Adherence to World Glaucoma Association Guidelines for Surgical Trials in the Era of Microinvasive Glaucoma Surgeries.

Published comparative MIGS trials show low adherence (45.6%) to the WGA guidelines.

Effect of Head Position and Weight Loss on Intraocular Pressure in Obese Subjects.

Obesity is associated with increased IOP compared with normal weight controls, but not with the magnitude of postural IOP change across different seated and supine positions.

Twenty-four hour intraocular pressure monitoring with the SENSIMED Triggerfish contact lens: effect of body posture during sleep.

Sleep position affects IOP as measured by TF in some patients with progressive glaucoma.

A Randomized Controlled Trial to Determine the Effect of Inhaled Corticosteroid on Intraocular Pressure in Open-Angle Glaucoma and Ocular Hypertension: The ICOUGH Study.

We found no clinically significant increase in mean IOP in patients with well-controlled open-angle glaucoma and ocular hypertension after 6 weeks of twice-daily inhaled fluticasone propionate compared with inhaled placebo.

Repair of Exposed Ahmed Glaucoma Valve Tubes: Long-term Outcomes.

Buccal mucous membrane grafts in combination with a lamellar corneal patch graft is a viable surgical strategy for eroded GDDs, providing good long-term outcomes; however, later interventions may be needed.

Self-perceived Impact of Glaucomatous Visual Field Loss and Visual Disabilities on Driving Difficulty and Cessation.

Patients with moderate/severe glaucomatous visual field loss reported significantly higher percentage of driving cessation, presence of glare and difficulty with dark adaptation.

Long-term Follow-up of Ahmed Glaucoma Valve Tube Position Changes.

In total, 11 eyes of 9 patients were included in the analysis.

Vection Responses in Patients With Early Glaucoma.

Two experiments have replicated the finding that vection responses are longer in patients with glaucoma than in controls; however, the CSFI is not related to vection responses.

A Data-Driven Model for Simulating Longitudinal Visual Field Tests in Glaucoma.

A novel simulation model generates glaucomatous VF sequences that are practically equivalent to longitudinal VFs from patients with glaucoma.

Binocular Summation of Visual Acuity at High and Low Contrast in Early Glaucoma.

For patients with early glaucoma, binocular summation function for visual acuity was preserved at both contrast levels.

Argon Laser Iridoplasty for Plateau Iris Syndrome: Long-Term Outcomes of 48 Eyes.

Postural Changes and the Trans-Lamina Cribrosa Pressure Difference: A Pilot Study in Neurosurgical Patients without Glaucoma.

In this pilot study of 20 neurosurgical patients without glaucoma, posture-induced TLCPD changes were variable.

Plateau Iris: The Terminology and Clinical Relevance.

Response: Long-term Follow-up of Ahmed Glaucoma Valve Tube Position Changes.

Comparison of trabeculectomy versus Ex-PRESS: 3-year follow-up.

We found no difference in success rates, mean IOP or other secondary outcomes between Ex-PRESS and trabeculectomy after 3 years of follow-up.

Glaucoma Severity and Participation in Diverse Social Roles: Does Visual Field Loss Matter?

Participation in diverse social roles is valued by individuals with glaucoma.

Flow Test to Predict Early Hypotony and Hypertensive Phase After Ahmed Glaucoma Valve (AGV) Surgical Implantation.

Preoperative OP and CP may predict early hypotony or HP and may be used as a guide as to which AGV valves to discard before implantation surgery.

Same-Day Bilateral Glaucoma Laser Treatments in Ontario: 2000 to 2013.

The increase in same-day bilateral trabeculoplasties coincided with the introduction of selective laser trabeculoplasty.

Neuroretinal Rim Area Change in Glaucoma Patients With Visual Field Progression Endpoints and Intraocular Pressure Reduction. The Canadian Glaucoma Study: 4.

Patients with a VF endpoint had a median rim area rate that was nearly 3 times worse than those without an endpoint.

Comparison of visual recovery following ex-PRESS versus trabeculectomy: results of a prospective randomized controlled trial.

Although there was no difference in mean VA between the Ex-PRESS and trabeculectomy groups at any time point, trabeculectomy eyes were more likely to lose ≥2 Snellen lines.

Priming the Ahmed Glaucoma Valve: pressure required and effect of overpriming.

This study demonstrates that the priming pressure is consistent at around 3000 mm Hg. In addition, over-priming is not likely to damage or disturb the closing pressure.

The relationship between sociodemographic factors and persistence with topical glaucoma medications.

Below average socioeconomic status may negatively impact persistence with topical glaucoma medications, potentially threatening long-term visual outcomes.

Prospective Randomized Study Comparing Ex-PRESS to Trabeculectomy: 1-Year Results.

There was no statistically significant difference between the trabeculectomy and Ex-PRESS groups regarding IOP, success rates, complications, additional interventions, and bleb morphology.
