Objective:
To describe the first patient with documented evidence of diffuse unilateral subacute neuroretinitis (DUSN) in both eyes.
Methods:
A 10-year-old healthy Brazilian girl was first seen with signs of late-stage DUSN in both eyes. A careful search for a nematode was performed in each eye.
Results:
A motile 550- to 660-microm nematode was found in the inferotemporal retina of the left eye. A similar-sized motile nematode was found in the superotemporal retina of the right eye. Both nematodes were treated with argon green laser applications with bilateral improvement of visual function.
Conclusion:
Although most patients with DUSN do not develop the disease in the fellow eye, this case demonstrates that DUSN can occasionally affect both eyes.
