A Rare Case of Cerulean Cataract in a Child with Cushing's Syndrome and Juvenile Idiopathic Arthritis

Background: Cerulean cataracts are uncommon congenital lens opacities that often manifest as bluish-white opacities in the lens throughout infancy. It is pretty uncommon for it to co-occur with both Cushing's disease and juvenile idiopathic arthritis (JIA), even though it may manifest alone. This instance emphasizes how important it is to diagnose and treat uncommon pediatric presentations using a multidisciplinary approach. Case Presentation: A 9-year-old child with Cushing's disease and previously diagnosed JIA presents with a complaint of progressive eyesight loss, arthralgias, and morning stiffness. His ophthalmologic evaluation revealed that he could only see light in each eye. A dense posterior subcapsular Cataract was observed by slit-lamp examination, with the characteristic cerulean Cataract presentation of tiny white opacities in concentric rings. Additionally, he developed oedema in his hands and legs. The patient's visual acuity fully recovered after having both cataracts removed. Conclusions: The significance of early and regular ophthalmologic screening in children with chronic systemic disorders is underscored by the peculiar correlation seen between cerulean cataracts, JIA, and Cushing's syndrome. It also shows that early surgery may be linked to acceptable visual outcomes, even in the face of perplexing clinical presentations.
