Lacrimal canalicular obstruction following chickenpox.

Three cases of unilateral epiphora following an attack of chickenpox were studied. Each patient was a child who was in good health prior to the onset of the attack. During the illness each had ocular symptoms suggesting local infection from the virus. A dacryocystogram revealed obstruction of the common canaliculus in each case caused by a fibrotic scar. All cases responded to appropriate surgical management.
