Abstract

Intraocular diseases, for instance, cataract, and blindness due to the globe diseases require precise measurement of ophthalmic parameters as these diseases may affect the treatment and management of cases. Additionally, understanding species intraocular parameters using computed tomography (CT) scanning is crucial for appropriate diagnosis. There is little literature concerning about intraocular and orbital parameters of domestic dogs. Therefore, this study aimed to describe the computed tomography features of the dog eye and its intraocular parameters dimension. Animal heads that not suffering from any diseases related to the eye were disarticulated, then a CT scan was performed. The radiodensity of the lens, anterior chamber, vitreous chamber, where density for right and left eye were (13.92, 14.49), (10.25, 11.60), (129.16, 129.64) respectively. Also, various orbital dimensions were measured. The present study's findings represent a first step toward developing CT reference values for domestic dog intraocular structural assessments.
