Macular Degeneration

Macular degeneration is a common retinal condition that affects the macula, the part of your eye responsible for sharp, central vision. It tends to show up later in life, which is why it’s often called age-related macular degeneration, or AMD.

You might not notice it right away. A slight blur in your reading vision. Faces starting to look less clear. Straight lines that seem just a little off. Over time, those subtle shifts can become more disruptive, especially if left untreated.

There are two main types, dry AMD, which develops slowly, and wet AMD, which can progress more quickly due to abnormal blood vessel growth under the retina. While there’s currently no cure, many treatments can slow its progression and preserve your vision longer.

If you’ve been told you have AMD, or if you’re just concerned about changes in your sight, we’re here to guide you through it, every step of the way.

Diabetic Retinopathy

Diabetic retinopathy is a condition where high blood sugar levels gradually damage the tiny blood vessels in the retina, the light-sensitive layer at the back of your eye. Over time, those vessels can leak, swell, or close off entirely, leading to vision changes that may not be obvious at first.

Some people notice blurry or fluctuating vision. Others might see dark spots or difficulty focusing. And in more advanced stages, new, fragile blood vessels may grow where they shouldn’t, increasing the risk of serious complications like bleeding or retinal detachment.

But here’s the hopeful part: with regular monitoring and timely treatment, vision loss from diabetic retinopathy can often be prevented or slowed.

If you’re living with diabetes, your eyes need just as much attention as your blood sugar. Routine retinal exams are essential, even if your vision still feels fine. We’re here to help you stay ahead of the condition and protect your sight for the long term.

Retinal Tears & Retinal Detachment

The retina is a delicate, light-sensitive layer that lines the back of your eye, sort of like film in a camera. If it tears or detaches, your vision can be at serious risk. These conditions often come on suddenly, and the sooner they’re treated, the better the chances of preserving your sight.

A retinal tear happens when the thin tissue of the retina develops a rip, often due to the natural shrinking of the gel-like vitreous inside the eye. It might not hurt, but you could notice sudden flashes of light, new floaters, or a shadow creeping into your peripheral vision. Prompt treatment, usually with laser or cryotherapy, can often seal the tear before it progresses.
Learn more about Retinal Tears

If fluid slips through a tear and gets underneath the retina, it can lift or "detach" the retina from the back of the eye, much like wallpaper peeling off a wall. This is a medical emergency. Symptoms can include a sudden drop in vision, a dark curtain over part of your sight, or a rapid increase in floaters and flashes. Surgery is typically needed to repair the detachment and save your vision.
Learn more about Retinal Detachment

Macular Hole & Macular Pucker

The macula, located at the center of your retina, is what allows you to see fine details, whether you’re reading, recognizing faces, or enjoying a beautiful view. But when the surface of the macula is damaged or stressed, it can affect the clarity and sharpness of what you see straight ahead. Two common causes of this are macular holes and macular puckers.

A macular hole is exactly what it sounds like, a small break in the central retina. It often develops gradually, starting with blurred or distorted vision. Over time, you might notice a dark or missing spot right in the center of what you’re looking at. These holes can result from age-related changes or an injury, and surgery (called vitrectomy) is typically recommended to close the hole and help restore some of the lost vision.
Learn more about Macular Hole

A macular pucker happens when a thin layer of scar tissue forms over the macula, causing it to wrinkle or contract slightly. This can lead to vision that’s wavy or mildly blurry, like looking through a piece of crinkled plastic. Many cases are mild and don’t need immediate treatment, but if the distortion becomes significant, surgery can be considered to smooth out the macula.
Learn more about Macular Pucker

Retinal Vascular Occlusions

Your retina is a living layer of tissue that depends on healthy circulation to function—much like the heart or brain. When a blood vessel in the retina becomes blocked, whether by a clot or narrowing, the normal flow of oxygen and nutrients is disrupted. This can cause vision to blur, darken, or disappear altogether, sometimes suddenly, sometimes gradually.

Retinal vascular occlusions are grouped into two main types: vein occlusions (where blood backs up in the eye) and artery occlusions (where blood supply is cut off). Both require urgent attention, but their causes, symptoms, and treatments can differ.

BRVO occurs when one of the smaller branches of the main retinal vein becomes blocked. This often results in blurry or distorted vision in one portion of your visual field, typically from swelling (macular edema) or small retinal hemorrhages. High blood pressure and diabetes are common underlying factors. With prompt treatment—usually eye injections to reduce swelling—vision can often be stabilized or even improved.
Learn more about Branch Retinal Vein Occlusion →

CRVO is a more extensive blockage of the retina’s main drainage vein. It can lead to widespread vision loss, swelling in the central retina, and sometimes the growth of abnormal new blood vessels. Treatment may involve anti-VEGF injections or laser therapy, depending on the severity. Early diagnosis is key to preserving as much sight as possible.
Learn more about Central Retinal Vein Occlusion →

Retinal artery occlusions happen when blood flow into the retina is suddenly blocked, often by a clot or plaque. Central Retinal Artery Occlusion (CRAO) affects the main artery and typically causes sudden, painless, severe vision loss in one eye, considered a true medical emergency. Branch Retinal Artery Occlusion (BRAO) impacts a smaller vessel and causes partial vision loss. These events are often linked to underlying cardiovascular issues, so immediate evaluation is critical, not just for your eyes, but for your overall health.
Learn more about Retinal Artery Occlusions

Macular Disorders

The macula is the small, hardworking center of your retina, responsible for the sharp, central vision you use every day. Reading fine print, recognizing a loved one’s face, even threading a needle, these things rely on a healthy macula.

But when something goes wrong here, even simple tasks can start to feel strangely difficult. Lines may look wavy. Words might blur. Colors could seem duller than you remember.

In MacTel, delicate blood vessels in the macula become abnormal—leaky or widened—causing distortion or blurriness in your central vision. It often starts subtly, with reading becoming harder or noticing straight lines seem slightly bent.
Learn more about Macular Telangiectasia (MacTel)

This condition typically affects younger to middle-aged adults, often during times of stress. A small pocket of fluid builds up under the retina, which can cause a gray or blurry spot right in the middle of your vision. Sometimes it clears on its own, but not always.
Learn more about Central Serous Chorioretinopathy

RP is usually inherited and first shows up as trouble seeing at night or losing side vision. Over time, though, it can affect the macula too, making sharp, central vision harder to maintain. It’s a slower progression, but it's important to monitor.
Learn more about Retinitis Pigmentosa (RP)

When Should You Visit A Retina Specialist?

Not every eye issue needs a retina specialist, but when it does, it’s important not to wait. The retina plays a central role in how you see the world, and when something goes wrong there, early treatment can make all the difference.

So how do you know when it’s time to see a retina specialist?

If you’ve been diagnosed with a condition like macular degeneration, diabetic retinopathy, retinal tears, detachment, or vascular occlusions, your eye doctor may refer you directly. But even without a diagnosis, there are symptoms that should never be ignored.

Here are some signs it’s time to get checked by our retina specialists:
  • Sudden loss or distortion of vision in one eye
  • Flashes of light at the edge of your vision
  • A sudden surge in floaters—specks or cobweb‑like shapes drifting across your sight
  • A dark curtain or shadow sweeping over part of your field of view
  • Straight lines that appear wavy or letters that seem to vanish
  • Gradual narrowing of side (peripheral) vision or “tunnel” vision
  • Newly blurred or wavy central vision
  • Any vision change if you live with diabetes, high blood pressure, severe nearsightedness, or have recently had a stroke
  • High‑risk but symptom‑free?Long‑standing diabetes, high myopia, prior eye surgery/trauma, or a strong family history of retinal disease all warrant regular retina check‑ups, even when your sight feels normal.
Our job as retina specialists is to uncover what’s happening beneath the surface, explain it in clear terms, and guide you to the safest, most effective treatment. Whether you were referred or you’re simply concerned, we’re here to protect what matters most, your sight.
