Diabetic macular oedema (DME) is a common and sight-threatening complication of
diabetic retinopathy that causes a visible build-up of fluid in the central retina (the macula), leading to retinal thickening and distortion of vision. This condition is primarily caused by poorly regulated blood sugar levels that damage the capillary walls in the retina, leading to increased vascular permeability and leakage. As the diabetic population increases globally, so does the prevalence of DME, which stands as a leading cause of
visual impairment and
legal blindness among working-age populations.
DME is characterized by the accumulation of fluid in the macula, a critical area of the retina responsible for sharp central vision. The underlying causes of DME are multifactorial:
•
Chronic hyperglycemia leads to biochemical and structural changes within the retinal capillaries, damaging the blood-retinal barrier and causing leakage of fluid and lipids into the extracellular space.
•
Inflammation plays a crucial role; pro-inflammatory cytokines such as
vascular endothelial growth factor (VEGF) are upregulated, further exacerbating vascular permeability and contributing to retinal oedema.
• Long-term diabetes results in microvascular complications including microaneurysms and capillary nonperfusion, which contribute to the development of DME.
These multifaceted pathologic processes underscore the complexity of DME and the necessity of employing multiple therapeutic strategies that target different aspects of the disease process.
Historically, laser photocoagulation was the gold standard for treating DME, stabilizing vision loss by decreasing fluid leakage in the retina. However, over the past decade, there has been a paradigm shift toward pharmacotherapy owing to the superior outcomes reported with intravitreal agents. In particular, anti-VEGF drugs have become the first-line treatment because they directly target the upregulated VEGF, offering both functional and anatomical benefits.
Other treatment modalities include intravitreal corticosteroids, which address the inflammatory component of DME, and surgical interventions for refractory cases. These treatment options are frequently used in combination or in sequence, depending on patient response and specific clinical indicators, making the treatment landscape dynamic and continuously evolving.
The diabetic macular oedema treatment market has witnessed the emergence of a robust pipeline of both well-established pharmaceutical companies and innovative biotech firms. These key players are active across multiple stages of development—from preclinical research to late-stage clinical trials and product launches—and play vital roles in shaping the competitive landscape.
