An ocular response analyzer is a device that measures eye pressure and corneal biomechanics in more detail.
How the ocular response analyzer works
Similar to a puff test, it sends a rapid air pulse to the cornea. Sensors then record how the cornea bends in and out, giving information about its stiffness and true pressure.
- The test is quick and non-contact, using air rather than instruments
- It provides two pressure readings and corneal hysteresis values
- Results are especially helpful in glaucoma assessment
- You can resume normal activities immediately afterwards
Benefits of this advanced measurement
Corneal properties can affect standard pressure readings. Understanding these factors helps the clinician judge your real risk of optic nerve damage more accurately.
- Useful for patients after laser vision correction or with unusual corneas
- Supports tailored treatment decisions in glaucoma care
- Helps track changes in corneal biomechanics over time
- Can be combined with other tests for a complete risk profile
