Characterization of Retinal Microvascular and Choroidal Structural Changes in Parkinson Disease.

This study found that individuals with PD had decreased retinal VD and PFD as well as choroidal structural changes compared with age- and sex-matched control participants.

Choroidal Structural Analysis in Alzheimer Disease, Mild Cognitive Impairment, and Cognitively Healthy Controls.

TCA, LA, and CVI may differ between patients with AD, MCI, and healthy cognition, whereas SFCT may not differ among these groups. TCA, LA, and CVI deserve further study in subjects on the Alzheimer continuum.

Ultra-Widefield Imaging of the Retinal Macrovasculature in Parkinson Disease Versus Controls With Normal Cognition Using Alpha-Shapes Analysis.

This pilot study suggests that retinal vasculature assessment on UWF images using alpha-shape analysis reveals differences in retinal vascular network spread and complexity in PD and may be a more sensitive metric compared to fractal…
