Understanding Glaucoma Pathophysiology
Glaucoma is a complex eye disease that causes progressive damage to the optic nerve, resulting in vision loss. The most common subtype of glaucoma is primary open-angle glaucoma (POAG), which accounts for 70% of cases worldwide. To comprehend the pathophysiology of glaucoma, it is essential to examine the key factors involved in its development.
One of the crucial aspects of glaucoma pathophysiology is the dysfunction of the trabecular meshwork (TM), a tissue responsible for regulating the outflow of aqueous humor, the fluid in the eye. In glaucoma, fibrosis occurs in the TM, leading to increased resistance to aqueous humor drainage. The presence of elevated levels of transforming growth factor-beta 2 (TGF-β2) in the aqueous humor contributes to this fibrotic response, impairing drainage and causing elevated intraocular pressure (IOP).
Oxidative stress and mitochondrial dysfunction also play significant roles in glaucoma pathophysiology. Oxidative stress, caused by an imbalance between free radicals and antioxidants, leads to damage and death of TM cells. Mitochondrial dysfunction, marked by impaired energy production, further exacerbates TM cell death and contributes to the development of glaucoma.
Additionally, vascular dysregulation is an important factor in glaucoma. It results in reduced ocular blood flow, leading to oxidative damage. The impaired blood flow and subsequent oxidative damage contribute to the progression of glaucoma.
