PATIENTS AND METHODS: This retrospective r eview examined consecutive cases of ocular injury associated with intraocular fo reign bodies; 71 eyes included had a single metallic intraocular foreign body (< 5 mm) located in the vitreous cavity removed by external magnet or intraocular forceps. Variables included preoperative and postoperative visual acuity, retina l break formation, retinal detachment, presence of an afferent pupillary defect, intraocular pressure, entrance site, foreign body size, method of extraction, a nd time between occurrence and surgical extraction. RESULTS: Factors predictive of good visual outcome (visual acuity >20/200) were: shortest interval between t rauma and foreign body extraction, preoperative visual acuity of 20/200 or bette r, and absence of afferent pupillary defect. CONCLUSIONS: In this nonrandomized study, good visual results could be obtained in eyes undergoing prompt foreign b ody removal, especially those with good preoperative visual acuity and no affere nt pupillary defect.展开更多

Methods: In a clinical trial, 62 diabetic patients s cheduled for vitrectomywere randomly assigned to two groups. The treatment group (32 eyes) received two doses of tranexamic acid (10 mg/kg) shortly before and a fter the operation intravenously, continued orally for 4 days (20 mg/kg/8 hours) . The control group (30 eyes) received nomedication. Bothmedia clarity and visua l acuity were compared during 4 weeks. Results: Four weeks after surgery visual acuity was low (≤1 metre counting fingers) in 21.4%, moderate (> 1 metre count ing fingers but < 20/200) in 14.3%, and good (≥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 rat io of mild to severe vitreous haemorrhage during the first 4 days and after 4 we eks 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 s ignificant difference. Conclusion: Tranexamic acid, with the method of administr ation in this study, had no effect on reducing early postvitrectomy haemorrhage in diabetic patients.展开更多
