Open-Angle Glaucoma (OAG) Market Outlook
Thelansis’s “Open-Angle Glaucoma (OAG) Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2025 To 2035” covers disease overview, epidemiology, drug utilization, prescription share analysis, competitive landscape, clinical practice, regulatory landscape, patient share, market uptake, market forecast, and key market insights under the potential Open-Angle Glaucoma treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).
Open-Angle Glaucoma (OAG) Overview
Open-angle glaucoma is a progressive optic neuropathy characterized by the acquired loss of retinal ganglion cells and atrophy of the optic nerve. It constitutes over 90 percent of glaucoma cases in the United States. Elevated intraocular pressure stands as a major modifiable risk factor, though it is not a diagnostic criterion. Patients with elevated intraocular pressure have an approximately 1 percent per year risk of developing glaucomatous optic nerve damage. The pathophysiology involves a progressive reduction in the number of retinal ganglion cells, resulting from the pinching and death of nerve fibers at the point where the optic nerve exits the eye. This process leads to thinning of the neural rim and progressive enlargement of the optic nerve cup, causing a permanently decreased visual field. Key risk factors for open-angle glaucoma include elevated intraocular pressure, advanced age, family history, and African or Hispanic ancestry, as well as secondary insults to the eye such as uveitis, trauma, and steroid therapy. Although steroid therapy may contribute to elevated intraocular pressure, topical eye and periocular steroids are most likely to increase pressure.
