Abstract Details


Pneumatic retinopexy is a procedure that follows particular indications for rhegmatogenous retinal detachment management and requires a surgeon highly skilled at retinal examination. Surgeons must be able to manage postoperative care and complications associated with this procedure. Our video shows a case of complicated retinopexy with C3F8.

52-year-old woman, myopic, phakic, with a history of left eye (OS) macula-on superior rhegmatogenous retinal detachment treated with C3F8 retinopexy two weeks before. Presented to our department with a decreased visual acuity (BCVA 20/50, on Snellen scale). Fundus examination revealed a complicated macula-off retinal detachment with a subretinal C3F8 gas bubble. A 23-gauge pars plana vitrectomy was performed.


Intraoperative findings as difficult gas extraction and manipulation were observed and had to be addressed. Six months after the surgery the retina is attached with 20/25 BCVA on Snellen Scale.


Failure of pneumatic retinopexy is thought to be due to the posterior position and dimension of the original break, or to missed or new tears. In this video we address some of the specific features associated with the presence of subretinal gas when repairing a retinal detachment due to a failed pneumatic retinopexy.
