Glaucoma is the second leading cause of blindness worldwide and elevated intraocular pressure (IOP) is the most important risk factor. High IOP usually occurs as a result of an increase in aqueous humor outflow resistance at the trabecular meshwork (TM). An abnormal TM contributes to the development of glaucoma. Oxidative stress and vascular damage are considered two major cellular factors that lead to alterations in the TM. In this review, we discuss the findings related to oxidative damage to… 

Figures from this paper

Oxidative stress and antioxidants in the trabecular meshwork
TLDR
The mechanisms of oxidative stress in the TM and treatment strategies for this condition, including strategies involving antioxidants, noncoding RNAs and exogenous compounds, are discussed and new targets for glaucoma prevention are suggested.
Neuroinflammation in Primary Open-Angle Glaucoma
TLDR
The multiple cellular processes, which promote different risk factors in glaucoma including aging, oxidative stress, trabecular meshwork defects, glial activation response, neurodegenerative insults, and the altered regulation of immune response are summarized.
Prdx6 retards senescence and restores trabecular meshwork cell health by regulating reactive oxygen species
TLDR
Prdx6 is proposed as a potential therapeutic target to guard the TM from oxidative-stress and age-dependent accumulation of ROS by balancing redox-homeostasis to prevent ocular disorders, like glaucoma.
Physiological function of myocilin and its role in the pathogenesis of glaucoma in the trabecular meshwork (Review)
TLDR
The aim of the present review was to discuss the recent findings regarding the major physiological functions of myocilin, such as intra- and extracellular proteolytic processes, and the risk factors associated with myOCilin and the development of glaucoma.
Homocysteine induces oxidative stress to damage trabecular meshwork cells
TLDR
Patients with primary open-angle glaucoma and senile cataracts were demonstrated to have increased concentrations of Hcy in the plasma and aqueous humor, demonstrating that Hcy may be a potential treatment target in patients with POAG.
Strategies to Reduce Oxidative Stress in Glaucoma Patients
TLDR
It is proven that antioxidants and ω-3/ω-6 fatty acids at the molecular level in the glaucomatous anterior and posterior eye segments may help regulating the intraocular pressure as well as protecting the retinal neurons against OS/NS in POAG.
Interplay between Oxidative Stress, Inflammation, and Amyloidosis in the Anterior Segment of the Eye; Its Pathological Implications
TLDR
It is found that there is no consensus about which factor is the first to cause amyloidosis, and there is an interplay among these factors forming a vicious cycle that leads to the loss of protein structure in ocular pathologies, and multifactorial therapies should be developed to avoid protein misfolding and to stop the progression of ocular Pathologies.

Effects of oxidative stress in trabecular meshwork cells are reduced by prostaglandin analogues.
TLDR
Oxidative stress is able to induce characteristic glaucomatous TM changes in vitro, and these oxidative stress-induced TM changes can be minimized by the use of prostaglandin analogues.
The Dysfunction of the Trabecular Meshwork During Glaucoma Course
TLDR
Aqueous humour composition is characterised in glaucomatous patients by the presence of proteins deriving from apoptosis activation, mitochondrial damage, loss of intercellular connections, antioxidant decrease, which indicate that trabecular cell protection plays a role in the treatment and prevention ofglaucoma.
Sensitivity of ocular anterior chamber tissues to oxidative damage and its relevance to the pathogenesis of glaucoma.
TLDR
The peculiar sensitivity of the trabecular meshwork to oxidative stress is consistent with the damage selectively induced in it, triggering glaucoma's pathogenic cascade.
Oxidative Stress in Glaucoma: A Burden of Evidence
TLDR
Here the authors examine studies that attempt to provide evidence for and elucidate the role of oxidative stress in glaucoma and the potential role of ROS as part of the signaling process for cell death, analogous to that seen in neurotrophin-dependent neurons.
Sustained stress response after oxidative stress in trabecular meshwork cells
TLDR
Chronic oxidative stress in TM cells induced iROS production in mitochondria, which may contribute to the pathogenesis of the TM in glaucoma by inducing the expression of inflammatory mediators previously observed in glAUcoma donors as well as the levels of oxidative damage in the tissue.
Morphological changes in glaucomatous eyes and the role of TGFbeta2 for the pathogenesis of the disease.
Mitochondrial Damage in the Trabecular Meshwork Occurs Only in Primary Open-Angle Glaucoma and in Pseudoexfoliative Glaucoma
TLDR
The present study provides new information regarding basic physiopathology of this tissue: only in primary open-angle and pseudoexfoliative glaucomaas oxidative damage arising from mitochondrial failure play a role in the functional decay of trabecular meshwork.
Oxidative stress affects cytoskeletal structure and cell‐matrix interactions in cells from an ocular tissue: The trabecular meshwork
TLDR
It is concluded that under sublethal oxidative stress conditions, the TM cell adhesion to the ECM was impaired, and the short‐term loss of cell‐matrix adhesiveness may be related to the rearrangement of cytoskeletal structures.
