This paper standardized MIGS clinical endpoints and defined Minimal Clinically Important Differences (MCID) for success, improving study comparison and ensuring patient-meaningful outcomes in glaucoma care.

While 10-2 VF testing isn't routinely needed for early glaucoma, it can provide valuable information for patients with central 24-2 defects or macular OCT thinning, better correlating with structural changes.

This review found aqueous shunts effectively lower IOP in adult open-angle glaucoma, especially non-valved devices. They are superior to trabeculectomy in previously operated eyes, but less successful as primary surgery.

Richter Grace M, Takusagawa Hana L, Sit Arthur J, Rosdahl Jullia A, Chopra Vikas, Ou Yvonne et al.

Combining trabecular MIGS with cataract surgery offers a small additional IOP reduction (1.6-2.3 mmHg) over cataract surgery alone for hypertensive OAG, with no clear benefit of one procedure over another.

SLT is an effective, long-term treatment for open-angle glaucoma, comparable to ALT, and can be used as primary therapy, medication replacement, or adjunct.

Corneal hysteresis is lower in glaucoma patients and linked to increased progression risk, complementing current assessments for disease risk, even in normal-tension or controlled IOP cases.

Ophthalmic endoscopy effectively visualized diverse causes of atypical uveitis-glaucoma-hyphema syndrome, including haptic issues and vascular lesions, enabling precise surgical management for these complex cases.

This study found the ISNT rule, useful for nerve fiber layer thickness, does not reliably apply to radial peripapillary capillary vessel density in healthy eyes, impacting glaucoma assessment.

This study found Microperimeter-3 and HFA retinal sensitivities are similar and highly correlated in low-tension glaucoma, suggesting microperimetry could enhance glaucoma monitoring with its advanced features.

Law Simon K, Salazar Diana, Yu Fei, Giaconi JoAnn A, Chen Angela, Chopra Vikas et al.

Combined CyPass micro-stent and cataract surgery reduced glaucoma medications and IOP, showing 28-42% success at one year, offering a potential option for medication burden reduction.

Trabectome AIT effectively lowered IOP in uveitic glaucoma patients, offering a safe option to reduce pressure and medication, with high 12-month success, avoiding more invasive surgeries.

OCT-A revealed low tension glaucoma reduces choriocapillaris perfusion density and vessel length density in superficial macular and optic nerve areas, suggesting vascular compromise contributes to the disease.

OCTA revealed reduced retinal vascular density in preperimetric and early glaucoma, suggesting vascular changes precede advanced damage and could aid early diagnosis.

A venting stitch for valveless glaucoma shunts was studied, finding it safely and effectively controls early post-operative IOP, reducing hypotony risk and medication needs.

Implanting a second glaucoma drainage device effectively lowered IOP below 21 mmHg for up to three years, often requiring continued medication. This offers a viable option for refractory glaucoma management.

This study found glaucoma patients have significantly lower lamina cribrosa intensity than glaucoma suspects, suggesting this measurement could be a novel glaucoma indicator.

Murakami Yohko, Akil Handan, Chahal Jasdeep, Dustin Laurie, Tan James, Chopra Vikas et al.

This study found endoscopic cyclophotocoagulation (ECP) and a second glaucoma drainage device (GDD-2) are similarly effective for refractory glaucoma after a failed tube shunt, offering comparable IOP control and medication reduction.

Zhang Xinbo, Dastiridou Anna, Francis Brian A, Tan Ou, Varma Rohit, Greenfield David S et al.

This study found that baseline focal GCC and NFL loss on FDOCT are the strongest predictors of visual field progression in glaucoma, helping identify patients at higher risk.

OCT disc variables were studied for glaucoma diagnosis. Adjusting for disc size/axial length did not improve accuracy; however, rim area and vertical CDR showed high diagnostic value.

Trabectome surgery showed similar positive outcomes for both pigmentary and primary open-angle glaucoma patients, indicating its effectiveness across these glaucoma types.

Lens extraction and endoscopic cycloplasty for severe plateau iris syndrome significantly opened the angle and shrunk ciliary processes, reversing the anatomical cause of angle closure.

ECP-plus effectively lowered IOP and medication burden in refractory glaucoma patients, offering a viable treatment option with acceptable complication rates for difficult cases.
