Retinal OCT Measurements in Parkinson's Disease Patients with Visual Hallucinations

An exploratory cross-sectional study of 30 patients with Parkinson's disease who underwent optical coherence tomography imaging and clinical assessment. The dataset, authored by Halil Onder and last updated in May 2026, includes retinal measurements such as RNFL thickness and temporal optic disc thickness, analyzed for association with visual hallucinations. Group comparisons and ANCOVA adjusting for non-motor symptom severity were performed.

Use Cases

• Investigating the association between temporal optic disc thickness and visual hallucinations based on OCT measurements.
• Comparing retinal nerve fiber layer thickness between patient groups with and without hallucinations.
• Analyzing the relationship between optic disc structure and non-motor symptom severity in Parkinson's disease.
• Exploring potential structural insights into neuropsychiatric heterogeneity using OCT data.

Strengths

• Includes OCT-derived retinal measurements for 30 Parkinson's disease patients.
• Clinical assessment includes structured interviews for identifying visual hallucinations.
• Analysis includes statistical adjustments for non-motor symptom severity using UPDRS-I.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 119.7 KB, indicating a limited preliminary analysis.
