The management of traumatic hyphaema with raised intraocular pressure and corneal blood staining is difficult. Residual blood clots after anterior chamber washout are responsible for sustained postoperative elevation of intraocular pressure, even after trabeculectomy and clot evacuation.
Thirty-five patients with traumatic hyphaema, elevated intraocular pressure and varying degrees of corneal blood staining underwent a combined trabeculectomy with manual clot evacuation from the anterior chamber in a general hospital.
The postoperative control of intraocular pressure was found to be adequate in all patients at the end of two months. Examination of the posterior segment was made possible earlier. Although the procedure is more complex, no significant complications were encountered.
In patients presenting with traumatic hyphaema, secondary glaucoma and corneal blood staining, trabeculectomy with manual extraction of the clot through a large incision appears to be a safe and reliable procedure where medical therapy fails to control the intraocular pressure.
外伤性前房积血伴眼压升高和角膜血染的处理较为困难。即使在小梁切除术和血凝块清除术后，前房冲洗后残留的血凝块仍会导致术后眼压持续升高。
35例患有外伤性前房积血、眼压升高和不同程度角膜血染的患者在一家综合医院接受了小梁切除术联合从前房手动清除血凝块的治疗。
在两个月结束时，发现所有患者的眼压在术后均得到了充分控制。更早地对眼后段进行检查成为可能。尽管该手术更为复杂，但未出现明显并发症。
对于患有外伤性前房积血、继发性青光眼和角膜血染的患者，当药物治疗无法控制眼压时，通过大切口手动取出血凝块的小梁切除术似乎是一种安全可靠的手术方法。
