低剂量睫状体光凝术治疗急性闭角型青光眼持续高眼压状态的安全性分析OACSTPCD

Objective To analyze the safety of low-dose transscleral diode laser cyclophotocoagulation(TDCP)for the treatment of acute primary angle-closure glaucoma(APACG)under persistent high intraocular pressure(IOP).Methods A retrospective case series study.73 APACG with cataract patients(73 eyes)under persistent high IOP from January 2020 to February 2023 were retrospectively analyzed.The experimental group(35 eyes)was treated with low-dose TDCP followed by phacoemulsification combined with goniosynechialysis(2.49±0.26 w intervals).The control group(38 eyes)was treated with phacoemulsification combined with goniosynechialysis alone.IOP was compared between the two groups after nonoperative treatment,before phacoemulsification and 1day,1week,1month,3months after phacoemulsifica-tion.The incidence of intraoperative and postoperative complications was also compared between the two groups.Results There were no statistical differences in IOP between the two groups after nonoperative treatment and 1 week,1 month,3 months after phacoemulsification(all P>0.05).However,the IOP of the experimental group was lower than that of the control group before phacoemulsification and 1 day after phacoemulsification,there was a significant difference between the two groups(all P<0.05).The incidence of iris prolapse and transient high IOP,exudation in the pupil area,corneal edema after phacoemulsification in the experimental group was significantly lower than that in the control group(all P<0.05).But there was no statistical difference in the incidence of posterior capsular rupture between the two groups.Conclu-sions APACG under persistent high IOP can be treated with low-dose TDCP followed by phacoemulsification combined with goniosynechialysis after IOP reduction and intraocular inflammation was controlled.It can effectively control IOP and significantly reduce the incidence of intraoperative and postoperative complications.
