Night blindness (nyctalopia/retinitis pigmentosa) is an eye condition that arises from damage to the retinal tissue cells responsible for light perception. More than half of the cases are caused by hereditary genetic disorders passed down from parents. In other instances, the genetic mutation develops for the first time in the individual. Due to the hereditary nature of the disease, consanguineous marriages increase the risk. This health issue, which is more common in men than in women, can sometimes manifest in syndromic forms that affect other organs besides the eyes. The age of onset and the progression of the disease vary significantly from person to person. While some individuals lose their vision at a young age, others can maintain their sight throughout their lives. Generally, the disease's progression follows a similar course within a family. Having information about the patients' family history significantly facilitates predicting the potential course of the disease.
