| Popis: | PURPOSE: To evaluate the absorbed radiation dose to the lens of the eye, which is the critical organ in the primary beam during fluoroscopically guided transluminal balloon dilation of the lacrimal drainage system (balloon dacryocystoplasty) for obstructive epiphora and to evaluate the possibility of deterministic radiation effect on the lens. MATERIALS AND METHODS: The radiation dose to the lens of the eye during balloon dacryocystoplasty (which includes pre- and postintervention dacryocystography) was measured in 10 consecutive patients by using thermoluminescent dosimeters on the lids of both eyes as close as possible to the lenses. A C-arm angiographic unit coupled with a digital imaging system was used, with similar exposure and geometric parameters in all cases. RESULTS: The mean radiation dose to the lens of the treated eye was 4.6 mGy ± 2.2 (dose range, 1.9–9.1 mGy) and to that of the untreated eye was 38.5 mGy ± 17.5 (dose range, 14.7–67.8 mGy). CONCLUSION: The lens of the untreated eye receives ... |
