9 Uveitis and Ocular Inflammation
Chapter 14: Complications of Uveitis
Vitreous Opacification and Vitritis
Vitreous membranes in chronic cases not responding to steroid treatment to a degree that vision is affected may occur in uveitis. Vitrectomy in eyes with quiet inflammation may improve visual acuity in these cases, with 1 review of studies on pars plana vitrectomy in uveitis showing visual acuity improved in 68%. A standard small (25- or 23-gauge) 3-port pars plana vitrectomy is the preferred technique, with a few minor variations (see BCSC Section 12, Retina and Vitreous).
