Leber's miliary aneurysms associated with telangiectasia of the nasal mucosa

Adult-onset Coats' disease

Coats disease is an idiopathic retinal vasculopathy characterized by telangiectasia and aneurysm of retinal vessels along with intra and subretinal exudation and fluid. While Coats disease is classically described in young male population, there is an adult variant of Coats disease presenting in adulthood. Adult onset Coats disease have a similar presentation but a slower progression, localised lipid deposition, both peripheral and juxta-macular involvement. In this review article, we have attempted to describe in detail the characteristic clinical features, pathogenesis, investigation modalities and treatment in adult-onset Coats disease.
