What Could Cause Blurry Vision in Your Left Eye?
Some common causes of blurry vision to the left eye are abrasions to the cornea, infectious retinitis, age-related macular degeneration, stroke or trauma or injury to the eye, though there are a number of conditions that could cause blurry vision in only one eye. Diabetes patients may experience hazy vision with significant blood sugar level fluctuation. Other likely causes include cataracts, corneal opacification (or scarring), optic neuritis, migraine headaches and retinopathy.
Patients should seek medical attention if blurry vision comes on suddenly with symptoms such as a severe headache, loss of muscle control on one side of the body, difficulty speaking, facial drooping or vision loss. These symptoms indicate a stroke. Patients should also act immediately if blurry vision presents rapidly with severe pain in the eye. Slow onset hazy vision requires a visit to an eye care specialist.
In order to diagnose the cause of blurry vision, a doctor must assess the patient’s symptoms, examine the patient’s personal medical history and perform a physical eye examination. Diagnostic tests include a refraction exam, ophthalmoscopy exam, intraocular pressure assessment, an eye chart exam and slit-lamp examination. A patient may need blood tests to determine if there is an infection or bacteria causing blurry vision. The treatment depends upon the condition that causes the symptom.
