Area of Science:

  • Ophthalmology
  • Regenerative Medicine
  • Corneal Disease Treatment

Background:

  • Persistent epithelial defects (PED) pose a significant challenge in ophthalmology, often resistant to conventional treatments.
  • Limbal stem cell deficiency, neurotrophic cornea, and post-surgical complications are common causes of refractory PED.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of using a sutureless dehydrated amniotic membrane for treating persistent epithelial defects (PED).

Main Methods:

  • Retrospective analysis of patients with PED (≥14 days) treated with sutureless dehydrated amniotic membrane and bandage contact lens (BCL).
  • Patients with epithelial defects unresponsive to BCL treatment were included; those with <3 months follow-up were excluded.

Main Results:

  • Eighty-nine percent (8/9 eyes) of patients achieved PED resolution within 17.8 days without additional interventions.
  • LogMAR Best Corrected Visual Acuity (BCVA) significantly improved from 0.94 to 0.37 (p=0.036).
  • No complications or recurrences were recorded during the follow-up period.

Conclusions:

  • Sutureless dehydrated amniotic membrane is a highly effective treatment for PEDs arising from diverse etiologies.
  • This regenerative approach offers significant visual improvement and a favorable safety profile.
  • Further investigation is warranted to ascertain the long-term safety and efficacy of this treatment modality.
