What does membrane placement provide in corneal ulcer therapy?

• A. Support and healing proteins
• B. Permanent cure
• C. Immunosuppression
• D. Vitamin supplementation

Answer: (A)

Membrane placement in corneal ulcer therapy acts as a biological bandage that gives the healing process a solid scaffold. The amniotic membrane provides extracellular matrix components and healing proteins, including growth factors, that support epithelial cell adhesion, migration, and re-epithelialization. It also brings anti-inflammatory and anti-scarring factors that help control inflammation and reduce scar formation, promoting a clearer, smoother corneal surface. Additionally, it protects the surface from drying and mechanical irritation while healing occurs. This is not a permanent cure and it does not function as immunosuppression or vitamin supplementation—the main benefit is to support and enhance the eye’s own healing with healing proteins.
