What is The Effect of Body Position on Intraocular Pressure in Anesthetized Horses about?

## Abstract ## Objective To evaluate the effect of four recumbent body positions on intraocular pressure (IOP) in anesthetized normal horses. ## Animals studied Ten nonglaucomatous adult horses. ## Procedures Intraocular pressure was measured with a rebound tonometer in both eyes of standing sedated horses (baseline), then under general anesthesia during four randomized recumbent body positions, including Trendelenburg (Tr; 15‐degree head down), reverse Trendelenburg (RTr; 15‐degree head up), dorsal, and lateral; only the superior eye was measured in lateral positions. The mean of 3 IOP readings was taken at each position, allowing a minimum of 2 minutes of acclimatization after each position change before obtaining measurements. Repeated Measures Analysis with Newman‐Keuls Multiple Comparison Post hoc was used to compare IOPs in different positions, and linear regression was used to compare IOP with age and weight cofactors. ## Results When compared to baseline, the greatest change in IOP occurred in Tr (increase of 25.63 ± 8.12 mm Hg). When comparing all recumbent positions to baseline, IOP significantly increased in 3 of 4 body positions (P < .001), with no significant differenc
