Previous pilot study has demonstrated that the novel multi-endodiathermy retinectomy is feasible, effective and safe for inferior retinal redetachments in the silicone oil-filled eyes of adults over a 3-month observation.

Here, the investigators conduct this randomized and multicenter clinical trial to compare the efficacy and safety between multi-endodiathermy retinectomy and relaxing retinectomy.

The relaxing retinectomy is a useful surgery for retinal re-detachment in eyes with silicone oil filled. However, it has some obvious disadvantages such as the cut of the normal retina surrounding, leaving a large area of retinal deficiency and significant exposure of retinal pigment epithelium and choroid membranes.

We proposed a novel multi-endodiathermy retinectomy as a potential surgery. A pilot study has demonstrated that the novel multi-endodiathermy retinectomy is feasible, effective and safe for inferior retinal redetachments in the silicone oil-filled eyes of adults over a 3-month observation.

Here, the investigators conduct this randomized and multicenter clinical trial to compare the efficacy and safety between multi-endodiathermy retinectomy and relaxing retinectomy.

Inclusion Criteria:

• Age 18-60 years, male or female;
• The primary retinal detachment was caused by ocular trauma, and the vitreous body is filled with silicone oil now;
• The presence of inferior retinal re-detachment located among 3-9 o'clock.

Exclusion Criteria:

• Location of the re-detached retina is not mainly in the inferior of the eye;
• The fundus is unobservable because of severe corneal opacity;
• The contralateral eye is non-functional;
• Serious heart, lung, liver and kidney dysfunction.
