Topical Insulin in Neurotrophic Keratopathy After Diabetic Vitrectomy
Egypt30 participantsStarted 2023-07-15
Plain-language summary
Various treatment options have been proposed in managing NK such as preservative-free lubrication (PF-L), withdrawal of epitheliotoxic medication, prophylactic antibiotics, applying of bandage contact lenses, using hemoderivatives 8, topical insulin, recombinant nerve growth factor (rNGF) or epidermal growth factor (rEGF).11,12, amniotic membrane transplant (AMT), or corneal neurotization.2,4,9,10 Topical insulin has been reported to effectively promote the healing of persistent corneal epithelial defects.
In our retrospective study, we explored the safety and efficacy of topical insulin, as a first-line treatment, in treatment-naïve acute NK after diabetic vitrectomy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult diabetic patients (18 years of age) with neurotrophic keratopathy developing within 21 days after diabetic vitrectomy. NK was classified as stage 1 (epithelial changes only without epithelial defect), stage 2 (persistent epithelial defect) or stage 3 (corneal ulcer) according to published criteria.
* decreased corneal sensitivity within the corneal lesion and in at least 1 corneal quadrant outside the lesion.
Exclusion Criteria:
* Those patients who needed intraoperative epithelial debridement during vitrectomy, having past history of ocular surgeries other than cataract surgery, or history of herpetic eye disease or limbal stem cell deficiency were excluded.
* active ocular infection or inflammation unrelated to neurotrophic keratopathy, lagophthalmos, and other ocular disease or severe vision loss in the affected eye(s).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
