Tube shunt revision with capsule excision effectively lowers IOP and medication burden. Adding Ologen did not improve success but significantly reduced complications, especially plate erosion, improving safety.

This study found ab interno gel implants can cause late bleb infections, but prompt, standard treatment leads to good visual outcomes without device removal.

Comparing Ahmed vs. Baerveldt glaucoma implants, Baerveldt showed lower 5-year failure rates and better IOP control with fewer medications, but had a small hypotony risk not seen with Ahmed.

Mathematical modeling showed glaucoma devices bypassing the trabecular meshwork and dilating Schlemm's canal significantly increase outflow facility, with longer dilation leading to greater improvement, impacting clinical efficacy.

This study found LPI significantly increased anterior chamber volume and angle in angle-closure suspects, while pilocarpine decreased them, confirming LPI's therapeutic benefit for angle opening.

This study estimated ocular rigidity in glaucoma, OHT, and normal eyes. Glaucoma patients had the lowest rigidity, while OHT patients had the highest, suggesting a more compliant eye may increase glaucoma risk.

The AVB study found Baerveldt implants had higher 1-year success rates than Ahmed implants for refractory glaucoma, but required more interventions. This informs surgical device selection.

This study found Goldmann tonometry underestimates IOP more than dynamic contour tonometry in eyes with longer axial length and lower corneal hysteresis, impacting glaucoma monitoring.

A single FDT test for glaucoma screening in high-risk populations showed low sensitivity and specificity. This means it's a poor standalone screening tool, requiring better target population definition or enhanced strategies.

A rare case showed acute angle closure glaucoma after failed carotid-cavernous fistula angiography was successfully treated with embolization, leading to excellent visual recovery. This highlights a rare iatrogenic complication and its effective management.

This study found fewer glaucoma medications, specific drug types (PGA/beta-blockers), living alone, or being widowed correlated with better adherence, and physicians struggled to predict patient adherence.

This pilot study found Heidelberg Retina Tomograph II (HRT II) showed moderate agreement with clinical glaucoma diagnosis in high-risk individuals, suggesting its potential for screening programs.

PEGS effectively treated primary angle closure unresponsive to conventional therapy, significantly lowering IOP and medication needs. This offers a viable option for challenging cases.

This case series found SLT in heavily pigmented trabecular meshworks can cause significant IOP spikes, potentially requiring surgery. Clinicians should consider this risk in such patients.
