Ring and flower in the eye – An incidental finding of Wilson disease in a case of diabetic retinopathy: A case report

Abstract

This is to report a rare case of Wilson disease (WD) with Kayser–Fleischer (KF) ring with sunflower cataract along with diabetic retinopathy. A 43-year-old male patient presented to the comprehensive clinic with a chief complaint of diminution of vision of both eyes since 8 months. On ocular examination, the cornea showed golden brown color pigment deposition in the Descemet membrane, indicative of KF ring, which is a pathognomonic feature of WD. There was brown plaque or spoke-like radial opacities on the anterior lens capsule in both eyes, which gives sunflower appearance, which is also a feature of WD. The posterior segment revealed diabetic retinopathy in both eyes. Serum ceruloplasmin was reduced, and the bilirubin level was mildly raised. Liver function test was mildly altered. Urine excretory copper levels were raised. Ultrasonography of the abdomen and pelvis revealed liver cirrhosis with portal hypertension, splenomegaly, gross ascites, and gall bladder calculi. This is a rare case of WD with KF ring with sunflower cataract with diabetic retinopathy in both eyes. Slit lamp examination is mandatory to diagnose it as WD in the presence of KF ring.
