Proliferative Diabetic Retinopathy Market Trends

Market Driver - Growing Prevalence of Diabetes Leading to Increased Cases of Diabetic Retinopathy

Diabetes is a chronic medical condition that has impacted millions worldwide over the past few decades. Both types 1 and 2 diabetes damage small blood vessels in the retina, resulting in diabetic retinopathy. It is estimated that nearly all type 1 diabetics and over 60% of type 2 diabetics develop some form of retinopathy after 20 years of living with this metabolic disease.

As more individuals are diagnosed with diabetes each year due to changing lifestyles and inadequate physical activity levels, the at-risk patient pool for developing retinal complications continues to expand rapidly.

Nearly half a billion adults were living with diabetes globally in 2019 according to the latest WHO estimates. This number has doubled since 1980 and is further expected to rise in the coming years due to aging populations and the growing prevalence of obesity. Countries with developing economies in particular have witnessed massive surges in diabetes incidence rates due to growing westernization of diets and reduced physical exertion in daily lives.

All these newly diagnosed diabetes cases will fuel the demand for retinopathy screening and treatment in the long run as retinal damage occurs years after the onset of the metabolic disease and its inadequate management.

Market Driver - Technological Advancements in Diagnostic and Therapeutic Approaches

Significant technological advancement is another major driver bolstering the proliferative diabetic retinopathy market. Various new diagnostic imaging systems and therapeutic drugs/devices have improved ability to detect retinopathy at early stages and deliver more targeted treatment interventions.

Wide field digital imaging such as Optos and Heidelberg retina angiography have replaced conventional mydriatic cameras for non-mydriatic and ultra-wide field retinal screening. These provide advantages of greater field of view to detect peripheral lesions, higher resolution and easier portability. In terms of therapeutics, anti-VEGF injections through innovations like Ozurdex implant and port delivery systems have made vascular ablation procedures less invasive and more effective.

Advances in laser photocoagulation including pattern scanning laser (PASCAL), navigated laser and automated variable spot size also enable more precise photocoagulation with less collateral damage. Surgical technologies have also progressed, examples being small gauge vitrectomy systems and lens sparing vitrectomy. These allow faster surgery time, sutureless closure and early visual rehabilitation.

Researchers are additionally investigating drug therapies beyond anti-VEGFs and new coating technologies for controlled drug delivery through implants inserted in the eye. Such continuous developments in retinopathy imaging, screening and therapeutics are allowing earlier detection as well as personalized treatment approaches tailored for each patient's needs.

Market Challenge - High Costs Associated with Advanced Treatments

One of the major challenges faced by the proliferative diabetic retinopathy market is the high costs associated with advanced treatment options such as anti-VEGF injections and laser surgery. These treatment methods require specialized equipment, regular follow-up appointments and monitoring, and frequent re-administration of drugs in some cases. This makes the overall cost of treatment quite steep.

For example, a single intravitreal injection of anti-VEGF drugs like ranibizumab or aflibercept can cost thousands of dollars. Patients are often required to receive multiple injections periodically to manage their condition. Similarly, procedures like panretinal laser photocoagulation require specialized lasers and surgical facilities that contribute significantly to the overall costs.

The economic burden of frequent and expensive treatments poses challenges in terms of access and adherence to therapy, especially in developing countries and for the uninsured population in developed markets. This high cost of care is a major limiting factor for the overall growth of this market.

Market Opportunity - Growing Investment in R&D for Novel Therapeutics

One of the key opportunities for the proliferative diabetic retinopathy market is the growing levels of investment seen in R&D for novel therapeutic drugs and technologies. Several biopharmaceutical companies and venture capital funds are investing heavily in developing new drug delivery approaches, biomarkers, and molecular targets to treat proliferative DR.

For example, significant research is ongoing to develop sustained release intraocular implants that can continuously deliver anti-VEGF drugs over longer periods, reducing the frequency of injections. Other novel avenues being explored include gene therapy, stem cell therapy, and therapies targeting new molecules like connective tissue growth factor.

The success of these development efforts can help address some of the current limitations and introduce more efficacious and cost-effective treatment options. This growing pipeline of innovative therapies and the expected approval of novel drugs in the near future present lucrative growth prospects for stakeholders in the proliferative DR market.
