The eye allergy treatment market size is expected to grow from US$ 3,924.88 million in 2024 to US$ 5,972.22 million by 2031; it is projected to register a CAGR of 6.3% during 2025-2031. The increasing eye allergy prevalence, surging geriatric population, and prescription to over-the-counter transition are noteworthy factors contributing to the expansion of the eye allergy treatment market size. Additionally, the sustained-release ocular implants and drug-eluting contact lenses are projected to bring new eye allergy treatment market trends in the near future.

Biologics and immunomodulators are used for treating severe conditions such as vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC). These therapies not only target but also eliminate the main causes of chronic inflammation, such as T-cell response dysregulation and cytokine overproduction, thus providing steroid-sparing options that carry lower risks of glaucoma and cataracts in the long run. This trend is being facilitated by the precision medicine approach, as shown in clinical trials where refractory cases had remission rates of up to 80%, while traditional topical treatments had rates of 50-60% only. Immunomodulators, such as topical cyclosporine A (Restasis) and tacrolimus (Protopic ophthalmic), are the drugs that inhibit the activity of calcineurin, thereby preventing the activation of T-cells and bringing down the number of eosinophils involved in the inflammation. A network meta-analysis conducted in 2024 involving 28 randomized trials rated tacrolimus as the top drug for VKC.

Biologics, which are monoclonal antibodies that target single pathways, are becoming the treatment of choice for the medical side of allergies with ocular manifestations. Dupilumab (Dupixent), an IL-4/IL-13 inhibitor, has been shown to improve the ocular scores in patients with AKC by 75% in phase 3 clinical trials, and at the same time, it has been relieving itch and light sensitivity in adults with co-existing atopic dermatitis. Omalizumab (Xolair), an anti-IgE agent, has been able to cut emergency visits by 55% in the population of patients suffering from acute allergic conjunctivitis. The new drug lirentelimab, an anti-Siglec-8 antibody, is also on the horizon, having achieved 90% pledged eosinophil infiltration reduction in VKC phase 2 data, thus earning its place as a frontline biologic in the future. As a result of the increasing cases of allergic eye disease worldwide, the aforementioned innovations not only promise to improve quality of life but also to reduce the frequency of flare-ups and to make long-term management safer for the most vulnerable patients, and are expected to emerge as a significant trend in the eye allergy treatment market.

Distribution Channel-Based Insights

Based on distribution channel, the eye allergy treatment market is segmented into the hospital pharmacies, online pharmacy, and drug stores. The hospital pharmacies segment held the largest eye allergy treatment market share in 2024. In the healthcare facilities, these outlets play an important role where ophthalmologists and allergists diagnose and treat conditions such as allergic conjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis with medicines. Medications like olopatadine hydrochloride (Pataday) and loteprednol etabonate (Lotemax) eye drops, for example, are often sold in these outlets, and they are not infrequently prescribed in-depth evaluations in hospital settings. There are several reasons leading to the development of this segment. The first one is that the rapidly increasing number of eye allergies, aggravated by environmental conditions, urbanization, and climate change, not only attracts more patients but also increases the demand for pharmaceutical services onsite since hospitals are becoming the patients' first choice for specialized care The growth of hospital pharmacies is a reflection of a combination of clinical reliability, policy support, and evolving patient needs, thus, they are recognized as a crucial channel for effective eye allergy management in a world that is increasingly becoming allergy-burdened, thereby fueling the eye allergy treatment market growth.
