10 Glaucoma Symptoms
Reviewed: Dr. Gromatzky
Symptom #1: Decrease of Peripheral Vision
Peripheral vision is the part of vision that occurs out the sides of the eyes. Peripheral vision is important in recognizing well-known structures without needing to focus, identification of similar forms and movements, and delivery of sensations that form the background of detailed visual perception.
In glaucoma, the peripheral vision starts to decrease, and this is followed by a loss of central vision, which eventually results in blindness if left untreated. Peripheral vision is divided into far peripheral vision, mid peripheral vision, and near peripheral vision. When one loses peripheral vision and retains central vision, it results in tunnel vision.
