Summary
Tissue-engineered epithelium transplantation effectively treated severe ocular surface burns. This procedure improved vision and reduced corneal neovascularization in most patients, promoting rapid ocular surface healing.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Biomaterials Science
Background:
- Severe ocular surface burns pose significant challenges to vision restoration.
- Current treatments may have limitations in promoting complete ocular surface healing and preventing complications.
Purpose of the Study:
- To evaluate the clinical outcomes of tissue-engineered epithelium transplantation for severe ocular surface burns.
- Assessing the efficacy of autologous corneal stem cell transplantation on a fibrin gel membrane.
Main Methods:
- Retrospective observational case series of 19 eyes with severe ocular surface burns (Dua Classification IV-VI).
- Autologous transplantation of corneal stem cells cultivated on a fibrin gel membrane.
- Evaluation of postoperative corneal surface stability, visual acuity, opacity, and neovascularization over a mean follow-up of 16.2 months.
Main Results:
- No corneal perforations occurred; complete epithelial defect closure in all eyes.
- Visual acuity improved in 17 eyes, with 6 achieving 20/100 or better.
- Significant reduction in corneal neovascularization (89.5%) and improvement in corneal opacity (63.2%) observed.
Conclusions:
- Tissue-engineered epithelium transplantation promotes rapid ocular surface reepithelialization.
- The procedure effectively inhibits corneal neovascularization and improves visual acuity in severe burns.
- Autologous transplantation of cultivated corneal stem cells offers a viable therapeutic option for severe ocular surface damage.

2.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:22Burn Injuries
4.4K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
