The present study was conducted to evaluate transcorneal ultrasonographic morphometry of the eye in 21 apparently healthy Sahiwal calves of either sex. The calves were divided into three groups of seven animals each namely, Group I, II and III, comprising animals of 0 to 4 months, above 4 up to 8 months and above 8 up to 12 months of age, respectively. Ultrasonographic structures were studied and measurements of aqueous chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), sclero-retinal rim thickness (SRRT), axial globe length (AGL) and intraocular pressure (IOP) were recorded. The difference in the mean values of ACD, LT, VCD, SRRT and AGL, IOP between the right and left eyes were non-significant (p>0.05) in the calves of all the groups. The mean values of ACD, LT, VCD, SRRT and AGL increased with the age of the animal.
