Guide To The Causes And Complications Of Pituitary Tumors

Vision Loss

Vision loss is a complication that usually occurs with tumors that do not produce hormones or cause a deficiency of hormones the pituitary gland is responsible for producing. The reason behind this is symptoms of these types of pituitary tumors develop when the tumor is relatively small in size, where visual difficulties tend to occur when the tumor has grown to a larger size. Vision loss occurs when a pituitary tumor causes the optic chiasm or optic nerve to become compressed. The optic nerves are located in the area right above the pituitary gland, which makes them vulnerable to damage from a growing tumor. An affected individual may experience blurry, dim, or dark vision in one of their eyes if one of their optic nerves are being affected by the pituitary tumor. When a pituitary tumor presses on the optic chiasm in a certain way, patients may experience a loss of vision to the peripheral areas in both of their eyes.
