This case report aims to highlight the role of Electroretinography ERG and Optical Coherence Tomography OCT in diagnosis and predicting treatment response in the clinical scenario of unexplained vision loss in a patient. The term paraneoplastic retinopathy PR was coined by Klingele and colleagues to describe autoimmune retinopathy associated with a distant neoplasm.

It is difficult to recognize but prompt diagnosis is crucial for the patient as retinopathy may be a herald sign that precedes systemic manifestations by months thus allowing early treatment of the underlying malignancy. The disease is an autoimmune condition characterized by vision loss blind spots and visual field abnormalities. These immunoglobulins bound an antigen from normal pooled retina having a molecular weight of 23000 daltons which we describe as the CAR antigen.

Cancer-related retinopathy a progressive autoimmune retinopathy is a disease of the retina the layer of tissue at the back of the eye that detects light and sends images to your brain. Antiretina antibodies have been found in the serum samples of four patients with cancer experiencing concomitant loss of vision cancer-associated retinopathy CAR syndrome.

CAR syndrome Paraneoplastic retinopathy. The retinal degradation is thought to be due to an immunologically mediated retinal degeneration caused by the cancer cells. Subacute visual loss and visual field constriction are the usual presenting symptoms.
