Infected Meibomian Glands in Horses

The meibomian gland, also known as the tarsal gland, is vitally important in preventing the eyelids from sticking together. In horses, an infection or obstruction of the meibomian gland can cause serious problems if not identified and treated quickly.

  1. Symptoms

    • Symptoms of a clogged or infected meibomian gland include sensitivity to light, tearing, swelling and sleepiness. Horse owners should take any such symptoms seriously; horses' eyes are very sensitive and a minor injury can lead to blindness.

    Causes

    • In most cases, a meibomian condition results from a cyst or other obstruction in the duct. Other times, inflammation from an injury or infection causes the condition or makes it worse.

    Treatment

    • Sometimes meibomian problems resolve on their own with time. On occasion you will have to apply warm compresses several times a day until the blockage breaks up. In serious infections, your vet may prescribe antibiotic ointment.

    Time Frame

    • The symptoms of a blocked or infected meibomian gland can appear suddenly. Left alone, the condition may take several months to resolve, if it resolves at all. In serious cases, your horse may require surgery to repair the problem or more than one month of ointment to eliminate the infection.
