Sjogren - Larsson syndrome is a rare autosomal recessively inherited neurocutaneous disorder which occurs with 100% penetrance and is classically characterized by ichthyosis, spasticity and mental handicap. The disease is caused by mutations in the aldehyde dehydrogenase gene. The ocular manifestations are highly characteristic bilateral, glistening yellow-white retinal dots from the age of 1 to 2 years onward. The number of dots increases whit age. The extent of the macular abnormality does not correlate with the severity of the ichthyosis or with the severity of the neurological abnormalities. We report the clinical characteristics and ocular manifestations associated with the Sjögren-Larsson syndrome in two siblings, emphasizing the clinical importance of the ophthalmological examination of the Sjögren-Larsson syndrome. BPLS, a eleven year old boy and MPLS, a ten year old girl from non-consanguinous parents, presenting congenital ichthyosis, spastic diplegia and mental retardation. Miopia, fotofobia, subnormal visual acuity and glistening yellow-white crystalline deposits that were located in the foveal and parafoveal area were found in the ophthalmologic examination.
