Renal tuberculosis (TB) is a rare clinical disorder in the pediatric population. A 15-year-old female presented with intermittent blurring of vision in both eyes associated with fever, abdominal pain, and weight loss. Fundus examination showed bilateral disc edema. Her blood pressure was 220/110 mmHg. Renal parameters were deranged with bilaterally enlarged kidneys. Renal biopsy was suggestive of epithelioid cell granuloma with Langhans type giant cells. The patient was diagnosed with as a case of refractory hypertension due to tubercular interstitial nephritis with bilateral Grade IV hypertensive retinopathy. She was started on antitubercular therapy and antihypertensives. There was a complete resolution of disc edema 2 months following initiation of therapy. Optic disc edema can be a presenting sign in renal TB. Early diagnosis and prompt referral can be associated with good visual and systemic outcomes.
