HIGH SEVERITY

A blockage of the small veins that carry blood away from the retina. Can be central (CRVO) or branch (BRVO). Second most common retinal vascular disease after diabetic retinopathy.

Global Affected

16.0M

Countries

19

Symptoms

Sudden blurred vision
Loss of vision
Floaters
Pain (in severe cases with neovascularization)
Visual field defects

Treatment Options

Anti-VEGF injections
Intravitreal steroid implants
Laser photocoagulation
Panretinal photocoagulation (neovascularization)
Management of systemic risk factors
Aspirin therapy (controversial)

Risk Factors

1Age (over 50)
2Hypertension
3Diabetes
4Glaucoma
5Hyperlipidemia
6Smoking
7Obesity
8Cardiovascular disease
9Blood clotting disorders

Diagnostic Methods

  • 1Dilated eye exam
  • 2Fluorescein angiography
  • 3OCT
  • 4Ophthalmoscopy
  • 5Blood pressure measurement
  • 6Blood tests (lipids, glucose)

Prognosis

Variable. Vision recovery depends on type and treatment. CRVO has worse prognosis. Recurrence possible. Complications include neovascularization, glaucoma. Requires ongoing monitoring.

Prevention

  • Control blood pressure
  • Diabetes management
  • Don't smoke
  • Regular exercise
  • Healthy diet
  • Regular eye exams
  • Manage cholesterol

Research Status

Anti-VEGF injections (aflibercept, ranibizumab) standard of care. Intravitreal steroids (dexamethasone) alternative. Laser photocoagulation for non-perfusion. Manage cardiovascular risk factors. Treat macular edema. Neovascularization requires prompt treatment.
