Which ocular disease can sulfa drugs cause?

Keratoconjunctivitis sicca (KCS), also known as dry eye, can be caused by the use of sulfa drugs in certain cases. Sulfonamides may lead to a decrease in tear production by affecting the lacrimal glands, which are responsible for producing the aqueous layer of tears. The reduction in tear secretion results in inadequate lubrication of the ocular surface, leading to dry eyes and inflammation of the conjunctiva, commonly associated with KCS.

Understanding the side effects of medications such as sulfa drugs is important in veterinary practice, as it emphasizes the need for careful monitoring of patients on these drugs. It's crucial for veterinarians to recognize potential adverse effects and to manage the complications effectively, ensuring the well-being of their patients.
