Purpose: We determined whether naturally-occurring lenticular myopia in English Springer spaniels (ESS) has a genetic component.

Methods: Streak retinoscopy was performed on 226 related ESS 30 minutes after the onset of pharmacologic mydriasis and cycloplegia. A pedigree was constructed to determine relationships between affected offspring and parents.

Objective: To compare the diagnostic quality of computed tomography (CT) images of normal ocular and orbital structures acquired with and without the use of general anesthesia in the cat.

Animal Studied: Eleven privately owned cats with nasal disease presenting to a single referral hospital.

Procedures: All cats received a complete ophthalmic examination.

Objective: To determine the characteristics of, prevalence of, and risk factors for corneal pigmentation (CP) in Pugs.

Design: Prospective cross-sectional study.

Animals: 295 Pugs > 16 weeks old.

Canine ocular neoplasia: a review.

Ocular neoplasia is relatively rare in dogs but can have significant impact on vision, comfort, and longevity. Prognosis for life and for the globe varies with tumor type. In this review, the clinicopathologic features of the most common canine ocular neoplasms are detailed, with emphasis on histologic and immunohistochemical characteristics.

Anesthesia for ophthalmic procedures in the standing horse.

Effective delivery of local anesthesia is essential for successful standing surgical procedures in the horse. Local anesthesia can be used to facilitate examination of the eye, diagnostic procedures, therapeutic techniques, and surgical procedures. Understanding the relevant clinical anatomy and techniques for performing local anesthesia is critical to delivering successful local and regional anesthesia and analgesia.

Canine ocular onchocercosis in the United States is associated with Onchocerca lupi.

Canine ocular onchocerciasis has a worldwide distribution and has been associated in Europe with Onchocerca lupi based on morphologic and molecular analysis. In the United States, canine ocular onchocerciasis is reportedly associated with Onchocerca lienalis. This association is based solely on histopathologic examination of ocular tissues.
