Ocular Hypertension Market Trends

Market Driver - Increasing Prevalence of Glaucoma due to Aging Population.

The global population is growing older at an unprecedented rate, with the population of those aged 65 years and over projected to nearly double from 2017 to 2050. As individuals get older, their risk of developing glaucoma steadily increases. Glaucoma is primarily an age-related disease, with its prevalence and severity strongly correlating with advancing age. Around half of those over age 80 have either glaucoma or show signs of damage from it. Growing numbers of the elderly globally will invariably lead to a higher burden of glaucoma cases in the coming decades.

Lifestyle factors associated with modern aging also tie into glaucoma risk. Greater life expectancy means more exposure to other health conditions linked to glaucoma, such as diabetes and hypertension. Prolonged use of corticosteroid medications often needed by seniors increases intraocular pressure (IOP) in the long-term. As people live longer retired lives, near work such as extensive computer or mobile device use becomes a longer-term hazard. Without regular eye checkups, age-related glaucoma can stealthily progress in older populations until substantial vision is lost.

Market Driver - Improved Formulations Spur Compliance Boosts Industry Developments.

Patient compliance with glaucoma medication has long been a challenge due to undesirable side effects of existing therapies. Eye discomfort from preservatives is a common complaint, while allergies and systemic side effects also reduce tolerance. This has motivated pharmacological researchers to develop new treatment formulations addressing tolerability issues. A key advance has been the design of preservative-free eyedrops that eliminate the most bothersome symptoms. By removing preservatives like benzalkonium chloride, intraocular irritation is notably decreased.

Another improvement has transitioned multiple glaucoma drugs into once-daily dosing from previous multiple daily doses. Simplifying dosage regimens Boost compliance by reducing burden and inconvenience. Newer prostaglandin analogs and selective laser trabeculoplasty provide full 24-hour IOP control from a single evening drop, improving over earlier bids and tertiary regimens. Formulations now also control IOP for over a month with as little as a weekly or biweekly application. Such extended dosing intervals are life-changing for patients and caregivers.

Younger patients especially struggle with commitment to chronic treatment and may be less prone to side effects tolerance. Innovations like sustained-release drug delivery directly address these needs. Implantable devices now under evaluation could hypothetically supply medication internally for years without repeated self-administration. Though high-risk surgeries, such approaches hold promise if proven safe and effective long-term. Steady progress in mitigating side effects through novel formulations thus strengthen adherence to care, critical for managing a chronic disease like glaucoma.

Market Challenge - High Cost of Advanced Treatments and Surgeries.

One of the major challenges faced by the ocular hypertension market is the high cost associated with advanced treatments and surgeries. Ocular hypertension often progresses to glaucoma over time if left untreated. While drugs are generally the first line of treatment, some patients require invasive surgeries or laser procedures to manage their condition effectively and prevent vision loss. However, such specialized treatments and surgeries come at a significant cost which may not be affordable or accessible to all patients. For example, newer minimally invasive glaucoma surgeries (MIGS) that aim to lower eye pressure through stent implantation start from around USD 4,000 per eye. Traditionally, trabeculectomy surgeries have a high success rate but involve more extensive tissue dissection and a longer recovery time. The financial burden of costly surgeries and lack of insurance coverage acts as a barrier for many patients globally, especially those in developing nations, to receive necessary glaucoma care intervention in a timely manner to preserve sight. This financially induced treatment delay or non-compliance poses a serious public health challenge.

Market Opportunity: Development of New Classes of Drugs, Including ROCK Inhibitors.

The development of new classes of drugs presents a major opportunity in the ocular hypertension market space. One particular class of drugs gaining attention are Rho kinase (ROCK) inhibitors. ROCK inhibitors work via a novel mechanism of action to reduce eye pressure by increasing the outflow of aqueous humor. Compared to prostaglandin analogs which are currently first-line drugs for glaucoma, ROCK inhibitors have shown potential to provide an added IOP reduction when used together in combination therapy. This enhanced IOP lowering effects may help more patients achieve and maintain their target pressure levels, thereby preventing further vision loss. Several ROCK inhibitor drugs are currently in late stages of clinical trials and if approved, are expected to capture significant market share in the coming years. Their advent signifies an important opportunity for drug manufacturers to offer novel treatment options that can be used alone or together with existing drugs classes. It also gives hope to patients, especially those who do not respond adequately to prostaglandins alone.
