Central Retinal Vein Occlusion Revealing Coeliac Disease

INTRODUCTION: Thrombosis has been widely reported in coeliac disease (CD) but central retinal vein occlusion (CRVO) is rarely described. CASE PRESENTATION: A 27-year-old woman presented with acute visual loss and was diagnosed with CRVO. Her protein S and protein C levels were low and CD was diagnosed on the basis of endoscopic, immunological and histological results. A gluten-free diet resulted in favourable evolution. CONCLUSION: CD should be considered in young patients with thrombosis, especially if in an unusual location. Treatment is based on a gluten-free diet. LEARNING POINTS: Coeliac disease (CD) should be considered in young patients with central retinal vein occlusion (CRVO). Several mechanisms can cause thrombosis in CD. CRVO in CD is often reversible with a gluten-free diet.
