Summary
Diffuse unilateral subacute neuroretinitis (DUSN) is caused by a subretinal worm. Laser treatment of identified worms is effective, but thorough examination is crucial to detect multiple worms for successful therapy.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Parasitology
Background:
- Diffuse unilateral subacute neuroretinitis (DUSN) is typically attributed to a single helminth in the subretinal space.
- Laser photocoagulation is the standard treatment for localized worms causing DUSN.
Observation:
- A case of a 15-year-old male with longstanding DUSN is presented.
- Fundus examination revealed two worms, and focal laser photocoagulation was administered as treatment.
Findings:
- Post-treatment, no inflammation was observed.
- The patient showed sustained improvement over a 4-year follow-up period, with no disease progression.
Implications:
- Focal laser treatment is recommended for identified worms in DUSN, even in late disease stages.
- Comprehensive ocular examination is vital to identify and treat all causative worms, preventing therapeutic failure.
