Evaluation of Distal Occlusions accompanying Punctal Stenosis using Radionuclide Imaging in patients with Unilateral Epiphora

Objective: Our objective was to evaluate distal occlusions accompanying punctal stenosis, which can lead impaired nasolacrimal drainage in patients with using radionuclide imaging. Material and Methods: study enrolled 42 who had unilateral stenosis experienced epiphora on the same side. None of previously undergone surgical intervention for this condition. Ophthalmological examination results were normal unaffected Dacryoscintigraphy performed bilaterally, specific regions interest identified. The scintigraphic images assessed quantitatively qualitatively by two nuclear medicine specialists. Evaluation between specialists conducted McNemar Bowker test Kappa test. Results: Eighty-one percent (34) female. mean age 68.23±9.67 years. In area exhibited edematous features. lacrimal pathway from punctum different methods. visual quantitative evaluation determine localization there a low moderate agreement observers (p=0.018, kappa value=0.252). evaluation, excellent (p=0.0001, value=1). Conclusion: is preferred as an imaging method due its non-invasive nature that does not disturb physiological processes. It offers advantages such lower radiation exposure higher patient compliance compared dacryocystography. However, it should be noted anatomical correlation dacryoscintigraphy relatively radiological By incorporating data into assessment dacryoscintigraphy, may possible enhance improve observer agreement, particularly presenting combination functional obstructions.
