Amniotic Membrane Transplantation for Limbal Stem Cell Deficiency

Overview

The maintenance of a healthy functional corneal epithelium is provided by a unique subpopulation of stem cells located in the limbal region1. When limbal epithelial stem cells are destroyed or become dysfunctional, a pathological state known as limbal stem cell deficiency (LSCD) manifests. The hallmark of LSCD is the conjunctivalization of the cornea2, and is frequently associated with superficial vascularization and compromised corneal surface3.

LSCD can be found with a number of corneal diseases such as chemical burns, Stevens Johnson syndrome, aniridia, peripheral keratitis, severe limbitis, etc (for more details see Table 1). Patients with LSCD suffer from a severe loss of vision and annoying photophobia, and cannot be corrected by conventional PKP. Therefore, it is important to accurately diagnose LSCD because erroneous diagnosis may subject the patient to unnecessary surgeries. Correct diagnosis, which may require the use of impression cytology, will lead to reconstruction with limbal stem cell transplantation.
