Surgical management of premacular fibroplasia.

The results of pars plana vitrectomy and membrane peeling for premacular fibroplasia (PMF) were reviewed retrospectively for 88 eyes of 86 patients. Premacular fibroplasia was idiopathic in 61 eyes (69%) and postdetachment in 27 eyes (31%). All patients had a minimum follow-up of 12 months. Visual symptoms of blurring and metamorphopsia were reduced in 75 (85%) study eyes at the end of the follow-up period. Poor visual outcome was significantly related to preoperative cystoid macular edema and prolonged duration of visual blurring. Posterior retinal breaks occurred in three eyes (5%) with idiopathic PMF and five eyes (19%) with postdetachment PMF. Cataract progression was demonstrated in 35 eyes (48%) at 12 months of follow-up and 49 eyes (68%) at 24 months of follow-up, reflecting an incidence of cataract formation that has not been previously reported (to our knowledge) after limited vitrectomy and membrane peeling for PMF.
