Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus). [PDF]

open access: yesVet Ophthalmol
ABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),
