:new:Title: B-mode ultrasonographic evaluation of lens equatorial length in canine cataractous eye
Author(s): Shriram Ganesan and C Ramani
Abstract: B-mode ultrasonography is one of the non-invasive, real time, rapid diagnostic imaging technique which allows evaluation of internal structures of the eye. Twenty-one dogs (35 eyes) of both sex and various breeds with the history of cataract and loss of visual acuity were scanned over this study period. The eyes were scanned under topical anaesthesia using 6-18 MHz transducer. The mean ± S.E. of lens equatorial length was 11.42±0.13 mm. There was a high degree of positive correlation between the Mean lens equatorial length and the axial length of the globe and between the Mean lens equatorial length and Axial lens thickness. The lens equatorial length could be measured using conventional ultrasound machine and the measurement could help to determine the desired haptic to haptic length of intraocular lens and appropriate size of capsular tension ring in order to prevent potential adverse effects during cataract surgery in dogs.
Keywords: Eye, dog, ultrasound, lens equatorial length, B-mode, cataract
I hope this article would be useful for Veterinary Ophthalmologists around the world for selecting appropriate size of Intraocular lens and other Intracapsular devices like capsular tension ring.:up:
