Summary

Integrity of the corneal epithelium is the function of intact limbal stem cells. The reduction in the population of LSCs and their dysfunction result in abnormal corneal epithelialization and invasion of the corneal surface by the conjunctival epithelium with or without corneal neovascularization that is, limbal stem cell deficiency (LSCD). Different techniques have been developed to treat cases of limbal stem cell deficiency due to traumatic or congenital cases. Recent innovations developed to predict the early stages of stem cell deficiency. One of these methods is measurement of the central epithelial thickness as it was found that limbal stem cell deficiency causes reduction of the central epithelial thickness.

The aim of this study is to study changes in the corneal epithelial thickness at different quadrants of the cornea to observe the exact time of epithelial stability following stem cell transplantation.

Conditions

  • Stem Cell Transplantation

Interventions

PROCEDURE

conjunctival limbal autologous transplant

Patients with unilateral chemical ocular injury will be included in the study. All selected patients will receive a thorough explanation of the study design and aims and informed consent will be obtained in all patients. Eyes of all participants will be subjected to: Best corrected visual acuity, Slit lamp examination and ocular ultrasound if no fundus view. Staging of degree of limbal stem cell deficiency is done by Roper Hall classification and then the patient will have conjunctival limbal autologous transplant (CLAU)
