HOW DOES YOUR CONDITION
IMPACT YOUR VISION?
IMPACT YOUR VISION?
A healthy retina and macula are essential for normal vision.
DIABETIC MACULAR EDEMA (DME)
- Damage to the small blood vessels in the eye can lead to diabetic eye disease (retinopathy)
- Fluid leaking from these blood vessels may cause the central part of the retina (the macula) to swell. This is called DME
- Macular edema (swelling of the macula) is the most common cause of vision loss in people who have diabetic retinopathy

- You may not have any symptoms if your doctor finds DME early
- Can lead to blurry central vision, with blurriness ranging from mild to severe
- Can cause significant vision loss over time
MACULAR EDEMA (SWELLING OF THE MACULA) FOLLOWING RETINAL VEIN OCCLUSION (RVO)
- Blood circulating through the retina leaves the eye by draining into the retinal vein
- A retinal vein occlusion is a blockage that prevents normal blood flow out of the eye
- A blockage may affect the main vein leaving the eye (central retinal vein occlusion [CRVO]) or one of the smaller, branch veins that lead to the main vein (branch retinal vein occlusion [BRVO])
- RVO is more common once people reach middle age
These pictures show bleeding that may happen in the retina when a retinal vein becomes blocked in someone who has BRVO or CRVO.
- Sudden blurring or vision loss in all or part of one eye are most common
- For some patients, the vision loss may last for a few seconds or minutes or may be permanent
- The amount of blurring or vision loss depends on how much damage to the retina has occurred
AFFECTING THE BACK SEGMENT
OF THE EYE
- Uveitis (pronounced you-vee-eye-tis) is inflammation of the uvea, which is the middle layer of the eye
- Uveitis can also affect the retina and blood vessels of the eye
- Inflammation is caused by retinal cells, your immune system’s white blood cells, and the chemicals these cells release
- Noninfectious uveitis means that although the uvea is inflamed, no bacteria or viruses are found in the eye
- The cause of the inflammation with noninfectious uveitis is often unknown

- Decreased vision and irregular floating black spots (floaters)
- Vitreous haze (cloudiness) can also contribute to decreased vision
- More severe disease may lead to significant loss of vision
