The potential complication of untreated glaucoma is damage to the optic nerve. Glaucoma is often associated with elevated intraocular pressure, which can lead to progressive damage to the optic nerve fibers. This damage can result in irreversible vision loss if the condition is not properly managed. The optic nerve is crucial for transmitting visual information from the eye to the brain, and any deterioration can seriously impair vision. Regular eye examinations and appropriate treatment are essential to prevent this complication and preserve vision.

In contrast, increased vision clarity and improved circulation to the retina represent positive outcomes that are unattainable if glaucoma is left untreated, as the condition tends to compromise vision rather than enhance it. Additionally, decreased eye pressure is not a potential complication; rather, effective treatment for glaucoma aims to control and reduce eye pressure to prevent nerve damage.
