Q

How do you evaluate for Dacryocystitis work up?

A
  • Compress lacrimal sac to get discharge (discharge = bacterial, fungal)
  • check EOM’s and for proptosis
  • gram stain if discharge
  • consider CT scan for cases that do not respond to treatment
  • NEVER DILATE/IRRIGATE during acute stage of infection
