Congenital fistulae of the lacrimal gland.
A 15-year-old female was found on routine clinical examination to have bilateral asymptomatic congenital fistulae of the lacrimal glands. The fistulae opened into the conjunctival sac at the external canthus of both eyes. Temporary occlusion of these openings produced an immediate and significant reduction in tear secretion in both eyes.
