Intraocular pressure (IOP) stands as the only modifiable risk factor in glaucoma

Glaucoma is a chronic, progressive eye disease that can lead to irreversible vision loss without timely intervention. Intraocular pressure (IOP) stands as the only modifiable risk factor in glaucoma.

Regular IOP monitoring is a crucial part of glaucoma care. However, sporadic clinic IOP measurements do not reflect real-world values or fluctuations that occur throughout the day and night. Knowing a patient’s true maximum IOP is key to better understanding the condition and creating personalized glaucoma treatment plans.

Data beyond a single measurement: Studies show IOP peaks occur outside of clinical hours

Traditional clinic measurements only offer a snapshot of a patient's IOP, often missing the true peaks and variations that occur outside office hours. Studies have revealed that wide fluctuations of IOP, and elevated IOP, contribute to glaucoma progression. This insight underscores the need for continuous monitoring and understanding of IOP variability to optimize glaucoma care.

The range of IOP variations in glaucoma patients can be three times higher than in normal subjects1. IOP variation in normal eyes is generally between 2-6 mmHg whereas in glaucoma patients, it can reach 10 mmHg or more2. Studies have reported IOP peaks outside of office hours in 62%, 66%, and 52% of glaucoma patients2,4,5

Revolutionizing glaucoma care with iCare HOME2 — a modern approach to 24-Hour IOP monitoring

The iCare HOME2 tonometer paints a true picture of the patient's IOP profile. This innovative home tonometry device empowers patients to make IOP measurements during normal daily activities, offering healthcare providers a comprehensive perspective on IOP fluctuations and peaks, accessible from any location.

By leveraging the insights provided by iCare HOME2, eye care professionals can set the target IOP, tailor individual treatment plans, and review the efficacy of their intervention.

This personalized approach can enable better outcomes and improve the overall quality of patient care.

Effective control of IOP fluctuations can help slow down glaucoma progression

Setting the target IOP for patients is a crucial part of glaucoma management, and this decision heavily relies on knowing the true maximum IOP values.

Clinical studies observe that capturing real-world IOP variations and the true max value from outside of office hours can help eye care professionals in customizing glaucoma care decisions for individual patients.

A review of home tonometry by Liu et al6 presents five patient cases where iCare HOME was used in glaucoma management. iCare HOME measurement results advised further glaucoma management actions. In a recent paper by Levin et al7, the authors describe twelve cases in which home intraocular pressure (IOP) monitoring complemented peri-interventional clinical decision-making in glaucoma management.

Read what recent studies have to say about iCare HOME and how it offers easy and reliable IOP measurements to support glaucoma care.
