Anthony Economou Celebrates Recent Glaucoma Study

A new study shows promising results for those suffering from glaucoma. Anthony Economou, a glaucoma specialist, is excited about the news the study brings.

A new study brings good news for glaucoma patients. Continuous intraocular pressure measurement with a contact lens senor was deemed safe and tolerable with repeated use. Though mild adverse effects were common, researchers still believe the study is a positive for those who suffer from the disease. Anthony Economou celebrates the recent developments.

The trial consisted of 40 patients who wore the sensor for 24 hours a day on two separate occasions. During this trial, all but two people experienced some type of negative effect, explained Robert Weinreb of the University of California, San Diego. However, only seven of these 149 total events were rated as severe, which was similar to the number of adverse events seen with regular contact lenses.

The researchers then explained that the device also successfully delivered the full 24-hour pressure recordings in both sessions for 36 out of 40 people. They went on to say, “The availability of 24-hour intraocular pressure monitoring holds the promise to improve glaucoma care.”

Anthony Economou is a glaucoma expert who frequently treats the disease, and this study leaves him feeling hopeful. He says, “Intraocular pressure that is done in an office setting does not give us the full picture of IOP control for the patient during the day, week, month, etc. I am very hopeful in a medical device that would be able to give continuous IOP measurements throughout the day.”

Dr. Weinreb and his colleagues noted that getting a full 24-hour pressure curve is costly because it requires a study conducted in a sleep laboratory. Even then, the study may not have total accuracy because patients need to get woken up during the middle of the night so measurements may get taken. This is why no method currently exists to measure intraocular pressure during undisturbed sleep. Undisturbed sleep is when intraocular pressure is believed to become highest in glaucoma patients.

A Swiss company developed a soft contact lens that has two gauges that detect changes in corneal curvature that correlate with intraocular pressure. This device sends data to a small antenna attached to the skin around the eye. This antenna then passes data on to a thin cable to a recorder worn around the waist. The product is called Triggerfish. Currently, it’s approved for use in Europe but has not yet gained approval in the United States.

Dr. Weinreb went on to say, “The current study demonstrates that the contact lens sensor is a safe and well-tolerated device for repeated use in glaucoma patients or those suspected of having the disease.”


Anthony Economou is a glaucoma specialist who currently practices at Ophthalmology Consultants of Tulsa. He also serves as an adjunct professor and ophthalmology resident trainer at Oklahoma State University College of Osteopathic Medicine. He’s a board certified ophthalmologist and a fellow of four different professional organizations. Anthony Economou specializes in refractive techniques and focuses on Laser Vision Surgery.
