Can Eye Tests Detect Brain Tumors?

Could a simple eye exam uncover something far more serious than nearsightedness? The surprising answer is yes. Routine eye tests can sometimes detect brain tumors, even before other symptoms manifest. This underscores the importance of regular eye checkups as a vital part of overall health maintenance. The connection between eye health and brain tumors might seem unlikely, yet the intricate link between the optic nerve and the brain provides a crucial window into potential neurological issues. Tumors, particularly those located near the optic nerve or those causing increased intracranial pressure, can leave tell-tale signs detectable during a comprehensive eye exam. These signs can include swelling of the optic nerve (papilledema), changes in peripheral vision, double vision, or alterations in pupil size. While these symptoms can also indicate other conditions, their presence warrants further investigation to rule out a brain tumor.
