The usefulness of diagnostic vitrectomy in patients with suspected sarcoidosis with posterior segment involvement (in whom a diagnosis cannot be determined by conventional methods) has not been well described. We hypothesized that diagnostic vitrectomy would help establish the diagnosis in these challenging cases. Herein, we evaluated the diagnostic yield of vitreous biopsy in patients with suspected sarcoidosis-associated uveitis that affected the posterior segment.This is a retrospective interventional case series. Cases of intermediate, posterior or panuveitis that could not be characterized by clinical examination, ancillary, and laboratory tests were considered for diagnostic pars plana vitrectomy. Retrospective chart review was conducted on consecutive eyes that underwent diagnostic, or diagnostic and therapeutic vitrectomy by a single surgeon from January 1989 to June 2006.

Patients with suspected sarcoid-related posterior segment inflammation with inconclusive clinical exam findings, ancillary testing, and laboratory results

Procedure: Diagnostic Vitrectomy
Three-port, 20-gauge pars plana vitrectomy instrumentation was utilized. An infusion line was inserted into one sclerotomy and secured to the globe. A second sclerotomy was made, and a fiberoptic light pipe was immediately inserted to minimize vitreous egress. A third sclerotomy was created, and the vitreous cutter was inserted. To obtain an undiluted vitreous sample, the vitreous was cut mechanically with the vitreous cutter, while the assistant surgeon simultaneously manually aspirated the vitreous. After sufficient undiluted sample was obtained, infusion fluid was allowed to enter the eye and a diluted vitreous sample was obtained in a similar manner. The samples were personally carried to the clinical laboratories by the operating surgeon. Vitreous fluid analysis was guided by clinical suspicion based on the pre-operative differential diagnosis and the intraoperative posterior segment appearance. |
