Corneal central and temporal thickness in rabbits

Abstract

Purpose Rabbits are largely used in experimental eye research, including investigations related to glaucoma. Thus, it is important to know some clinical parameters of this animal, such as corneal thickness. Methods Thirty eyes of 15 albinal Norfolk rabbits were evaluated, under anesthesia. Central and temporal corneal thickness were measured by ultrasonic pachimetry. Results For the right eyes the mean values of central and temporal corneal thickness were 393.40 micra (sd=18.25) and 389.07 micra (sd=22.36), respectively. For left eyes the mean values were ‐ central corneal thickness: 398.73 (sd=23.75) and temporal corneal thickness: 382.53 (sd=26.03). Conclusion It is necessary to consider the corneal central thickness in the evaluation of ocular pressure values in rabbits.
