Abstract:Corneal thorn penetration injuries are an infrequent ophthalmic presentation. Treating them successfully depends on careful examination, surgical dexterity using the appropriate equipment and adequate post‐operative medication.
“…This may reflect the higher activity levels of young dogs, these particular breeds, and the use of certain breeds as working dogs. The tendency for working dogs to suffer from corneal FBs has been postulated in previous reports, and the presented data supported this hypothesis. Interestingly, most of the cases were seen during winter months.…”

“…For the majority of patients in this study, FB removal required general anesthesia and the use of a surgical microscope. The instrument most often used to dislodge the FB was a hypodermic needle in accordance with previous reports . The needle is used to impale the base of the thorn and move backward (i.e., in the opposite direction to the corneal penetration) .…”
Young dogs, English Springer Spaniels, Labrador Retrievers, and working dogs had an increased risk of CASFB trauma. Risk factors for enucleation were full-thickness FB penetration, severe lens trauma, and severe uveitis.

Foreign body injuries are a common reason for referral in veterinary ophthalmology and frequently cause blindness in patients with ocular trauma. Prognosis depends on the extent of the injury to intraocular structures, as well as the type and size of the foreign body. Treatment options range from conservative medical management to surgical intervention to remove the foreign body, address further ocular damage and achieve the best outcome for an animal's vision. This review summarises the types of ocular foreign bodies and their presentations in small animal practice, the role of diagnostic approaches and advanced imaging, treatment and outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
