title: Atypical reginal vasculitis associated with ticlopidine hydrochloridine use.
abstract: OBJECTIVE
  To describe two cases of retinal vasculitis shortly after the initiation of ticlopidine hydrochloride (Ticlid, Roche, Kingsland St, NJ) therapy.
  
  
  METHODS
  Case reports of two patients. The first patient was a 43-year-old white woman complaining of spots, floaters, and flashes of lights in both eyes 3 weeks after the initiation of treatment with ticlopidine hydrochloride. The second patient was a 72-year-old woman complaining of decreased visual acuity in the left eye for 2 weeks, 4 weeks after initiating oral administration of ticlopidine hydrochloride.
  
  
  RESULTS
  Both patients had resolution of the vasculitis after the discontinuation of ticlopidine therapy.
  
  
  CONCLUSIONS
  The temporal relation and the resolution of symptoms after discontinuation of ticlopidine hydrochloride suggest that the vasculitis was related to the ticlopidine hydrochloride administration. Knowledge of this potential complication of ticlopidine hydrochloride is important for the early diagnosis of this possible drug-induced side effect and the cessation of ticlopidine hydrochloride.
