Many Glaucoma Patients Don’t Take Medication Properly


A study that appears in the May edition of Ophthalmology, the clinical journal of the American Academy of Ophthalmology, shows that as many as 47 percent of patients receiving glaucoma therapy do not comply with their doctor’s prescribed medicine regimen. This is in startling contrast to the 90 percent of doctors who believe that their patients are following the prescribed treatment.

“Non-adherence to the glaucoma therapy is probably what causes patients to go blind,” said Alan L. Robin, M.D., author of the study and Academy member. “Cost of medications, multiple medications, confusing instructions all contribute to a patient’s non-compliance to their therapy.”

Dr. Robin refers to a 2003 Harris poll that illustrates this emerging health concern:

• One-third of patients surveyed took their medications less often than directed
• One-quarter delayed refilling prescriptions
• One-fifth failed to fill prescriptions
• One-fifth stopped taking a medication sooner than prescribed

The World Health Organization (WHO) estimates that worldwide, fifty percent of patients take medications improperly, at a global cost of more than $100 billion in resulting hospital admissions and lost productivity.

Dr. Robin’s study compares medication refill rates for two groups of glaucoma patients. The first group takes a single medication for one year without needing a second medication to control intraocular pressure. The second group takes the same single glaucoma medication for one year, but then a second glaucoma medication is added for an additional year. As soon as a second medication is added, approximately one-half of the second group delayed refilling prescriptions of the first medication by 5 days or more, and 22 percent waited an additional 15 days or more to pick up their pills.

“Non-compliance is a bigger problem then we imagined, and glaucoma therapy is only the tip of the iceberg,” added Dr. Robin. “It becomes a life-and-death situation for doctors to educate and motivate their patients on their therapy and with glaucoma; this may lead to visual disability and blindness.”

Dr. Robin’s study suggests that eye diseases including glaucoma are one of the five conditions at the bottom of the medical condition adherence list. The four other ailments include renal and pulmonary diseases, diabetes, and sleep disorders.

Dr. Robin is an associate professor at both the Johns Hopkins University Schools of Medicine and Public Health.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
