Comparison of Topical Insulin and Amniotic Membrane Transplant for Persistent Corneal Epithelial Defects

April 28, 2026 updated by: Subha Masham, Al-Shifa Trust Eye Hospital

Comparison of Efficacy of Topical Insulin With Amniotic Membrane Transplant in Persistent Epithelial Defects of Cornea

After an initial period of standard treatment, they received further care aimed at helping the surface of the eye heal. Clear instructions were given on how to use and store the treatment properly. Patients were then monitored regularly over several months, with doctors checking their healing progress during follow-up visits. The study continued for a total of 24 weeks to observe how well and how quickly the eye surface recovered.

Study Overview

Detailed Description

The area of the corneal epithelial defects will be evaluated using anterior segment photography of the cornea which will be performed after administration of fluorescein dye at a magnification of 10× using a camera attached to a slit-lamp microscope. The images will be analyzed with an image analysis system (ImageJ software) by a single observer to determine the epithelial defect area. The corneal epithelial defect will be graded from I through III. The patients will be randomly divided into two groups using computer generated random number. One half will be treated with Amniotic membrane grafts while other half will receive treatment with topical insulin drops administered every 6 hours till complete re-epithelization of corneal epithelial defects. Follow up will be done uptil 24 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cure rate
Time Frame: From time of randomization up to 24th week of followup.
This will be the number of patients out of total number in each group completely cured of corneal epithelial defects
From time of randomization up to 24th week of followup.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean time to healing
Time Frame: From time of randomization upto 24th week of followup
This will be the mean time to complete healing in weeks from initiation of treatment until full epithelial closure as confirmed by lack of fluorescein staining on slit-lamp examination.
From time of randomization upto 24th week of followup
