One hundred eyes undergoing intracapsular cataract extraction and 100 undergoing extracapsular extraction were examined prospectively within one week postoperatively and again at 6-10 weeks postoperatively. Indirect ophthalmoscopy showed vitreous haemorrhage in 36% of the intracapsular group and 13% of the extracapsular group. Vitreous haemorrhage was significantly related to the occurrence of operative hyphaema (p less than 0.01) but not to iridectomy (p greater than 0.05). In the intracapsular group the use of chymotrypsin significantly reduced the incidence of vitreous haemorrhage (p less than 0.01). Three different types of vitreous haemorrhage were identified--streaks, diffuse haze, and beads in the vitreous base. Wound haemorrhage and operative hyphaema account for most cases, but it is suggested that zonular traction may be responsible for the bead haemorrhages and also for the retinal haemorrhages reported by other authors. Although no difference in visual result or incidence of cystoid macular oedema was observed in this study, a relationship to the vitreoretinal pathology of aphakia is suggested.
对100例行囊内白内障摘除术的眼睛和100例行囊外摘除术的眼睛在术后1周内进行前瞻性检查，并在术后6 - 10周再次检查。间接检眼镜检查显示，囊内组有36%出现玻璃体出血，囊外组有13%出现玻璃体出血。玻璃体出血与手术性前房积血的发生显著相关（p小于0.01），但与虹膜切除术无关（p大于0.05）。在囊内组中，使用胰凝乳蛋白酶显著降低了玻璃体出血的发生率（p小于0.01）。确定了三种不同类型的玻璃体出血——条纹状、弥漫性混浊和玻璃体基底部的珠状出血。伤口出血和手术性前房积血占大多数病例，但有人认为，悬韧带牵引可能是珠状出血以及其他作者报道的视网膜出血的原因。尽管在本研究中未观察到视力结果或黄斑囊样水肿发生率的差异，但提示与无晶状体眼的玻璃体视网膜病理有关。
