Abstract

A 20-month-old Simmental cross bull presented to the Scottish Centre for Production Animal Health and Food Safety, University of Glasgow School of Veterinary Medicine, in April 2015 with multiple congenital ocular abnormalities including bilateral microphthalmia. We present this case as an interesting presentation of idiopathic multiple congenital ocular abnormalities in the absence of congenital abnormalities affecting other body systems. This case highlights an unusual ocular presentation and illustrates the importance of a thorough clinical examination. The prognosis for cases of multiple congenital ocular abnormalities including microphthalmia is poor as no treatment is available and welfare is often compromised. It is therefore important that cases are accurately diagnosed so appropriate management decisions can be made regarding the individual and any herd investigations that are required can be instigated.
