Imran Khan CRVO disease इस्लामाबाद, एजेंसियां। पाकिस्तान के पूर्व प्रधानमंत्री इमरान खान की सेहत को लेकर एक बार फिर गंभीर चिंता जताई जा रही है। जेल में बंद इमरान खान को आंखों की खतरनाक बीमारी CRVO (सेंट्रल रेटिनल वेन ऑक्लूजन) होने की बात सामने आई है। उनकी पार्टी पाकिस्तान तहरीक-ए-इंसाफ (PTI) का दावा है कि यदि समय रहते इलाज नहीं हुआ, तो उनकी आंखों की रोशनी स्थायी रूप से जा सकती है। PTI के…

Central retinal vein occlusion (CRVO), is a medical condition in which there is a blockage of blood flow to the retina. A blockage in the central retinal vein can result in blurry or sudden loss of vision.

There are two types CRVOs:

· Non-ischemic CRVO: This type of CRVO is not a symptom of an ischemic condition. The blood flow to the retina is only partially impeded and there is no damage to the retina.

· Ischemic CRVO is: This type of CRVO is more severe and has a lower blood flow to the retina. This can lead to irreversible damage to the retina, and even more severe vision loss.

The most common cause of CRVO is a combination or combination of hypertension, diabetes, high blood cholesterol, and other medical conditions. These conditions can damage the blood vessels within the eye. This condition is more common in people over 65 and those with a history or cardiovascular disease.

The severity and extent of the damage to the retina will determine the treatment for CRVO. This may involve medications, laser therapy or surgery. It is crucial to have your vision checked by an eye doctor immediately in order to avoid further damage or vision loss.

What are the causes of Central Retinal Vein Occlusion?

Central retinal vein obstruction (CRVO), is usually caused by a combination factors. These factors include:

Blood clotting disorders: Conditions such as thrombophilia that increase blood clot risk can increase the likelihood of CRVO. High blood pressure: Hypertension may cause damage to the blood vessels and increase the chance of developing CRVO. Diabetes: High blood sugar can cause damage to the blood vessels and increase the chance of developing CRVO. High cholesterol: Plaque buildup in blood vessels can lead to high cholesterol levels, which could increase the risk for CRVO. Glaucoma: People with glaucoma (a condition that increases pressure in the eyes) may be at greater risk for developing CRVO. Aging: CRVO occurs more frequently in older people, and the risk of developing it increases with age.

Although it may not be possible to pinpoint the exact cause of CRVO, there are usually a number of factors that damage blood vessels and increase the likelihood of obstructions or blockages in the central retinal vessel.

What are the symptoms of Central Retinal Vein Occlusion?

The severity and extent of damage to the retina may affect the symptoms of central retinal vessel occlusion (CRVO). The following are some common signs of CRVO:

Sudden, painless vision loss in one eye Vision blurred or distorted Perimeter vision impairment It is difficult to distinguish colors You may see floaters and dark spots in your visual field. Eye discomfort or pain

Depending on the severity of the damage to the retina and how much of the blockage they are causing, symptoms of CRVO can appear suddenly or gradually. To prevent further damage to your retina and to reduce the chance of vision loss, seek immediate treatment from an eye doctor if you have any of these symptoms.

What is the treatment for Central Retinal Vein Occlusion?

Treatment for central retinal vein obstruction (CRVO), depends on the severity and extent of the damage to the retina. While the blockage can sometimes be resolved on its own in some cases, it may require treatment to prevent further damage to your retina and decrease the chance of vision loss. There are several common treatments for CRVO:

Lifestyle changes: Reducing the chance of further damage to your retina can be achieved by managing underlying conditions like high blood pressure, high cholesterol and diabetes.

Each case is unique and each patient's needs will dictate the treatment that is chosen. It is crucial to have your retina evaluated promptly and to receive treatment from an eye doctor to reduce the chance of further damage and to keep your vision clear.

Avastin as Effective as Eylea for Treating Central Retinal Vein Occlusion

Monthly eye injections of Avastin (bevacizumab) are as effective as the more expensive drug Eylea (aflibercept) for the treatment of central retinal vein occlusion (CRVO), according to a clinical trial funded by the National Eye Institute (NEI), part of the National Institutes of Health. After six monthly injections, treatment with either drug improvedvisual acuity on average from 20/100 to 20/40.

I'm going to go ahead and make a post about this because:

My doctors all seem to be shocked that I developed this at my age.

More young people are diagnosed with this in recent times.

In my case, it was probably preventable.

CRV/CRVO (central retinal vein occlusion) is common in the older population and to those with diabetes and/or high blood pressure.  It's less commonly known but also commonly diagnosed in people who have been dehydrated.  Women taking an oral contraceptive pill are also at risk, and are discouraged from taking oral contraceptives if they have been diagnosed (I wasn't told about this upon diagnosis).  There are not a lot of treatment options, and there really is no cure at the moment.  It can be painful, it can lead to glaucoma, and/or total vision loss, etc. if left unchecked.  

Basic overview:  CRV is caused when a blood clot or the like creates a blockage in the central vein in the retina.  It usually only occurs in one eye at a time, but can be present in both.  Extra veins develop in the eye because of the blockage, creating a huge problem for the nerves transmitting signals to the brain. 

"In these cases, the retina becomes so "starved" for oxygen that new blood vessels grow in various locations in the eye to improve the insufficient blood supply. Unfortunately these new vessels are in dangerous locations and are fragile and not properly formed leading to a variety of problems including a very dangerous type of blinding glaucoma" - http://www.bayerpharma.com/en/therapeutic-areas/therapeutic-areas-a-z/central-retinal-vein-occlusion-crvo.php

Recently, I found out that the huge blind-spots I was experiencing a year prior to being diagnosed with CRV were an early warning sign of the disease.  When I initially went to see my eye-doctor about the blind spots, I was told that what I was seeing were floaters, and that I shouldn't worry about them.  (I had an exam done, but they did not check for this condition)

About a year later, I woke up with sudden, massively decreased vision in one of my eyes.  This time, the doctor was very compliant and scheduled me for in-depth testing right away.  This is when I was diagnosed. 

Prior to all this, I was diagnosed as being dehydrated (long-term), which is more common in young people than were are told.  Symptoms of dehydration don't just include thirst.  After long periods of dehydration, you stop feeling thirsty.  Signs do include dizziness upon standing up, involving an increased heart-rate, fatigue, general malaise, and shortness of breath.  These are common symptoms with a lot of different and unrelated conditions, so only your doctor can determine what is causing them.  But it is a good idea to ask.

The treatment for dehydration, by the way, is fairly simple.  If you can't resupply your system with enough fluid on your own, the doctor will prescribe a visit to the ER for an IV treatment.  They will keep you there all day, if not longer.  It's not fun.  Drink lots.  

CRV is only one of many long-term complications of being dehydrated, so make sure you keep hydrated!  It doesn't just apply to when you're out hiking, exercising, or exposed to heat.  Every day, make sure you get enough to drink.  <333
