Description
To investigate the GABAergic and glutamatergic systems and neural specificity in the visual cortex of glaucoma patients, the research team recruited 40 patients with glaucoma (14 with early glaucoma and 16 with advanced glaucoma) and 24 age-matched healthy subjects to undergo clinical ophthalmic exams and magnetic resonance imaging (MRI) with fixation tasks. Researchers obtained the following data:
  • Structural and functional images of the whole brain
  • Neurochemical profiles of the visual cortex
    • Measures of GABA concentration via MEshcher-GArwood- Point RESolved Spectroscopy (MEGA-PRESS)
    • Measures of glutamate concentration via Point RESolved Spectroscopy (PRESS)
  • Clinical ophthalmic measures:
    • Peripapillary retinal nerve fiber layer (pRNFL) thickness
    • Macular ganglion cell-inner plexiform layer (mGCIPL) thickness
    • Optic nerve head cup-to-disc (C/D) ratio
    • Neuroretinal rim (NRR) area from optical coherence tomography (OCT)
    • Visual field mean deviation (MD) from Humphrey standard automated perimetry
