Retinal Nerve Fiber Layer and Macular Thickness in Parkinson's Disease Patients

Abstract

OBJECTIVE : This study aimed to evaluate the retinal nerve fiber layer (RNFL) thickness and macular thickness in Parkinson's disease (PD) patients., METHODS : The present study is a comparative cross-sectional, hospital-based study. A total number of 64 PD patients and 64 controls were recruited. Candidates that fulfilled the criteria with normal ocular examinations were undergone optical coherent tomography (OCT) examinations of the right eye. RNFL and macular thickness were evaluated., RESULTS : There was a statistically significant reduction in RNFL thickness in average (adjusted mean 84.32 vs 95.93, p CONCLUSION : The mean of the average, superior, and inferior RNFL thickness was significantly lower in the PD group compared to the control. The mean of the average, central, outer superior, outer inferior, and outer nasal macular thickness was significantly lower in the PD group compared to the control. Copyright © 2021, Abd Hamid et al.
