Cím:Evaluation of the tear clearance rate by dacryoscintigraphy in patients with obstructive meibomian gland dysfunction / Sandor Barna, Ildiko Garai, Rudolf Gesztelyi, Adam Kemeny-Beke

Megjegyzések:Purpose: To measure tear clearance values in patients with meibomian gland dysfunction (MGD) with a dynamic nuclear medicine method, namely, dacryoscintigraphy (DSCI). Methods: Twenty-four MGD patients and 24 healthy volunteers were examined. During DSCI one drop of a solution with 100 MBq/mL99mTc sodium pertechnetate was instilled with a micropipette into the lacrimal lake of both eyes. Measurements were performed according to a dynamic data acquisition protocol, which resulted in summed DSCI images. Data were also evaluated separately in special regions of interest (ROI), and consecutive time activity curves were created. Tear clearance (T?) values were calculated based on the activity curves. In addition, tear osmolarity measurements, tear breakup time (tBUT), and Schirmer I (STI) tests were performed prior to DSCI examination. Results: The T? values were 29.91 ? 11.61 min in MGD patients and 6.26 ? 1.5 min in healthy controls. Tear osmolarity parameters were 308 ? 9.41 mOsm/L and 288.9 ? 6.4 mOsm/L, tBUT values were 5.54 ? 2.73 s and 11.4 ? 2.7 s, while the STI test values were 6.17 ? 2.78mm and 13.58 ? 3.8 mm, respectively. The differences were significant (p < 0.01) in all cases. Conclusions: Although the MGD patients' lacrimal drainage systems were patent their tear clearance values were significantly higher than those of healthy volunteers, which may be caused by decreased drainage of tears from the eyes towards the nasal cavity. The understanding of new features regarding the altered physico-chemical characteristics of MGD tears has been augmented by the results of this study.

Cím:Clinical utility of SPECT/CT and CT-dacryocystography-enhanced dacryoscintigraphy in the imaging of lacrimal drainage system obstruction / Sandor Barna, Ildiko Garai, Kornel Kukuts, Rudolf Gesztelyi, Laszlo Toth, Adam Kemeny-Beke

Megjegyzések:Purpose Epiphora 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. Methods Dynamic 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. Results Fifty-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. Conclusions Although 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.
