Nearly two-thirds of untreated Chinese NTG patients progressed. Disc hemorrhage, female gender, higher IOP, shorter axial length, and lower diastolic BP predicted progression, highlighting key risk factors for clinical management.

Normal tension glaucoma involves complex vascular dysfunction and may be part of a broader small vessel disease spectrum, suggesting that managing vascular risk factors is crucial alongside IOP.

Clear lens extraction significantly reduced angle closure and widened the anterior chamber angle in PACG patients, unlike trabeculectomy, suggesting its superior anatomical benefit for angle opening.

In PACG eyes with cataract, high preoperative IOP and more glaucoma drugs predict IOP control failure. Phacotrabeculectomy is superior to phacoemulsification alone for IOP control.

For uncontrolled chronic angle-closure glaucoma without cataract, both phacoemulsification and trabeculectomy similarly reduced IOP; however, trabeculectomy reduced medication dependence more but had significantly more complications.

Researchers developed the Pressure-Cornea-Vascular Index (PCVI) for Normal Tension Glaucoma (NTG). They found PCVI, incorporating IOP, CCT, and other risk factors, predicted disease progression, offering a potential tool for identifying high-risk NTG patients.

This study found simvastatin use was associated with reduced visual field progression in normal tension glaucoma patients, suggesting a potential protective effect warranting further investigation.

This study found phacoemulsification alone opened the drainage angle and deepened the anterior chamber more effectively than combined phaco-trabeculectomy in PACG eyes, indicating better anatomical improvement.

This study found silent cerebral infarcts are an independent risk factor for visual field progression in normal-tension glaucoma, suggesting brain health impacts glaucoma severity.

For uncontrolled angle-closure glaucoma with cataracts, combined phacotrabeculectomy lowered IOP and medication use more than phacoemulsification alone, but had more complications and optic neuropathy progression.

This study found combined phacotrabeculectomy reduced glaucoma medication use more than phacoemulsification for CACG with cataract, but with more complications. Its marginal IOP benefit needs further risk-benefit evaluation.

This study found early phacoemulsification was significantly more effective than LPI in preventing subsequent IOP rise after acute angle closure, offering a superior definitive treatment, especially with high presenting IOP.

This review highlights ALPI's superiority over medication for acute IOP control, paracentesis's effectiveness in aborting attacks, and lens extraction's promise in preventing chronic glaucoma after acute primary angle closure.

This study found microincision bimanual phacotrabeculectomy effectively lowered eye pressure in glaucoma/cataract patients with minimal complications, offering a safe combined surgical option.

This study showed pressure phosphene self-tonometry in a Posner-Schlossman patient was accurate, reliable, and reduced unscheduled clinic visits by nearly 50%, offering potential for improved home IOP monitoring.

This study found pressure phosphene tonometry provides a more accurate IOP measurement in post-LASIK patients compared to non-contact and applanation tonometry, which significantly underestimate it.

This study found the self-tonometry Pressure Phosphene Tonometer (PPT) closely matched Goldmann readings in glaucoma patients. It's accurate, reproducible, and sensitive for detecting elevated IOP, making it a promising tool for home monitoring.
