What this trial studies

This observational project follows glaucoma patients who are prescribed Xiidra (lifitegrast 5%) as part of routine care to address ocular surface discomfort related in part to topical glaucoma medications. Participants are adults already using one or more topical glaucoma antihypertensives and reporting symptoms of ocular surface discomfort, while patients with recent ocular surgery or current topical cyclosporine or steroid use are excluded. Researchers will document symptom changes and tolerability after Xiidra prescription without altering the treating clinician's plan. The work is conducted at Doheny Eye Center UCLA in Fountain Valley, California, with treatment provided as standard of care.

Who should consider this trial

Good fit: Ideal candidates are people with glaucoma who are using at least one topical glaucoma eye drop, report ocular surface discomfort, and whose clinician plans to prescribe Xiidra as standard care.

Not a fit: Patients with a history of glaucoma filtration or ocular surface surgery, those who had incisional ocular surgery in the past six months, or those currently using topical cyclosporine or steroids are unlikely to benefit from this observational evaluation.

Why it matters

Potential benefit: If successful, this could reduce eye-surface discomfort and make glaucoma medication use more comfortable for affected patients.

How similar studies have performed: Lifitegrast (Xiidra) is FDA-approved and has shown benefit for dry eye disease in prior studies, but its specific effects in glaucoma patients on multiple topical medications have been less well studied.
