C_3f_8玻璃体腔注射后高眼压原因分析

The Cause of Intraocular Pressure Elevation Following C_3f_8 Intravitreal Injection.

目的探讨巩膜外加压联合玻璃体腔全氟丙烷(C3f8)注射治疗视网膜脱离后高眼压发生的原因及其处理措施。方法对52例(52眼)视网膜脱离患者,观察巩膜外加压联合玻璃体腔C3f8注射术后眼压情况,并测定手术前后房角开放距离500。结果 52眼中7眼术后发生高眼压(13.5%),高眼压眼手术后房角开放距离500明显减小,差异有统计学意义。术后4眼眼压自行恢复正常,3眼用药物控制到正常。结论 C3f8注射后高眼压发生率为13.5%,其中一部分可以直接恢复,其余的用药物均能很好控制。

Objective To investigate the incidence and causes of intraocular pressure （IOP） elevation in patients underwent sclera buckling with perfluoropropane（ C3fs ） intravitreal injection for retina detachment, and to evaluate the clinic management of eyes with high intraocular pressure. Methods Fifty - two patients （52 eyes） with retina detachment who underwent sclera buckling with C3fs intravitreal injection were observed. Intraocular pressure was checked by non touch tonometry. Angle opening distance 500（ AODs00 ） was evaluated by UBM preoperatively and postoperatively. Results Seven of 52 eyes were observed high intraocular pressure （ 13.5% ）. Among them the AOD^0o was significantly reduced after operation. Four eyes returned to normal without any treatment. Three eyes resumed normal by anti - glaucoma drugs. Conclusion The incidence of lOP elevation was 13.5%. Some of them could recover without any therapy, and others were controlled well by drugs.
