Dacryoliths causing intermittent epiphora associated with a patent lacrimal system.
We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fu...
متن کاملEvaluation of lacrimal drainage system by radionuclide dacryoscintigraphy in patients with epiphora
Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...
متن کاملEpiphora and the bony naso-lacrimal canal.
IT is possible to obtain a radiographic view of the naso-lacrimal canal "end-on" by directing a beam of x-rays down the axis of the canal to a film held horizontally in the mouth: the centre of the film is placed near the site of the first molar tooth (Brunetti, 1930; Kopylow, 1930; Toth, 1933), or the second pre-molar. Examples of such radiographs are shown in Figs 1, 2, and 3. The present inv...

متن کاملLacrimal scintigraphy. II. Its role in the diagnosis of epiphora.
Lacrimal scintigraphy (LS) was performed in 860 lacrimal drainage systems (LDS) in 188 patients with bilateral epiphora and 226 patients with unilateral epiphora. A very high incidence of canalicular obstruction was found in these patients, the incidence being higher in the group with unilateral epiphora. It is suggested that a canalicular block is a commoner cause of obstructive epiphora than ...
