Abstract:
Ultrasonography is a non-invasive diagnostic imaging procedure that uses sound waves to capture images of interior eye. Direct visualization of intraocular structures is difficult or impossible when eyelids are swollen shut after injury. Moreover, lens opacification and hyphema can also block the posterior view of the chamber. Twenty dogs presented at TVCC, Jabalpur, suffering with ephiphora, decreased visual acuity and failed obstacle course test were evaluated with routine ophthalmological examination and B mode ultrasound scan of both the eyes to reveal vision threatening conditions such as pigmentary keratitis, various grades of cataract, lens luxation, vitritis and retinal detachment. Typical ultrasound images showed complete reflection of sound wave from corneal surface in case of pigmentary keratitis, hyperechoic lens capsule and lens in cataract, luxated hyperechoic lens lying in hypoechoic vitreous humor, hyperechoic foci in anechoic vitreous in case of vitritis and finally sea gull appearance of retina in case of retinal detachment. Therefore it can be concluded that ultrasonography is an effective diagnostic tool along with the ophthalmoscopy to diagnose internal structures of eye.
