Summary
This summary is machine-generated.

Retained subretinal perfluorocarbon liquid (PFCL) after eye surgery causes localized vision loss. Prompt removal of PFCL, especially near the fovea, is recommended to potentially restore retinal function.

Area of Science:

  • Ophthalmology
  • Retinal Surgery
  • Visual Physiology

Background:

  • Perfluorocarbon liquids (PFCLs) are used in complex vitreoretinal surgeries.
  • Retained subretinal PFCL can occur after these procedures.
  • The impact of subretinal PFCL on retinal function requires investigation.

Observation:

  • Microperimetry was conducted on four eyes with retained subretinal PFCL.
  • Scanning laser ophthalmoscopy assessed visual function in affected areas.
  • The study evaluated eyes following surgery for complicated retinal detachments.

Findings:

  • All tested eyes exhibited scotomas corresponding to the location of subretinal PFCL.
  • Scotomas were present even with the highest intensity stimuli.
  • Partial visual recovery was observed in one eye after PFCL migration.

Implications:

  • Retained subretinal PFCL leads to a measurable reduction in local retinal function.
  • Early detection and management of subretinal PFCL are crucial.
  • Consider surgical removal of PFCL if located beneath or at risk of migrating under the fovea.
