Under Pressure: Protecting Neurons From Glaucoma

Pete Williams, Ph.D., is researching how to protect the optic nerve from changes in intraocular pressure caused by glaucoma.  He’s identifying the genes that show changes in expression in the glaucoma-affected mice compared to their unaffected counterparts. Next, Dr. Williams will test which ones affect the symptoms. By disrupting those genes that are early contributors to the disease, Dr. Williams intends to prevent nerve degeneration. Read more →


Marijuana-Derived Eye Drop?!

Nemus Bioscience may soon begin clinical testing of a marijuana-derived eye drop for the treatment of glaucoma. Read more →

Stem cell secretions may protect against glaucoma

Stem cell treatment for glaucoma is both controversial and complicated. There may, however, be a simpler solution around the corner. Researchers have discovered that “exosomes” derived from stem cells protect damaged rat optic nerves. Exosomes are packages of lipids (fats), proteins, and small strands of RNA. They are produced by stem cells and may act a “messengers” between cells. In theory, exosome treatment of glaucoma would require injecting these microscopic “packages” into the eye on a regular basis. Still, that’s much simpler than working with whole cells (and potentially less controversial as well). Read more →

MicroPulse® P3 “Cyclophotocoagulation” – A Burst of Good News for those with Glaucoma

A new type of minimally invasive glaucoma surgery (MIGS) that has quietly joined the fray in the battle against glaucoma: MicroPulse® P3 “Cyclophotocoagulation”. Traditional methods of cyclophotocoagulationburn the ciliary body. MicroPulse® P3 “Cyclophotocoagulation”, however, uses a slow application of laser energy that is “chopped” into micropulses (or, bursts). Each pulse heats up, but does not burn or destroy eye tissue. In between each pulse is a pause. This pause allows the eye tissue to cool off. In this manner the eye tissue is changed rather than destroyed.Read more →


Vitamin B-3 successfully prevents glaucoma in mice

Study suggests that treatments with vitamin B-3 – also known as niacin, or nicotinamide – improves the metabolism of aging retinal ganglion cells, keeping them healthy.” Read more →

Effect of Type and Daily Dosage of Statin on Risk of Open-Angle Glaucoma

Cholesterol lowering statin drugs may protect against developing glaucoma. “As statin use is increasing, there is growing evidence that it can reduce cholesterol levels and may also be protective against development of open-angle glaucoma. This large retrospective study analyzed over 25,000 cases…” Read more →


24 Hour IOP Measurements May Be Predictive of Visual Field Worsening in Patients with Glaucoma

Dr. Gustavo De Moraes and his team of researchers presented a paper, which showed that a single 24 hour measurement with the SENSIMED Triggerfish® contact lens could predict the risk of worsening visual field loss over the next 5 yearsRead more →

Introducing Canaloplasty with the Stegmann Canal Expander®

The inventor of canaloplasty, Dr. Robert Stegmann,  invented yet another device that could  further expand the canal and make canaloplasty even more effective at lowering the IOP in patients with glaucoma. It is a tube-shaped scaffolding device, about twice the thickness of a human hair. It is placed into Schlemm’s canal after canaloplasty has been performed. Once inserted, the Stegmann Canal Expander® keeps up to half of the canal open – permanently.  Read more → 

What Does Cellophane Have to Do with Glaucoma?

Cellophane maculopathy or Epiretinal Membrane—which closely resembles SaranTM Wrap—is known to be associated with growth of a particular type of cell called glial cells. These cells respond to inflammation. Recent evidence suggests that glial cells may also be activated in those with glaucoma. In a study conducted by Dr. Luna Xu and colleagues, eyes which required surgery to treat cellophane maculopathy had evidence of worse glaucoma than the fellow eyes without the epiretinal membrane.  Read more →

Inflammation After Endoscopic Cyclophotocoagulation (ECP) Glaucoma Surgery

Endoscopic Cyclophotocoagulation (ECP) is generally thought of as a relatively low risk glaucoma treatment. One potential risk, however, is uveitis (inflammation) of the eye. This inflammation has been reported to occasionally be quite severe after ECP. Read more →

Update on the Stem Cell Treatment of Glaucoma – Encouraging the Growth of Trabecular Meshwork Cells

Dr. Markus Kuehn  and colleagues are currently working on  induced pluripotent stem cells (iPSC-TM). In mice transplanted with iPSC-TM the aqueous humor outflow facility (drainage of fluid out of the eye) improved within two months of surgery. This was associated with increased cellular density of the trabecular meshwork, IOP control, and protection of the retinal ganglion cells (usually damaged by elevated IOP). Read more →


Central Visual Field Loss Associated with More Rapid Vision Loss in Glaucoma

There is now evidence that early central loss of vision can predict how quickly your glaucoma will worsen. While it’s inconvenient to sit through two separate visual fields—for those eyes with early central vision loss, more frequent visual field testing should be performed. Ideally, both 24-2 and 10-2 fields would be repeated 2-4 times per year.—the added information will help your glaucoma surgeon best protect you from losing vision Read more →

Potential predictor of glaucoma damage identified 

Research in mice and patients suggests biomarker could predict vision loss.”A biomarker that appears linked to damage to cells in the retina of the eye has been identified by researchers. The marker may make it possible to better monitor the progression of glaucoma, as well as the effectiveness of treatment for the blinding disease.” Read more →

Glaucoma Visual Field Progression-IOP-Tonometers

For those with glaucoma, higher intraocular pressure (IOP) is associated with faster vision loss. There are now multiple different types of tonometry used to check IOP. It’s reasonable, then, to ask, “Is any one of these methods of checking IOP better at monitoring glaucoma?” Read more →
