Oxidative Stress and Its Regulation in Diabetic Retinopathy

Area of Science:

• Ophthalmology
• Endocrinology
• Cell Biology

Background:

• Diabetic retinopathy (DR) is a leading cause of vision loss in diabetic patients, linked to hyperglycemia.
• Hyperglycemia induces oxidative stress, damaging retinal tissues due to the retina's high metabolic rate.
• DR affects approximately 20% of the global diabetic population, encompassing maculopathy and proliferative stages.

Purpose of the Study:

• To review the role of oxidative stress in diabetic retinopathy pathogenesis.
• To elucidate the molecular mechanisms and retinal cell involvement in DR-associated oxidative stress.
• To discuss therapeutic strategies targeting oxidative stress in DR.

Main Methods:

• Literature review synthesizing current research on oxidative stress in diabetic retinopathy.
• Analysis of molecular pathways, including advanced glycation end-products and non-coding RNA.
• Examination of the impact of metabolic memory on oxidative stress in DR.

Main Results:

• Oxidative stress is a key pathological mechanism in diabetic retinopathy, affecting retinal cells.
• Advanced glycation end-products, metabolic memory, and non-coding RNA contribute to DR progression via oxidative stress.
• The retina's susceptibility to oxidative stress is exacerbated by hyperglycemia.

Conclusions:

• Oxidative stress plays a critical role in the development and progression of diabetic retinopathy.
• Understanding these mechanisms opens avenues for novel therapeutic interventions targeting oxidative stress.
• Targeting oxidative stress pathways offers potential for preventing or treating diabetic retinopathy.
