What is the difference between diabetic retinopathy and hypertensive retinopathy?

What is the difference between diabetic retinopathy and hypertensive retinopathy?

Hypertensive retinopathy and diabetic retinopathy, while being similar in some features, show up differently on the retina. Hypertensive retinopathy has relatively few hemorrhages and a greater number of “cotton wool” spots than diabetic retinopathy, although there is little to differentiate the two for the patient.

What is hypertensive retinopathy?

Hypertensive retinopathy is retinal vascular damage caused by hypertension. Signs usually develop late in the disease. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema.

Does hypertensive retinopathy have neovascularization?

Ischemia secondary to vascular occlusions can cause neovascularization, vitreous hemorrhage, epiretinal membrane formation, and tractional retinal detachment. Hypertension also leads to more advanced diabetic retinopathy progression.

What is the treatment for hypertensive retinopathy?

Your doctor may prescribe blood pressure medications such as diuretics, beta-blockers, or ACE inhibitors. You can control this condition by controlling your blood pressure. If your condition is severe, however, you may have irreversible eye damage that causes permanent vision problems.

Can hypertensive retinopathy be cured?

Q: Can hypertensive retinopathy be reversed? A: It depends on the extent of damage to the retina. In many cases, the damage caused by hypertensive retinopathy can slowly heal if the necessary steps to lower one’s blood pressure are taken.

Can you recover from hypertensive retinopathy?

Outcome. The retina will usually recover if the blood pressure can be controlled, but a grade 4 level of retinopathy is likely to involve permanent damage to the optic nerve or macula.

What is the treatment of hypertensive retinopathy?

Can you reverse hypertensive retinopathy?

How quickly does retinopathy progress?

Typically, diabetic patients will develop diabetic retinopathy after they have had diabetes for between 3-5 years. In the early stages, diabetic retinopathy will not affect the sight, but if it is not treated and progresses, eventually the sight will be affected.

How long does hypertensive retinopathy last?

The retinal changes can be halted when hypertension is treated. However, arteriolar narrowing and AV changes persist. For untreated malignant hypertension, the mortality is high as 50% within 2 months of diagnosis and almost 90% by the end of 1 year.

What’s the difference between diabetic and hypertensive retinopathy?

Hypertensive retinopathy (HR) is a complication of Htn that leads to damage to the retina and retinal circulation due to high BP. Usually they are asymptomatic but may present with decreased vision or headache. Diabetic Retinopathy (DR) is a complication of DM that can lead to blindness. The longer the disease, the higher risk to get DR.

Is there a cure for diabetic and hypertensive retinopathy?

Hypertensive retinopathy (Bonnet Sign, silver wiring) plus diabetic retinopathy A California legislator recently introduced Senate Bill 492, which would allow optometrists to treat chronic systemic problems, such as hypertension.

Can a hypertensive retinopathy cause optic neuropathy?

Hypertension can cause retinopathy,optic neuropathy, and choroidopathy,. This article focuses upon hypertensive retinopathy, which is the most common ocular presentation, but also includes hypertensive optic neuropathy and choroidopathy. Hypetensive retinopathy includes two disease processes.

What happens in the exudative phase of hypertensive retinopathy?

Hypertensive retinopathy goes through vasoconstrictive, sclerotic, and exudative phases based upon the extent of hypertension control. In the vasoconstrictive phase, due to the elevated luminal pressures, local autoregulatory mechanisms cause retinal arteriole narrowing and vasospasm to reduce flow.
