PURPOSE
To compare the usefulness of fluorescein dye disappearance test (FDDT) and dacryoscintigraphy in functional lacrimal blockage. METHODS: The present study included with 24 patients (37 eyes), who were diagnosed with functional lacrimal blockage and underwent silicone tube insertion in our clinic. Compared to postoperative symptom improvement, the results of FDDT and dacryoscintigraphy were analyzed. RESULTS: Significant correlations were observed with FDDT and dacryoscintigraphy results in 29 eyes before surgery. In 33 eyes, there were post-operative symptom improvements and the sensitivity of each exam was estimated at 87.8% in FDDT and 90.9% in dacryoscintigraphy. After intubation normal findings were observed in each examination and the symptoms improved in 7 out of 8 eyes. CONCLUSIONS: Both FDDT and dacryoscintigraphy were considered sensitive and efficient methods in the diagnosis and evaluation of functional lacrimal blockage. Both methods require caution regarding misinterpretation by false negatives and may be complementary as well as increasing diagnostic accuracy. |
