Abstract #11756 Published in IGR 7-1
Migration of intravitreal silicone oil through a Baerveldt tube into the subconjunctival space
Friberg TR; Fanous MMSeminars in Ophthalmology 2004; 19: 107-108
A 28-year-old patient developed proliferative diabetic retinopathy with florid rubeosis iridis and ultimately required the placement of a Baerveldt tube to control his secondary glaucoma. Eighteen months later, he underwent a pars plana vitrectomy, scleral buckle, lensectomy, and membrane peeling to reattach a severe diabetic retinal detachment. Ultimately, some of the 5000 cs silicone oil migrated through the tube to the episcleral region under the plate of the Baerveldt device. The oil intermittently blocked the shunt, causing elevated intraocular pressure. Despite ultimate surgical removal of the oil from around the tube and plate, a substantial amount remained encapsulated in the subconjunctival space. Prevention of this complication includes placement of a short tube well anterior to the iris in the inferior portion of the anterior chamber.
