  1. What is Persistent Corneal Epithelial Defects? By- DelveInsight Business Research

  2. What is Persistent Corneal Epithelial Defects? Persistent Corneal Epithelial Defects are a focal area of epithelial (outermost corneal layer) loss; can be due to mechanical trauma, corneal dryness, neurotrophic cornea, post‐surgical changes or any other variety of etiologies. Corneal epithelial defects are one of the most commonly seen ocular pathologies in the general patient population. Healthy corneal epithelium is essential in protecting the eye against infection and structural damage to deeper tissues.

  3. A non‐healing, or persistent, epithelial defect occurs when there is a failure of the mechanisms promoting corneal epithelialization within the normal 2‐week time frame. In addition to causing compromised vision and ocular discomfort, non‐healing corneal epithelial defects have other deleterious consequences, including infection, scarring, melting, and perforation.

  4. The conditions that most commonly lead to a persistent epithelial defect fall into four major categories, namely, epithelial/limbal stem cell deficiency, inflammatory disease, neurotrophic disease, and mechanical factors.

  5. The symptoms include pain, tearing and foreign body sensation of the affected eye (the exception being neurotrophickeratopathy) which are commonly alleviated by the instillation of topical anaesthetic. They can also be accompanied by photophobia, pain with blinking and eye movement.

  6. Persistent corneal epithelial defects (PEDs or PCEDs) result from the failure of rapid re‐epithelialization and closure within 10‐14 days after a corneal injury, even with standard supportive treatment. Disruptions in the protective epithelial and stromal layers of the cornea can render the eye susceptible to infection, stromal ulceration, perforation, scarring, and significant vision loss.
