Cryotherapy of Sclerotomy Sites for Prevention of Late Postvitrectomy Diabetic Hemorrhage
Not Provided
Late vitreous hemorrhage in postvitrectomized diabetic eyes may be due to fibrovascular tuft formation in sclerotomy sites. Cryotherapy of sclerotomy sites may prevent bleeding by regressing the fibrovascular tuft. This study will detect the safety and efficacy of cryotherapy of sclerotomy sites for prevention of late vitreous hemorrhage in vitrectomized diabetic eyes.
