Transcorneal ultrasonographic scanning of live calf and adult healthy buffaloes (Bubalus bubalis) (n=6) were performed in an axial imaging plane to standardized the echomorphometric measurements of various ocular structures. Echo-morphological details of various intra-ocular structures were standardized. The echo-biometric studies on five parameters i.e. aqueous chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), axial globe length (AGL) and scleroretinal rim thickness (SRRT) was conducted using 6-8 MHz convex transducer at 6-9 cm scanning depth with suitable gain. The average values of ACD, LT, VCD, AGL, SRRT was 1.98±0.05, 2.99±0.09, 8.71±0.08, 11.31±0.11, 13.34±0.14, 16.06±0.20, 26.45±0.30, 33.11±0.30, 2.30±0.04 and 2.68±0.05 mm, respectively in eyes of male and females of calf and adult buffalos. Non-significant (P<0.05) difference was observed in ACD, VCD, AGL and SRRT when compared left and right eye of male as well as female of calf and adult buffalo. LT was significantly (P<0.05) higher in female than male and VCD was non-significantly (P<0.05) lower in female than male. These standard echo-morphometric details provide a benchmark to diagnose the various ocular affections.
