Chapter 12: Pupillary Block Glaucomas

Yuma Masaki, Jujo Tatsuya, Sato Keiji et al.

This study found longer iris length is a significant risk factor for reverse pupillary block after intraocular lens fixation surgery, aiding surgical planning and patient counseling.

Sng Jie James, Park Ki Ho, Kim Young Kook et al.

AS-OCT revealed persistent structural differences in primary angle closure disease eyes even after LPI, suggesting its utility for assessing risk and severity post-treatment.

Tan Siyi, Li Dongjun, Liu Dianfeng et al.

AS-OCT showed Berger's space is more visible in acute angle closure and younger eyes, indicating its potential role in understanding PACD mechanisms and risk factors.

Wang Jin, Hu Keyu, Liu Zijian et al.

This study found lens-related angle-closure glaucoma patients had higher 5-year reoperation rates after Phaco-GSL than primary angle-closure, emphasizing tailored management for these high-risk individuals.

Namba Michie, Xu Benjamin Y

AS-OCT with AI objectively diagnoses and risk-stratifies angle closure more accurately than traditional methods, improving personalized care and predicting treatment outcomes for glaucoma patients.

Wang Xinyu, Wang Yunxiao, Xue Shasha et al.

LPI shifts the lens posteriorly and improves its stability in PACD, especially in PACG, which may impact IOL power calculations.

Servillo Andrea, Tun Tin A, Yoo Chungkwon et al.

This study found laser iridotomy sustained angle widening in two-thirds of patients. Persistent angle closure, seen in 33%, was predicted by a thicker iris and younger age, guiding personalized treatment.

Lin Jingjing, Mao Jianbo, He Meihui et al.

AS-OCTA-guided LPI for angle-closure suspects significantly reduced bleeding and inflammation compared to slit lamp guidance, improving safety and clinical outcomes by selecting less vascularized iris sites.

Zheng Xuanli, Zhao Fengping, Chen Huan et al.

This rabbit study shows ciliary block-induced trans-lens pressure difference drives anterior chamber shallowing, angle closure, and high IOP, providing a valuable model to understand human angle-closure glaucoma.

Nudleman Sebastian, Feiner Ella R, Affeldt Stella et al.

A 25-gauge needle effectively reopens closed iridotomies in aphakic, silicone oil-filled eyes, immediately lowering pressure and offering a simple, office-based solution for pupillary block.

Lang Tracy Z, Xu Benjamin Y, Li Zhiwei et al.

This study found acute angle closure after dilation is extremely rare (0.002%) in a large teleretinal screening program, supporting dilation's safety and questioning its contraindication in this setting.

Hsia Yun, Chang Fang-Ying, Su Chien-Chia et al.

Gong Di, Liu Yong, Dang Kuanrong et al.

This study developed machine learning models to predict postoperative hyperopic shift in PACG patients after cataract surgery, finding SVM and LR models can help guide individualized surgical decisions.

Koçer Ali Mert

This study found LPI characteristics (size, distance from pupil) influence anterior segment changes. A smaller LPI relative to pupil size or LPI placed too peripherally may reduce treatment efficacy, guiding optimal LPI placement.

Wang Jin, Wang Yue, Zhang Ye et al.

This study found non-pupillary block PACD mechanisms lead to more postoperative PAS after surgery, highlighting the need for detailed preoperative assessment to optimize long-term outcomes.

Issa Sara, Ginés-Gallego Cristina, Griffin Ben et al.

This study found adding iStent to cataract surgery for PACG modestly reduces glaucoma medications but offers similar IOP control to cataract surgery alone, with some safety considerations.

Gupta Shikha, Yadav Suresh Kumar, Panigrahi Arnav et al.

This study found that shorter anterior chamber depth and thicker lenses are key biometric risk factors for early-onset angle closure glaucoma, aiding early detection and stratification.

Chan Poemen P, Zhang Xiulan, Aung Tin et al.

Experts established consensus on acute angle closure attack (APACA) management, recommending iridoplasty, paracentesis, pupilloplasty for rapid IOP reduction, and earlier phacoemulsification to prevent vision loss.

Hong Kendra L, Xu Benjamin Y, Wang Wei et al.

Short-term changes in lens vault and angle width predict long-term angle closure progression in PACS eyes, enhancing risk assessment beyond baseline biometrics for earlier intervention.
