Is this trial a fit for you?
✓Likely a good fit
Adults with baseline ocular redness (0.5 or higher in at least one eye and greater than 1.0 in both eyes on a standardized scale) who are willing to follow study visits and have a history of redness relief drop use or interest in using them.
✕Probably not a fit
Individuals without ocular redness at screening or those with contraindications to the study drug may not benefit.

What this trial studies
This Phase 3 trial evaluates the efficacy and safety of Apraclonidine Ophthalmic Solution, 0.125% (unit-dose, preservative-free) versus its vehicle for adults with ocular redness due to minor irritations. Participants receive a single dose in each eye on Day 1 and are followed for about one week with three in-office visits to assess redness before and after administration at predefined timepoints. Eligibility requires informed consent, recent experience with redness-relief eye drops or interest in using them, and measurable ocular redness at screening and prior to dosing. Exclusion criteria include intolerance to study components, recent ocular surgery, and other protocol-defined exclusions.
Why it matters
Potential benefit: If successful, the treatment could provide quicker or greater relief of ocular redness with a convenient single-dose regimen.
How similar studies have gone: Previous studies with adrenergic agonist eye drops have shown redness relief in similar populations; this study tests a specific formulation in a defined Phase 3 setting.
