Summary

Retained submacular perfluorocarbon liquid (PFCL) can be stable long-term. Surgical removal may improve vision in select cases with significant visual loss.

Area of Science:

Ophthalmology
Retinal Surgery
Vitreoretinal Interface

Background:

Perfluorocarbon liquids (PFCLs) are used in complex retinal detachment repair.
Retained submacular PFCL can occur postoperatively.
Understanding outcomes of retained submacular PFCL is crucial.

Observation:

A retrospective case series reviewed 8 eyes with retained submacular PFCL.
Most cases involved observation without surgery (7/8 eyes).
One eye underwent surgical PFCL removal due to juxtafoveal location and macular edema.

Findings:

Submacular PFCL remained stable in 7 eyes for up to 9 years (mean 4.4 years).
Visual acuity improved or remained stable in all observed eyes.
Surgical removal in one eye led to improved visual acuity (20/200 to 20/125) and reduced macular edema.

Implications:

Submacular PFCL may not necessitate immediate intervention and can be stable.
Surgical PFCL removal is a viable option for patients experiencing significant visual impairment.
Further research can optimize management strategies for retained submacular PFCL.
