TUESDAY, Jan. 2, 2018 (HealthDay News) -- Duration of vitrectomy surgery is a significant and independent predictor of postoperative bleeding among patients with diabetic retinopathy, according to a study published online Dec. 19 in the Journal of Diabetes Investigation.

Saori Motoda, from Osaka University in Japan, and colleagues retrospectively evaluated 72 eyes of 64 patients who underwent vitrectomy for vitreous hemorrhage due to diabetic retinopathy (April 2010 and March 2014).

The researchers found that there was postoperative bleeding in 12 eyes. Duration of operation was the only significant variable associated with postoperative bleeding within 12 weeks of surgery. Aside from operation duration, factors significantly associated with the frequency of bleeding within one year of surgery included fasting blood glucose just before vitrectomy, no treatment with antiplatelet drugs, and treatment with antihypertensive drugs.

"These parameters should be of help in the selection of treatment and clinical care of diabetic patients after vitrectomy," the authors write.
