<bold>Aim:</bold> To present a rare clinical case of X-linked retinoschisis, confirmed clinically, electrophysiologically and genetically.
<bold>Material and methods:</bold> A 12-year-old boy underwent detailed ophthalmic examination including fundus photography, full-field, multifocal and pattern electroretinography, visual field testing, optical coherence tomography, which established the clinical diagnosis, confirmed also genetically.
<bold>Results:</bold> The clinical findings included a slight loss of vision, central and paracentral scotomas, a characteristic spoke-wheel pattern appearance of the macula in fundoscopy and the pathognomic appearance of splitting of the retinal layers in the macula with foveal schisis with cystic spaces on OCT. Reduced cone and rod ERG responds were detected with the characteristic decreasing of b-ware near the isoelectric line. The genetic analysis found that the patient was hemizygous for the missense mutation c.598G>A (p.Arg200Cys) of RS1 gene, coming from his asymptomatic mother.
<bold>Conclusion:</bold> The comprehensive clinical, electrophysiological and genetic testing of patients with rare hereditary retinal dystrophies is essential for the correct diagnosis and the choice of therapeutic approach.
