Leber’s congenital amaurosis is a congenital retinal dystrophy that leads to severe vision loss at a very young age.
It is combined, almost always, with nystagmus, slow reflexes of the pupil of the eye and photophobia. The existence of hypermetropia and keratoconus is also possible. Visual acuity is very low from the very first months of life.
Visual acuity in this disease is less than 1/10 to 1/20. If the diagnosis is made when the child is about 3-4 years old, the remaining vision is possible, not just to maintain, but with the use of specially made and completely customized glasses and low vision aids to be noticeably improved and the child to be able to attend regular school.
