“…Choroidal melanoma is very common in dogs (Fuchs and Belknap, 2018;Miwa et al, 2005). Gene mutation is the primary cause of choroidal melanoma and intraocular neoplasia in this study, which was similar to findings mentioned in other studies of dogs (Ragab and Fathy, 2018;Fuchs and Belknap, 2018).…”

“…The posterior vitreous cavity showed linear and/or curvilinear convex echos of vitreous haemorrhage (Zeiss and Dubielzig 2004;Aironi and Gandage 2009). The vitreal haemorrhage seen in 10 dogs in the current study at ultrasonography revealed subtle echogenic material floating floating within the vitreous in cases of acute vitreous haemorrhage and echogenic bands in the vitreous representing fibrous membranes in cases of chronic vitreous haemorrhage, as observed by (Ragab and Fathy, 2018).…”

Background: Ultrasonography is a simple, safe and non-invasive method to examine the internal structures of eye in case of opacity of otherwise clear ocular medium like cornea, aqueous, lens, and vitreous. Methods: 123 dogs with ocular abnormalities from March 2021 to October 2022, presented to the Division of Veterinary Surgery and Radiology were included in this study. All of the animals underwent a thorough ophthalmic examination along with B-scan ultrasonography of both the eyes using a 7.5 MHz linear probe. Result: Ultrasonography revealed thin hyperechoic lines and a thin hyperechoic rim of the lens, indicating early cataract changes and cortical cataract, respectively. Sixty-two dogs were found to be affected by cataract; 20 dogs were affected by the disease Phthisis bulbi; 16 dogs had a complete retinal detachment showing a typical “morning glory” sign; 10 dogs had vitreous haemorrhage; 6 dogs had a damaged eye with lens dislocation; and 5 dogs had choroidal melanoma and intraocular tumours in 4 dogs out of 123 observed dogs. Further, out of 62 cataract cases, 16 dogs were affected by cortical cataracts, 41 had nuclear cataracts, and 5 dogs were affected by morgagnian cataracts. Therefore, B-scan ultrasonography of the eye was a quick, safe, and accurate way to examine the pathology, especially when opaque media inhibit direct examination or when exophthalmos is evident and the normal anatomy of the eye.
