Bilateral Optic Neuropathy in Association with Diffuse Cutaneous Systemic Sclerosis with Interstitial Lung Disease.

To report a rare case of bilateral optic neuropathy in a patient with diffuse cutaneous systemic sclerosis with interstitial lung disease. Retrospective case report. A middle-aged female, who was a known case of systemic sclerosis with interstitial lung disease, was presented with sudden painless bilateral loss of vision for a month. The fundoscopy findings were suggestive of bilateral optic atrophy. Anti-topoisomerase I was found in the serum. Serum B12 and folate levels were reduced. HRCT Chest was suggestive of interstitial lung disease. MRI brain was normal and MRI orbit showed kinking of the left optic nerve. The findings were suggestive of diffuse cutaneous systemic sclerosis with interstitial lung disease and bilateral optic neuropathy. This is a rare case of bilateral optic neuropathy in a patient with diffuse cutaneous systemic sclerosis and interstitial lung disease with profound vision loss, in the absence of renal or cardiac involvement.
