Patients and Methods
From September 2004 to April 2005, consecutive patients undergoing primary pars plana vitrectomy for complications of proliferative diabetic retinopathy were recruited for the prospective study. Exclusion criteria were as follows: preoperative or postoperative anticoagulant therapy, blood diseases associated with abnormal coagulation, and silicone oil infusion or 15% C3F8 tamponade as a mandatory intraoperative procedure during retina reattachment. Informed consent was obtained from each
Results
In our study, group 1 consisted of 31 cases (30 patients) and group 2 of 30 cases (29 patients). After pars plana vitrectomy with or without gas infusion, all study patients had attached retina at the end of a minimum of a 6-month follow-up. Demographic data are summarized in Table 1. Surgical findings and additional surgical procedures are shown in Table 2. Patients’ characteristics were similar between groups 1 and 2; no statistically significant differences were noted between the groups. All
Discussion
Early recurrent vitreous hemorrhage after successful operation for diabetic retinopathy can occur in as high as 63% of cases.3 To prevent recurrent vitreous hemorrhage, ε-aminocaproic acid and tranexamic acid have been used systemically9; thrombin,15, 16 sodium hyaluronate,17, 18 and silicone oil19, 20 have been used intravitreally. Mechanical tamponade of the bleeding sites by air or nonexpansile SF6–air mixture also have been tried for hemorrhage prevention.11, 12 In the present study, 10% C3F
