The authors describe a technique for hemorrhage drainage following glaucoma surgery that uses an anterior chamber maintainer to minimize risk to the anterior lens capsule.
Two patients had suprachoroidal hemorrhages following filtration surgery. Because their eyes were phakic, an anterior chamber maintainer, as opposed to a 23-gauge butterfly needle, was used for aqueous replacement during hemorrhage drainage.
The maintainer provided a stable anterior chamber environment during both drainage procedures. No damage to anterior chamber structures occurred, and the postoperative course was unremarkable in both patients.
The use of a sharp-tipped infusion cannula may be contraindicated for the phakic patient who has a suprachoroidal hemorrhage. The anterior chamber maintainer is a useful alternative instrument in such cases.
作者描述了一种青光眼手术后出血引流技术，该技术使用前房维持器将对晶状体前囊的风险降至最低。
两名患者在滤过性手术后发生脉络膜上腔出血。由于他们的眼睛有晶状体，在出血引流期间，使用前房维持器而非23号蝶形针进行房水置换。
在两次引流过程中，维持器均提供了稳定的前房环境。前房结构未受损伤，两名患者的术后病程均无异常。
对于发生脉络膜上腔出血的有晶状体患者，可能不宜使用尖嘴灌注套管。在此类情况下，前房维持器是一种有用的替代器械。
