SPONTANEOUS CLOSURE OF MACULAR HOLE AFTER DRAINAGE OF SUBFOVEAL PERFLUOROCARBON LIQUID.

Objective: To report a rare case of macular hole formation after drainage of subretinal perfluorocarbon liquid (PFCL), which closed spontaneously.

Methods: Retrospective case report. A 60-year-old was noted to have subfoveal PFCL after a macula-involving retinal detachment repair with silicone oil tamponade. Spectral domain optical coherence tomography (Spectralis; Heidelberg Engineering, Heidelberg, Germany) was used for postoperative imaging.

Results: Two months postdetachment repair, the patient underwent removal of silicone oil and drainage of subfoveal PFCL using a 41-gauge cannula through a extrafoveal retinotomy. A full-thickness macular hole was noted 2 weeks postoperatively. This closed spontaneously 4 months later, with an improvement in vision, although there was evidence of subfoveal atrophy.

Conclusions: Macular hole formation can occur after drainage of subfoveal PFCL, with a favorable prognosis if managed conservatively. The resultant foveal atrophy highlights the importance of early identification and removal of subretinal PFCL.
