Abstract
Coats’ white ring can be a common finding in the cornea following incomplete removal of the iron rust ring after ocular trauma with iron particles. Though the finding is common and innocuous, it’s etiology is rarely understood and commonly considered as a corneal opacity following an ocular injury and less recognised as a distinct entity. It can be diagnosed from the history and the typical appearance as a ring of discrete white dots in the subepithelial layers with intact epithelium. Patients are asymptomatic and treatment is not required.
