A user-friendly reference to basic, foundational information on veterinary ophthalmology
This book provides readers with a user-friendly manual to the basics of veterinary ophthalmology. It puts a focus on the most relevant information for clinical practice. Emphasizing canine ophthalmology, the book also covers the foundations of feline, equine, farm animal, and exotic animal ophthalmology. To aid in reader comprehension and information assimilation, a companion website presents review questions and the figures from the book in PowerPoint. Sample topics covered within the work include:
- Ophthalmic foundations: ophthalmic development and structure, physiology of the eye and vision, and ocular pharmacology and therapeutics
- Canine ophthalmology: canine orbit (disease and surgery), canine eyelids (disease and surgery), canine lacrimal apparatus (tear secretion and drainage), canine cornea (diseases and surgery) and canine glaucoma
- Other species: feline ophthalmology, equine ophthalmology, and food and fiber animal ophthalmology
- Ophthalmic and systemic diseases: comparative neuro-ophthalmology and systemic disease and the eye
Essentials of Veterinary Ophthalmology is a useful guide for veterinary students and practitioners looking to build out their core foundations of knowledge within their specific programs of study and disciplines.
