RESUMEN
Background: Intra-lenticular foreign bodies are rare in veterinary medicine and uncommon in human medicine. Approximately 50% of perforating ocular injuries in canines have lenticular involvement. Treatment choices include conservative management and surgical options. Retained intra-lenticular foreign body with delayed removal has not been reported in animals. Case Description: A 3-year-old male neutered Lurcher presented with right-sided ocular discomfort and a sealed full-thickness corneal perforation. The full ophthalmic examination could not be performed at the initial presentation due to miosis. Recrudescence of anterior uveitis was seen post-drug cessation. Re-evaluation of the eye with a mydriatic pupil revealed an intra-lenticular foreign body. Surgical removal via phacoemulsification was performed 8 weeks after the initial perforating injury. The eye remains visual, comfortable, and normotensive 50 months post-operatively. Conclusion: This is the first report of an encapsulated, retained intra-lenticular foreign body with delayed removal in a dog. Mydriasis and repeat examinations are of crucial importance when evaluating eyes post-perforation.
