Why IOP Measurement Matters
Intraocular pressure (IOP) is a key indicator of glaucoma progression. Regular monitoring helps you and your doctor make informed decisions about your treatment plan.
The Office Visit Gap
Most glaucoma patients visit their ophthalmologist 1-4 times per year. During each visit, your IOP is measured once, maybe twice. That gives your doctor a snapshot, but not the full picture.
The problem? IOP fluctuates throughout the day. It's often highest in the early morning and can vary based on position, activity, stress, and medication timing. A single office reading can miss critical peaks and patterns.

IOP readings
Home monitoring doesn't replace office visits—it enhances them. You bring comprehensive data to your appointments, enabling more informed treatment decisions.
Why More Data Matters
Home monitoring with the iCare HOME2 reveals patterns that office visits can't capture.
100+ Readings vs. 1-2
Office visits: 1-2 IOP readings per year. HOME2: 100+ readings in the same period. More data means better treatment decisions.
Detect Spikes
IOP can spike at times your doctor never sees. Morning pressures, nighttime readings, and stress-related changes are all captured at home.
Track Treatment
See how well your medications are working throughout the day, not just at appointment time. Adjust dosing with confidence.
Reduce Anxiety
Waiting months between office visits can be stressful. Home monitoring gives you peace of mind and control.
When to Measure IOP
Your doctor will provide specific instructions, but common monitoring times include:
- First thing in the morning (before medications)
- Evening (to check daily fluctuations)
- Before and after taking eye drops (to assess effectiveness)
- During stressful periods or after exercise
- Post-surgical recovery periods
- Any time you have symptoms like eye pain or vision changes
Typical Protocol
Many doctors recommend measuring 3 times per eye, twice per day (morning and evening), for 1-2 weeks. This creates a comprehensive IOP profile that guides treatment adjustments.
How the HOME2 Makes It Easy
The iCare HOME2 uses rebound tonometry. A lightweight probe gently bounces off your cornea—you barely feel it. No numbing drops, no air puffs, no discomfort.
The device guides you through positioning with real-time feedback. Take 6 measurements (3 per eye), and the HOME2 automatically calculates your average IOP. Data syncs to an app that generates reports for your doctor.
Most patients master the technique within a few attempts. And if you have questions, our Patient Ambassadors—who use the device themselves—are just a call or chat away.
