脉络膜暴发性出血是所有切开眼球的手术特别是白内障摘出时最危险的并发症。由于切开前房时眼压突然下降,硬化的脉络膜血管破裂,造成脉络膜上腔出血。作者在3年9个月中的3518例白内障摘出手术中有6例发生脉络膜大出血(0.17％)。这6例均属70岁以上的老人,其中5例有高血压,4例有青光眼。术前用压迫法降眼压(加压60mmHg 15分钟)。眼压下降到4mmHg的只有2例,有2例加压后眼压仍高达20与21mmHg。6例脉络膜大出血有5例导致失明(眼球内容剜出1例、眼球摘除2例、眼 Chorioreactive hemorrhage is the most dangerous complication of any ocular open surgery, especially cataract extraction. Due to a sudden drop in intraocular pressure when the anterior chamber incision, sclerosis of the choroidal blood vessels rupture, resulting in choroidal hemorrhage. The authors reported choroidal hemorrhage (0.17%) in 6 of 3518 cataract extraction procedures in 3 years and 9 months. All 6 cases were elderly over 70 years old, of whom 5 had hypertension and 4 had glaucoma. Preoperative oppression IOP (pressure 60mmHg 15 minutes). Intraocular pressure dropped to 4mmHg in only 2 cases, 2 cases of intraocular pressure after compression is still as high as 20 and 21mmHg. Five of the six cases of choroidal hemorrhage resulted in blindness (1 in the eyeball, 2 in the enucleation,
