CENTRAL RETINAL ARTERY OCCLUSION (CRAO)

CRAO disease of eye which occurs when the central retinal vein get occluded, or blocked, obstructing retinal blood flow from the eye affecting visual acuity, the sharpness or clarity of vision.

CENTRAL RETINAL ARTERY OCCLUSION (CRAO)

CRAO disease of eye which occurs when the central retinal vein get occluded, or blocked, obstructing retinal blood flow from the eye affecting visual acuity, the sharpness or clarity of vision.

CRAO can be divided into 2 clinical types, ischemic and non-ischemic.

“In Ayurveda eye diseases have been mentioned in details in Ancient Text Sushrut Samhita. Diseases of retina are mentioned in drishti patal roga."

N-ISCHEMIC CRAO

In case there is very limited obstruction of blood flow in the capillaries. Complications such as macular edema can occur in the non-ischemic (or perfuse) form.

ISCHEMIC CRAO

In case blood flow in the retinal capillaries is more widely obstructed. It's more severe form of CRAO in which vision is likely to be poor and develop complications, as neovascularization.

Ayurvedic view for CRAO and CRAO

Three doshas Vata, Pitta and Kapha are observed and certain condition that leads to imbalance in the three doshas worsen the condition causing the disease.

Symptoms:

  • Sudden blindness in one of your eyes
  • Sudden, complete blurring of vision in one eye
  • Gradual loss of vision in one eye over a few weeks
  • Symptoms might be for few seconds or minutes or may be permanent
  • Sometimes pain in eye

Causes

  • The blockage usually occurs due to a clot or fatty deposit in the blood vessel.
  • Embolism and Thrombosis
  • Temporal Arteritis
  • Vasculitis
  • Trauma
  • Glaucoma

CENTRAL RETINAL VEIN OCCLUSION (CRAO)

The blockage in CRAO causes the walls of the vein to leak blood and excess fluid into the retina. When this fluid collects in the macula (the area of the retina responsible for central vision),and causes swelling called Macula Derma. It decreases the activity of Retina which results in blurred vision.
