Case Series: Glioblastoma Highlighting the Eye Care Provider's Role

Although the incidence of glioblastoma is relatively low, patients presenting with this malignant central nervous system tumor will typically experience visual symptoms. Eye care providers are uniquely positioned to assist with the diagnosis of glioblastoma and to manage its associated visual symptoms.

This case series will review the pathophysiology, diagnosis, treatment, and management of glioblastoma while highlighting the eye care provider's role over the course of the disease process.

Three patients with glioblastoma are presented: a 63-year-old White man with new onset of headache and blurred vision upon awakening, a 65-year-old White man with a weeklong history of peripheral vision deficit and neurological symptoms, and a 65-year-old White woman with visual field deficit and visual perception difficulties related to a known history of glioblastoma.

It is incumbent upon eye care providers to recognize examination findings such as new neurological symptoms and/or visual field defects that may warrant additional workup. In addition, eye care providers can serve a palliative role by maximizing the patient's remaining visual function and thereby quality of life.
