Emerging strategies targeting genes and cells in glaucoma

Area of Science:

• Ophthalmology
• Genetics
• Cell Biology

Background:

• Glaucoma is a group of eye diseases causing progressive vision loss.
• Its complex etiology involves genetic and non-genetic risk factors, varying by population.
• Early diagnosis is challenging, but cellular dysfunction precedes retinal ganglion cell (RGC) death.

Purpose of the Study:

• To review recent findings on genes, molecules, and cell types in glaucoma.
• To highlight advancements in understanding glaucoma pathophysiology and treatment.
• To emphasize the role of cellular signaling and genetic dysregulation.

Main Methods:

• Review of current literature on glaucoma genetics and pathophysiology.
• Analysis of findings from large-scale genetic screening and animal models.
• Focus on cell type-specific vulnerabilities in RGCs.

Main Results:

• Identified numerous genes and molecular pathways implicated in glaucoma.
• Highlighted the importance of cellular signaling, gene dysregulation, and homeostatic imbalance.
• Demonstrated cell type-dependent vulnerability among RGCs contributing to specific visual deficits.

Conclusions:

• Lowering intraocular pressure (IOP) is primary but insufficient for glaucoma management.
• Genetic screening and animal models are crucial for identifying glaucoma mechanisms.
• Targeted cellular assessments in animal models aid in developing vision rescue interventions.
