Retinal Diseases

Your retina is located at the back of your eye. It is a thin, light-sensitive tissue that controls how you see images by sending electrical impulses to the brain via the optic nerve. Many of us take a healthy retina for granted. However, if there is any damage to this part of your eye due to aging, trauma, injury, smoking, diseases, etc., you may start to experience vision problems.

There are many different types of retinal diseases and conditions that can affect the retina including:

• Diabetic Retinopathy
• Macular Degeneration
• Macular Hole/Pucker
• Retinal Detachment
• Glaucoma

Read on to learn more about each of these diseases/conditions. Our team diagnoses retinal diseases in Bismarck, ND, and offers advanced treatments.

Diabetic Retinopathy

Diabetic retinopathy is a common condition that can affect both eyes. It’s caused by damaged retinal blood vessels in people with diabetes. If you have uncontrolled blood sugar levels, you’re at risk of developing diabetic retinopathy. Often, those with the condition have mild vision problems but can potentially lose their eyesight if left untreated.

Symptoms of Diabetic Retinopathy

Unfortunately, the signs of diabetic retinopathy usually don’t appear until damage to the eye has already occurred. Some symptoms of the disease include:

• Having trouble seeing at night
• The appearance of floaters
• Blurry vision
• Difficulty differentiating colors
• Vision loss

You can avoid irreversible damage to your sight by scheduling routine eye exams, which can help detect the condition early. You should also keep your blood sugar levels under control.

Macular Degeneration

At the center of the retina is the macula. The macula is where detailed and central vision occurs. Age-related macular degeneration (AMD) is an eye condition that impacts the macula. AMD occurs in people who are 50 and older and can affect one or both eyes. Those with macular degeneration don’t go completely blind. Their peripheral vision remains intact. But due to AMD, people can’t read fine details, drive, or see faces. Typically, AMD presents no symptoms in the early stages.

AMD Symptoms

Age-related macular degeneration has various signs and symptoms. They are:

• Blind spots
• Slightly blurry vision
• Straight lines appearing wavy

Early detection of AMD is key to preserving your functional vision. While there’s no cure for age-related macular degeneration, treatment can slow the disease and prevent severe vision loss.

Macular Hole/Pucker

A macular pucker is a thin layer of scar tissue that forms on top of the retina. The amount of scar tissue can range from mild to severe. Mild macular puckers may be barely noticeable during an eye exam and resemble a fine layer of cellophane resting on the macula. More severe macular puckers can cause wrinkling or distortion of the macula. In contrast to a macular pucker, a macular hole is a small gap that extends through the entire thickness of the macula.

Macular Hole/Pucker Symptoms:

• Mild blurring of central vision
• Wavy or distorted vision
• A central blind spot
• Straight lines appearing broken or having a piece missing in the middle

Treatment will range, depending on the severity of the condition, from close monitoring to surgery. Surgery by a retina specialist usually leads to significant restoration of vision.

Retinal Detachment

Retinal detachment is an urgent situation where a thin layer of tissue (the retina) pulls away from its normal position. The longer a retinal detachment goes untreated, the greater the risk of permanent vision loss in the affected eye.

Warning Signs of Retinal Detachment

• Sudden appearance of floaters: small dark spots or squiggly lines that seem to drift through the field of vision
• Flashes of light in one eye
• A curtain-like shadow over the field of vision

The symptoms of retinal detachment often appear rather suddenly. If a retinal detachment is not treated right away, more of the retina can detach, which increases the risk of permanent vision loss or blindness.

Treatment for Retinal Detachment

The type of treatment or surgery your doctor suggests will depend on how much of the retina is detached and what type of retinal detachment you have. Treatment for retinal detachment in Bismarck, ND, typically works well if the detachment is caught early.

Glaucoma

Glaucoma is a group of eye diseases resulting in optic nerve damage due to increased intraocular pressure (IOP). There are many reasons why pressure in the eye increases. In some instances, it’s due to inflammatory conditions, injury, genetics or infection. Glaucoma can also stem from your eye losing its ability to drain fluid. This is because the eyes constantly produce a clear fluid called aqueous humor. Aqueous humor maintains the shape of your eye and keeps your eyes nourished. Once this fluid makes its way into the eye, it must drain out through the drainage angle.

Damage to the drainage angle creates an imbalance in your eye. The eye’s rate of producing the aqueous humor becomes greater than the rate at which the aqueous humor can be drained. With this combination, high intraocular pressure occurs.

Glaucoma and Retinal Disease

The retina has neurons called ganglion cells responsible for sending visual information to the brain. An increase in pressure inside your eye destroys the ganglion cells, resulting in vision problems like glaucoma. Glaucoma has no cure and vision loss due to the condition is irreversible. Further progression can be stopped or slowed down with early detection and treatment.
