Ansari Mood M, Rajaei SM, Hashemi SS, Williams DL. MEASUREMENT OF INTRAOCULAR PRESSURE IN THE DOMESTIC PIGEON (COLUMBIA LIVIA). J Zoo Wildl Med. 2016;47(3):935-938.
The purpose of this study was to establish intraocular pressure values in clinically normal pigeons. One hundred (52 male and 48 female) healthy pigeons ( Columbia livia ) of six different breeds, ranging in age from 20 to 51 mo were used in the study. Pigeons were gently physically restrained in a dorsoventral position without any pressure or extension to the head and neck. A rebound tonometer with a disposable probe was held horizontally and 4-5 mm from the central corneal surface. Calibration of the device was set to "P. " Overall, the mean ± SD intraocular pressure values of all eyes were 6. 1 ± 0. 9 mmHg (ranging from 3 to 9 mmHg). Mean ± SD values for left and right eyes were 6. 1 ± 1. 0 and 6. 0 ± 1. 2 mmHg, respectively. There was no statistically significant difference in IOP between the left eye and right eye or between males and females (P = 0. 49; P = 0. 74). ANALYSIS
of variance revealed that there were no significant differences in the IOP between the breeds (P = 0.22).
