title: Alacrima.
abstract: Alacrima, a congenital lack of tears, is a comparatively rare condition. Seven cases are presented, and the possible aetiology discussed. All cases should be followed up in view of the possible development of the full sicca syndrome later in life. Alacrima should be considered as an underlying condition in cases of red irritable eyes in young children, even in the absence of a definite history from the parents.
