Oxidative Stress: A Suitable Therapeutic Target for Optic Nerve Diseases?

Area of Science:

• Ophthalmology
• Neuroscience
• Cell Biology

Background:

• Optic nerve disorders involve retinal ganglion cell loss and optic nerve degeneration.
• Oxidative stress, an excess of reactive oxygen species (ROS), is a key factor in cell death pathways (apoptosis, autophagy, inflammation).

Purpose of the Study:

• To review the role of ROS in major optic neuropathies.
• To evaluate antioxidants as potential therapeutics for optic nerve diseases.

Main Methods:

• Literature review focusing on oxidative stress mechanisms.
• Analysis of preclinical data on antioxidant therapies.

Main Results:

• ROS contribute to pathogenesis in glaucoma, Leber's hereditary optic neuropathy (LHON), anterior ischemic optic neuropathy (AION), and optic neuritis (ON).
• Preclinical studies suggest antioxidants may mitigate oxidative stress damage.

Conclusions:

• Oxidative stress is a common pathway in diverse optic nerve disorders.
• Targeting ROS with antioxidants presents a promising therapeutic strategy for optic neuropathies.
