Dendritic or microdendritic corneal ulcers result, which stain poorly with topical fluorescein but fairly well with rose Bengal. Corneal sequestration appears as a variable shaped, size, and depth, brown to black lesion that may be so dense that slit lamp biomicroscopy cannot accurately estimate the depth of stromal involvement. Note the multiple sites of involvement (e.g., nose, forehead, and eyelids). Coming into contact with, or ingesting, an infected animals fecal matter. Structural abnormalities of the eyelids (i.e., entropion and ectropion) are infrequent in cats, but entropion occurs in the Persian and other brachycephalic breeds, in tom cats of any breed that were neutered later in life, or in an aged or infirm cat that has had significant weight loss or atrophy (Figure 14.6).

(D) Cutaneous mast cell tumors have been reported in the eyelids of cats. 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). Figure 14.14 (A) Symblepharon in a cat associated with FHV1. Microphthalmia occurs when a canine is born with an eye that is smaller than normal; this is a disorder related to development.
