Abstract:
The present study was conducted to record changes in intraocular measurements in dogs affected with cataract using real time B-mode ultrasonography and comparing the change in ocular biometry with normal eyes. Transcorneal ultrasonography using excess coupling gel as standoff pad was performed by immersion technique with a 7.5 MHz sector probe. A total of 50 eyes (40%) affected with cataract were subjected to B-mode ocular ultrasonography and various ocular biometric parameters were measured. There was a significant increase (p<0.05) in corneal thickness in eyes affected with incipient cataract when compared to normal eyes. The intumescent cataracts have significantly reduced (p<0.01) anterior chamber depth and increased lens thickness (p<0.01) while hypermature cataract have significantly increased (p<0.01) anterior chamber depth, reduced lens thickness (p<0.01) and reduced lens equatorial length (p<0.05). Lenses with mature cataract and incipient cataract showed a trend towards increased lens thickness and immature cataracts demonstrated a trend towards reduced lens thickness with non significant difference.
