Plain-English summary
A young Samoyed, a Spanish Pachon, and a mixed breed dog were diagnosed with serious eye problems due to a condition called persistent hyperplastic primary vitreous (PHPV), which can lead to various ocular complications. The Samoyed had bleeding in one eye, while the Spanish Pachon experienced glaucoma and inflammation, along with other eye issues. The mixed breed dog showed signs of small eyes and other abnormalities in both eyes. Advanced imaging techniques helped veterinarians identify cataracts and other serious conditions in these dogs. Treatment options would depend on the specific issues found, but early diagnosis is crucial for managing these eye problems effectively.

Abstract
Persistent hyperplastic primary vitreous (PHPV) syndrome associated with either severe ocular complications or multiple ocular lesions was diagnosed in three young dogs, a Samoyed, a Spanish Pachon, and a mixed breed dog. Due to opacification of the anterior ocular structures, B-mode and color-flow Doppler ultrasonography were performed to aid diagnosis. The Samoyed presented with unilateral hyphema; the Spanish Pachon presented with unilateral secondary glaucoma associated with uveitis and hyphema OD and leucocoria OU; and the mixed breed presented with bilateral leucocoria. B-mode ultrasonography of the Samoyed revealed a subcapsular cataract and a hyperechoic tubular structure attached from the optic disk to the posterior lens capsule. In the Spanish Pachon B-mode ultrasonography of the right eye indicated microphakia, cataract formation, and a retrolental mass with a thin hyperechoic strand stretching from the optic disk to the posterior lens; and for the right eye cataract formation, PHPV, retinal detachment, and vitreous hemorrhage. In the mixed breed dog, B-mode ultrasonography of both eyes indicated microphthalmia, retrolental mass, and hyperechoic lenses. By color-flow Doppler imaging, blood flow was present in the retrolental mass of the right eye suggesting a persistent hyaloid artery.
