RESUMO
INTRODUCTION: Spastic paraplegia (SPG) is a heterogenous group of neurodegenerative disorders, that may include ocular involvement. Here we report the clinical data of a patient with late-onset Kjellin syndrome, a peculiar form of hereditary SPG with macular dystrophy. MATERIALS AND METHODS: Clinical, functional and multimodal retinal imaging data were collected. Genetic testing was performed by Whole Exome Sequencing (WES). RESULTS: A 52-year-old female patient with SPG of unknown origin was referred for a progressive visual acuity loss. Multimodal fundus imaging revealed a peculiar macular dystrophy. Given the specific association of macular dystrophy and SPG, a Kjellin syndrome was suspected and genetic testing performed. WES revealed biallelic pathogenic variants in SPG11, co-segregating with disease in the family. CONCLUSION: Careful ophthalmological examination prompted the diagnosis and guided molecular testing. This case underlines the importance of a neuro-ophthalmologic assessment in patients with SPG.
