks) confirmed no important profit, whereas long-duration trials (> 12 weeks) favored patching (SMD – 0.47, 95% CI – 0.72 to – 0.22, p < 0.001). Larger, high-quality trials persistently supported patching. Publication bias evaluation indicated small-study results, with trim-and-fill suggesting the true impact might favor patching (adjusted SMD – 0.15).

Conclusion:

Binocular gaming might present short-term advantages, however sturdy proof signifies patching is superior for long-term outcomes. After satisfactory refractive correction, typical occlusion remedy stays the really useful first-line lively therapy for amblyopia. Binocular gaming could also be thought-about as an adjunct or various for kids who’re unable to adjust to patching.

What is thought:

• Patching is an efficient customary therapy for childhood amblyopia. • Evidence for binocular gaming in contrast with patching has been inconsistent.

What is new:

• Binocular gaming exhibits short-term profit, however patching is superior long run. • High-quality trials assist patching as first-line; gaming could also be an adjunct.
