(B) Symblepharon, or adhesion of the conjunctiva to the eyelids, the cornea, and to itself, in this kitten is obscuring visualization of a normalsized globe. The cornea undergoes rapid desiccation with malacia, and perforation is likely if not addressed promptly. Conjunctivitis with chemosis of the ventral conjunctiva is present. (C) Apocrine hidrocystomas present as single to multiple masses often cystic and containing brown proteinaceous fluids as in this Persian cat. Treatment is the same as for the dog.

Eyelid agenesis or lid coloboma is an infrequent disorder in kittens, affecting one or both eyelids (Figure 14.5). Note the multiple sites of involvement (e.g., nose, forehead, and eyelids). Microphthalmia has been observed in three kittens in one litter of a queen who had been treated throughout gestation with the antifungal agent griseofulvin.180 Microscopic examination of the orbital tissues revealed remnants of retinal neuroepithelium, indicating that an optic cup had formed in the embryo. The prognosis for the return of vision in cats is poor. Often, ophthalmic examinations can assist in timely identification of the systemic disorder. These often appear as areas of focal alopecia.

Microphthalmia is a rare condition in kittens, but often these globes have multiple anomalies (Figure 14.1). In one in every 10,000 births, a child may suffer vision loss as a result of the condition. In contrast to dogs, lid tumors in cats are highly malignant, locally infiltrative, and often require extensive surgery or a combination of therapies (surgical debulking, cryotherapy, radiation, and chemotherapy).

Bilateral microphthalmia is a rare congenital condition that is characterized by the abnormal development of both eyes. I am adopting a 6 month old tortie tomorrow and she only has one eye and that has very limited vision. As the orbital space is more limited in cats, orbital inflammations rapidly cause protrusion of the nictitans, conjunctival hyperemia, localized orbital pain, and limited exophthalmos (Figure 14.3).

Tear and nasolacrimal disorders in cats are infrequent, but keratoconjunctivitis sicca (KCS) does occur. About 90% are malignant, and about 60% of these tumors are squamous cell carcinomas (Figure 14.4). The conjunctivitis is characterized by conjunctival hyperemia, chemosis, and serous to later mucopurulent conjunctival exudates. } In contrast to dogs, lid tumors in cats are highly malignant, locally infiltrative, and often require extensive surgery or a combination of therapies (surgical debulking, cryotherapy, radiation, and chemotherapy). Of note, the term "clinical anophthalmia" refers to what .
