The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eye and optic nerves using T 1-weighted and T 2-weighted images. A total of 6 healthy female domestic short hair cats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data were collected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, and transverse plane images were obtained from left and right eyes. Intraocular structures of the

Cornea was well detected in T 1-weighted, the iris in T 2-weighted and chiasma was well detected in T 2-weighted in dorsal plane. Measurements of the visible structures on T 1-weighted and T 2-weighted images did not show any significant difference between the left and right eyes (P>0.05). MRI provides excellent anatomical detail of the feline eye and optic nerve due to its superior soft tissue contrast and its multiplanar and multislice imaging capability.
