Purpose: To investigate the efficacy and safety of non-valved Aurolab aqueous drainage implant (AADI) surgery combined with phacoemulsification in eyes with refractory glaucoma and coexistent cataract.

Methods: Included patients of 18 years or older who underwent combined AADI-Phacoemulsification from June 2015 to January 2017 with at least 12 months of consecutive follow-up. The best-corrected visual acuity, intraocular pressure (IOP), and the number of IOP-lowering medications were recorded at baseline, 2 weeks, 1, 3, 6, 12, 18, and 24 months. Cumulative probability of success was defined as IOP < 18 mmHg or 30% reduction from the baseline at two consecutive postoperative visits after 3-months. Loss of light perception or reoperation for uncontrolled glaucoma or a complication was considered failure apart from IOP criteria.

Results: Seventeen eyes of 17 patients with a mean follow-up of 22.6 ± 4.0 months were included. Baseline IOP and ocular hypotensive drugs reduced significantly from 27.9 ± 7.6 mmHg to 14.0 ± 3.0 mmHg (p < 0.001) and 3.24 ± 0.7 to 1.33 ± 1.1 (p = 0.001), respectively, at 24 months. Cumulative probability of qualified success was 71.4% (95% Confidence Interval [CI] 40.6-88.2%) at 3 months and was maintained from 6 months onwards at 64.3% (95% CI 34.3-83.3%), up to 2 years. Intravitreal steroid was injected in one eye (5.9%) of chronic cystoid macular edema, and tube repositioning was done in another for focal corneal decompensation.

Conclusions: Combined AADI-Phacoemulsification surgery is a safe and effective option in providing favorable visual and IOP outcomes at an affordable cost in eyes with refractory glaucoma and coexistent cataract.

A novel pre-magnetized ZVI/PS pretreatment for improving sludge dewaterability: The role of EPS fractions.

Xiao Ling Minjie Chen Anhong Cai Honglei Sun Shanlin Xu Lei Wang Xueyan Li Jing Deng

J Environ Manage 2022 Sep 1;318:115646. Epub 2022 Jul 1.

College of Civil Engineering, Zhejiang University of Technology, Hangzhou 310023, China. Electronic address:

The dewaterability of waste-activated sludge (WAS) has been extensively examined using zero-valent iron (ZVI)-based advanced oxidation processes (AOPs). However, the high dosage and low utilization efficiencies of ZVI cast doubt on the dependability and viability of ZVI-based AOPs. In this study, we successfully demonstrated pre-magnetization as an efficient, chemical-free, and ecological method for improving the efficiency of sludge dewatering by ZVI/persulfate (PS) process, in which the reduction ratios of capillary suction time (CST) and specific resistance to filtration (SRF) increased by 8.

A Review of Corneal Biomechanics and Scleral Stiffness in Topical Prostaglandin Analog Therapy for Glaucoma.

Authors:
Steven R Shen Gloria P Fleming Shelly Gupta Jain Cynthia J Roberts

Curr Eye Res 2022 Aug 5:1-10. Epub 2022 Aug 5.

Department of Ophthalmology and Visual Sciences, The Ohio State University, Columbus, OH, USA.

Purpose: The mechanism of action underlying prostaglandin analog (PGA) therapy involves changes in the expression of different metalloproteases to increase permeability of the sclera and allow increased aqueous humor outflow through this alternative drainage pathway. This alteration of structure impacts cornea/scleral biomechanics and may introduce artifact into the measurement of intraocular pressure (IOP) in the clinical setting.

Methods: A literature search reviewing the impact of PGA therapy on corneal and scleral biomechanics was conducted including basic studies, clinical studies with treatment naïve patients, and a clinical study examining the cessation of PGA therapy. Read More

Cationic Mechanosensitive Channels Mediate Trabecular Meshwork Responses to Cyclic Mechanical Stretch.

Susu Chen Wenyan Wang Qilong Cao Shen Wu Ningli Wang Lixia Ji Wei Zhu

Front Pharmacol 2022 19;13:881286. Epub 2022 Jul 19.

School of Pharmacy, Qingdao University, Qingdao, China.

The trabecular meshwork (TM) is responsible for intraocular pressure (IOP) homeostasis in the eye. The tissue senses IOP fluctuations and dynamically adapts to the mechanical changes to either increase or decrease aqueous humor outflow. Cationic mechanosensitive channels (CMCs) have been reported to play critical roles in mediating the TM responses to mechanical forces. Read More

Introduction: XEN 45® gel stent is an ab interno aqueous humor drainage device indicated for moderate glaucoma refractory to medical management. Its efficacy has been demonstrated in primary open-angle glaucoma (POAG). However, there are few studies on secondary glaucoma, including steroid-induced glaucoma (CG), defined as optic neuropathy induced by using local or systemic corticosteroids without increased flare.
