空泡或空泡样改变是囊膜下白内障的典型表现,偶可见于正常晶体皮质。本文作者注意到,在高压氧诱发的核性白内障和老年性灰白色核性白内障中也可见到空泡样改变,并用裂隙灯光学照像技术和显微放射照像技术(MRG,Microradiography)对这些空泡进行了定量研究。研究包括三组:一是老年性白内障组,从白内障患者的术前裂隙灯检查中,连续选出100例核性白内障以研究其核的颜色,混浊程度及是否存在空泡等。二是高压氧治疗组,25人,在12个 Cavity or vacuole-like changes are typical of subcapsular cataracts, even seen in normal crystalline cortex. The authors noted that vacuolar changes were also seen in hyperbaric oxygen-induced nuclear cataracts and senile off-white nuclear cataracts, and were assessed using slit lamp photomicrography and microradiography (MRG) Cavitation was studied quantitatively. The study included three groups: one was senile cataract group. From the preoperative slit lamp examination of cataract patients, 100 consecutive nuclear cataracts were selected to study the color of the nucleus, the degree of opacity and the presence of vacuoles. The second is hyperbaric oxygen treatment group, 25 people, in 12
