title: Primary tuberculosis of the conjunctiva.
abstract: A five-year-old boy developed primary tuberculosis of the conjunctiva which spread to the preauricular and cervical lymph nodes, producing caseous lymphadenitis. Because conjunctival tuberculosis is rare, the correct diagnosis may be easily missed. When unilateral conjunctivitis is accompanied by lymph node enlargement and persists or progresses, tuberculosis should be suspected.
