The Symptoms Of Retinal Artery and Retinal Vein Occlusion

The symptoms of a retinal vein and retinal artery occlusion are similar. However, the symptoms of central retinal artery occlusion occur suddenly and require immediate treatment.

Contact our Lenexa, KS office serving Shawnee Mission right away if you have any of the following symptoms:

Blurred Vision or Blind Spots

An occlusion could cause blurry, distorted, or lost vision in a single part of your visual field, or your entire visual field.

Dark Spots

Seeing dark spots or floating lines is also a common symptom of artery and vein occlusions.

Eye Pain

Eye pain or pressure is a common symptom in retinal vein occlusion, but not retinal artery occlusion.

It has been about 20 years, but after three retina detachments over a period of about 90 days, Dr. Dyer took over on the third one and, essentially, redid everything the previous surgeon had done, but better...

I was referred to Retina Associates because of some vision problems. I went to the Overland Park location to see Dr. Savage. It was probably the best care I've had! They were quick and efficient and explained every step to me...

The Diagnostic Process

You should contact our medical professionals serving the Shawnee Mission area immediately if you have experienced sudden vision loss or other changes in vision. Central retinal artery and central retinal vein occlusion can lead to sudden and permanent vision loss if not treated as soon as symptoms appear. When you meet with our ophthalmologists, you can expect:

Medical History Review

Your doctor will review your full medical history so they will know if you are at a higher risk for developing one of these retinal conditions. 


Your doctor will apply eye drops to dilate your pupils and check your retina for signs of any blockage.


Your doctor may require additional tests such as fluorescein angiography (use of special dye and a camera to examine the retinal veins and arteries) or optical coherence tomography (taking digital cross-section images of the retina) to further examine the condition of your retina.

Retinal Vein Occlusion Treatment

Unfortunately, there is no cure for retinal vein occlusion. However, there are treatments that can help protect your vision and reduce any side effects or complications from the disease.

Your doctor could choose to use an anti-vascular endothelial growth factor injection. This injection helps ease the swelling by stopping or slowing the blood vessels from leaking or new blood vessels from forming. Steroid injections can also be used to help alleviate the swelling. A local anesthetic is applied before the injections so there is minimal discomfort.

Focal Laser Therapy

If the vein occlusion is causing fluid to build up in the macula (center of the retina), this laser therapy can cauterize the blood vessels in the back of your eye to keep them from leaking. This will reduce swelling and any pain associated with retinal vein occlusion. Since there are no pain receptors in the retina, you should feel no discomfort during this treatment.

Laser Surgery

If you have started to form new blood vessels, this surgery can help prevent new ones from forming by making tiny burns along the retina. 

Retinal Artery Occlusion Treatments Timing Is Everything

Treatment for retinal artery occlusion must be given within a few hours of the onset of symptoms. When given in a timely manner, these treatments can help to restore your vision:


Inhaling a mixture of carbon dioxide and oxygen causes the arteries to dilate and helps to release the occlusion.

Fluid Removal

Your doctor may be able to remove some of the fluid to help the clot move past your retina.


A clot-busting drug can be used to help remove the block and alleviate your symptoms.

Insurance Will Cover Retinal Procedures Don't Delay Treatment 


Your medical insurance will contribute to the cost of treatment we provide at our practice serving Shawnee Mission, KS. Our staff will gladly work with your provider to secure the maximum coverage.

Absolutely the best care especially for diabetics who may unfortunately suffer from diabetic retinopathy.  Dr. Cohen made it possible for me to see again and you cannot put a price on that.  They will work with you on payment.  Everyone is genuinely concerned for your health and wellbeing.  The miracles performed at Retina Associates are amazing.  Thank you

... I have recommended Dr. Singh and Retina Associates to everyone who asked for an ophthalmologist recommendation, including two of my brothers.  Dr. Singh is attentive and empathetic; he explains both treatment and condition in a way I am able to comprehend. I get a shot in my eye almost every visit and Dr. Singh is gentle, so gentle, I rarely feel when he administers the shot.  His team is also amazing - friendly, fun, and efficient...
