What does CRVO look like?

Central retinal vein occlusion (CRVO) is a common retinal vascular disorder. Clinically, CRVO presents with variable visual loss; the fundus may show retinal hemorrhages, dilated tortuous retinal veins, cotton-wool spots, macular edema, and optic disc edema.

Can CRVO go away?

There is no treatment available for CRVO but there are treatments for the complications related to CRVO. Injectable medications and steroids can be used to treat macular edema.

How long does CRVO last?

The effect of Ozurdex implant lasts for 4-6 months so the implant must be repeated regularly over a 2-3 year period as a minimum.

Can you drive with CRVO?

You may be able to continue driving a car or motorcycle if the vision in your other eye is unaffected by other eye conditions, and can meet the visual requirements for driving.

Is a CRVO painful?

Blood in the vitreous clumps and is seen as tiny dark spots, or floaters, in the field of vision. In severe cases of CRVO, the blocked vein may cause painful pressure in the eye. Ischemic CRVO can also cause neovascular glaucoma.

Can CRVO happen in both eyes?

CRVO that occurs in both eyes at the same time can be related to systemic disease; in these cases, a tendency toward abnormal blood clotting is definitely more common and medical testing to detect so-called “hypercoagulable states” is indicated.

How bad is CRVO?

In severe cases of CRVO, the blocked vein may cause painful pressure in the eye. Ischemic CRVO can also cause neovascular glaucoma. This type of glaucoma is caused when abnormal blood vessels begin to grow inside the eye, causing the pressure in the eye to rise.

Is retinal vein occlusion painful?

The symptoms of retinal vein occlusion range from subtle to very obvious. There is painless blurring or loss of vision. It almost always happens in just one eye. At first, the blurring or loss of vision might be slight, but it gets worse over the next few hours or days.

Laser, surgery, eye drops, and glasses do not help to improve vision. With time, a minority of patients may experience a spontaneous improvement in vision. However, in most cases the vision remains the same or worsens without treatment.

Can CRVO cause headaches?

The comparison between RVO and controls displayed a higher proportion in the RVO group for (in order of the higher risk): migraine headache (CRVO: 21\%, BRVO: 47\%, controls: 13\%, p=0.008), hypertension (CRVO: 52\%, BRVO: 63\%, controls: 37\%, p=0.012), glaucoma (CRVO: 33\%, BRVO: 22\%, controls: 16\%, p=0.034), antiaggregant …
