Amniotic Membrane in Ophthalmology

The amniotic membrane is the inner most layer of the three fetal membranes lying deep to chorion. It is translucent and avascular in nature. It is derived from fetal ectoderm by cavitation within the fetal knot. It is composed of three layers: epithelium, basement membrane and stromal [1]. The structural integrity, transparency and elasticity makes the amniotic membrane most widely accepted tissue for ocular surface reconstruction.
