Ambulatory monitoring of intraocular pressure (IOP) will present some challenges, but with it, a wealth of information that should lead to increased understanding of glaucoma and better patient care.
“Some ophthalmologists may be concerned about the number of patient phone calls home IOP monitoring could generate and wonder how they will analyze and interpret all of the data points that are produced,” said L. Jay Katz, MD. “We all know how critical IOP measurement is in managing glaucoma, and it is difficult to argue against the many positive aspects of getting more IOP information.”
Dr. Katz outlined the benefits of home IOP monitoring at the Glaucoma Symposium during the 2017 Glaucoma 360 meeting. He is director, Glaucoma Service, Wills Eye Hospital, and professor of ophthalmology, Thomas Jefferson University, both in Philadelphia.
Dr. Katz said that home IOP monitoring will give insight as to the patient’s true peak IOP and pattern of diurnal fluctuation. The data collected will allow determination of IOP parameters that predict glaucoma progression. In addition, this technology could conserve limited healthcare resources and allow for cost-effective delivery of care.
“Data from home IOP monitoring will minimize the need for office visits that are scheduled solely for IOP measurement and enable more timely adjustment of medication,” Dr. Katz explained, adding that he is already modifying management through telephone-only interactions for patients based on home measurements.
Information from 24-hour IOP monitoring also will enable the identification of patients who are non-adherent with medical therapy. At the same time, it might promote better adherence by making patients partners in their own care, he added.
“Don’t underestimate the value of having patients participate in monitoring their IOP,” said Dr. Katz. “Many of my patients want to check their IOP at home, and in a study evaluating an instrument for home tonometry, patients felt less anxiety about their glaucoma and enjoyed being involved in the process.”
