[Clinical treatment of diffuse unilateral subacute neuroretinitis with albendazole].

PURPOSE: To describe the evolution of a series of cases of diffuse unilateral subacute neuroretinitis (DUSN) treated with albendazole.

METHODS

Interventional case series. The authors developed a non-randomized clinical trial protocol to investigate the clinical evolution of diffuse unilateral subacute neuroretinitis cases treated with albendazole. According to protocol criteria up to now, six patients were selected that will be described separately.

RESULTS

Of the six studied patients, four presented the worm. All six patients treated with the antiparasitic drug showed improvement of visual acuity and of chorioretinal scars. During the weeks of treatment, evidence of worm inactivation was documented for the four patients with visible worms. No adverse drug side effects were observed.

CONCLUSIONS

The antiparasitic drug albendazole seems to be beneficial and safe in patients with diffuse unilateral subacute neuroretinitis. More studies are necessary to evaluate the effectiveness of albendazole in the treatment of diffuse unilateral subacute neuroretinitis.
