Eye examination as part of the equine prepurchase examination

Prepurchase examination (PPE) is the most common reason for eye examination in first opinion equine practice. This paper describes a standard protocol for competent eye examination in the PPE, and reviews the interpretation of the more common clinical findings, particularly in relation to their expected influence on functional vision and their progression. The content is based on the limited existing literature, the personal opinions and experience of the author, and from discussions held with colleagues over the past 30 years.
