Cancer Associated Retinopathy (CAR) also known as Carcinoma Associated Retinopathy is an immune-mediated disease affecting the retina of the eye. It is a paraneoplastic type autoimmune retinopathy associated with cancer that can cause blindness. It can be seen in association with various types of cancers.
Cancer-associated retinopathy is commonly linked with cancers such as lung cancer and breast cancer, which trigger an autoimmune response due to malignant cells. In these cases, the immune system produces antibodies targeting retinal proteins, leading to retinal degeneration and overall vision loss.
If the tumor is next to the optic nerve, growth can compress the nerve and cause gradual loss of vision and unilateral proptosis. [2] Dyschromatopsia may occur. [1] Growth can also cause compressive vascular problems like central retinal vein occlusion. Lastly, growth also causes the tumor to exceed its blood supply.
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
All squamous cell carcinoma lesions are thought to begin via the repeated, uncontrolled division of cancer stem cells of epithelial lineage or characteristics. Accumulation of these cancer cells causes a microscopic focus of abnormal cells that are, at least initially, locally confined within the specific tissue in which the progenitor cell resided.
Ionizing radiation causes DNA damage, and cancer can develop as a result, he explains. The bottom line. In May 2011, IARC classified radio-frequency electromagnetic fields (RF-EMF) ...
