5 Key Takeaways

• 1

  This retrospective longitudinal study analyzed 2,655 IOP measurements from 154 eyes of 77 patients with medically treated, stable primary open-angle glaucoma.

• 2

  In a mixed-effects model, each 1°C increase in ambient temperature was associated with a 0.029-mm Hg decrease in IOP.

• 3

  Mean blood pressure was independently and positively associated with IOP, while glaucoma type, number of eye drops, and time of day also influenced measurements.

• 4

  Temperature-related IOP decreases were significant in eyes with severe glaucoma, patients using three or four medications, and the normal-tension glaucoma subgroup.

• 5

  The authors noted the retrospective design and unmeasured factors as limitations and cautioned that findings in stable-treatment patients may not apply to poorly controlled IOP.
