Official title
Ensayo Clínico Para Determinar La Eficacia Y Seguridad Del Colirio De Insulina En El Tratamiento Del Ojo Seco En Pacientes Con Hipotensores Tópicos
Overview
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).
Detailed 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.
Interventions
- Drug Insulin
Topical insulin 1UI/ml 4 times a day - Drug Artificial tear
Artificial tears 4 times a day
Primary outcome measures
- Changes in dry eye symptoms from baseline to 6 months after treatment time [Time frame: From baseline to 6 months after treatment]
Secondary outcome measures (7)
- Change of corneal staining from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in corneal aesthesiometry from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in conjunctival hyperemia from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in non-invasive tear film break-up time from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in light dispersion from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in cytokine levels from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
- Change in therapeutic compliance from baseline to 6 months after treatment [Time frame: From baseline to 6 months after treatment]
