Light-Guided Transscleral Drainage of Subretinal Fluid

In this surgical video, Dr. Khalid Sabti performs transscleral drainage of subretinal fluid in a 14-year-old patient with Coats disease and progressive vision loss. After a pars plana vitrectomy, he bends a 27-gauge light pipe into a Z configuration. To that bent pipe, he attaches a needle that is connected to a viscous fluid extraction kit. After locating the drainage site, he inserts the syringe into the subretinal space and aspirates the fluid. The bevel of the needle should face the choroid to avoid puncturing the retina. Endolaser to abnormal vessels was performed to end the case; no anti-VEGF injection was given. The patient’s vision improved from 20/400 to 20/100 at the 4-month follow-up.
