Bimanual 25-gauge chandelier technique for direct perfluorocarbon liquid-silicone oil exchange in retinal detachments associated with giant retinal tear

Abstract

Direct perfluorocarbon liquid (PFCL)-silicone oil exchange presents its own set of challenges in the micro incision vitreous surgery era. We propose a simple bimanual technique to circumvent this problem. Thirteen eyes of patients with retinal detachment associated with giant retinal tears underwent vitrectomy followed by self-retaining endo illuminator (Chandelier) assisted direct PFCL-silicone exchange. No intra or postoperative complications related to the surgical technique were noted. All patients had attached retinas and satisfactory visual recovery at 6 months. Direct bimanual PFCL silicone oil exchange using a Chandelier seems to be a safe and effective technique.

“…4 In the conventional technique for direct PFCL-SO exchange, SO is actively injected with the foot pedal and PFCL is passively aspirated using a flute needle. 5,6 Because passive aspiration of fluids is inherently slow, the inflow of SO during the exchange often exceeds the passive outflow of PFCL. As a result, the vitreous cavity becomes over-pressurized and intraocular pressure (IOP) rises.…”

Hybrid 23/25-Gauge Direct Perfluorocarbon Liquid—Silicone Oil Exchange

“…This mainly stems from fear that in the conventional technique for the direct exchange, the active inflow of SO during the exchange exceeds the passive outflow of PFCL. 4,5 As a result, the vitreous cavity becomes over-pressurized and intraocular pressure (IOP) rises to a very high level. This may subsequently lead to significant intraoperative events such as corneal clouding, SO migration into the anterior chamber and may even result in a scleral rupture.…”

“…This may subsequently lead to significant intraoperative events such as corneal clouding, SO migration into the anterior chamber and may even result in a scleral rupture. 4 In this report, we describe a simple modification for direct PFCL-silicone exchange that minimizes the risk of significant intraocular pressure elevation at the time of surgery.…”
