Persistent corneal epithelial defects (PEDs) hinder healing after eye injury, risking vision loss. Prompt, multi-faceted treatment is crucial for effective PED management and preventing complications.

Area of Science:

  • Ophthalmology
  • Regenerative Medicine

Background:

  • Persistent corneal epithelial defects (PEDs) are a significant clinical challenge, often arising from impaired wound healing post-injury.
  • These defects compromise corneal integrity, increasing susceptibility to infection, ulceration, and vision impairment.

Purpose of the Study:

  • To review the epidemiology, etiology, diagnosis, and management of persistent corneal epithelial defects.
  • To discuss current and emerging therapeutic strategies for refractory PEDs.

Main Methods:

  • Literature review of studies on corneal epithelial defects.
  • Analysis of standard and novel treatment modalities for PEDs.
  • Discussion of diagnostic approaches and prognostic factors.

Main Results:

  • PEDs result from failed re-epithelialization within 10-14 days, requiring prompt intervention (7-10 days) to avoid complications.
  • Treatment involves addressing underlying causes (infection, stem cell deficiency, diabetes) and employing barrier protection (BCLs, ATs).
  • Novel therapies include growth factors, anti-inflammatory agents, and surgical re-innervation techniques.

Conclusions:

  • Effective management of PEDs necessitates a step-wise approach, addressing causative factors and utilizing advanced treatments for refractory cases.
  • Early diagnosis and intervention are key to improving outcomes and preventing severe visual consequences associated with PEDs.
