目的观察高血压病患者白内障超声乳化术前术中的瞳孔动态变化。方法 25例(30眼)观察组与26例(30眼)相应年龄非高血压病对照组的术眼,手术前用美多丽滴眼散瞳。测定术前未散瞳的瞳孔直径(D1)、术前散瞳后最大瞳孔直径(D2)、超声乳化注吸后的瞳孔直径(D3)、散瞳开始到最大瞳孔直径所需的时间(T1)。结果两组患者D1、D2差异无统计学意义(P>0.05);两组患者D3、T1差异有统计学意义(P<0.05),观察组T1较对照组延长。结论高血压病患者白内障手术前散瞳等待时间延长,手术中较对照组病例的瞳孔明显缩小。
Objective To observe the changes of pupil before cataract phacoemulsification in hypertensive patients. Methods 25 cases (30 eyes) observation group and 26 cases (30 eyes) corresponding age non-hypertensive control group of eyes, multivision eye drops before surgery. (D1), the maximum pupil diameter (D2) after preoperative dilation, the pupil diameter after phacoemulsification (D3), the time required for mydriasis to reach the maximum pupil diameter (T1) . Results There was no significant difference in D1 and D2 between the two groups (P> 0.05). The difference between D3 and T1 in the two groups was statistically significant (P <0.05). The T1 in the observation group was longer than that in the control group. Conclusion Hypertension patients with cataract preoperative mydriasis waiting time is prolonged, the surgery compared with the control group, the pupil was significantly reduced.
