Abstract
The visual results and complications were determined for a modified en bloc excision technique for management of diabetic traction macular detachment. A consecutive series of 30 eyes with this condition underwent pars plana vitrectomy, during which all posterior hyaloid except for portions essential for membrane dissection were excised. Bimanual dissection techniques then allowed excision of fibrovascular membranes "en bloc" with the retained hyaloid. After 6 to 44 months of follow-up, visual acuity of 5/200 or better was obtained in 23 (77%) of 30 eyes, with complete reattachment in 29 (97%) of 30 eyes. Iatrogenic retinal breaks occurred in 6 (20%) of 30 eyes. Two eyes required repeat vitrectomy. The modified en bloc excision technique allowed similar visual outcome, a higher reattachment rate, and less postoperative morbidity than previously reported surgical approaches to diabetic traction macular detachment.
