Optimmune is an eye ointment for dogs indicated for the management of chronic keratoconjunctivitis sicca (KCS) and superficial keratitis. KCS or dry eye is an eye condition that results from an inadequate quantity of tears or a deficient quality of tears. Tears are produced by the tear gland and the gland of the third eyelid. Tears provide lubrication and nutrition to the cornea and remove debris and infectious agents from the eye. Superficial keratitis or Pannus is an inflammation of the cornea that causes opacification and, eventually, visual impairment. Both eye conditions are the result of an immune system disorder. Optimmune contains Cyclosporine, an FDA-approved anti-inflammatory, immunosuppressive medication that reduces swelling and irritation and helps increase tear production. Optimmune will relieve your dog’s discomfort by easing swelling, dryness, and pain.
