Description
Summary:We report two cases of diffuse unilateral subacute neuroretinitis (DUSN) where multimodal imaging was used to assist in locating the nematode. The first case presented with clusters of migrating choroiditis with a suspicious tiny visualized worm noted on serial fundus photography. The second case had an atypical presentation with extensive exudative retinal detachment and a suspicious coiled worm in the subretinal space noted on optical coherence tomography. Both cases received oral albendazole for six weeks while the first case received additional argon laser photocoagulation to the suspected nematode. Both cases showed resolution of the ocular inflammation upon completion of treatment with no further recurrences. DUSN should be suspected in young and healthy patients with unexplained unilateral inflammatory eye disease with severe loss of vision. This series highlights the challenges faced in identifying the nematode in cases with suspected DUSN.
