Leber's Congenital Amaurosis is a congenital retinal dystrophy that causes severe vision loss from birth. Because the retina is profoundly affected from infancy, most individuals have little to no light perception early on, which is described as severe or complete blindness. This early, profound impairment is the hallmark, even though some patients may have a little residual vision or light perception depending on the specific mutation.

Additional features that help identify this condition include nystagmus (involuntary eye movements) and an abnormal or absent pupillary light reflex, with electroretinography often showing very reduced or nondetectable responses. It’s important to distinguish this from hearing loss (which points to Usher syndrome in some cases) or from conditions that present with gradual tunnel vision over time. The typical description for Leber’s Congenital Amaurosis aligns with profound vision loss from infancy, i.e., what is commonly interpreted as blindness.
