Clinical study of vitreous surgery with direct central retinal artery massage for the treatment of central retinal artery occlusion

In patients with central retinal artery occlusion, is vitreous surgery with direct central retinal artery massage superior to traditional treatment in improving circulation

Sponsor

Beijing Tongren Eye Center

Enrollment

300 participants

Start Date

Jan 1, 2005

Study Type

Interventional

Conditions

central retinal artery occlusion

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.

Eligibility

Sex: Both males and females

Plain Language Summary

Simplified for easier understanding

This study is looking at a surgical treatment for a serious eye condition called central retinal artery occlusion — which is basically a 'stroke' in the eye that can cause sudden vision loss. The surgery involves gently massaging the blocked artery inside the eye to try to break up the blockage and restore blood flow and vision. You may be eligible if: - You have been diagnosed with central retinal artery occlusion within the last 4 days - You do not have other eye diseases that are affecting your vision You may NOT be eligible if: - Your eye blockage happened more than 4 days ago - You have other eye conditions that significantly affect your vision Talk to your doctor about whether this trial might be right for you.

This is a simplified summary. Always discuss eligibility with your doctor before enrolling in a clinical trial.

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).
