Cancer-associated retinopathy secondary to gallbladder carcinoma

Consider the diagnosis of CAR in patients with progressive concentric visual field loss, uveitis and fundus abnormalities, especially if bilateral. If CAR is suspected, perform a full work-up: FF-ERG, OCT, and whole-body PET-CT. In the treatment of CAR, immunosuppressives are mostly used, combined with antitumoral therapy. However, in the long-term, progressive visual loss is expected in most cases.
