Mitochondrial insufficiencies and neuroprotection in glaucoma

Area of Science:

• Ophthalmology
• Neuroscience
• Cell Biology

Background:

• Glaucoma management traditionally focuses on intraocular pressure.
• Despite current treatments, many glaucoma patients experience disease progression and vision loss.

Purpose of the Study:

• To explain how mitochondrial biology derangements contribute to glaucoma pathophysiology.
• To explore novel therapeutic strategies targeting mitochondria for glaucoma.

Main Methods:

• Conducted comprehensive literature searches across multiple databases.
• Utilized keywords such as "glaucoma", "mitochondria", "oxidative stress", "metabolism", "inflammation", "transport", and "genetics".

Main Results:

• Mitochondrial insufficiencies are central to glaucoma pathophysiology, driving neuroinflammation, metabolic issues, and axonal transport disruption.
• Genetic factors contribute to mitochondrial dysfunction, leading to oxidative stress and retinal ganglion cell damage.
• Defects in mitochondrial biology across ocular cells exacerbate glaucoma progression.

Conclusions:

• Targeting mitochondrial insufficiencies offers a new therapeutic avenue beyond intraocular pressure management.
• This approach holds promise for preventing vision loss and potentially treating glaucoma effectively.
