Blurred vision in one eye can be caused by pressure buildup, cataracts, glaucoma, ocular migraines, and diabetic retinopathy. It can also be a symptom of a stroke and should always be evaluated by a doctor. Prompt attention can save eyesight.
Blurred vision in one eye is a serious medical symptom and should always be evaluated by a doctor. When the optic nerve is unable to process images as they are seen, it causes blurred vision. This is often caused by a build up of pressure within the eye or a clouding of the eye lens. Vision problems in one eye can be caused by ocular migraines or diabetes; any headache with blurred vision can be a symptom of a stroke, however, and the individual should be examined by a doctor immediately.
Cataracts are the most common cause of blurred vision among the elderly. The eye becomes foggy due to the breakdown of proteins that form the lens. Objects become blurry, and a halo may appear around lights. Some people report a decrease in color intensity and difficulty seeing even at night.
Glaucoma is an eye disease caused by a buildup of pressure within the eye and can cause blurry vision. The pressure damages the eye nerve, causing vision changes. Medical professionals usually recommend a series of eye drops to reduce the amount of fluid in the eye and reduce pressure. Sometimes, a laser treatment can be done to release the fluid by creating new outflow channels.
Headaches accompanied by vision changes are not unusual. Migraine sufferers often report auras or floaters in their visual fields before a migraine attack. Blurred vision in one eye can occur as part of a migraine phenomenon called ocular migraine. The primary symptom of this condition is changes in the vision in one eye that last for a few hours, but typically there is no headache.
Diabetics are particularly at risk of vision problems due to uncontrolled blood sugar levels. Diabetic retinopathy can start with blurred vision and fluctuating visual fields. Additional fragile blood vessels can grow into the retina, distorting the images processed by the optic nerve. A buildup of scar tissue from the rupture of these small blood vessels can cause retinal detachment, which can lead to blindness. Diabetic retinopathy is often treated with laser surgery in an outpatient setting; recognizing the symptoms early can save the eyesight of those affected by this disease.
Vision changes with a sudden headache can be a sign of a stroke. If blurry vision occurs at the same time as muscle weakness, tingling in the extremities, dizziness, or sudden inability to articulate, prompt attention from medical personnel is imperative. Blurred vision in one eye is always a matter that requires medical attention, as it could be a sign of a serious illness.
