Measuring intraocular pressure (IOP) has been a cornerstone of glaucoma care for decades. Glaucoma affects an estimated 76 million people worldwide, and that number is projected to exceed 110 million by 2040. Because vision loss caused by glaucoma is permanent, early detection and routine monitoring remain critical (Tham et al., 2014).
For years, Goldmann Applanation Tonometry (GAT) has been considered the gold standard for measuring eye pressure. But as eye care practices become busier and technology continues to evolve, many clinicians are exploring newer methods that improve efficiency while still providing reliable clinical information.
One technology gaining attention is transpalpebral tonometry.
What Is Transpalpebral Tonometry?
Unlike traditional tonometers that measure pressure by contacting the cornea, transpalpebral tonometry measures intraocular pressure through the upper eyelid.
Because the cornea isn't touched, the procedure does not require topical anesthetic drops or fluorescein dye. The result is a faster, simpler measurement process that may fit well into many modern practice settings.
Why Are More Practices Considering It?
Every minute matters in a busy clinic.
Traditional applanation tonometry is highly respected, but it also requires a slit lamp, corneal contact, topical anesthetic, and fluorescein before a measurement can be taken. While these steps are appropriate in many situations, they can add time to the examination process.
Transpalpebral tonometry offers a different approach by allowing clinicians to measure intraocular pressure:
-Without touching the cornea
-Without anesthetic drops
-Without fluorescein dye
-Using a lightweight handheld device
-In approximately 1–2 seconds
For practices that value portability and workflow efficiency, these features may provide meaningful day-to-day benefits.
What Does the Research Show?
As with any diagnostic device, clinical evidence matters.
A 2024 peer-reviewed study published in Medicina compared the Easyton Transpalpebral Tonometer with the Goldmann Applanation Tonometer, Tono-Pen AVIA, and Icare 200 in healthy adults.
Researchers found that the Easyton demonstrated excellent inter-observer reliability, meaning different trained clinicians obtained consistent measurements with the device. The study also confirmed that the Easyton measures through the eyelid without direct corneal contact or the need for topical anesthetic or fluorescein. While the Easyton generally recorded slightly higher IOP values than Goldmann Applanation Tonometry, the authors concluded that it can be useful when traditional applanation tonometry is not feasible, emphasizing the importance of understanding the device's measurement characteristics in clinical practice (Kizilay et al., 2024).
Could the Easyton Be a Good Fit for Your Practice?
No single tonometer is the right choice for every clinic. The best option depends on your workflow, patient population, and clinical preferences.
Since measurements are taken through the upper eyelid, many clinicians also appreciate the more comfortable experience this approach can provide for patients compared with methods that require direct corneal contact.
