[Change of plasma endothelin-1 concentrations in photodynamic induced rat anterior ischemic optic neuropathy model and drug modulation].

Objective: To investigate changes of plasma endothelin-1 (ET-1) concentration in photodynamic induced rat anterior ischemic optic neuropathy model (rAION) and evaluate the effects of compound anisodine hydrobromide (CA).

Methods: Eighty-five Sprague-Dawley (SD) male rats were randomly divided into a blank control group of 10 rats and a model group of 75 rats. rAION model was established in the model group by photodynamic induction.
