Abstract
PURPOSE This study describes a novel surgical technique of fibrin glue-assisted retinopexy for rhegmatogenous retinal detachment (GuARD) without oil or gas tamponade after pars plana vitrectomy (PPV). METHODS This pilot clinical trial included five eyes of five patients with rhegmatogenous retinal detachments (RD). A complete PPV was done in all cases followed by fluid-air exchange, laser photocoagulation around the break/s, and application of 0.1-0.2 mL of fibrin glue. No air, long-acting gas or silicone oil was used subsequently. No specific postoperative positioning was prescribed. The primary outcome measure was efficacy of the procedure defined as successful anatomical retinal reattachment. Secondary outcome measures were postoperative improvement in best corrected visual acuity (BCVA) and complications. RESULTS The median age of patients was 55 (range: 36-61 years) years and median duration of symptoms was 15 (range: 7-60) days. All eyes were pseudophakic, four eyes had inferior and one eye had total RD. Successful retinal reattachment was achieved in all (100%) cases and was maintained at the end of 3-8 months of follow-up. The median BCVA improved from 20/100 preoperatively to 20/80 at 1-week and 20/50 at 1-month postoperatively. None of the eyes had any postoperative complications such as elevated intraocular pressures or unexpected inflammation. CONCLUSION The findings of this study suggest that GuARD is a promising technique for treatment of rhegmatogenous RD that may allow early visual recovery while avoiding the problems of gas or oil tamponade and obviating the need of postoperative positioning.

Abstract
AIMS: To evaluate the effect of tranexamic acid on early postvitrectomy haemorrhage in diabetic patients. METHODS In a clinical trial, 62 diabetic patients scheduled for vitrectomy were randomly assigned to two groups. The treatment group (32 eyes) received two doses of tranexamic acid (10 mg/kg) shortly before and after the operation intravenously, continued orally for 4 days (20 mg/kg/8 hours). The control group (30 eyes) received no medication. Both media clarity and visual acuity were compared during 4 weeks. RESULTS Four weeks after surgery visual acuity was low (< or =1 metre counting fingers) in 21.4%, moderate (>1 metre counting fingers but<20/200) in 14.3%, and good (> or =20/200) in 64.3% of the treated group. Corresponding figures in the control group were 26.1%, 26.1%, and 47.8%, respectively. These differences were of no statistical significance. The ratio of mild to severe vitreous haemorrhage during the first 4 days and after 4 weeks was 79% to 21% and 82% to 18% in the treatment group and 76.7% to 23.3% and 78.3% to 21.7% in the control group respectively, which showed no statistically significant difference. CONCLUSION Tranexamic acid, with the method of administration in this study, had no effect on reducing early postvitrectomy haemorrhage in diabetic patients.
