Brief Summary

Corneal infection or infectious keratitis (IK) is the most common cause of corneal blindness worldwide, particu-larly in the developing countries1. The incidence was estimated at 2.5-799 per 100,000 population/year. It is a painful and potentially blinding ocular emergency that often requires hospital admission for intensive medical and/or surgical treatment. Depending on the geographical and temporal variations and population-based risk factors (e.g. agricultural practice, trauma, use of contact lens and others), bacteria and fungi have been shown to be the main causative microorganisms for IK, followed by viruses, parasites and polymicrobial infection. Amniotic membrane (AM) is the innermost layer of the placenta, which consists of a single layer of meta-bolically active epithelium, a thick basement membrane, and an avascular stromal matrix (15).

It has been shown to exhibit a wide array of biological properties, including wound healing, anti-inflammatory, antimicrobial, and anti-angiogenic properties, amongst others. To date, a number of studies have evaluated the benefit of AMT for treating active IK, though the majority of them were of small case series or case reports. In clinical practice, AMT is usually reserved as a second-line therapy in IK, mainly to promote cornea healing in non-healing ulcer after the sterilization phase.
