A 31-year-old woman complained of a sudden, painless decrease in visio
n of the right eye. Ophthalmic examination demonstrated a vitreous hem
orrhage in the right eye secondary to peripheral neovascularization. T
he left eye demonstrated findings consistent with pars planitis. Befor
e this episode, vision was good in both eyes. Although rare, vitreous
hemorrhage can occur in the setting of pars planitis and may be a pres
enting symptom. Pars planitis should be considered in the differential
diagnosis of young patients with vitreous hemorrhage.
