Surgical Removal of Retained Subfoveal Perfluorocarbon Liquid through a Therapeutic Macular Hole with Intravitreal PFCL Injection and Gas Tamponade
A 67-year-old woman with loss of visual acuity in the left eye for 2 days was referred to our hospital. Best-corrected visual acuity (BCVA) in the left eye was hand motion. Fundus examination revealed a supero-temporal bullous macula-off retinal detachment with one peripheral retinal tear at the 3-o'clock direction. The patient underwent 23-gauge pars plana vitrectomy assisted by PFCL (perfluoro-n-octane; Alcon, Fort Worth, TX, USA) injection, laser treatment around the retinal tear and peripheral lattice degeneration, and PFCL-air exchange, followed by silicone oil injection. Two days later, subfoveal PFCL retention was noticed by funduscopy and optical coherence tomography (OCT) (). It is of note that the retina overlying the PFCL was extremely thin.
