Further Outpatient Care

The patients should be observed closely until the organism is identified for focal laser photocoagulation.

Patients should receive follow-up evaluations every 1-2 weeks until the inflammation resolves.



DUSN is a condition in which prompt identification and destruction of the infecting nematode can result in the cessation of symptoms and the preservation of good visual acuity. If untreated, the disease progressively damages the retina and the optic nerve, leading to severe visual loss.


Patient Education

If the vision is reduced substantially in one eye, then emphasis should be made regarding monocular precautions and the use of protective safety glasses.
