Study Summary

This trial will test the efficacy of topical insulin in the treatment of corneal nerve damage, which can lead to a variety of complications including pain, discomfort, and blurry vision.

Who is the study for?
This trial is for adults over 18 with neurotrophic keratitis, a condition where the cornea loses sensation and doesn't heal properly. Participants must have tried other treatments without success and be able to consent to using topical insulin drops.Check my eligibility
What is being tested?
The study tests if topical insulin can help heal the cornea in patients with neurotrophic keratopathy who haven't responded to standard care. It compares this new approach against more invasive procedures like tarsorrhaphy (partially sewing eyelids together).See study design
What are the potential side effects?
Topical insulin might cause eye irritation, discomfort, or allergic reactions. Tarsorrhaphy may lead to altered eyelid appearance, infection at the stitch site, or difficulty fully closing the eyes.

Topical insulin (Humulin R) will be compounded under sterile conditions at a local pharmacy at a concentration of 25 IU / ml in sterile balanced saline solution (0.9%). Topical insulin will be administered four times per day to the affected eye. A bottle of topical insulin can be used for 14 days. Any remaining topical insulin will be discarded as waste after 14 days.
Group II: TarsorrhaphyActive Control1 Intervention
Patients in this group will receive a temporary, central tarsorrhaphy and will not use additional eye drops.
