Hypothesis
The rate of index therapy change would be lower with travoprost-Z preserved with SofZia than with latanoprost preserved with BAK.
Conclusion
Medication changes were common in both treatment groups but statistically significantly more frequent with travoprost-Z.
Supporting Evidence
- Patients treated with travoprost-Z were 52% more likely to change therapy within the first six months.
- Insufficient IOP control was the most commonly reported reason for therapy change.
- Hyperemia was reported significantly more frequently among those treated with travoprost-Z.
Takeaway
Doctors looked at patient records to see how often people had to change their eye medicine. They found that more people had to switch from travoprost-Z than from latanoprost.
Methodology
A retrospective chart review was conducted at 14 clinical practice sites, analyzing medical records of patients with open-angle glaucoma or ocular hypertension who were treated with latanoprost or travoprost-Z.
Potential Biases
No formal tests of reliability were undertaken for chart abstraction across sites.
Limitations
The follow-up time frame was too short to support assessments of changes in parameters such as visual field.
Participant Demographics
Patients were ≥40 years of age, with a median age of approximately 67 years, and >50% were female.
