Mechanism of Action Ozempic ® reduces blood glucose through a mechanism where it stimulates insulin secretion and lowers glucagon secretion, both in a glucose-dependent manner. When blood glucose is high, insulin secretion is stimulated and glucagon secretion is inhibited.

Web. Controlling diabetes and maintaining the HbA1c level in the 6-7% range are the goals in the optimal management of diabetes and diabetic retinopathy. The exact mechanism by which diabetes causes retinopathy remains unclear, but several theories have been postulated to explain the typical course and history of the disease. [9, 10] See the image.

Web. Web. Diabetic retinopathy is caused by high blood sugar due to diabetes. Over time, having too much sugar in your blood can damage your retina — the part of your eye that detects light and sends signals to your brain through a nerve in the back of your eye (optic nerve). Diabetes damages blood vessels all over the body.

Hypertension is thought to contribute to the progression of diabetic retinopathy through two mechanisms. Firstly, the mechanical stretch and sheer stress imparted on endothelial cells by high blood pressure and increased perfusion of the retina, as well as higher viscosity of the blood, lead to endothelial dysfunction [ 71 ].

Diabetic Retinopathy Treatment. People with diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak. Or they can close, stopping blood from passing through. Sometimes abnormal new blood vessels grow on the retina. Web. Web. Web.

Inflammation, angiogenesis, oxidative stress, and apoptosis are major physiological mechanisms in the development of DR especially under hyperglycemia. Crosslinking of long-lived proteins may occur as a result of accelerated advanced glycation end product (AGE) accumulation in diabetes, resulting in stiffness and vascular dysfunction [ 101, 118 ]. Diabetic retinopathy, the most common complication of diabetes, is a neurodegenerative disease in the eye. And Parkinson's disease, affecting the health of 1-2% of people over 60 years old throughout the world, is the second largest neurodegenerative disease in the brain. As the understanding of diabetic retinopathy and Parkinson's disease deepens, the two diseases are found to show.

Research Article Total Bilirubin Predicts Severe Progression of Diabetic Retinopathy and the Possible Causal Mechanism Yu Ding , Junmin Zhao, Gangsheng Liu, Yinglong Li, Jiang Jiang, Yun Meng. Diabetic retinopathy (DR) is one of the largest causes of vision loss worldwide and is the principal cause of impaired vision in patients between 25 and 74 years of age [ 1-3 ]. In the United States, it is estimated that at least 4.2 million adults have DR and 655,000 have vision-threatening DR [ 4 ].

Diabetes can cause homeostatic changes in the retina that affect these glial cells; thus, glial cells promote inflammation in the retina, which is a driving force for sustaining angiogenesis in PDR ( Rezzola et al., 2017 ). These cells can be divided into three major categories: two types of macroglia (Müller cells and astrocytes) and microglia. Web. Web.
