7 What is Human Amniotic Membrane?
- A unique, avascular membrane separating the
mother from the fetus. - Provides an incubating environment promoting
cellular differentiation. - Provides an immunological barrier to prevent
foreign body rejection.

8 Anatomical Profile AM
9 Anatomy of the Ocular Surface
(1) Conjunctival Epithelium (2) Corneal
Epithelium (6) Limbus Stem Cells
10 History of AM in Ophthalmology
- De Rotth. conjunctival defects (1940).
- Lavery. lime burn of conjunctiva and cornea
(1946). - Sorsby et al. caustic soda burns (1947).
- ALLOTRANSPLANTAT late 80s USSR-gtVenezuela, DR
- Batlle and Perdomo. Conjunctival substitute with
placental allotransplant. Scientific Poster 25.
American Academy of Ophthalmology meeting.
Chicago, IL USA. October 1993. - Kim and Tseng. Transplantation of preserved human
amniotic membrane for surface reconstruction in
severely damaged rabbit corneas. Cornea
14473-84, 1995.
11Surgical Indications AM
- Pterygium Excision
- Corneal Ulcerations/Perforations
- Chemical/Thermal Burns
- Bullous Keratopathy
- Ocular Dermoids/Tumors
- Fornix Reconstruction/Symblepharon
- Stem Cell Transplants
12Pterygium
- A mutated growth on the surface of the eye
- Requires surgical excision and placement of graft
13Corneal Ulcerations/Perforations
- A break or defect in corneal epithelium
- Often secondary to other systemic diseases.
14Chemical/Thermal Burns
- Chemical burns often caused by alkali
- Potentially devastating trauma to surface of the
eye - Limbal graft possibly indicated
15Bullous Keratopathy
- Edema of the corneal endothelium
- Very common and usually affects individuals over
50 years of age.
16Dermoid/Tumor Removal
- Benign congenital tumors containing foreign
tissue - Commonly found at the limbus
17Fornix Reconstruction
- Fibrous tract that connects bulbar conj to conj
of eyelid - Secondary to other acquired or traumatic
conditions - Required reconstruction of ocular surface and
eyelids
18Surgical Techniques AMT/Pterygium
