Hi,

I'm a developer and I spend a lot of time in front of my computer screen. In the last few weeks (maybe 3 or 4) I've suffered bouts of temporary blindness. It usually comes around late in my afternoon and coincides with a massive headache and sever dizziness.

Some, history here...

My mother passed away about 7 months ago from Glioblastoma. It was very sudden - she went in for surgery and never made it out. So I'm worried. Her symptoms were similar and they went ignored for 4 years or so.

So, I'm wondering if these incidents where I literally can't see my hand in front of my face is enough for me to go see a doctor. Right now, I'm subscribing it to stress. But I really have no idea.

Thanks.

  • There are 3 common causes of temporary blindness:Carotid artery narrowing (called stenosis) or disease can reduce the blood flow to the eye. This is the most common cause of episodic blindness. You have 2 carotid arteries, one on each side of the neck. They bring blood from the heart to the eyes and brain. Smaller arteries branch off from the carotid arteries to bring blood to the eyes. Plaques can build up along the inside walls of the arteries and slow the flow of blood. These plaques can break off and block the blood flow to the eyes. Diabetes, smoking, high blood pressure, and high cholesterol can cause problems in your carotid arteries and lead to episodic blindnessSmall blood clots or plaques may break off from heart valves or the inner walls of the heart. Pieces of the clot or plaque may float to the arteries of the eye. This can block blood flow to the eye and cause temporary blindness.Migraine headaches can cause spasms and narrowing in arteries leading to the eye.

Thank you very much, that was an informed reply.
