WASHINGTON — Take-home devices can provide IOP monitoring over longer periods of time and give doctors a better understanding of their patients’ glaucoma progression.

On Glaucoma Day at the American Society of Cataract and Refractive Surgery meeting, Barbara M. Wirostko, MD, said IOP measurements have traditionally been limited to a single time when the patient is being tested in the office.

“When we bring a patient into the office several times a year, we spend a few seconds measuring their IOP,” she said. “There are over 31 million seconds in a year. We only get a small snapshot.

Wirostko said IOP has a lot of variability and fluctuates based on many factors, including time of day, cortisol levels, and exercise.

She said the same principles used in diabetes or blood pressure monitoring can be used in glaucoma and gave some examples of monitoring systems that can be used to capture IOP levels over a longer period.

The Triggerfish (Sensimed) is a contact lens that patients wear for 24 hours, including at night, and the Eyemate (Implandata Ophthalmic Products) is an implantable sensor currently undergoing clinical studies in the United States.

The iCare tonometer has already received clearance in the United States and shares similar technology to that traditionally used in the office, Wirostko said. Patients use the device at home, and previous research has shown it can supplement tonometry in the clinic, she said.

Wirostko said home tonometry has the potential to change the way glaucoma specialists manage patients, especially in the world of telehealth.

“I’ve used it to see responses to surgery and lasers,” she said. “This will allow us to intervene earlier.”
