Positive findings in a case of dacryocystitis?
- complaints of watering from the eye (left/right)
- h/o discharge now and then
- on examination anterior segment is normal
- regurgitation test positive
How will you conform your diagnosis?
How will you do syringing?
- put 4% xylocaine drops in eye and wait for few seconds
- dilate punctum with punctum dilator
- take a lacrimal syrngine with saline mounted with lacrimal canula
- insert the lacrimal canula into punctum push the saline from the syrngine
- inference: if saline comes into nose and throat there is no block
- if regurgitates from the same punctum: same canaliculi is blocked
- if regurgitates from the opposite punctum: either common canaliculi or nasolacrimal duct is blocked
how will you differentiate common canaliculi and naso lacrimal duct block?
