What Is Human Amniotic Membrane?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.

History of AM in OphthalmologyHistory 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 80’s USSR->Venezuela, DR]

• Batlle and Perdomo. Conjunctival substitute with placental allotransplant. Scientific Poster 25. American Academy of Ophthalmology meeting. Chicago, IL USA. October 1993.

Surgical Indications: AMSurgical Indications: AM

• Pterygium Excision• Corneal Ulcerations/Perforations• Chemical/Thermal Burns• Bullous Keratopathy• Ocular Dermoids/Tumors• Fornix Reconstruction/Symblepharon• Stem Cell Transplants

PterygiumPterygium

• A mutated growth on the surface of the eye

• Requires surgical excision and placement of graft

Corneal Ulcerations/perforationsCorneal Ulcerations/perforations

• A break or defect in corneal epithelium

• Often secondary to other systemic diseases.

Chemical/thermal BurnsChemical/thermal Burns

• Chemical burns often caused by alkali

• Potentially devastating trauma to surface of the eye

• Limbal graft possibly indicated

Bullous KeratopathyBullous Keratopathy

• Edema of the corneal endothelium

• Very common and usually affects individuals over 50 years of age.

Dermoid/tumor RemovalDermoid/tumor Removal

• Benign congenital tumors containing foreign tissue

• Commonly found at the limbus

Fornix ReconstructionFornix 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
