Clinical Trial Summary

EECP therapy may affect the intraocular pressure while improving the ischemia systemic organ blood perfusion the same time. The present study investigated the impact of Enhanced Extracorporeal Counterpulsation treatment on the intraocular pressure.

Description:

Select 40 cases of patients (80eyes) who had counter pulsation treatment at Enhanced External Counter Pulsation (EECP) Specialist in First Affiliated Hospital of Sun Yat-sen University during Apr 2012 - Mar 2013. Separated the patients into 2 groups according to having glaucoma history or not.The cases whose eyes have erythralgia and who have received corneal surgery or intraocular surgery in recent one month are excluded.
