PURPOSE: To evaluate the efficacy of ivermectin and thiabendazole in c
onfirmed cases of diffuse unilateral subacute neuroretinitis. METHODS:
Two patients with diffuse unilateral subacute neuroretinitis were tre
ated with anthelminthic drugs. The first patient was treated with iver
mectin and the second, with thiabendazole. RESULTS: The worms were sti
ll mobile after treatment with ivermectin or thiabendazole. With the a
pplication of photocoagulation, the organisms were destroyed, and the
patients' vision improved. CONCLUSION: In these two patients, ivermect
in and thiabendazole were not effective in treating confirmed diffuse
unilateral subacute neuroretinitis.
