What is the typical progression of visual field loss associated with glaucoma?

The typical progression of visual field loss associated with glaucoma starts with peripheral vision loss due to the damage to the optic nerve caused by increased intraocular pressure. This loss is often gradual and can progress to a "tunnel vision" effect, where central vision remains intact until late in the disease. This characteristic pattern of peripheral vision loss is crucial for early detection, as many patients may not notice changes in their vision until the condition has advanced significantly. Central vision loss occurs later in the disease course when the optic nerve damage is more severe, and complete vision loss is not typical unless the disease remains untreated for a long time. Sudden onset of vision loss is not commonly associated with glaucoma, as the condition usually develops over time. Thus, identifying the early signs of peripheral vision loss can help in the timely management of glaucoma.
