In Brief Purpose: To evaluate current physician patterns for diagnostic lacrimal imaging in patients with epiphora related to obstruction. Methods: An invitation was sent members of the American Society Ophthalmic Plastic and Reconstruction Surgeons September 2008 participate a short web-based questionnaire. The survey focused on basic demographic information use indications various types modalities evaluation epiphora. Specific queried included facial x-ray, ultrasound, CT, MRI, contrast dacryocystography, radionuclide dacyroscintigraphy. Responses were analyzed using standard statistical methods. Results: Less than 5% respondents any type majority their thought due When used, CT most common overall. preferred modality all surveyed when an elected, except confirming site or obstruction which case dacryocystography preferred. Excluding indicated that they "never" (0%) used specific studies surveyed, including dacyroscintigraphy, never by over 75% respondents. Conclusions: low overall rate suggests problems are diagnosed office testing alone. For indications, preference CT. No difference frequency found our considering external versus endonasal dacryocystorhinostomy. Most favored approach secondary study group low. indications.
