Examples are presented of patients with canalicular disease, lid abnormalities, 'functional blocks', and dysthroid disease, in which this technique was valuable. Information regarding the dynamics of a functioning and non-functioning dacryocystorhinostomy is elucidated with quantitative scintillography.
