Ultrasonographic findings of some ocular affections in dogs

الملخص EN

Ultrasonography is easily, safe and non-invasive method which can be used in examination and diagnosis of ocular affections which could not be diagnosed by naked eye such as cataract and intra-ocular hemorrhage.

Ultrasonography is considered as the only method for imaging the most segments of the eye globe when the light-conducting media are opaque.

In this study, twenty dogs with ocular affections were examined by eye ultrasonography of a 10 MHz micro-convex probe.

The results revealed that four cases had thin hyper-echoic lines of the lens indicating early cataract changes, three cases had thin hyper-echoic rims around the lens suggestive of cortical cataract were done.

There was one case of aphakia, which characterized by absence of the hyper-echoic posterior lens capsule.

Five cases of retinal detachment were detected and by ultrasonography, they appeared as hypo-echoic mass in an-echoic vitreal body.

Swelling in the cornea which appeared in three cases of glaucoma and the swelling appeared as an-echoic area in front to the anterior chamber.

One case of hypopyon was appeared as a hyper-echoic mass in the anterior chamber.

One case of keratitis which appear as hyper-echoic spot in cornea.

Two cases of severe iridocyclitis were noticed as the pupil appeared constricted with increased hyper-echoic, proliferated, thickening of the ciliary body.

In conclusion, ultrasonography of the eye is a safe, rapid, non-invasive and reliable method for diagnose almost eye affections.

The 10 MHz probe gave excellent quality real-time images of posterior chamber and vitreous body.
