Can a popped blood vessel in my eye cause temporary blurred vision?

Question

If not, what else could cause blurred vision?

Answer 1

Quite often, a burst blood vessel in the eye is completely harmless. It should not cause blurred vision.

Blurred vision needs to be distinguished from other visual symptoms. Double vision (diplopia) is a specific visual symptom usually distinguished from blurred vision. It is important to determine whether only one or both eyes are affected (unilateral blurred vision versus bilateral blurred vision). Another distinction is whether the blurred vision occurs continually or only intermittently. Any type of blurry vision needs prompt professional medical diagnosis and treatment.

The following medical conditions are some of the possible causes of Blurred vision as a symptom. There are likely to be other possible causes, so ask your doctor about your symptoms.

    * Refractive eye conditions

    * Myopia

    * Near-sightedness

    * Presbyopia

    * Far-sightedness

    * Uncorrected vision disorder

    * Wrong eyeglasses

    * Eye irritation (see Eye symptoms)

    * Dry eyes - may cause blurred vision; see the many causes of dry eyes

    * Eye conditions

          o Cataracts

          o Glaucoma

          o Narrow angle glaucoma

          o Acute glaucoma

          o Macular degeneration

          o Senile macular degeneration

          o Diabetic lens osmosis

          o Iritis

    * Diabetes - due to diabetic lens osmosis or diabetic retinopathy in diabetes and diabetes-related conditions:

          o Undiagnosed diabetes

          o Poorly controlled diabetes

          o DKA

          o HHNS

    * Pregnancy

    * Migraine - causing visual effects prior to onset of the migraine.

    * Anemia - see also types of anemia

    * Certain kidney conditions

    * Certain nerve conditions

    * Certain brain conditions

          o Stroke

          o Transient ischemic attack

    * Temporal arteritis

    

* Some possible causes of intermittent blurred vision or episodes of blurred vision including:

          o Diabetic lens osmosis - blurred vision due to diabetes, DKA, HHNS, etc.

          o Glaucoma

          o Acute angle glaucoma - usually unilateral episodic blurring.

          o Multiple sclerosis

          o Transient ischemic attacks - i.e. multiple TIAs each causing blurring of vision.

          o Blood circulation disorders

          o Carotid insufficiency

          o Amaurosis fugax

          o Carotid embolism

          o Atherosclerotic emboli

          o Vertebrobasilar insufficiency - causing episodic blurring or double vision.

    * Visual hallucinations (see Vision distortion)

    * Amphetamine intoxication - in high doses.

    * Certain drugs

    * Digitalis toxicity
