What causes sudden eyesight loss?
Sudden eyesight loss, also known as sudden vision loss, is a medical emergency and can be caused by a variety of underlying conditions. It is essential to seek immediate medical attention if you or someone you know experiences sudden vision loss. Some potential causes and considerations for sudden eyesight loss include:
Retinal Artery or Vein Occlusion: Blockage of blood vessels supplying the retina can lead to reduced blood flow and sudden vision loss. Retinal artery occlusion (often called "eye stroke") can result in sudden, painless vision loss, while retinal vein occlusion may cause blurry vision.
Ischemic Optic Neuropathy: Ischemic optic neuropathy occurs when there is a decrease in blood flow to the optic nerve, which can result in sudden vision loss, typically in one eye.
Macular Degeneration: Age-related macular degeneration (AMD) can lead to central vision loss, which may appear suddenly in some cases.
Retinal Detachment: A detached retina can cause sudden vision loss or the appearance of flashes and floaters. This is often accompanied by a perception of a curtain or shadow over part of the visual field.
Glaucoma: Acute angle-closure glaucoma can lead to a sudden increase in intraocular pressure, resulting in rapid vision impairment accompanied by eye pain and redness.
Diabetic Retinopathy: In individuals with diabetes, sudden vision loss can occur due to complications like diabetic macular edema or proliferative diabetic retinopathy.
Optic Neuritis: Inflammation of the optic nerve, known as optic neuritis, can cause sudden vision loss, usually accompanied by pain with eye movement.
Stroke: A stroke can affect the part of the brain responsible for vision, leading to sudden visual disturbances or loss.
Medications and Toxins: Certain medications or toxic substances can cause sudden vision changes as a side effect.
Trauma: Physical trauma to the eye or head can result in sudden vision loss or visual disturbances.
Infections: Severe eye infections, such as endophthalmitis, can cause rapid vision loss if not treated promptly.
Vascular Disorders: Conditions affecting blood vessels throughout the body, such as giant cell arteritis, can lead to sudden vision loss due to reduced blood flow to the eyes.
It's important to note that sudden vision loss is a medical emergency, and the underlying cause should be promptly diagnosed and treated by a healthcare professional, usually an ophthalmologist or an emergency room physician. Treatment options and outcomes depend on the specific cause of the vision loss and how quickly medical intervention occurs. Early diagnosis and treatment can improve the chances of preserving or restoring vision.
