The objective of this study was to evaluate the intraocular pressure (IOP) of healthy Criollo horses using a rebound tonometer throughout the day. In addition, assessments were made in horses of different ages. Twenty-seven horses, male and female, were divided into three groups by age: Group I (3–5 years old), Group II (6-8 years old), and Group III: (9-16 years old). Ophthalmic examinations were performed using the Schirmer tear test, slit-lamp biomicroscopy, fluorescein test and indirect ophthalmoscopy. Seven measurements of IOP were assessed on the same day (at 6:00 am, 9:00 am, 12:00 am, 3:00 pm, 6:00 pm, 9:00 pm and 00:00 pm). A t-test was used when there were two groups of comparisons and ANOVA was used to detect differences in IOP between measurement times and between age categories. The average IOP was 28.4 ± 3.7 mmHg for all eyes. The mean IOP for Groups I, II and III were 29.2 ± 3.5, 28.4 ± 4.3 and 27.7 ± 3.2 mmHg, respectively. There was no statistically difference between right and left eyes. There was a significant difference between Group I and Group III (P = 0.008). There were no statistically significant differences between measurements recorded at different times of the day (P = 0.560). The IOP was not influenced by the circadian rhythm, but older horses showed reduced IOP.References
