Retinal venous pulsation: Expanding our understanding and use of this enigmatic phenomenon.

We demonstrate the potential use of modified photo-plethysmographic images in assessing these various disorders.

Improving Spatial Resolution and Test Times of Visual Field Testing Using ARREST.

Spending time trying to accurately measure visual field locations that have high variability is not productive.

Inter-Relationship of Arterial Supply to Human Retina, Choroid, and Optic Nerve Head Using Micro Perfusion and Labeling.

The results indicate an inter-relationship of arterial supply to the retina, choroid, and ONH in the human eye.

Use of trypan blue to assess lymphatic function following trabeculectomy.

Eyes with lymphatic connections to drainage blebs had lower IOP and reduced requirement for topical medications. The extent of lymphatic connection to drainage blebs is related to lower IOP.

XEN Gel Stent to Treat ICE Syndrome: 4 Cases.

XEN is a safe and effective option for surgical management of ICE syndrome-related glaucoma. Further follow-up surveillance is necessary.

The Inflammatory and Foreign Body Reaction of Polymethyl Methacrylate Glaucoma Drainage Device in the Rabbit Eye.

Histopathologically, the inflammatory response toward this PMMA glaucoma drainage device was comparable to other reported GDDs. No accentuated response or adverse event was seen suggesting that PMMA may be useful as a GDD material.

Recurrent Optic Disc Hemorrhage and Its Association with Visual Field Deterioration in Glaucoma.

High-frequency ODH within optic disc sectors, equivalent to detecting ODH in 45% of 3 monthly eye examination visits, was associated with significantly worse VF progression than sectors with moderate or only 1 observed ODH.

Outcomes of 45 μm gelatin stent surgery over 24-month follow-up.

Prior cataract or trabeculectomy surgery does not appear to adversely affect gelatin stent outcomes over 2 years follow up. Gelatin stent surgery appears to have less IOP reduction effect compared to trabeculectomy at 2 years.

Long-Term Results Using Gelatin Microfistulae Implantation without Antimetabolite.

Long-Term Morphological Changes of Crosslinked Gelatin Stent.

In cases where imaging provided clear visibility, the stents exhibited signs of morphometric changes after 11 years. This degradation process seems to initiate externally, leading to luminal obstruction and eventual stent failure.

Low-Cost New Glaucoma Drainage Device in Indonesia: One Year Follow-Up of 252 Subjects.

This new GDD has comparable IOP lowering outcomes compared with other non-valved glaucoma drainage devices during 1 year follow up with similar complication rates.

XEN-45 gelatin microfistula for uveitic glaucoma.

Intermediate-term and long-term outcome of piggyback drainage: connecting glaucoma drainage device to a device in-situ for improved intraocular pressure control.

Piggyback drainage represents a viable surgical alternative for the treatment of patients with severe glaucoma with failing primary glaucoma drainage device, particularly in those at high risk of corneal decompensation.

Association between Vision-Related Difficulties in Low Light Levels and Visual Fields in Glaucoma.

Self-reported difficulties at low light levels were partially explained by binocularly IVF status in people with glaucoma.

Personalizing the Transition From 24-2 to 10-2 Visual Field Testing Using ARREST - A Simulation Study.

The A10 approach allows automated incorporation of 10-2 locations into the 24-2 pattern that are customized to individuals without increasing test times.

Surgical Techniques for the Virna Glaucoma Implant: A Low-Cost New Glaucoma Drainage Device-Response.

Inter-device comparison of retinal sensitivity measurements: the CenterVue MAIA and the Nidek MP-1.

The large LoA and variation in scotoma mapping concordance suggest that the same microperimeter should be used for follow-up examination. We recommend caution in comparing results derived from different types of microperimeters.

Cerebrospinal fluid pressure and the eye.

Additionally, a high proportion of astronauts develop features similar to idiopathic intracranial hypertension that persist for years after returning to Earth.

Occurrence of CYP1B1 Mutations in Juvenile Open-Angle Glaucoma With Advanced Visual Field Loss.

Patients with advanced JOAG based on visual field loss had enrichment of CYP1B1 pathogenic variants and a more severe phenotype compared with unaffected controls and patients with nonadvanced JOAG.
