6. Visual problems
Benign brain tumors can cause various visual symptoms, including visual acuity issues or restricted visual field. It happens due to the tumor pressing on the brain’s nerves and other vital structures. Patients may find that their vision becomes blurred or they experience double vision. They may also experience a reduced field of vision or difficulty seeing in certain directions.
Due to the pressure of the tumor on the optic nerves, patients can lose a big portion of their visual field in some cases, making it difficult to perform activities of daily living. Additionally, those with benign brain tumors may suffer from eye pain, loss of peripheral vision, and difficulty focusing on objects in their visual field. Depending on the size and location of the tumor, some patients may experience vision loss immediately or over a short time.
