Inherited retinal diseases (IRDs) are caused by genetic mutations that affect the retina, the light-sensitive tissue at the back of your eye. These mutations can be passed down from parents to children.

There are many different IRDs, and the specific gene that is mutated will determine the type of IRD and its symptoms. Some IRDs affect the rods, which are responsible for night vision, while others affect the cones, which are responsible for color vision and central vision. IRDs can also affect both rods and cones.

IRDs can be present at birth (congenital) or develop later in life. Some IRDs are progressive, meaning that they will get worse over time, while others are stable. Unfortunately, there is no cure for IRDs, but there are treatments that can help to slow the progression of vision loss and improve quality of life.
