摘要
目的观察超声乳化白内障摘出术对抗青光眼术后白内障眼眼压及滤过泡的影响。方法共收集27例33眼抗青光眼术后有功能性滤过泡眼患者,观察术前及术后各随访阶段眼压变化,并于术前及术后第18个月做滤过泡UBM检查,观察巩膜瓣下滤过通道的可见性及滤过泡内反射强度的变化。结果术后1d、1周、1个月、3个月、6个月、12个月和18个月平均眼压较术前分别升高了5.16mmHg(1kPa=7.5mmHg)、3.74mmHg、3.07mmHg、2.99mmHg、2.72mmHg、2.55mmHg和2.65mmHg,其差异均具有统计学意义(均为P=0.000)。术后18个月滤过泡内部巩膜瓣下滤过通道的可见性及滤过泡内反射强度与术前比较,差异均无统计学意义(均为P>0.05)。结论超声乳化白内障摘出术能够升高眼压,但对滤过泡UBM图像中特征性结构的影响较小。
Objective To investigate effects of phacoemulsification on intraocular pressure（IOP） and filtering blebs in eyes with cataract after anti-glaucoma surgery.Methods There were 27 cases（33 eyes） with functional filtering blebs after anti-glaucoma surgery.Changes of IOP were observed before and after operation at each following up time.Ultrasound biomicroscope images of filtering blebs were taken before operation and at the 18th month after phacoemulsification,respectively.Visibility of filtering routes under the scleral flap and reflectivity inside the blebs were observed.Results Compared with that before operation,the mean IOP increased 5.16 mmHg（1 kPa=7.5 mmHg）,3.74 mmHg,3.07 mmHg,2.99 mmHg,2.72 mmHg,2.55 mmHg and 2.65 mmHg at 1 day,1 week,1 month,3 months,6 months,12 months and 18 months after phacoemulsification,respectively.There was significant difference（all P=0.000）.There was no statistically significant difference in visibility of filtering routes under the scleral flap and reflectivity inside the blebs between before and after phacoemulsification（P=0.076,P=0.061）.Conclusion Phacoemulsification significantly increases IOP,but has little effects on features of filtering blebs in ultrasound biomicroscope images.
