# Subfoveal perfluorocarbon liquid removal by peeling of internal limiting membrane, without retinotomy

## TL;DR

A 43-year-old woman had subfoveal perfluorocarbon liquid removed without retinotomy by peeling the internal limiting membrane.

## Contribution

A novel method for removing subfoveal perfluorocarbon liquid without retinotomy is described.

## Key findings

- Subfoveal perfluorocarbon liquid can be removed using internal limiting membrane peeling.
- The procedure avoided retinotomy and preserved retinal structure.
- The method offers a potential alternative for treating subretinal retention.

## Abstract

Perfluorocarbon liquid has been widely used during vitreoretinal operations.
Subretinal retention is a rare intraoperative complication, but even small
quantities can damage the macular structure and function, and no standard
treatment has been established. We encountered a 43-year-old woman who presented
a retained subfoveal bubble after a vitreoretinal operation due to primary
rhegmatogenous retinal detachment. Herein, we describe the procedure we used to
remove the perfluorocarbon liquid without retinotomy using internal limiting
membrane peeling.
