[Microvitreous surgery combined with scleral encircling for the treatment of complex retinal detachments].

50 cases (50 eyes) of various complex retinal detachments (RD) were treated with a combination of vitrectomy, membrane peeling, intraocular air tamponade and scleral encircling. RD with opaque media, RD with proliferative vitroretinopathy, traction RD due to trauma or other factors, RD with posterior breaks, and giant tears were included. During the follow-up periods of 3-12 months, 27 cases (54%) obtained anatomic reattachment, 23 failed (46%). Of the successful case, 24 eyes achieved improvement, 2 eyes remained unchanged, and one eye became worse in their vision. The surgery complications were: retinal haemorrhage, choroidal haemorrhage, iatrogenic tears, and the development of cataract.
