A Review of Limbal Stem Cell Deficiency

Abstract

Limbal stem cell deficiency (LSCD) can be secondary to multiple etiologies including contact lens wear, chemical or thermal trauma, and systemic disease, any of which can result in the reduction of the number of stem cells or their decreased functionality. Primary LSCD is seen with a variety of congenital anterior segment disorders. Often LSCD can be stabilized and timely diagnosis is the key. The use of topical corticosteroids and artificial tear lubricants, along with treatment of any underlying conditions, and discontinuation of contact lenses are important initial treatment strategies. Advance treatments include amniotic membranes, limbal stem cell transplantation and keratoprostheses.
