Purpose: To evaluate the efficacy of ivermectin and thiabendazole in confirmed cases of diffuse unilateral subacute neuroretinitis.
Methods: Two patients with diffuse unilateral subacute neuroretinitis were treated with anthelminthic drugs. The first patient was treated with ivermectin and the second, with thiabendazole.
Results: The worms were still mobile after treatment with ivermectin or thiabendazole. With the application of photocoagulation, the organisms were destroyed, and the patients' vision improved.
Conclusion: In these two patients, ivermectin and thiabendazole were not effective in treating confirmed diffuse unilateral subacute neuroretinitis.
