Lens opacities in the horse: a clinical classification

Area of Science:

• Veterinary Ophthalmology
• Equine Science

Background:

• Lens opacities, such as cataracts, are common in horses.
• Predicting the progression and visual impact of these opacities is challenging for clinicians.
• Accurate assessment is crucial for pre-purchase examinations.

Purpose of the Study:

• To develop a descriptive classification for common equine lens opacities.
• To base this classification on the morphological origin of the opacities.
• To provide a foundation for objectively predicting the progression of lens opacities, especially cataracts.

Main Methods:

• Descriptive classification of common equine lens opacities.
• Focus on morphological origin as the primary classification basis.

Main Results:

• A proposed classification system for equine lens opacities.
• The classification is based on morphological origin.
• This system offers a basis for predicting opacity progression.

Conclusions:

• The developed classification aids in predicting the progression of equine lens opacities.
• This tool is valuable for clinical assessment and pre-purchase examinations in horses.
• Improved prediction of cataract progression and visual consequences is achievable.
