![]() ![]() Replacement of the globe and short‐term complete temporary tarsorrhaphy should be performed as soon as possible. The prognosis for successful globe replacement and return of vision is very poor. The pupil is dilated and unresponsive to light. Note the marked drying and desiccation of the unprotected cornea. ![]() Damage to the contralateral optic nerve can result in blindness of the fellow eye.įigure 14.2(A) Marked proptosis in a cat of several hours duration. Optic nerve damage (extending to involve the optic chiasm) can be a complication from the trauma with stretching and inflammation. The cornea undergoes rapid desiccation with malacia, and perforation is likely if not addressed promptly. Orbital hemorrhage can compound the globe luxation. It is usually associated with considerable head trauma, and often mandibular symphysis fractures are present. Proptosis or the traumatic displacement of the eye from the orbit is a serious disease in the cat ( Figure 14.2). (B) Symblepharon, or adhesion of the conjunctiva to the eyelids, the cornea, and to itself, in this kitten is obscuring visualization of a normal‐sized globe. The microphthalmia causes the exposure of the dorsal sclera within the palpebral fissure. Generally there is no treatment.įigure 14.1(A) Microphthalmia affecting both eyes in a kitten. Vision is usually present unless the cataract formation is advanced. Breeds affected include the Domestic Shorthair and Persian. Microphthalmia is a rare condition in kittens, but often these globes have multiple anomalies ( Figure 14.1). ![]()
