Summary

This study tests whether wearing the right glasses can improve vision in adults with amblyopia (lazy eye). Researchers will measure how well participants see before, during, and after wearing custom spectacles. The goal is to see if the adult brain can still learn to see better with just optical correction. 36 adults aged 18-39 with lazy eye will take part.

Participants

About 36 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2022

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * 18-39 (inclusive) years of age * Anisometropic amblyopia (difference of ≥0.50D spherical equivalent or ≥1.50D astigmatism between eyes) or mixed mechanism amblyopia (strabismus and anisometropia) * Best corrected visual acuity (BCVA) in the amblyopic eye of 0.3 logMAR to 1.0 logMAR (inclusive) * BCVA in the non-amblyopic eye of 0.1 logMAR or better, and an interocular VA difference of 2 logMAR lines or more * Difference of 1.00D or more between current refractive correction and study prescription * Good general health Exclusion Criteria: * Other pathological ocular anomalies known to cause reduced visual acuity * Presbyopia (based on amplitude of accommodation) * Inability to tolerate prescribed refractive correction in spectacles (e.g., due to aniseikonia) * Contraindication to cycloplegic eye drops * Currently under amblyopia treatment/therapy * Inability to comprehend test instructions and/or provide consent * Eccentric fixation * \>-6.00DS of myopia in either eye with spectacles * Bilateral amblyopia * Presence of amblyopia that is not due to strabismus and/or anisometropia * Presence of (current or previous) psychiatric, visual, or neurological disorders
