Can glioblastoma cause eye problems?
Ocular manifestations of gliomas and GBM are similar to those of common space-occupying lesions and may include any of the following: Blurred vision. Visual field loss (defects correlate with site of tumor: homonymous hemianopsias) Spatial neglect.
Can brain tumors cause eye problems?
Yes, they can. Although eye problems typically stem from conditions unrelated to brain tumors—such as astigmatism, cataracts, detached retina and age-related degeneration—they can sometimes be caused by tumors within the brain. Brain tumors can lead to vision problems such as: Blurred vision.
Can glioblastoma cause blindness?
Prognosis is extremely poor, with most patients becoming blind, and ultimately dying within 1 year.
Can glioblastoma be detected in eye exam?
