A 45-year-old woman presented with diminished vision in the left eye. Visual acuity was 6/9 and fundus showed a very large live nematode near the macula along with inflammatory outer retinal lesions in the periphery. We diagnosed the case as diffuse unilateral subacute neuroretinitis and treated with immediate focal photocoagulation of the worm along with oral antihelminthic drugs and corticosteroids. The report highlights the importance of prompt laser and steroids in achieving good structural as well as the functional outcome, and the added significance of advanced imaging techniques in prognosticating such patients.
