Macular dystrophy associated with Kjellin's syndrome: a case report

Hereditary spastic paraplegia (HSP) is characterized by weakness and spasticity of the lower extremities. Kjellin's syndrome is a rare syndrome associated with HSP. The syndrome is characterized by the presence of bilateral retinal flecks, similar to the findings in Stargardt disease and fundus flavimaculatus. We report the case of a 34-year-old male who presented with complete features of Kjellin's syndrome, with typical retinal findings observed on multimodal imaging (spectral domain optical coherence tomography [SD-OCT], near-infrared reflectance and autofluorescence imaging). The ophthalmological changes at early stages of the disease may not impair visual acuity. Therefore, the detection of central retinal degeneration requires thorough fundus examination.
