Abstract
Purpose:To report the anatomical and visual outcomes of double layered amniotic membrane transplantation (AMT) in eyes with advanced Pseudomonas keratitis leading to Descemetocele formation.Methods:This prospective interventional case series included 6 eyes of 6 female patients with pseudomonas keratitis caused by contact lens-induced infection who underwent double layered AMT. Surgery was performed after the ulcers were found to be poorly responsive to antibiotics, and severe thinning or Descemetocele had developed. All patients underwent a complete examination pre- and postoperatively, as well as anterior segment optical coherence tomography (OCT) and pachymetry or Orbscan after the procedure.Results:Mean follow-up period was 24 months. There was neither frank corneal perforation nor a need for emergent corneal transplantation in any of the eyes. All patients had visual acuity of hand motions before the procedure which improved to 20/50 to 20/30 three months after surgery. No surgical or postoperative complication occurred in this series.Conclusion:Double layered AMT may result in acceptable anatomical outcomes in patients with advanced Pseudomonas keratitis with Descemetocele formation and can eliminate the need for emergent corneal transplantation.
Highlights
We report the results of amniotic membrane transplantation (AMT) on 6 eyes of 6 patients referred to Farabi Hospital, Tehran University of Medical Sciences, Tehran, Iran
No surgical or postoperative complication occurred in this study [Table 1]. This 21‐year‐old female subject was hospitalized for pseudomonas keratitis
AMT is beneficial for preventing corneal perforation caused by corneal thinning and melting in Pseudomonas keratitis.[2]
Summary
Interventions used for descemetoceles, including tissue adhesives and glues, bandage contact lenses, and lamellar or penetrating keratoplasty, are not effective in approximately half of such cases.[3] Amniotic membrane.
