A 42-year-old man presented with gradual painless progressive diminution of vision in both eyes of 3-month duration. Three months earlier to the onset of visual symptoms, he was diagnosed to have renal failure with systemic hypertension and hyperuricemia. He was started on allopurinol and oral steroids along with antihypertensive medication. While on treatment, he developed an allergic reaction to allopurinol, which resulted in Stevens-Johnson syndrome. At presentation, he was on oral steroids and antihypertensive drugs. On examination, there was no perception of light in the right eye and 20/160 in the left eye. Anterior segment examination of both the eyes was unremarkable, except for the presence of dry eyes. Fundus examination of both the eyes showed 1+ vitreous cells. The right eye had a pale disk with sclerosed vessels and confluent chorioretinal scars throughout the retina (Figure 1). The left eye revealed multiple patches of active and healed chorior-etinitis with few areas of vasculitis.
