Retinal Biomarkers in MPTP-Treated Monkeys for Parkinson's Disease Research

Data from a study on four non-human primates before and after MPTP-induced parkinsonism, plus four control subjects. It contains in vivo electroretinography and pupillometry measurements, alongside post-mortem retinal analyses, to identify potential early biomarkers for Parkinson's disease. The dataset includes functional and cellular data linking dopamine neuron degeneration to retinal changes.

Use Cases

• Identifying early retinal biomarkers for Parkinson's disease based on electroretinography waveform changes.
• Analyzing pupillary light response alterations in a parkinsonian model using pupillometry time-series data.
• Correlating in vivo functional measurements with post-mortem histological findings like retinal layer thickness.
• Testing the effects of L-dopa treatment on restored oscillatory potential amplitudes in the retina.

Strengths

• Includes longitudinal data from the same four subjects before and after MPTP administration.
• Combines multiple data modalities: in vivo functional tests (ERG, pupillometry) and post-mortem histological analysis.
• Dataset is openly available under a CC-BY-4.0 license, facilitating reuse.

Limitations

• The specific column names and data structure are not provided, limiting immediate usability.
• The dataset is relatively small, derived from a study involving eight non-human primates total.
• The 'Last updated' date of 2026-03-19 is a future date, indicating a potential metadata error.
