Details and patient eligibility

About

The goal of this clinical trial is to evaluate the preliminary efficacy of the use of insulin eye drops in the control of dry eye disease in patients with topical hypotensors, compared to placebo (artificial tears).

The main question aims to answer whether glaucoma patients treated with topical hypotensors could benefit from the use of insulin eye drops for the treatment of dry eye.

Participants will be assigned to one of the two treatment arms and will be required to attend four follow-up visits (baseline, 1, 3, and 6 months).

Full description

Patients will be recruited in Madrid. Patients with dry eye disease and topical glaucoma treatment will be identified through the Ophthalmology clinic. They will be directly referred to a physician who is participating in this study.
