Are there any stages of Hypertensive Retinopathy?
Keith and Wegner have classified hypertensive retinopathy into 4 stages:
Grade I: In Grade I, there is a mild narrowing of the retinal artery.
Grade II: They are similar to Grade I, but they are more severe or tighter constrictions of the retinal artery. This is called Arteriovenous (AV).
Grade III: There are signs of Grade II with retinal oedema, micro aneurysms, cotton wool spots and retinal haemorrhage.
Grade IV: Has severe signs of Grade III along with optic disc swelling called papilledema and macular oedema.
What are the complications of Hypertensive Retinopathy?
- Ischemic Optic Neuropathy: – It is a medical condition involving loss of vision due to the damage to the optic nerve from insufficient blood supply.
- Retinal artery occlusion: – It is caused by the embolism (blockage) in one of the small arteries that carry blood to the retina.
- Retinal vein occlusion:- It is caused by the blockage of the small veins that carry blood away from the retina.
- Malignant hypertension:- Malignant Hypertension is extremely high blood pressure that develops rapidly and causes some type of organ damage.
- Nerve fibre layer ischemia:- Damage to the nerve fibres may lead to cotton-wool spots, which are fluffy white lesions on the retina.
