Diagnosing diffuse unilateral subacute neuroretinitis (DUSN) is challenging when the nematode is not visible under the retina. Specific clinical signs like sub-RPE tracts and RPE hypopigmentation aid in presumptive diagnosis.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Parasitology

Background:

  • Diffuse unilateral subacute neuroretinitis (DUSN) diagnosis is straightforward when the nematode is visible.
  • Diagnosis becomes presumptive and challenging when the nematode is located beneath the retinal pigment epithelium (RPE).

Observation:

  • A case report of presumed DUSN is presented to illustrate diagnostic challenges.
  • The nematode in this case was not located in the subretinal space, complicating diagnosis.

Findings:

  • Sub-RPE serpiginous tract in the infero-temporal retina.
  • Peripheral RPE hypopigmentation.
  • Positive clinical response to anti-helminthic treatment.

Implications:

  • A high index of suspicion is crucial for early DUSN diagnosis.
  • Prompt diagnosis and treatment can help control ocular inflammation.
  • Early intervention is key to preserving vision in DUSN cases.
