X-linked congenital stationary night blindness

X-linked congenital stationary night blindness is a disorder that affects the retina, the light-sensitive tissue at the back of the eye. People with this condition typically experience issues with their vision from birth. It is called 'stationary' because the vision problems usually do not worsen over time. The condition comes in two major types: the complete form and the incomplete form. In the complete form, all individuals experience night blindness, while not everyone with the incomplete form has this symptom. Other common visual problems include reduced sharpness (visual acuity), severe nearsightedness (myopia), nystagmus (uncontrolled eye movements), and strabismus (misalignment of the eyes). Importantly, color vision is generally not affected.

People with this condition often experience night blindness, which makes it hard to see in low light. They may also have reduced visual sharpness, severe nearsightedness, nystagmus, and strabismus. Color vision, however, is typically not affected.

X-linked congenital stationary night blindness is inherited in an X-linked manner, meaning the genes causing the condition are located on the X chromosome. The condition is divided into complete and incomplete forms, which are distinguished by their genetic causes. The specific genes responsible for the condition have not been detailed in the provided information.

Information about treatment is currently limited for this condition.

The vision problems associated with X-linked congenital stationary night blindness are typically stable over time. While people with this condition have difficulties with vision, the issues are usually not progressive. This means that although there may be challenges with night vision and other visual tasks, the condition does not usually worsen as time goes on.

Information about current research and future directions is currently limited for this condition.
