Lacrimal Scintigraphy and Dacryocystography in Patients with Epiphora

Lacrimal 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 ...

Comparison of dacryocystography and lacrimal scintigraphy in the diagnosis of functional nasolacrimal duct obstruction.

AIM It appears from the literature that no standardised examination exists for patients with functional nasolacrimal duct obstruction. The role of dacryocystography and lacrimal scintigraphy was compared in the diagnosis and management of these patients. METHOD Patients who were clinically diagnosed as having unilateral or bilateral functional nasolacrimal duct obstruction were prospectively ...

Digital subtraction dacryocystography and syringing in the management of epiphora.

AIM To compare the diagnostic information provided by digital subtraction dacryocystography (DCG) and syringing of the nasolacrimal system in patients with epiphora. METHODS Twenty-five lacrimal systems of 17 patients, who presented with unilateral or bilateral epiphora and no concurrent ocular or lid abnormality, were prospectively entered into the study. The patients initially underwent syr...

Evaluation 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...

Dacryocystography of normal and pathological lacrimal passages.
