Blindness brought on by an intact anterior visual pathway but due to bilateral occipital lobe involvement is known as cortical blindness. Compared to partial blindness, it is less frequent. The posterior reversible encephalopathy disease has a well-documented history of reversible cortical visual blindness (PRES). The neurological condition PRES is characterised by reversible subcortical vasogenic brain oedema and sudden onset neurological symptoms. This illness can be reversed with prompt diagnosis and treatment. It frequently occurs in conjunction with disorders like eclampsia, cancer, kidney disease, hypertension, and hypertension. This case involves a male teenager who was infected with COVID and later developed PRES. The presence of Anton's blindness complicated PRES. Utilizing radiological investigation, an early diagnosis was obtained, and once therapy was started, all symptoms disappeared.
