Abstract：
BACKGROUND: We present two cases of vitreous hemorrhage after micropulse cyclophotocoagulation one of which had concurrent hyphema. To the best of our knowledge, these are the first cases of vitreous hemorrhage due to micropulse CPC in the United States.
METHODS: The first case is an 82-year-old woman with bilateral severe primary open angle glaucoma. BCVA in the right eye was 20/25, and 10-2 Humphrey visual field showed severe peripheral defects. The patient underwent MPCPC of the right eye and at one week, a settled 2 mm hyphema and vitreous hemorrhage confirmed by B-scan were noted. At three months, the patient had a BCVA of 20/80 with an IOP of 12 and retina consultation deferred a PPV. The second case is of a patient with bilateral moderate stage POAG who underwent MPCPC in both eyes. His original VA was 20/200 bilaterally. At 2 weeks, RE VA was count fingers at one foot and LE was 20/150-1. At two months, a RE B scan revealed dense vitreous opacities. Retina consultation revealed vitreous hemorrhage but a PPV was deferred.
CONCLUSIONS: Clinicians should be aware of the risks of bleeding and the potential need for additional surgical interventions after MPCPC.

摘要：
背景：我们介绍了2例微脉冲睫状体光凝后玻璃体出血的病例，其中1例并发前房积血。据我们所知,这是美国首例由微脉冲CPC引起的玻璃体出血.
方法：第一个病例是一名82岁女性，患有双侧严重的原发性开角型青光眼。右眼BCVA为20/25，10-2Humphrey视野显示严重的周围缺损。患者接受了右眼的MPCPC，一周后，观察到经B超证实的2毫米前房积血和玻璃体出血.三个月后,患者的BCVA为20/80,IOP为12,视网膜会诊推迟了PPV.第二例是双侧中度POAG患者，双眼均接受了MPCPC。他最初的VA是双边20/200。两周后，REVA在一英尺处计数手指，LE为20/150-1。两个月后,REB扫描显示玻璃体混浊。视网膜会诊显示玻璃体出血，但PPV被推迟。
结论：临床医生应该意识到MPCPC后出血的风险和可能需要额外的手术干预。
