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 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

Surgical Indications AM

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

12
Pterygium

• A mutated growth on the surface of the eye
• Requires surgical excision and placement of graft

13
Corneal Ulcerations/perforations

• A break or defect in corneal epithelium
• Often secondary to other systemic diseases.

14
Chemical/thermal Burns

• Chemical burns often caused by alkali
• Potentially devastating trauma to surface of the
  eye
• Limbal graft possibly indicated

15
Bullous Keratopathy

• Edema of the corneal endothelium
• Very common and usually affects individuals over
  50 years of age.

16
Dermoid/tumor Removal

• Benign congenital tumors containing foreign
  tissue
• Commonly found at the limbus

17
Fornix 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
