Clinical trial of cultivated autologous oral mucosal epithelial cell sheet transplantation for corneal epithelial stem cell deficiency
Cultivated oral mucosal epithelial cell sheet transplantation
Japan |
Bilateral corneal epithelial stem cell deficiency: Patients with severe intractable ocular surface disease who have dysfunction of the entire limbus with totally replaced by conjunctival epithelium, neovascularization and corneal scarring tissue. (*Corneal epithelial stem cell deficiency: It is possible to make the diagnosis by using slit lamp microscopy showing loss of the palisades of Vogt (POV) and a conjunctivalized corneal surface which also can be seen by characteristic fluorescein staining patterns easily.)

To evaluate the efficacy and safety of cultivated autologous oral mucosal epithelial cell sheet transplantation.
Safety,Efficacy
To evaluate a size of epithelial defect and conjunctivalized corneal surface area in first postoperative year.
1. Improved visual acuity
2. Improved corneal opacity
3. Improved corneal neovascularization
4. Expected eye complications
5. All adverse events

Medicine | Maneuver |
Harvest of the oral mucosal tissue is conducted at the operation room in Ehime University Hospital. The tissue is transferred to Osaka University Hospital, and oral mucosal cell sheets are produced. The produced sheets are transferred back to the Ehime University Hospital, and transplanted to the cornea defected corneal epithelial stem-cell; then graft survival and stabilization of epithelial cells are attained.
