Popis: Purpose To describe ophthalmological characteristics in children with Leigh syndrome (LS), an inherited, progressive, mitochondrial encephalomyopathy, at diagnosis and over time, and relate the results to causative genetic mutations. Methods Forty-four children with LS (19 females), with a median age of 2.4 years (range: 0.6–14.2 years) at diagnosis, were studied at the Queen Silvia Children's Hospital, Gothenburg, Sweden. Twenty-eight children had known genetic defects. The children underwent an ophthalmological examination, including visual acuity (VA), eye motility, refraction, slit lamp examination, ophthalmoscopy and a full-field electroretinogram (ff-ERG). Seventeen children were available for follow-up over a mean time of 5.4 years (range: 0.3–14.8 years). The results of these children were compared with an age- and sex-matched reference group of healthy children (n = 119). Results Altogether 36/44 of the children (82%) had ophthalmological abnormalities. The most common findings were refractive errors (n = 16/25), low VA (n = 9/36), strabismus (n = 8/42), reduced eye motility (n = 8/40), optic atrophy (n = 7/41), retinal pigmentation (n = 6/40) and nystagmus (n = 6/42). Several ophthalmological manifestations appeared over time. In 5/22 children, ff-ERG showed retinal dystrophy. No significant correlation between phenotype and genotype was found. The children with LS had significantly lower VA (p
