Brain networks reorganization and functional disability in glaucoma

Area of Science:

• Ophthalmology
• Neuroscience
• Medical Imaging

Background:

• Glaucoma is an optic neuropathy causing retinal ganglion cell loss and optic nerve damage.
• Emerging evidence indicates glaucomatous damage extends beyond the eye to the brain.
• This central nervous system involvement affects non-visual pathways and brain network organization.

Purpose of the Study:

• To summarize current knowledge on central brain circuit involvement in glaucoma.
• To explore the relationship between central nervous system changes and glaucoma-induced disability.
• To highlight the role of brain pathways in functional limitations associated with glaucoma.

Main Methods:

• Review of recent studies utilizing advanced neuroimaging techniques.
• Analysis of research on brain network organization in glaucoma patients.
• Synthesis of findings on central nervous system alterations in glaucoma.

Main Results:

• Glaucomatous damage affects brain regions beyond the primary visual pathways.
• Disruption of brain network organization is observed in glaucoma.
• Central nervous system changes are implicated in functional and daily living disability.

Conclusions:

• Glaucoma's impact extends to the central nervous system, affecting brain circuits.
• Central neural pathways play a crucial role in glaucoma-related disability.
• Understanding brain involvement is key to addressing functional limitations in glaucoma.
