The sustained increase in bacterial resistance has driven the search for therapeutic alternatives that may help reduce antibiotic use, particularly in empirical treatments. In this context, topical ophthalmic antiseptics have emerged as effective and safe tools, suitable for both perioperative prophylaxis and the management of mild or superficial ocular diseases. Their broad spectrum of activity-encompassing bacteria, fungi, viruses, and protozoa-together with the low likelihood of inducing resistance, establishes them as valuable partners in daily clinical practice. This article reviews the current evidence on the use of antiseptics in veterinary ophthalmology, focusing on their clinical applications, therapeutic benefits, and limitations. It also highlights the need for further studies to establish species-specific, disease-specific, and context-based protocols.
