Abstract
The echo-biometrical evaluation of normal eye was done in 20 Gaddi goats with the help of ultrasonography at Gaddi goat unit, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. Trans-corneal and trans-palpebral ultrasound scanning of the normal eye was done in standing position without any sedation or regional nerve block. Xylocaine ointment (5%) was used to desensitize the cornea and 2% lignocaine jelly was applied directly on the cornea to serve as a conductive medium for ultrasound waves in trans-corneal technique. B-mode ultrasound scan of the eyes was done in both the transverse and sagittal planes. Corneal thickness varied from 0.03 to 0.07 cm, aqueous chamber depth from 0.12 to 0.31 cm, lens thickness from 0.78 to 0.96 cm, lens diameter from 0.92 to 1.36 cm, vitreous chamber depth from 0.90 to 1.08 cm, eyeball diameter from 1.90 to 2.66 cm and eyeball length from 1.90 to 2.12 cm. There was no statistically significant difference between the echo-biometric parameters of the left and right eye in the present study.
