A per­sis­tently wa­tery eye

EQUUS - - Eq Inbrief -

Some­times co­pi­ous, per­sis­tent tears sig­nal a com­mon and usu­ally harm­less equine eye prob­lem: a blocked tear duct.

Tech­ni­cally known as na­so­lacrimal ducts, these tiny pas­sages al­low tears to drain from the eye down through the nos­trils. If the ducts be­come clogged with mu­cus or other ma­te­rial, tears col­lect and spill over the bot­tom lid of the eye.

To clear the block­age, a vet­eri­nar­ian will run a small tube up through the horse’s nose and flush saline through the chan­nel. Af­ter a tear duct is flushed, it may never be­come clogged again, but some horses are prone to block­ages and it may be best to sim­ply leave them. When that’s the case, how­ever, it’s im­por­tant to pro­tect the area be­low the eye against scald­ing with a thin layer of petroleum jelly and to use a mask against flies, which will be drawn to the mois­ture.
