What this trial studies

This clinical trial aims to evaluate the effectiveness and safety of insulin eye drops for managing dry eye disease in patients who are already receiving topical hypotensive treatment for glaucoma. Participants will be randomly assigned to receive either insulin eye drops or a placebo (artificial tears) and will attend follow-up visits at baseline, 1, 3, and 6 months to assess their condition. The study is conducted in Madrid, where patients with dry eye and glaucoma will be recruited from an ophthalmology clinic. The primary focus is to determine if insulin eye drops can provide additional relief for dry eye symptoms in this specific patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with controlled ocular hypertension or glaucoma who also have a diagnosis of dry eye.

Not a fit: Patients with uncontrolled glaucoma or severe dry eye requiring immediate treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for glaucoma patients suffering from dry eye disease.

How similar studies have performed: While the use of insulin in eye drops is a novel approach, similar studies exploring alternative treatments for dry eye have shown varying degrees of success.
