Emerging roles of the immune microenvironment in glaucoma

Area of Science:

• Ophthalmology
• Immunology
• Neuroscience

Background:

• Glaucoma is a leading cause of irreversible blindness.
• Pathology involves optic nerve degeneration, often linked to elevated intraocular pressure (IOP).
• Emerging evidence highlights the role of the immune microenvironment in glaucoma pathogenesis.

Purpose of the Study:

• To review recent advances in understanding the immune microenvironment in glaucoma.
• To explore the role of immune cells and neuroinflammation in disease progression.
• To discuss immune-based therapeutic strategies for glaucoma.

Main Methods:

• Literature review of studies on glaucoma and the immune system.
• Analysis of immune cell involvement (macrophages, microglia, T cells) in optic nerve damage.
• Examination of immune regulatory networks and their impact on IOP.

Main Results:

• Immune cell activation and infiltration contribute to retinal ganglion cell (RGC) damage.
• Neuroinflammation, driven by cytokines and chemokines, exacerbates RGC apoptosis.
• Immune dysregulation affects aqueous humour outflow, potentially increasing IOP.

Conclusions:

• The immune microenvironment is a critical factor in glaucoma pathogenesis.
• Targeting immune pathways presents novel therapeutic opportunities.
• Further research into immune modulation could lead to effective glaucoma treatments.
