Popis: BACKGROUND Patients with Gaucher disease (GD) have an increased risk for parkinsonism. Retinal thinning has been described in parkinsonism as an early nonmotor feature. Scarce reports have addressed retinal thickness changes in GD. OBJECTIVES The objectives of this study were to compare ganglion cell complex (GCC) thickness in adolescents and young adults (AYAs) with GD with healthy control subjects, and to correlate it with the presence of parkinsonian features (PFs), clinical prodromal markers of parkinsonism, severity score index (SSI), and glucosylsphingosine (Lyso-GL-1). METHODS This study included 48 AYAs with GD (11-29 years), 11 with manifest PFs (Group 1) and 37 with no PFs (Group 2), and 48 matched healthy control subjects (Group 3). Age of GD onset, disease duration, medication history, history of constipation, SSI, and hematological assessment were done. Neurocognitive evaluation included Parts I, II, and III of the Unified Parkinson's Disease Rating Scale (UPDRS), Wechsler Adult and Intelligence Scale and Wechsler Intelligence Scale for Children, Beck Depression Inventory (BDI), rapid eye movement sleep behavior disorder (RBD) scale, Munich Parasomnia Screening scale, and the olfactory dysfunction scale. Molecular analyses of the acid GBA gene and Lyso-GL-1 were done. Participants underwent full ophthalmological examination and optical coherence tomography with GCC thickness measurement. RESULTS GCC was significantly thinner in Group 1 than in Groups 2 and 3 (P
