Abstract

Insights

Perfluorocarbon liquid injection during retinal detachment surgery can cause macular holes. Careful technique is crucial to prevent this rare complication and ensure successful patient outcomes.

Area of Science:

  • Ophthalmology
  • Vitreoretinal Surgery

Background:

  • Perfluorocarbon liquids (PFCLs) are vital in managing retinal detachment (RD).
  • Unique risks exist, including subretinal migration.
  • Macular hole (MH) formation during PFCL injection is an underreported complication.

Observation:

  • A localized retinal dimpling occurred during PFCL jet stream injection in a rhegmatogenous RD case.
  • This dimpling was immediately followed by MH formation and subretinal PFCL migration.
  • Internal limiting membrane peeling and PFCL mobilization were performed.

Findings:

  • The case demonstrates a novel complication of PFCL injection: induced macular hole.
  • Successful management involved surgical intervention to close the MH and remove subretinal PFCL.
  • Post-operative OCT confirmed MH closure and vision improvement.

Implications:

  • Highlights the need for meticulous PFCL injection techniques to avoid iatrogenic trauma.
  • Emphasizes understanding the mechanism of PFCL-induced MH for improved surgical strategies.
  • Underscores the importance of prompt management of PFCL-related complications in retinal surgery.
