摘要: Reference intervals of intraocular pressure (IOP) are poorly described in piscine species as the factors that may influence it. Rebound tonometry was used to measure IOP 28 adult brook trout (Salvelinus fontinalis) anesthetized a buffered solution 60 mg/L tricaine methanesulfonate (n = 16) or restrained with electronarcosis 12) at 16 mA. There no significant effect eye side, sex, fish origin, and body weight, but values were significantly higher (mean ± SD: 16.4 5.0 mm Hg) than immersion anesthesia (10.8 3.3 Hg; P 0.0017). The same restraint method should be for comparison previously published when evaluating individual variations over time.
