Although the role of vitamin A deficiency in the development of xerophthalmia is well established, there is still some question as to whether the deficiency alone is sufficient cause for the development of keratomalacia. This article describes the clinical, histologic, and microbiologic changes
OBJECTIVE
To report in vivo reconstruction of the ocular surface using amniotic membrane and heterologous transplants of epithelial limbal cells in rabbits with chemical burns.
METHODS
After severe damage to the ocular surface with n-heptanol and keratectomy, 15 rabbits developed total limbal
Human amniotic membrane isolated from the placenta contained basement membrane components such as type IV collagen, laminin, and 6 and 4 integrins, all of which remained detectable while preserved in glycerin for one week. One month after the n-heptanol removal of the total corneal epithelium and
After n-heptanol removal of the total corneal epithelium and a limbal lamellar keratectomy, 23 rabbit eyes developed features of limbal stem cell deficiency including conjunctival epithelial ingrowth, vascularization and chronic inflammation. One month later, 10 control eyes received a total
