Abstract
This research aims to
investigate the impact of body position, eyelid manipulation, and jugular vein
compression on intraocular pressure in healthy horses. Seven healthy horses,
including both male and female, aged between 5 to 8 years, and weighing between
250 to 350 kilograms, were selected. After thorough examination and
confirmation of the horses' health, intraocular pressure was measured using
rebound tonometry. Initially, baseline intraocular pressure was measured with
the head positioned horizontally relative to the ground and without any
pressure on the neck or eyelid. Subsequently, five manipulation conditions were
applied to each eye, including unilateral jugular vein compression, bilateral
jugular vein compression, eyelid dorsal-ventral traction, eyelid lateral
traction, and external eye compression. After completing the manipulations,
intraocular pressure was measured in the head-up position. The obtained data
results were statistically analyzed using the T-Student method. The mean
intraocular pressure in baseline, unilateral compression, bilateral compression,
eyelid dorsal-ventral traction, eyelid lateral traction, head position, and
external eye compression conditions were 76.4 ± 23.86 mmHg, 29.5 ± 26.93 mmHg,
80.5 ± 30.49 mmHg, 83.5 ± 32.78 mmHg, 96.4 ± 27.43 mmHg, 99.4 ± 27.28 mmHg, and
20.5 ± 27.21 mmHg, respectively. The results indicated a significant difference
(p<0.05) only in the left eye intraocular pressure values between BJC and DE
treatments compared to the Baseline treatment. Conversely, a significant
difference (p<0.05) was observed in the right eye intraocular pressure
values between all treatment conditions and the Baseline treatment. Unilateral
jugular vein compression, bilateral jugular vein compression, eyelid
dorsal-ventral traction, head position, eyelid lateral traction, and external
eye compression exerted an effect on intraocular pressure in horses, leading to
its increase.
