    Purpose: To study the impact of eyelid opening and closing on the volume and morphology of the lacrimal sac using computed tomography (CT) dacryocystography. Method: All of the patients underwent CT dacryocystography. After the contrast agents was injected into a patient's lacrimal sac, the orbit was first scanned with the eye open. And then the patient was told to close the eye firmly for a second scan of the orbit. The volume of the lacrimal sac was calculated by the image processing program which came with the CT machine. At the same time, the anteroposterior and transverse diameters of the lacrimal sac at 3 mm and 7 mm from the top of the lacrimal sac were measured. Results: 14 patients (14 eyes) who met the inclusion criteria were collected between December 2015 and January 2016. The average volume of .. Read More»
