Abstract Aim To report a case of intraocular tuberculosis presenting as acute macular neuroretinopathy and central retinal vein occlusion. Case description A 29-year-old man presented to the retina clinic with complaints of sudden blurring of vision in the left eye of 3 days duration. His visual acuity was 6/6 and 6/18 in the right and left eye, respectively. Fundus examination of the left eye showed features of central retinal vein occlusion. OCT showed features of type 2 acute macular neuroretinopathy (AMN) as well. Over a period of 2 weeks, the patient developed choroidal granulomas with overlying retinal elevation and peripapillary choroidal neovascular membrane and retinal granuloma. Mantoux test and HRCT chest confirmed the diagnosis of pulmonary tuberculosis. Results The patient was treated with a course of antitubercular therapy, oral corticosteroids and a single dose of intravitreal anti-vascular endothelial growth factor (1.25 mg/0.05 ml Bevacizumab, Roche Pharma) injection. After 6 months of therapy with ATT and tapering course of oral steroids, there was a complete resolution of all clinical signs including the choroidal granuloma with an improvement in visual acuity to 6/6. Conclusion Acute macular neuroretinopathy can complicate intraocular TB. Tuberculosis should be kept as one of the differential diagnosis in patients with AMN. Prognosis is generally good in patients of ocular TB presenting with retinal vascular occlusions.
