EFFECTS OF INFLAMMATION ON PROGNOSIS FOLLOWING VITRECTOMY / 解放军医学杂志

ABSTRACT

Vitrectomy is helpful in the management of ocular trauma,but prolonged inflammation following vitrec tomy may be associated with a high incidence of traction retinal detachment. To test this hypothesis! ma-crophages.the main cellular component of vitreous inflammation,were injected into the vitreous cavity of rabbit eyes following vitrectorny. Fibrovascular proliferation over the medullary rays and optic disc and traction retinal detachment occurred in 13 of 15 vitrectomized eyes injected with macrophages,while in only three of 15 vitrectomized eyes injected with culture medium (controls). These results demonstrate that macrophages are capable of stimulating intraocular cellular proliferation. It is therefore suggested that anti-inflammation drugs and minimization of surgical intervention may improve the prognosis following vitrectomy.
