Overview and Clinical Importance
Conjunctivitis is the most common ocular disorder in cats, characterized by inflammation of the conjunctiva–the thin mucous membrane lining the inner eyelids and covering the sclera. Unlike dogs where conjunctivitis is typically secondary to other conditions, feline conjunctivitis is predominantly caused by primary infectious agents, most notably feline herpesvirus-1 (FHV-1). This distinction is crucial for the NAVLE, as it fundamentally changes the diagnostic and therapeutic approach.
The condition affects cats of all ages, breeds, and genders, though young cats in multi-cat environments are most commonly affected. Understanding the etiology, clinical presentation, and treatment of feline conjunctivitis is essential for board examination success and clinical practice.
