Summary
The purpose of the study is to evaluate the effect and safty of vitreous surgery with direct central retinal artery massage for central retinal artery occlusion. Pressing the central retinal artery in the optic nerve head with a probe or retrobulbarly with a sclera depressor led to deformation and bending of the blood vessel wall. During the mechanical movement of the vessels induced by the probe, the embolus may be broken into smaller pieces and then be dislodged, followed by curculation recovery. More than 15 cases received the sugical treatment, and more than 100 patients received the traditional treatments.

Interventions
After standard 3 port pars plana vitrectomy(PPV),a probe specialy desinged for the surgery was used to penitrate into the optic nerve head along the central retinal artery, at the same time, diretcly massaging along the central retinal artery wall (5-6 times, about 3 minutes).If the circulation did not recover, then a scleral depressor was used to press the optic nerve slightly retrobulbarly 5-6 times (about 2 minutes).
