Abstract

In this study, 55 patients (104 eyes) were studied in order to assess tear drainage, using a computer assisted gamma camera. Twentynine eyes had DCR, 29 eyes had CDCR with Jones' tube, and remaining 46 eyes were considered controls. We measured T1/2 values, the time in which a given amount of tracer drops to half in the conjunctival sac area. The time values were classified into 4 groups; Group I (3 min or less), Group II (3-6min), Group III (6-9min) and Group IV (9min or longer). In the patients with DCR and CDCR, tear drainage was faster than in the control group. Age was considered as a factor of delayed tear flow in those patients with DCR and controls, however, it was not a relevant factor in those patients with CDCR using Jones' tube.
