BLOCKAGE AT THE LEVEL OF PUNCTUM OF LACRIMAL SAC.

BLOCKAGE AT THE LEVEL OF PUNCTUM OF LACRIMAL SAC.

CT DACRYOCYSTOGRAPHY

Clinical information:  Past h/o trauma. Watery discharge from left eye.

• CT DACRYOCYSTOGRAPHY was performed by topical instillation of CT contrast medium in both eyes.

• One drop was instilled in each eye every one minute for five minutes.

• This is a non-invasive procedure as compared to the conventional dacryocystography.

Findings:

• No evidence of passage of contrast material in left lacrimal sac.  

• Findings likely represent blockage at the level of punctum on left side.

• Contrast material passes through the right lacrimal canaliculi in the lacrimal sac and is seen to opacify the naso-lacrimal duct which appears to be patent.
