Sudden loss of vision can indicate onset of stroke

Health News

New Delhi,
14th October 2019. A person experiences a mini stroke also known as
Transient Ischemic stroke, before suffering from a stroke. The symptoms and the
underlying causes are same in both cases. The patient experiences loss of
vision in one eye after TIA, where the eye loses vision and gradually can
gradually lead to complete loss of vision.

Vision loss
happens because the blood vessel supplying oxygenated blood from the eyes and
brain gets blocked. A blockage in the vessel can initially
manifest as transient or complete vision loss. Due to insufficient oxygen and
nutrients supplied to the affected part of the brain during stroke, the tissues
get damaged. In medical terms, it is also known as anterior ischemic optic
neuropathy or an eye stroke, which is a condition in which the blood flow
disrupts in the front part of the optic nerve said Dr. Jaideep Bansal, HOD –
Consultant, Neurology, saroj super speciality hospital new delhi delhi.

Any loss of vision in the left side of the visual field of each eye is an indication of stroke or lesion on the right side of the brain. Stroke has many other signs and symptoms depending on the functional area of the brain being affected. Most of the abilities including the eyesight also are functional by the right side of the brain, and any hindrance in the blood flow to the nerves joining the eyes and this part of the brain can indicate stroke.

Most of these patients can be handled by medicines, as the body helps to repair the arteries. According to Dr. Jaideep Bansal, if stroke is untreated, the average patient loses 1.9 million neurons. Golden hour of stroke is first 6-hours, and urgent treatment is the key. Medications prevent the extension of the blood clot in the area, taken along with blood thinners.  With the advancement in technology and expertise, the brain blood vessels can be repaired now by minimal invasive neuro-intervention techniques.
