Computed tomographic dimensions and densities of the normal eye in Jeju horses.

The research focuses on detailing the computed tomographic (CT) dimensions and contrast attenuation of the eye in Jeju horses and Thoroughbreds, revealing significant differences between the two breeds in various measurements.

Objective of the Study

• The fundamental goal of the study was to describe and compare the computed tomographic (CT) dimensions and contrast attenuation (how much x-ray beams decrease in intensity) of the eyes between Jeju horses and Thoroughbreds.

Methodology

• Using CT imaging technology, researchers conducted an evaluation of the ocular (eye) dimensions and contrast attentuation of 10 Jeju horses and 6 Thoroughbreds which had no prior ocular abnormalities.

Measurements

• The following parameters were measured in both breeds: diameter of the lens, globe (the eyeball without the appendages), posterior segment (the back third of the eye), orbital fossa (the cavity or socket of the skull in which the eye and its appendages are situated), lateromedial distance of the anterior chamber (front part of the eye), and the Hounsfield units of the vitreous body (part of the pixel density).

Study Findings

• A significant difference was found between Jeju horses and Thoroughbreds in all the aforementioned measurements (P<0.05), indicating a variation in the ocular structures between the two breeds.

Contribution to the Field

• This study provides detailed information regarding the CT anatomical characteristics of the eyes of Jeju horses and Thoroughbreds, as well as the differences between the two breeds. This information can be useful in understanding and evaluating the eyes of Jeju horses via CT scans, aiding in better diagnosis and treatment of ocular conditions in these breeds.
