Key Highlights
- A retrospective study included 77 patients and 154 eyes, with 2,655 Goldmann applanation tonometry measurements over an average of 5.2 years.
- Each 1°C increase in ambient temperature was associated with an estimated 0.029 mmHg decrease in IOP; daily temperature analysis showed a similar association.
- Mean blood pressure, glaucoma type, number of eye drops, and time of day also significantly influenced IOP measurements.
- Temperature associations were significant in severe-stage glaucoma, normal-tension glaucoma, and patients using three- or four-drug regimens.
- The authors cautioned that the findings may not apply to patients with poorly controlled IOP or changing medication regimens.
Guideline-Based Recommendations
Diagnosis
Management
- The authors conclude that ambient temperature should be considered as an independent factor in IOP measurements when developing a more comprehensive approach to POAG management.
Monitoring & Follow-up
- The authors suggest that ambient temperature may be worth considering when interpreting longitudinal IOP measurements, particularly in patients with more advanced glaucoma.
Risks
- The study was retrospective and did not account for factors including exercise, obesity, and blood biochemistry.
- The study included patients with stable medication regimens; the authors cautioned that findings may not extend to individuals with poorly controlled IOP.
- The high-tension glaucoma subgroup was small; the authors noted that its nonsignificant result could reflect insufficient statistical power.
Patient & Prescribing Data
77 patients aged over 40 with medically treated POAG; medication regimens remained unchanged during follow-up.
The temperature association was significant among patients receiving three- or four-drug regimens. All included patients remained on unchanged medication regimens during follow-up.
Clinical Best Practices
- The authors suggest considering ambient temperature when interpreting IOP measurements; the study also found associations with mean blood pressure, glaucoma type, number of eye drops, and time of day.
- The reported temperature association was observational and was found in patients with stable treatment.
