Diffuse bilateral subacute neuroretinitis: first patient with documented nematodes in both eyes.

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.
