Carotid artery surgery improves ocular blood flow in OIS

Carotid artery surgery significantly improves ocular blood flow in patients with acute and chronic forms of ocular ishaemic syndrome (OIS), claims a study in Eye.

Dr V. V. Neroev et al., The Helmholtz Moscow Research Institute of Eye Diseases, Moscow, Russia, conducted a study on 180 patients with OIS. Of the participants, 104 had acute forms of OIS and 76 had chronic OIS.

All patients were assessed preoperatively and six and twelve months postoperatively. The outcome measures included visual acuity, electrophysiological investigations (the threshold of electrical sensitivity (TES) and the level of liability of optic nerve (LON)) and blood flow in orbital vessels.

TES and LON improved postoperatively and visual acuity increased in patients with acute OIS. At six and twelve months postoperatively, the mean indices of blood-flow velocities in the ophthalmic artery, the central retinal artery and the posterior ciliary arteries increased.
