Researchers provide an in-depth analysis of retinal changes in early-stage Parkinson’s disease (PD) using optical coherence tomography (OCT). They highlight increased ganglion cell-inner plexiform layer thickness in the central macular region of PD patients and its association with disease progression. The findings suggest that early retinal alterations in PD patients may serve as valuable biomarkers for tracking disease progression.
