Ultrasonographic anatomy of the goat eye

Abstract

Domestic goats (Capra hircus) are a ruminant species important in the economy of several countries. Considering the health implications and the economic potential of goats, the issue of investigating the clinical characteristics of goat's eye is of considerable relevance. In goats, Pinkeye (keratoconjunctivitis) is the inflammation of the inside of the eyelid and considers as a highly contagious infection that spreads through contact, outbreaks frequently occur when new goats are introduced to the herd. So this study aimed to report the normal echobiometric anatomy of Iraqi goats' eye in order to know the clinical aspect of the ocular structures and the normal range of ocular parameters by using the sonographic machine. Ocular echobiometric inspections were achieved on 20 goats (10-14 months old) from local breed. Ultrasonographic images were obtained with a 7.5 MHz linear probe in the sagittal plane. Results showed; that the axial globe length (AGL) was (20.4±0.2mm), anterior chamber depth (ACD) (1.98±0.14mm), vitreous chamber depth (VCD) (9.85±0.12mm), sclera-retinal rim thickness (SRT) (1.6±0.08mm), lens thickness (LT) (7.77±0.22mm) and corneal thickness (CT) (0.59±0.01mm) respectively. The estimated dimensions of the normal ocular components which gained from this study by using sonographic machine give an eminent schedule to veterinarians in the appraisal of ocular diseases in goats.
