OCULAR VASOSPASM INDUCED BY COLD AND PRIM ARY VASCULAR ACROSYNDROMA

An ocular vasospasm induced by cold has been searched among 8 patients carrying primary vasospastic disease without any ocular pathology. Oc ular vasospasm which is caracterized by visual field defect was search ed with Statpac 24-2 test using HUMPHREY autoperimeter. A baseline vis ual field was performed first, then a second after provocation by dipp ing the hand in cold water (13-degrees) and a third after oral adminis tration of 10 mg of Nifedipine. Two patients had ocular vasospasm that regressed after Nifedipine administration. These two patients might h ave a higher risk to develop normal tension glaucoma.
