Blurred vision in one eye accompanied by a headache may seem like a minor inconvenience, but experts warn it could be a sign of serious medical conditions that require urgent attention.
What Could Be Causing It?
Dr. Vinit Banga, Director of Neurology and Neurointervention at Fortis Hospital (Faridabad, India), explains that this symptom combination can stem from several potentially dangerous disorders:
Migraine with Aura
A common cause is migraine, especially those with visual disturbances such as flashing lights, blind spots, or blurred vision in one eye. These episodes may be triggered by:
-
- Stress
- Dehydration
- Hormonal fluctuations
- Certain foods
Optic Neuritis
This is inflammation of the optic nerve, often linked to multiple sclerosis or autoimmune diseases. It can cause:
-
- Sudden vision loss or blurriness in one eye
- Pain when moving the eye
Transient Ischemic Attack (TIA)
Also known as a “mini-stroke,” TIA may cause:
-
- Temporary vision loss
- Difficulty speaking
- Weakness in limbs It’s a critical warning sign of a possible full stroke and demands immediate emergency care.
Retinal Disorders
Conditions such as retinal detachment or retinal vein occlusion can lead to:
-
- Sudden vision loss in one eye
- Flashes of light
- Floating spots or shadows in the field of vision
Why You Shouldn’t Delay Medical Attention
Dr. Banga strongly advises against ignoring these symptoms. Early diagnosis is crucial to:
- Identify the exact cause
- Begin appropriate treatment
- Prevent serious complications such as permanent vision loss or stroke
