  • Presented to ES for redness and squinting, OD. History of glaucoma, OD.
  • On physical exam, the dog had hyphema (anterior chamber) hindering further evaluation.
  • Ultrasound of the eye was performed to further evaluate the clinical signs.
  • The lens is highly echogenic.
  • Retinal detachment is characterized by the typical V-shaped hyperechoic lines in the posterior globe, attaching to the ora serrata and optic cup.
  • Echogenic fluid posterior and anterior to the retina suggests hemorrhage.
  • Anterior bowing of the iris with circumferential adhesion of the iris to the lens, iris bombe.
  • Cataracts, retinal detachment, echogenic vitreous (hemorrhage), iris bombe.

Hereditary chronic uveitis, with subsequent cataract, and retinal detachment. At some point the eye developed PIFM (pre-iridofibrovascular membranes) that bleed and predispose the dog to glaucoma and spontaneous hyphema.

Iris Bombe is an acute increase in posterior chamber pressure caused by apposition of the iris (synechia or adhesion) to the lens or other parts of the eyeball, preventing aqueous flow from posterior to anterior chamber.

The dog was treated medically for glaucoma. The owners were not interested in further therapy. Over time there has been less ballooning of the iris. The hyphema still waxes and wanes. The eye is not visual.
