Retinal Vein Occlusion (RVO)

What is Retinal Vein Occlusion (RVO)?

Retinal Vein Occlusion (RVO) is a serious eye problem that affects people with different complications such as swelling, eyesight issues, and permanent blindness (vision loss) when a vein of the affected individuals’ retina gets clogged due to storage of blood and fluid that impacts retina, a light-sensitive tissue at the back of the eye which plays a crucial role in healthy vision. So, RVO shouldn’t be ignored by the old patients as any negligence on their part may cause partial or permanent blindness to them.

There are two main types of RVO:-

Branch Retinal Vein Occlusion (BRVO) – This occurs when one of the smaller branches of the main retinal vein is blocked.
Central Retinal Vein Occlusion (CRVO) – Such situation takes place when the central vein circulating blood from the retina is clogged or chocked.

Symptoms & Causes

Symptoms:-

Abrupt Blindness or Eyesight Problem in one Eye.
Distorted or wavy vision.
Dark spots or floaters in your vision.
A “curtain” falling over part of your visual field.

Symptoms can vary depending on whether you have BRVO or CRVO, but both types often lead to vision problems that may worsen over time.

Causes:-

Following are the common causes of RVO:-

Atherosclerosis (Hardening of the arteries) – When the blood vessels get contracted/narrowed, veins of the retina is blocked.
High blood pressure – High BP or Hypertension causes risk of RVO by damaging blood vessels.
Diabetes – Low sugar also is one of the common causes of RVO.
Glaucoma – It restricts blood flow that causes problem of RVO clogging Retinal Vein.
Blood disorders – Conditions that increase the thickness of the blood can also contribute to blockages.

Diagnosis & Tests

To diagnose RVO, an ophthalmologist will typically perform the following tests:-

Dilated eye exam – The doctor will dilate your pupils to get a clear view of the retina.
Fluorescein angiography – A special dye is injected into a vein, and images are taken to show how blood flows through the retina, helping to detect blockages.
Optical Coherence Tomography (OCT) – This imaging test creates detailed pictures of the retina to check for swelling and other abnormalities.
Blood tests – These may be done to identify underlying conditions like diabetes, high cholesterol, or blood clotting disorders.

Management & Treatment

RVO treatment focuses on preventing further damage and restoring vision as much as possible:-

Anti-VEGF injections – These medications, such as Ranibizumab or Bevacizumab, are injected into the eye to reduce swelling and prevent new blood vessel formation, which can damage the retina.
Corticosteroid injections – Steroids can help reduce inflammation in the retina.
Laser therapy – Laser photocoagulation is used to seal off leaking blood vessels or to prevent abnormal new blood vessel growth.
Surgery – In rare cases, vitrectomy (removal of the gel-like substance in the eye) may be necessary to treat more severe cases of RVO.

Prevention To reduce the risk of RVO:-

Control high blood pressure – Keep blood pressure in check with medication and lifestyle changes.
Manage diabetes – Ensure blood sugar levels are well-regulated.
Lower cholesterol – Diet, exercise, and medication can help lower cholesterol levels, reducing the risk of a blockage.
Quit smoking – Smoking damages blood vessels and increases the risk of RVO.
Regular eye exams – Annual checkups help monitor eye health and catch potential problems early.

Outlook / Prognosis

The outlook for individuals with RVO depends on the severity of the blockage and how quickly treatment is administered. While some people recover vision with treatment, others may experience permanent vision loss. Early diagnosis and prompt treatment significantly improve the chances of a good outcome.

Living With

Living with RVO requires regular eye care and medical follow-ups. Managing underlying conditions like high blood pressure or diabetes is critical to prevent further complications. Many patients can adapt to partial vision loss with support, including visual aids or lifestyle adjustments.

By addressing risk factors and staying vigilant with eye care, patients with RVO can maintain the best possible quality of life.
