“…Further progression of tracer in the lacrimal system after medical treatment with oral pseudoephedrine in one patient was reported by Kim et al [6]. As shown by Palaniswamy et al external ocular massage can result in further progression of tracer [7]. To the extent of our knowledge, after washing method as an additional dynamic phase has not been reported in literatures.…”

“…Although dacryoscintigraphy plays an important role in diagnosis and management of patients, it is also valuable for evaluation of lacrimal system after surgical interventions as shown by Palaniswamy and Subramanyam [7]. Moreover, evaluation of stenosis in the lacrimal drainage system is a possibility that has been provided by nuclear scintigraphy [11].…”

“…Over the past years, many researchers showed improvement of the sensitivity and specificity of dacryoscintigraphy using various methods [5][6][7]. The aim of this study was to evaluate the efficacy of "after washing" imaging as an additional phase of imaging in diagnosis of lacrimal apparatus obstructions.…”

“…Although the application of a pinhole collimator camera during DSG [38] can be beneficial, it could be difficult to map the region of the eye with it because of the design of the collimator, since patients cannot fix their heads and not move. In our department, DSG using a pinhole collimator could have been performed only with patients in a lying position.…”

PurposeEpiphora is commonly caused by a relative or complete occlusion in the lacrimal drainage system (LDS), principally a nasolacrimal duct obstruction (NLDO). Dacryoscintigraphy (DSG), an extensively assessed imaging technique in diagnosing its abnormalities, can provide only planar images, according to which it needs to be improved. Our aim was to evaluate clinical utility of simultaneous DSG and single-photon emission computed tomography/computed tomography (SPECT/CT) combined with computed tomographic dacryocystography (CT-DCG) in the evaluation of LDS.MethodsDynamic imaging with DSG was performed, and tracer radioactivity was detected by a gamma camera. Successively, SPECT/CT images of the involved region were gained, followed by CT-DCG, during which a contrast medium was syringed into the affected LDS, and finally contrast CT scans were obtained again from the same region.ResultsFifty-seven patients, mean age 54.25 (± 18.26) years all with unilateral NLDO and 32 control subjects, all with patent LDS, mean age 49.88 (± 18.61) years were evaluated in the study. Delayed outflow of tearing eyes was exposed to DSG compared to the fellow and control eyes. The highest value for sensitivity was observed for SPECT/CT, followed by CT-DCG and DSG techniques, while combining DSG with SPECT/CT, DSG with CT-DCG, and SPECT/CT with CT-DCG, the sensitivity increased to 96.49%, 92.98%, and 94.73%, respectively.ConclusionsAlthough DSG is a sensitive nuclear medicine method, it only provides useful clinical data when simultaneously supplemented with SPECT/CT and CT-DCG trials as they jointly can offer valuable information about the localization of an abnormality and verify stenosis or obstruction.

Aim: We aimed to evaluate nasolacrimal drainage and accompanying additional occlusions after topical steroid treatment in punctal stenosis patients with recurrent epiphora. We evaluated the change in nasolacrimal drainage and the effect of the presence of additional pathology on the response to noninvasive medical treatment in the 6-month follow-up after treatment. Materials and Methods: Fifty-two patients with unilateral punctal stenosis and ipsilateral epiphora were included in our study. The mean age of the patients was 68.23±9.67. All patients received topical steroids for punctal stenosis. Dacryoscintigraphy was performed on all patients to evaluate additional pathologies before treatment. In the pre-treatment dacryoscintigraphy, there was obstruction at the lacrimal sac entrance in 7 (13%) patients, at the sac outlet in 24 patients (46%), and in the nasolacrimal duct in 21 patients (40%). Dacryoscintigraphy was repeated 6 months after treatment to evaluate the response to treatment. None of the patients had a history of surgery for the punctum or nasolacrimal system. Ophthalmological examination findings were normal on the non-complaining side. Dacryoscintigraphy on both sides was performed. Scintigraphic images were evaluated both quantitatively and qualitatively. Regions of interest were plotted on specific areas for quantitative evaluation. Results: Thirty-four (81%) patients were female. The punctal region had an edematous appearance in patients with punctal stenosis. Dacryoscintigraphy was repeated 6 months after the treatment to evaluate the response to the treatment. Nasolacrimal drainage was normal in 71% of patients who had stenosis at the entrance and exit of the sac as a result of punctal stenosis treatment. Epiphora and stenosis at the same level persisted in all 21 patients with nasolacrimal duct stenosis. Conclusion: Punctal stenosis is a common condition, especially in elderly patients. Methods with excellent patient compliance in diagnosis and treatment should be preferred first. Dacryoscintigraphy is a convenient method to identify patients for whom aggressive methods are required.
