Clinical Impact of Measurement Timing on Intraocular Pressure in Dogs.
Dogs' eye pressure drops significantly within 5 minutes of exam start.
Clinical Impact of Measurement Timing on Intraocular Pressure in Dogs.
The objective of this study is to determine whether intraocular pressure (IOP) varies with the timing of measurement after patient presentation and whether such differences significantly affect clinical interpretation.
PROCEDURE(S): IOP was first measured immediately after history taking once the owner had left the examination room (IOP_0min).
Eye pressure fell from 16.55 to 13.06 mmHg after 5 calm minutes in the room.
Statistically significant IOP reduction was observed within all subgroups, including those divided according to sex, body weight, age, and visual status (all p < 0.001).
Females and dogs weighing > 5 kg showed greater reductions in IOP compared to males and dogs weighing ≤ 5 kg (p < 0.05).
No significant differences were observed based on age or visual status.
IOP decreases statistically significantly within minutes of patient presentation, and this reduction was observed across all subgroups.
These findings highlight that the timing of IOP measurement should be standardized to ensure an accurate and reproducible assessment, ultimately allowing for precise evaluation of the patient's ocular condition.
