Expression of Matrix Metalloproteinase-9, Transforming Growth Factor Beta and Fibroblast in The Simblefaron Due to Alkali Burn: Literature Review

Abstract

Simblefaron is one of the most challenging complications in the late stages of an alkali burn. Symblepharon characteristically resembles connective tissue or bands that protrude from the eyelid's interior surface (palpebral conjunctiva) to the surface of the eyeball (bulbar conjunctiva). This literature review was conducted to see the molecular mechanism of symblepharon formation. Matrix metalloproteinase (MMP- 9), transforming growth factor (TGF-β), and Fibroblast played a significant part in the healing of conjunctival wounds. MMP-9, TGF-β, and fibroblast overexpressed are suspected to cause excessive inflammation and fibrosis, which results in symblepharon. By knowing this, it is hoped that it can become a basis for developing appropriate management for the occurrence of simblepharon. Keywords: Symblepharon, Alkali, Burn, Conjunctiva.
