Approach Considerations

No laboratory tests or imaging studies are indicated or necessary in patients with toxic exposure to Caladium, Dieffenbachia, or Philodendron. Direct visualization of the upper respiratory tract using endoscopy is indicated in patients with severe swelling, stridor, or respiratory compromise, although it rarely is necessary.

A complete ophthalmologic examination should be performed on patients who present with eye pain and redness. Fluorescein staining should be done to assess for corneal abrasions. Crystals may be visualized within the corneal stroma using a slit lamp.
