Vision loss from glaucoma typically begins in which area of vision?

In glaucoma, the initial stages of vision loss usually start with peripheral vision. This condition affects the optic nerve and leads to a gradual loss of this peripheral field, often without the patient immediately noticing it. As the disease progresses, it may lead to tunnel vision, where central vision remains intact for a longer period but peripheral vision continues to deteriorate. Patients may not recognize the loss until significant damage has occurred because central vision is responsible for tasks such as reading and driving.

This characteristic progression is essential in understanding the importance of regular eye examinations for early detection of glaucoma. Early intervention can help preserve vision by managing intraocular pressure, thereby slowing down or preventing further vision loss. The other areas of vision, such as central and long-distance vision, are not typically affected in the early stages, making peripheral vision loss a hallmark feature of glaucoma.
