Non-contact tonometry (NCT) can underestimate eye pressure, while Goldmann applanation tonometry (GAT) is more accurate and used for treatment decisions. A GAT reading of 20 indicates that your eye pressure is still borderline high, so you should discuss these results with your eye doctor to see if further tests or adjustment of your medicines are needed.

Understanding IOP Measurement Differences
- Non-Contact Tonometry (NCT) and Goldmann Applanation Tonometry (GAT) can show different readings. GAT is the gold standard for IOP measurement.
Current Medication Overview
- Ganfort (timolol + bimatoprost) and Azopt (brinzolamide) help lower IOP. You are on multiple medications, indicating active management.
Interpretation of Your IOP Readings
- An IOP of 20 mmHg by GAT is significant. Target IOP depends on individual risk factors and optic nerve health.
Recommended Next Steps
- Consult your ophthalmologist to review your treatment plan. Consider repeat GAT measurements and additional tests like visual field analysis and optic nerve imaging. Discuss potential medication adjustments if IOP remains high.
Importance of Regular Monitoring
- Regular follow-up visits are crucial to monitor IOP and eye health. Adhere to prescribed medications and report any side effects or vision changes promptly.
When to Seek Immediate Care
- Seek urgent attention for symptoms like sudden vision loss or eye pain.
