[Is atropine efficient in para-bulbar injections?]

Supposing the fact that atropine has antispastic effect on blood vessels, we studied the variation of blood flow in ophthalmic artery, central retinal artery and ciliary arteries, by Doppler ultrasound. We used 1 ml Atropine 1@1000 in parabulbar administration to 17 eyes with neuro-retinal diseases and the arterial flow was registered for 3 times: before the injection, at 15 and respective 30 minutes after administration. The results were processed using t-Student method. The atropine effect seemed to be more intensive 30 minutes after administration on central retinal artery.
