Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) ; Processo FAPESP: 05/59086-5 ; Processo FAPESP: 07/06519-7 ; ObjectiveTo determine ultrasonographic and echobiometric findings in the eyes of goats of different ages. B and A mode ultrasonography was performed in 55 healthy Saanen goats (110 eyes) of ages 45 (n = 15), 180 (n = 20), and 549 days (n = 20).ProceduresTranscorneal ultrasonography was performed after instillation of a topical anesthetic and application of acoustic transmission gel on the 20-MHz linear transducer tip. The transducer was placed in a longitudinal position until optimal B scan images, according to echoes of A mode images, were obtained. Statistical analysis was carried out to compare the echobiometric readings among subjects (P
