目的探讨抗青光眼术后低眼压性浅前房发生的相关因素及处理方法。方法回顾性总结我院315例行小梁切除术和39例行虹膜嵌顿术的青光眼患者术后低眼压性浅前房的发生率,并分析术前眼压,手术方式,术后结膜伤口渗漏,滤过过强及脉络膜脱离等与术后低眼压性浅前房的关系。结果发生低眼压性浅前房68眼(16.31%)。术前眼压≤21mmHg者201眼中发生低眼压性浅前房16眼(7.96%);其中小梁切除术185眼,发生低眼压性浅前房16眼(8.65%),虹膜嵌顿术16眼,无低眼压性浅前房发生。术前眼压22～30mmHg者126眼中发生低眼压性浅前房28眼(22.22%);其中小梁切除术114眼,发生低眼压性浅前房27眼(23.68%),虹膜嵌顿术12眼,发生低眼压性浅前房1眼(8.33%)。术前眼压31～40mmHg者72眼中发生低眼压性浅前房26眼(36.11%);其中小梁切除术65眼,发生低眼压性浅前房25眼(38.46%),虹膜嵌顿术7眼,发生低眼压性浅前房1眼(14.29%)。术前眼压>40mmHg者18眼中发生低眼压性浅前房8眼(44.44%);其中小梁切除术14眼,发生低眼压性浅前房7眼(50%)虹膜嵌顿术4眼,发生低眼压性浅前房1眼(25%)。术后结膜伤口渗漏11眼(16.18%),滤过过强38眼(55.88%),脉络膜脱离7眼(10.29%),另有原因不明者12眼。结论抗青光眼术后低眼压性浅前房与多种因素有关。①术前眼压越高,发生率越高;②虹膜嵌顿术较小梁切除术发生率低;③滤过过强者发生率最高。
Objective To investigate the related factors and treatment of low tension ocular shallow anterior chamber after anti-glaucoma surgery. Methods The incidence of postoperative low-tension anterior chamber in 315 cases of trabeculectomy and 39 cases of iris-incarceration in our hospital were retrospectively analyzed. The preoperative intraocular pressure, operation method, postoperative conjunctiva Wound leakage, excessive filtration and choroidal detachment and postoperative low intraocular pressure shallow anterior chamber relationship. RESULTS: 68 eyes (16.31%) had hypoocclular shallow anterior chamber. There were 16 eyes with low intraocular pressure (7.96%) in 201 eyes with preoperative intraocular pressure ≤21mmHg, 185 eyes underwent trabeculectomy, 16 eyes (8.65%) had shallow interocular pressure and shallow anterior chamber iris Twenty-six eyes, without hypotony occurred in shallow anterior chamber. There were 28 eyes (22.22%) with low intraocular pressure in 126 eyes with preoperative intraocular pressure of 22 ~ 30mmHg. Among them, 114 eyes underwent trabeculectomy, 27 eyes (23.68%) had shallow interocular pressure and shallow anterior chamber, Dayton surgery 12 eyes, low pressure ocular shallow anterior chamber occurred (8.33%). There were 26 eyes (36.11%) with low intraocular pressure in 72 eyes with preoperative intraocular pressure from 31 to 40 mmHg, 65 eyes underwent trabeculectomy, 25 eyes (38.46%) with shallow interocular pressure and shallow anterior chamber, Dayton operation was performed in 7 eyes, and in 1 case (14.29%) with low IOP in shallow anterior chamber. Preoperative intraocular pressure> 40mmHg occurred in 18 eyes of low pressure ocular shallow anterior chamber in 8 eyes (44.44%); trabeculectomy in 14 eyes, the occurrence of low pressure ocular shallow anterior chamber in 7 eyes (50%) iris incarceration 4 eyes, 1 case of hypotony shallow anterior chamber occurred (25%). Postoperative conjunctival wound leakage in 11 eyes (16.18%), hyperfiltration 38 eyes (55.88%), choroidal detachment in 7 eyes (10.29%), while the unexplained 12 eyes. Conclusion Anti-glaucoma postoperative hypotony pressure shallow anterior chamber and a variety of factors. ① preoperative intraocular pressure is higher, the higher the incidence rate; ② iris incarceration less incidence of lower incidence of resection of the beam; ③ filtration rate was the highest.
