Area of Science:

  • Neuroscience
  • Ophthalmology
  • Medical Imaging

Background:

  • Rhegmatogenous retinal detachment (RRD) is associated with visual pathway and gray matter changes.
  • White matter (WM) functional and structural alterations in RRD are not well understood.

Purpose of the Study:

  • To investigate white matter (WM) functional and structural integrity in RRD patients.
  • To identify potential neurobiological markers for RRD classification.

Main Methods:

  • Functional clustering networks and TractSeg for WM analysis.
  • Support Vector Machine (SVM) algorithms for patient classification.
  • Analysis of functional covariance connectivity (FCC) and WM amplitude.

Main Results:

  • RRD patients showed reduced FCC between Superior Temporal and Cerebellar Networks.
  • Increased WM amplitude observed in the Anterior Corpus Callosum Network.
  • Visual acuity negatively correlated with WM amplitudes in Occipital Networks.
  • SVM model using WM7_amplitude achieved high classification accuracy (AUC).

Conclusions:

  • WM functional and structural integrity are critically disrupted in RRD.
  • These disruptions are linked to cognitive and visual deficits.
  • WM amplitude analysis offers a promising biomarker for distinguishing RRD patients from healthy controls.
