Figure 1.

Purulent conjunctivitis with corneal opacity of the right globe of a mule deer (case 7). Abundant purulent exudate is adhered to the eyelids and conjunctiva. The cornea is diffusely opaque. This lesion was bilateral and was associated with infection by herpesvirus and Actinomyces sp. Figure 2. Purulent keratoconjunctivitis of the left globe of a mule deer (case 3). The cornea is diffusely thickened by purulent exudate, fibrin, and neovascularization with hyperemia. Purulent exudate is adhered to the lower eyelid and medial canthus. This lesion was unilateral and associated with infection by Trueperella pyogenes. Figure 3. Focal corneal ulceration with purulent conjunctivitis of the right globe of a mule deer (case 10). The cornea is diffusely opaque with a central area of ulceration flanked by a rim of neovascularization. Purulent exudate is seen along the eyelids. Moraxella ovis was cultured from this lesion, which was bilateral. Figure 4. Proliferative keratitis of the left globe of a mule deer (case 1). The center of the cornea is markedly thickened by a focally extensive, raised lesion composed of granulation tissue. No pathogens were cultured from this lesion; severe panophthalmitis associated with Trueperella pyogenes was seen in the contralateral globe.
