Retinal Health is an Important Aspect of Long-Term Wellness

What is the Retina?

When we think of our eyes, we may know there are multiple working parts. There is the lens that takes in light, and the cornea, through which light travels on its way to the back of the eye. It is here, at the back of the eye, where the retina is positioned. This thin layer of tissue has numerous light-sensitive cells that transmit light as neural signals. These signals pass through the optic nerve to the brain, where visual recognition is formed. Both the optic nerve and the retina are outgrowths of the brain. Both are vital to the quality of our vision.

How the Retina Affects Vision

There are two kinds of cells on the retina: cones and rods. These cells are called photoreceptors and each work in a specific way to formulate visual images:
•Cones are cells that live in the macula, the central part of the retina. Cones are cells that detect color and detail. Within the macula, cones facilitate functions including reading and writing, typing and texting, and recognizing small details of appearance in an object or person.
•Rods are cells situated along the outer border of the retina. These photoreceptors are involved in managing vision at night and in areas where lighting is poor.

Signs of Retinal Problems

There are a few ways in which the retina may be affected, from a tear to diabetic retinopathy to detachment. Symptoms include:
•Persistent blurry vision.
•Flashes of light in one or both eyes. This may occur upon blinking.
•Sudden onset of dark spots across the field of vision (floaters).
•Progressive reduction in peripheral vision. This may appear as a dark shadow at the outer field of vision.

Signs of retinal problems may not become obvious until substantial damage has occurred. It is important to obtain routine dilated eye exams from an ophthalmologist, especially if you have diabetes.

Treating Retinal Damage

Sudden signs of visual disturbance need to be examined right away. If you are experiencing sudden floaters or flashes, obtain immediate medical attention. With prompt care, retinal tears and detachment can be repaired and vision preserved.

There are several ways in which retinal conditions may be treated. A board-certified retinal specialist can be expected to recommend treatment based on the type and severity of the problem. In some cases, a laser device can seal the borders of a retinal tear. Tears can also be “frozen” (cryotherapy). If the retina has detached, it may be repaired with a scleral buckle or gas bubble to hold the proper position.

Is Posterior Vitreous Detachment Serious?

Eye conditions have a way of sounding complicated. What sounds complicated, especially as it pertains to our health, can also sound frightening. Posterior vitreous detachment may be a mouthful but, rest assured, a retinal specialist knows how to diagnose and treat this condition efficiently. The key is getting the right care at the right time.
Vitreous detachments can set off a sudden flurry of floaters. Floaters are the appearance of dark or lighted spots that travel across the field of vision. The condition is relatively common and can usually be treated successfully after a thorough, dilated eye exam confirms the extent of detachment.

What is Vitreous Detachment?

Between the lens and cornea at the front of the eye and the retina and optic nerve at the back of the eye is a substantial area of space (80 percent of the total volume). This space is filled with what we call vitreous or vitreous fluid. The vitreous is typically gelatinous, somewhat like Jell-O. As we age, the collagen fibers that stabilize the vitreous to structures at the front and back of the eye begin to degrade. This deterioration of collagen subsequently causes the vitreous to break down into more of a liquid substance. The destabilized gel contracts and tugs on the retina. Sometimes tugging is all that happens but, in some instances, the vitreous separates from the retina altogether.

This Sounds Serious!

The thought of different structures in the eye separating sounds serious. We understand why. However, research has indicated that a detached vitreous is less of a concern than one may imagine. It is better for collagen fibers to disconnect than to remain attached and pull on the retina. When this happens, there is a risk that the retina could tear or separate from the back of the eye. It is these two issues that cause a concern for vision loss.

Retinal Tears and Detachments can be Treated

The team at VitreoRetinal Surgery has extensive experience in the diagnosis and treatment of retinal tears and detachments. We can also help our patients understand their risk for vitreous and retinal detachments.

All Eye Doctors are Not the Same

When it comes to your eyes, there are several aspects to consider. Many people make the mistake of thinking that their annual vision checkup is sufficient eye care. There is much more to the eyes than how well they focus on objects at various distances. To really know your eye health and be able to protect it as you age, it is necessary to know how eye specialists differ from one another. Here, we look at the optometrist, the ophthalmologist, and the retinal specialist.

What Is an Optometrist?

An optometrist is the eye specialist who examines your vision. This OD, or doctor of optometry, can address refractive conditions like nearsightedness, farsightedness, and presbyopia, among others. An optometrist can also diagnose and treat eye infection and dry eye syndrome. If a potentially serious eye condition is suspected by an optometrist, a referral may be made to an ophthalmologist.

What Is an Ophthalmologist?

An ophthalmologist is a medical doctor who has extended their medical education another few years beyond four years of medical school to specialize in vision care and diseases of the eye. The extensive training an ophthalmologist completes enables them to diagnose and treat a wide variety of eye diseases, including cataracts and glaucoma, and treat them with medication or surgery.

What is a Retina Specialist?

A retinal specialist is an ophthalmologist who has extended their education another one to two years after a three-year ophthalmology residency. The additional education focuses on conditions and diseases that specifically affect the retina and vitreous, the clear gel that fills the central part of the eye. The retinal specialist typically sees patients that are referred by their general ophthalmologist for confirmation and treatment of some type of retinal injury or disease. Treatment often involves advanced surgical techniques or the latest, proven nonsurgical modalities.

What Floaters and Flashes have to do with Retinal Health | VitreoRetinal Surgery, PA | Minneapolis MN

Common Questions about Floaters

As retinal specialists, we frequently hear questions about visual distortions. Floaters, the appearance of a speck of light or foreign object drifting across the field of vision, are quite common. Here, we want to discuss the questions that our patients ask and what you need to know if you begin to notice floaters in your own vision.

What is an eye floater?

A floater is the appearance of some type of spot or worm-like shape moving across the eye. The “spot” is actually a clump of protein that has formed inside the eye.

How can I identify a floater?

Floaters appear in a number of forms. Some people describe floaters as cobwebs moving through their vision when they are looking at a broad, blank visual field. A floater may look like hairs, birds flying way off in the distance, black dots, or bright lights. Floaters may move along with the eye as observation moves from one object to another. Sometimes spots move when observation stays on a singular object. Often, when a person tries to catch on to a floater, the apparition disappears momentarily.

What causes floaters in the eye?

Floaters are made up of protein molecules in the eye. These clumps of proteins develop because, with age, the gel-like fluid that fills most of the space in the eye changes in consistency. Instead of staying dense and gelatinous, the vitreous becomes more fluid and watery. As this happens, clumps of protein have nothing to do but float. When they do, they cast shadows onto the retina as light passes through the eye. It is the shadows on the retina that appear as floaters in the field of vision.

Typically, floaters are a visual distortion that is related only to the aging process. Eye injury or a retinal tear or detachment could also cause floaters.

Should I be concerned about floaters?

Most adults experience floaters at some point as their vitreous matter changes. Floaters are typically not perceived as dangerous, except in instances in which numerous floaters appear suddenly.

The sudden onset of floaters in the eye could indicate a retinal tear or detachment, which occurs when the shrinking vitreous pulls on the retina at the back of the eye. Depending on the degree of tugging, the retina may partially detach from the back wall of the eye. A retinal tear or detachment may also cause symptoms such as shadowing across the field of vision. If severe floaters and shadowing come on quickly or worsen quickly, emergency medical care should be sought.

Floaters should not be a significant cause for concern. However, if spots in your field of vision are disruptive, you may benefit from treatment with a retinal specialist.

We are pleased to serve patients in areas including Duluth, St. Cloud, Edina, and more. For more information on retinal services, call (800) VRS-2500.

What is Posterior Vitreous Detachment and is it Serious?

Any term that refers to the body and includes the word “detachment” can sound frightening. Posterior vitreous detachment is an eye condition that sounds far worse than it may be. In some cases, treatment never becomes necessary. In some cases. Because there is a slight chance that symptoms of posterior vitreous detachment could indicate a serious eye problem, it is critical that an ophthalmic exam takes place right away.

How to Spot Vitreous Detachment

The number one indicator of a potential threat to your eyesight is the sudden onset or increase in floaters. This visual phenomenon looks like tiny shapes or spots of light that drift across your visual field when you move your eyes from one object to another.

The reason that floaters occur is that the vitreous, or gel-like substance that fills the space between the front and the back of the eye, degrades. The vitreous is tethered to a base near the front of the eye by small collagen fibers. These fibers are also present at the back of the eye to secure the vitreous to the retina and the optic nerve.

Over time, collagen fibers throughout the whole body begin to break down, including in the eye. This deterioration of collagen leads to the liquefication of the vitreous. The gelatinous matter becomes somewhat unstable and fluid, causing contraction that may separate the vitreous from the back of the eye. Floaters signify the stringy strands of the degrading vitreous casting shadows on the retina.

Usually, floaters decrease spontaneously over a few months’ time and no further symptoms occur. The collagen fibers that once connected the vitreous to one of its bases break away and no permanent damage is done. Sometimes, though, the fibers do not break easily. Instead, they pull on the retina and pose a risk of tear or retinal detachment.

Very few people who experience posterior vitreous detachment also develop retinal problems. If the retina were to tear or detach, treatment would need to be administered right away to seal this part of the eye. This is often done with cryotherapy or laser therapy or, in some cases, surgery to reattach the retina. When conducted early, treatment for retinal tears and detachment is over 90 percent successful.

Cryotherapy for Retinal Disease

You may have heard of cryotherapy as a treatment for warts or early skin cancers. You may have even heard about the health benefits of whole-body cryotherapy, such as faster tissue healing and inflammation-control. The fact of the matter is that science has discovered a multitude of ways to utilize this technology, including helping people with retinal disease.

Retinal Cryotherapy

The retina is a critical part of the eye, located at the back of the eye where light is supposed to land after passing through anterior structures like the cornea. The retina is a thin piece of tissue but one that fulfills an important role in vision. In the retina are cells called rods and cones, each is very sensitive to light and picks up visual details from light to pass onto the brain via the optic nerve. Being that the retina is so sensitive, this part of the eye is also susceptible to damage. For example:

  • Blood supply to the retina may be blunted by irregularly shaped or damaged blood vessels.
  • Tumors may develop on the retina (retinoblastoma).
  • The retina may become ischemic due to the low oxygen supply.
  • The retina may partially or completely detach.

Because the retina transfers light to the optic nerve for translation into visual images, damage to this part of the eye will cause some degree of visual disturbance. Depending on the problem and its severity, the disruption may range from blurriness to vision loss. Retinal cryotherapy provides your retinal specialist with a way to counter certain problems.

Retinal cryotherapy is a treatment in which extreme cold is utilized to create scar tissue in the retina in a precisely controlled manner. The formation of scar tissue causes “tissue destruction” that subsequently provokes a healing response in which retinal tissue is regenerated. Using retinal cryotherapy, it may be possible to restore vision to some extent, sometimes completely.

How Your Blood Pressure Can Affect Retinal Health

The average life is an awfully long time to live with unpleasant eye conditions. As retinal specialists, it is our mission to help people maintain a good quality of life by handling various forms of eye disease or injury; but first, we have to know they exist. It isn’t enough for us to understand this, you also need to be aware of the particular risks your eyes may face. One that we’d like to discuss here is your blood pressure.

High blood pressure, referred to as hypertension, is a common health condition that is typically thought to affect cardiovascular health. Rarely do we make the jump straight from observing an increase in pressure in the body’s veins when the heart beats to wondering how that will affect the eyes. The thing about high blood pressure is that it can affect any vein anywhere in the body. Because the blood vessels in the eye are particularly small and delicate, they may be more susceptible to problems related to high blood pressure.

Hypertension and Your Eyes

When a person has high blood pressure, there is more force placed on the blood vessels than is normal and healthy. Increased pressure in the veins can degrade their walls, causing swelling. In the eyes, this can lead to leakage. What is of concern about high blood pressure is that the increase in vascular force does not occur with symptoms; it can go on for years without anyone knowing. This is why adults of all ages are encouraged to schedule annual health checkups during which blood pressure and other screenings are performed. Without you even knowing you have high blood pressure, your eyes could be suffering progressive and irreparable damage.

The eye condition related to high blood pressure is referred to as hypertensive retinopathy. Though no obvious symptoms may alert you to this condition, your eye doctor can see the clues. The signs of hypertensive retinopathy may be observed during a dilated eye exam using an ophthalmoscope, a lighted instrument that illuminates the structures in the eye. During this type of exam, the ophthalmologist can see the optic nerve, the retina and its center (the macula), and the blood vessels throughout the back of the eye. Hypertensive retinopathy may present as swelling in the macula, narrowing of the blood vessels, or micro-leaks from blood vessels.

Treat the Cause, Not the Symptoms

The way that hypertensive retinopathy is ideally treated is through proper medical management which lowers blood pressure. Once the retina has been extensively damaged, there may be no way to restore optimal vision.

Vitreo Retinal Surgery has several offices in Minnesota to assist you. Call (800) VRS-2500 for more information on retinopathy and potential treatment options to manage eye health.

The Importance of Knowing about Diabetic Eye Disease

November is Diabetic Eye Disease Month. Here, we discuss the risks that diabetic patients face and how long-term vision can be protected with a few simple steps.

Diabetes is a chronic health condition that has the potential to create a number of secondary problems in the body. As we have learned through years of research and practical experience, the eyes are particularly susceptible to the effects of unregulated blood sugar. In fact, studies show that the longer a person lives with diabetes, the greater their risk for diabetic retinopathy, a diabetic eye disease that could severely degrade vision.

How Diabetic Eye Disease Can Cause Vision Loss

Diabetic retinopathy is a condition in which the blood vessels at the back of the eye sustain damage. This can lead to:

  • Fluid accumulation around the retina and also in the vitreous cavity in front of the retina. This accumulation originates with weak, leaky blood vessels in this part of the eye. Initially, retinopathy does not show signs. Over time, weakness of one or more blood vessels can lead to a vitreous hemorrhage. Symptoms of this condition include blurry vision and floaters.
  • Macular edema. Swelling and fluid retention on the macula, the central part of the retina, may occur if diabetic retinopathy is not properly treated early on in its progression. As the macula swells, it may thicken, causing vision to become distorted.

In addition to diabetic retinopathy, statistics indicate that diabetes also increases the risk of vision-disrupting conditions like glaucoma and cataracts. Diabetic patients are at least twice as likely to develop one or both of these complications.

Vision Minneapolis MN

Protecting Your Vision

The primary problem with diabetic eye disease is that symptoms do not typically manifest right away. Because the key to successful eye health is to commence with a management program during the early stages of diabetic eye disease, awareness is vital to protecting vision. Patients are encouraged to:

Get Help with Blood Sugar Management

We know from clinical studies that blood sugar regulation is directly related to the onset of diabetic eye disease. Therefore, diabetes management is critical to the prevention of retinopathy and other conditions that may cause vision loss. Additionally, some studies suggest that keeping cholesterol levels lower further increases one’s resistance to diabetic eye disease. Blood sugar management can come from a partnership with a doctor or nutritionist and can be highly successful when maintained on a regular basis.

Get Annual Dilated Eye Exams

Patients who have been diagnosed with diabetes have a lot to gain by quickly scheduling a dilated eye exam. These exams are more comprehensive, allowing the ophthalmologist to observe the optic nerve, retina, blood vessels, and other important structures in the eye. A dilated eye exam would ideally be the first place for diabetic eye disease to be detected. This paves the way for prompt and appropriate treatment.

Vitreo Retinal Surgery proudly serves patients throughout Minnesota, including St. Paul, Minneapolis, and more. Schedule your diabetic eye exam with an experienced retinal specialist by calling 800-VRS-2500.

Diabetic Macular Edema: What is it and What can be Done to Preserve Sight?

Floaters and blurry vision are relatively common experiences for most adults. Double-vision? Not so much. If these are visual disturbances that regularly appear in your field of vision, we encourage you to schedule a visit with a board-certified ophthalmologist sooner rather than later. These phenomena are potential indications of diabetes. If not properly diagnosed and treated, floaters, double-vision and blurriness could ultimately result in vision loss. Here, we discuss how these symptoms are related to diabetic macular edema (DME) and what we can do to help you preserve your eyesight.

Diabetic macular edema is a serious eye condition characterized by excess fluid accumulation in the macula. This is the part of the eye in which the most detailed vision capabilities are controlled. Fluid accumulates here when blood vessels in the eye leak. Diabetic macular edema is a complication of diabetic retinopathy, the primary condition that causes leakage from these blood vessels. When DME develops, it may do so in one of two forms:

  • Focal DME results from abnormalities in the blood vessels of the eye.
  • Diffuse DME results from swelling of the capillaries in the retina.

Diabetics whose blood sugar is not well-regulated are at risk of diabetic retinopathy and the complication of diabetic macular edema. Additional associated risks include:

  • An extended period of time with diabetes
  • Fluid retention
  • Severe high blood pressure
  • Hyperlipidemia (high-fat levels in the blood)
  • Hypoalbuminemia (low protein levels in the blood)

How an Ophthalmologist can Help

It is necessary for people with symptoms of diabetic eye disease to obtain regular eye exams. This enables physicians to stay ahead of complications of the chronic blood-sugar disease. If a patient presents with symptoms of diabetic macular edema, we work quickly and often alongside the person’s primary healthcare team to reduce pressure in the eye and stop the capillary bleeding.

Both focal and diffuse DME may be treated with laser eye surgery, though the technique for each differs slightly. Focal DME may be treated with a focal laser, whereas diffuse DME may be treated with a grid laser to cover a wider operative area.

Causes of Retinal Detachment

The retina is a structure that sits at the back of the eye. The layers of cells that make up the retina are ultra-thin and sensitive to light. This light sensitivity is what allows the retina to record the various wavelengths that enter the eye and use the optic nerve to send electrical signals to the brain. The signals transmitted through the optic nerve are translated into visual images. This is the process of sight. It is a process that directly involves the retina and one that indicates just how crucial it is to keep this part of the eye healthy and functional.

Retinal detachment is a relatively rare event that occurs when the retinal membrane loosens from its foundation on the back of the eye. Here, we discuss the symptoms, causes, and contributing factors of a detached retina.

Symptoms of Retinal Detachment

Contrary to what one may expect, a detached retina is not a painful event. Because there is no discomfort to warn of detachment, it is vital to recognize other symptoms. As the retina comes loose from the back of the eye, flashes of light, floaters, specks, and spots may suddenly appear in the field of vision. Shadowing and blurriness may also occur. Any one of these symptoms warrants prompt medical attention.

Retinal Detachment Causes

Cases of retinal detachment usually result from one of three common underlying problems.

  • Tractional detachment occurs when scar tissue on the retinal surface creates a pulling effect that loosens the retina from the wall of the eye.
  • Exudative detachment is a condition in which the retina itself is in good condition, but fluid has built up beneath it as a result of inflammation or injury.
  • Rhegmatogenous detachment occurs when fluid builds up beneath the retina due to a hole or tear in its structure.

Contributing Factors in Retinal Detachment

There are no telltale indicators that any person will suffer retinal detachment. However, specific contributing factors have been noted for increasing risk. When more than one contributing factor is present, routine retinal evaluation becomes even more critical to long-term health and wellness. People with more than one of the following may also want to have a plan in place to obtain prompt emergency services from a retinal specialist.

  • Over 50 years of age.
  • A family history of retinal detachment.
  • Previous retinal detachment.
  • Previous eye surgery.
  • Severe eye or head injury.
  • Advanced diabetes.
  • Extreme nearsightedness.

What to Do About Retinal Detachment

A detached retina can be repaired so long as it remains somewhat intact. This is why immediate medical care is necessary in the event of sudden-onset symptoms. If the retina detaches completely, the thin tissue becomes non-viable and permanent blindness will occur in that eye.
