Overview

Blurry vision is a common ophthalmic symptom where vision becomes less sharp and there is an inability to see small details.Alterations of the optical surfaces or media for which the visual axis travels typically causes blurred vision. Refractive errors, such as near-sightedness and far-sightedness cause the majority of blurred vision complaints. Most vision complaints can be corrected with glasses

Diagnosis

History and Symptoms

• Detailed history important, including the following:

  • Duration of symptoms
  • Progression of symptoms
  • Near or far sighted
  • Permanent or transient
  • Binocular or uniocular

• Past medical history
• Associated symptoms

Physical Examination

Eyes

• Complete ophthalmologic exam including:

  • Slit lamp examination
  • Dilated fundus exam
  • Visual acuity
  • Improvement of vision with pinhole
  • Dry or irritated eyes

Ear Nose and Throat

Palpate the temporal area to determine if there is pain in the temporal area to suggest temporal arteritis

• Neurologic exam if necessary

Laboratory Findings

• Complete blood count (CBC)
• Fasting or random blood sugar

  • Repeat glucose (if initial glucose is elevated)

• Prothrombin time (PT)
• Partial thromboplastin time (PTT)

Electrolyte and Biomarker Studies

Check erythrocyte sedimentation rate to rule out temporal arteritis

Other Imaging Findings

• Electroencephalogram (EEG) if seizures are suspected

Treatment

• Treat underlying pathologies
• For dry eyes, lubrication
• Appropriate treatment for hyperviscosity

Acute Pharmacotherapies

• Antiseizure prophylaxis (seizure disorders)

Surgery and Device Based Therapy

• Glasses or contact lenses for blurred vision due to refractive errors
• Possible surgical repair for retinal detachment
• Temporal artery biopsy may be needed
