Severe mucopurulent discharge is suggestive of:
- Keratoconjunctivitis sicca
- Bacterial keratoconjunctivitis
The cornea is remarkably clear, making KCS unlikely. Flushing of the nasolacrimal duct confirms a diagnosis of dacryocystitis. Treatment in these cases can be challenging and usually involves a combination of systemic and topical antibiotics as well as repeated flushing of the nasolacrimal duct with antibiotics (every 1-2 days for 10-20 treatments). Lack of response to therapy is an indication for radiographs (including contrast studies) to rule out neoplasia or fistulas.
