Abstract：
UNASSIGNED: To describe the clinical presentation and treatment outcomes of pupillary block glaucoma (PBG) following vitreoretinal surgery (VR surgery).
UNASSIGNED: Retrospective observational study of 6941 patients, who underwent VR surgery at a tertiary eye care centre in South India between January 2015 and December 2019. Amongst them, clinical data of 61 patients who developed PBG were taken for statistical analysis.
UNASSIGNED: Mean (SD) age was 53.90 (13.4) years and the incidence of PBG was .87%. Median (IQR) time of onset of PBG following VR surgery was 3.33 (1.1-6.6) months and majority were pseudophakic (75%). PBG resolved with Nd:YAG laser peripheral iridotomy (LPI) alone in 50 (82%) patients, whereas 11(18%) patients required additional interventions like surgical iridectomy, trabeculectomy or diode laser cyclophotocoagulation (CPC) either as a stand-alone procedure or in combination with silicone oil removal (SOR). Mean (SD) intraocular pressure at the onset of PBG was 41.61 (14.5) mmHg, which reduced drastically following LPI to 24.28 (14.9) mmHg which further dropped significantly at 6 months follow up to 20.34 (13.9) mmHg.
UNASSIGNED: Incidence of secondary PBG after VR surgery was .87%, and we observed diabetes mellitus, combined cataract and VR surgery, use of 1000cs SO endotamponade, intraoperative endolaser and multiple VR surgical interventions as common associations. Majority of the patients with PBG after VR procedures resolved with LPI and medical management. Few individuals (18%) required additional laser or surgical intervention for IOP control.

摘要：
■描述玻璃体视网膜手术（VR手术）后瞳孔阻滞型青光眼（PBG）的临床表现和治疗结果。
■6941例患者的回顾性观察研究，2015年1月至2019年12月在印度南部的三级眼科护理中心接受了VR手术。在他们当中,对61例发生PBG的患者的临床资料进行统计分析.
■平均（SD）年龄为53.90（13.4）岁，PBG的发生率为0.87%。VR手术后PBG发作的中位时间（IQR）为3.33（1.1-6.6）个月，大多数为假晶状体（75％）。50例（82%）患者单独使用Nd:YAG激光周边虹膜切开术（LPI）解决PBG，而11名（18%）患者需要额外的干预措施，如手术虹膜切除术，小梁切除术或二极管激光睫状体光凝术（CPC）作为独立程序或与硅油去除（SOR）结合使用。PBG发作时的平均（SD）眼压为41.61（14.5）mmHg，LPI后急剧下降至24.28（14.9）mmHg，在6个月后进一步显着下降至20.34（13.9）mmHg。
■VR手术后继发性PBG的发生率为0.87%，我们观察到糖尿病，白内障联合VR手术，使用1000csSO内填充剂，术中激光和多次VR手术干预是常见的关联。VR程序后，大多数PBG患者通过LPI和医疗管理解决。少数人（18％）需要额外的激光或手术干预来控制IOP。
