Abstract:

Objective   To assess the effect of routine surgery and  minimally invasive surgery with vitrectomy devices for severe hyphema(black ball).   Methods   28 patients who suffering from severe hyphema(black ball) from January 2010 to December 2011 were divided into two groups. The group A (15 patients,15eyes) were cured by routine surgery and the group B were cured by minimally invasive surgery with vitrectomy devices. Regression time of the corneal edema after surgery, vision, rate of rehaemorrhagia, complicated cataract and intraocular hypertension were  recorded for analysis. Results   The regression time of the corneal edema after surgery was (5.1±1.5)days in group A and (3.1±1.3)days in group B. The vision was 4.02±1.12 and 4.65±0.21 on 3 and 7days after surgery in group A, but was 4.62±1.18 and 4.91±0.17 in group B. There were 4 cases of rehaemorrhagia and 4 complicated cataract in group A but none rehaemorrhagia and 1 complicated cataract in group B, and the differences were statistical. There were no differences in rate of intraocular hypertension  between the two groups. Conclusion   Minimally invasive surgery with vitrectomy devices for severe hyphema(black ball) can made patients less impairment and obtain better vision.
