Long-term results of pars plana vitrectomy in the management of intermediate uveitis.

Pars plana vitrectomy is a useful tool for the management of certain complications in chronic intermediate uveitis. Media opacities obscuring the visual axis, vitreous membranes causing tractional retinal detachment, macular puckers, and ciliary traction leading to hypotony are clear indications for this approach. Furthermore, it has been suggested that vitrectomy may have a favorable long-term effect on the course of disease. The procedure may achieve regression of inflammation, tapering of immunosuppression, and improvement of cystoid macular edema. However, randomized prospective trials are still needed to define the role of vitrectomy in altering the course of uveitis.
