At what stage of life is open-angle glaucoma most commonly observed?

Open-angle glaucoma is most commonly observed in later life, particularly in individuals over the age of 40. This condition is characterized by a gradual increase in intraocular pressure, which can lead to optic nerve damage and vision loss over time. The prevalence of open-angle glaucoma increases with age due to various factors, such as the aging of the optic nerve and changes in the eye's aqueous humor drainage system.

While open-angle glaucoma can technically occur at any age, it is much rarer in childhood and young adulthood compared to middle age and later life. Thus, the correct identification of later life as the stage when open-angle glaucoma is most prevalent is supported by statistical data and clinical observations. Recognizing the age-related risk factors can assist in early detection and management of this chronic eye condition.
