What part of the body is primarily affected by glaucoma?

Glaucoma primarily affects the eye, specifically the optic nerve, which is crucial for vision. This condition is characterized by increased intraocular pressure that can damage the optic nerve over time. The pressure buildup may result from impaired drainage of the aqueous humor, the fluid in the eye. If left untreated, glaucoma can lead to vision loss and blindness. It is important to monitor eye health regularly, especially for individuals at higher risk due to factors such as age or family history. Understanding the impact of glaucoma on the eye highlights the importance of early detection and management to prevent serious vision complications.
