Subclinical Changes in the Juvenile Crystalline Macular Dystrophy in Sjögren-Larsson Syndrome Detected by Optical Coherence Tomography

Patients with SLS show a childhood-onset crystalline macular dystrophy with cystoid foveal atrophy on OCT in most cases. The intraretinal deposition of lipid metabolites may lead to Müller cell degeneration with subsequent formation of cystoid spaces or atrophic changes within the fovea. Because this macular dystrophy is present in all examined patients with SLS, familiarity with this maculopathy seems important for the diagnosis of this rare systemic disease.
