Possible Causes of Visual Blackout

Content: Vascular problems can hinder this flow. A mini-stroke can also affect vision. Other Possible Causes
Other causes of a vision blackout include: High blood pressure
Visual migraine (painful headache)
Optic neuropathy
Giant cell arteritis
Increased intracranial pressure (in the skull)
Ocular ischemia (not enough blood flow in eye from carotid artery)
So, if your vision darkens, you might be having low blood pressure issues, other vascular problems, a retinal detachment or other issues with the structure of the eyes. It is important to see a doctor if you start to feel like you might faint or if you have other issues that might indicate something as serious as a stroke, like paralysis, confusion or speech impairment. Possible Causes of Visual Blackout
Low Blood Pressure
Vascular Problems
Retinal Detachment
Blood is not flowing adequately to brain and eyes
High blood pressure, strokes and other vascular problems can interfere with blood flow to eyes and hinder vision
If the retina tears, fluid can build between retina and wall of eye and hinder vision

When there is a tear in the retina, fluid can build up between the retina and wall of the eye, causing loss of vision. Danielle Elder, Flickr. Some rights reserved.
