Retinal Disease Screening in Brooklyn: Why Early Detection Saves Your Vision
Retinal diseases like diabetic retinopathy and age-related macular degeneration often develop silently—you won't notice symptoms until significant damage has occurred. A proper retinal screening catches these conditions in their early stages when treatment can actually preserve your sight.
At Nostrand Optical in Crown Heights, Dr. Shlivko performs comprehensive retinal screenings as part of every eye exam. If you have diabetes, are over 50, or have a family history of retinal disease, this screening is critical.
Key Takeaways
- Retinal diseases like diabetic retinopathy and macular degeneration usually have no early warning signs—screening is your only defense
- A dilated eye exam combined with imaging technology lets Dr. Shlivko spot retinal problems before they cause vision loss
- Diabetic patients should have annual retinal screenings; patients over 50 benefit from screenings every 1-2 years
- Early treatment can slow or stop progression of most retinal diseases
- We accept Medicaid and Medicare—cost shouldn't prevent you from getting screened
What Is a Retinal Screening and Why Does It Matter?
Your retina is the light-sensitive tissue at the back of your eye that sends visual signals to your brain. When the retina is damaged, your vision deteriorates—sometimes dramatically. The problem is that retinal disease often progresses without any noticeable symptoms in the early stages.
By the time you notice blurred vision or floaters, significant damage may have already happened. That's why retinal screening isn't optional if you're at risk. It's the only way to catch trouble early enough to actually do something about it.
A comprehensive retinal screening involves:
- Dilating your pupils so Dr. Shlivko can see the entire retina clearly
- Direct examination using a specialized lens and microscope
- Retinal imaging (fundus photography or OCT scanning) to document any changes over time
- Discussion of findings and next steps if anything abnormal is detected
The whole process takes about 30 minutes and is painless. Your pupils will stay dilated for a few hours afterward, so plan to wear sunglasses when you leave.
If you're overdue for an eye exam, don't wait. Book your retinal screening with Dr. Shlivko at Nostrand Optical—we're right here on Nostrand Ave in Crown Heights and accept Medicaid and Medicare.
Diabetic Retinopathy: The Silent Vision Thief
Diabetic retinopathy is the leading cause of vision loss in working-age adults. It happens when high blood sugar damages the tiny blood vessels in your retina. The damage progresses through stages:
Early (nonproliferative) diabetic retinopathy: Small bulges appear in retinal blood vessels, sometimes leaking fluid or blood. You won't feel it happening. Your vision may seem fine.
Advanced (proliferative) diabetic retinopathy: The retina becomes oxygen-deprived, triggering growth of abnormal new blood vessels. These are fragile and bleed easily, causing sudden vision loss.
The critical fact: diabetic retinopathy is preventable and treatable if caught early. If you let it progress to the bleeding stage, vision loss can be permanent.
Who needs screening: Every person with diabetes—whether Type 1 or Type 2, whether your blood sugar feels "controlled" or not. The American Optometric Association recommends annual dilated eye exams for all diabetic patients.
What Dr. Shlivko looks for: Any signs of vessel damage, leakage, or abnormal growth. Early-stage disease may not need treatment beyond better blood sugar control. But if Dr. Shlivko spots signs of progression, you'll get a referral to a retinal specialist for laser treatment or injection therapy, which can stop the disease in its tracks.
Why it matters in Crown Heights: We see a lot of families managing diabetes. Too often, patients skip eye exams because they're focused on managing blood sugar or because they don't understand the risk. Retinal screening isn't a luxury—it's part of diabetes care.
If you have diabetes and haven't had an eye exam in the last year, schedule your screening with us. Medicaid and Medicare both cover annual diabetic retinopathy screenings.
Age-Related Macular Degeneration: The Aging Eye's Challenge
Age-related macular degeneration (AMD) affects the macula—the part of your retina responsible for sharp, central vision. It's the leading cause of vision loss in people over 50. And it's becoming more common as our population ages.
There are two main types:
Dry AMD: The retina's light-sensitive cells gradually break down. Vision loss is slow but progressive. About 80% of people with AMD have the dry form. There's no cure, but certain vitamins and lifestyle changes can slow progression.
Wet AMD: Abnormal blood vessels grow under the retina and leak fluid, causing rapid vision loss. It's less common but more serious. The good news: if caught early, medications (anti-VEGF injections) can stop or slow the bleeding.
Early warning signs you might notice:
- Straight lines (like the edge of a door) appear wavy
- A blurry or dark spot in the center of your vision
- Colors seem less vibrant
- Difficulty reading or recognizing faces
The catch: Many people don't notice these signs until AMD is already advanced. That's why screening matters.
Who's at risk: Anyone over 50, especially if you:
- Smoke or used to smoke
- Have a family history of AMD
- Have high blood pressure or high cholesterol
- Are Caucasian (AMD is more common in white populations)
What Dr. Shlivko looks for: Early changes in the macula like drusen (yellow deposits) or areas of retinal thinning. He may recommend additional imaging (OCT scans) to measure retinal thickness and spot wet AMD before you notice symptoms.
Real example: A 58-year-old patient from Prospect Heights came in for glasses. During the retinal screening, Dr. Shlivko noticed early signs of dry AMD—nothing the patient had felt. He explained the findings, recommended specific vitamins (lutein and zeaxanthin), and scheduled a follow-up in six months. Annual screenings now monitor whether it's progressing. Because it was caught early, we have time to slow it down. Without that screening, the patient might have woken up five years later with sudden vision loss.
That's the difference screening makes.
Other Retinal Diseases That Screening Can Catch
Diabetic retinopathy and AMD account for most retinal disease, but Dr. Shlivko screens for several other serious conditions:
Retinal detachment: The retina separates from the back of the eye. It's an emergency. Early warning signs are new floaters or flashes of light. If you notice these symptoms, contact us immediately. During routine screening, we catch early, asymptomatic detachments before they cause vision loss.
Retinal tears: Small rips in the retina that can lead to detachment if untreated. Screening catches them so we can prevent progression.
Branch or central retinal artery occlusion: A blood clot blocks blood flow to part of the retina, causing sudden vision loss. Screening can reveal previous occlusions and assess your stroke and heart attack risk.
Hypertensive retinopathy: High blood pressure damages retinal blood vessels. Screening shows us how aggressively we need to manage your hypertension.
Retinal vein occlusion: Similar to artery blockage but affects veins. Can cause swelling and vision loss.
Optic nerve damage: Though technically not retinal disease, we evaluate the optic nerve during retinal screening. Changes can indicate glaucoma, which requires aggressive treatment.
Each of these conditions needs early detection to preserve vision. A comprehensive retinal screening—which you get with every eye exam at Nostrand Optical—evaluates all of them.
How Retinal Screening Works: What to Expect
When you come in for a retinal screening at Nostrand Optical, here's what happens:
Step 1: Eye history and risk assessment (5 minutes) Dr. Shlivko asks about diabetes, family history of retinal disease, vision changes, and medications. This context matters—it tells him what to look for.
Step 2: Visual acuity and eye pressure (5 minutes) Standard tests that are part of every eye exam.
Step 3: Dilation (5 minutes) Numbing drops, then dilating drops go in your eyes. These expand your pupils so Dr. Shlivko can see the entire retina. Your vision will be blurry and you'll be sensitive to light for a few hours.
Step 4: Dilated examination (10-15 minutes) Dr. Shlivko uses a specialized lens and microscope to examine your retina thoroughly. He's looking at blood vessels, the macula, the optic nerve, and the outer edges of the retina. This is the heart of the screening.
Step 5: Imaging (5-10 minutes, if indicated) If anything looks abnormal, Dr. Shlivko may use OCT (optical coherence tomography) or fundus photography to get detailed images. These create a digital record so we can track changes over time.
Step 6: Discussion and next steps (5-10 minutes) Dr. Shlivko explains his findings in plain language. If your retina is healthy, he'll tell you when to come back (usually annually if you have diabetes, every 1-2 years otherwise). If something needs attention, he explains your options and may refer you to a retinal specialist.
Total time: About 45 minutes.
Cost: Your eye exam (which includes retinal screening) is covered by Medicaid and Medicare. If you have commercial insurance, we'll verify your coverage beforehand. Check your insurance coverage at our website.
Who Needs Retinal Screening and How Often?
Not everyone needs annual retinal screening. The frequency depends on your risk factors.
Annual screening is recommended if you have:
- Type 1 or Type 2 diabetes (no exceptions)
- Age 50 and older
- Family history of retinal disease
- High blood pressure
- High cholesterol
- History of eye surgery or injury
Every 1-2 years if you have:
- Age 40-49 with no risk factors
- Mild or no risk factors overall but want preventive care
As part of routine care if you:
- Are under 40 with no risk factors
- Still benefit from screening—it's included in your comprehensive exam
The reality in Crown Heights is that many patients skip eye exams altogether because they think their vision is fine or they're worried about cost. That's exactly backwards. You feel fine because retinal disease doesn't hurt. And cost shouldn't stop you—Medicaid and Medicare both cover comprehensive exams including retinal screening.
If you're unsure whether you need screening, call our office or book an appointment. Dr. Shlivko will evaluate your risk and recommend the right schedule for you.
Early Detection and Treatment: What Happens When We Find Something
Let's say Dr. Shlivko spots early diabetic retinopathy during your screening. What's next?
First, he'll explain what he sees. Not scary medical jargon—clear language about what the findings mean for your vision.
If it's early nonproliferative diabetic retinopathy (small vessel damage, no bleeding):
- The focus is blood sugar control. Better glucose management can slow or stop progression.
- You may not need any eye treatment yet, but close monitoring is critical.
- Dr. Shlivko schedules a follow-up exam in 3-4 months to see if it's stable.
- You might benefit from a referral to your primary care doctor or endocrinologist to optimize your diabetes management.
If it's progressing or reaching the proliferative stage (abnormal vessel growth):
- Dr. Shlivko refers you to a retinal specialist who can perform laser treatment or anti-VEGF injections.
- These treatments work best when caught early—before major bleeding or vision loss.
- We stay in touch with the specialist to coordinate your care.
If it's early dry AMD (drusen, no vision loss):
- We may recommend supplements (Bausch + Lomb PreserVision or similar formulas with lutein, zeaxanthin, vitamins C and E, zinc).
- Smoking cessation if you smoke—this single step slows AMD progression more than anything else.
- Regular monitoring every 6-12 months to catch any shift to wet AMD.
If it's wet AMD (bleeding under the retina):
- This is urgent. Dr. Shlivko refers you to a retinal specialist immediately.
- Anti-VEGF injections (Avastin, Lucentis, Eylea) are injected directly into the eye to stop abnormal vessel growth and bleeding.
- These work best when started quickly—sometimes within days of detection.
The bottom line: early detection + prompt treatment = vision saved. Delayed detection = permanent vision loss.
Patient story: María, 54, has had Type 2 diabetes for eight years. She'd been skipping eye exams because her vision felt fine and she was tired of doctor appointments. After her grandson's school recommended a comprehensive exam for all family members, she came to Nostrand Optical. During retinal screening, Dr. Shlivko spotted mild nonproliferative diabetic retinopathy—vessel damage but no bleeding yet. He explained the findings and referred her back to her primary care doctor with a note about the retinal changes. Her doctor adjusted her medications. Dr. Shlivko saw her again three months later. The retinal changes had stabilized. Now she comes annually for screening. Because we caught it early, her vision is preserved, and her diabetes management has actually improved. She's also talking to other family members in Crown Heights about getting their eyes checked.
Beyond the Screening: Living With Retinal Disease
If Dr. Shlivko detects retinal disease, you're not on your own. We coordinate your care with retinal specialists, your primary care doctor, and your endocrinologist (if you have diabetes).
Between appointments, you can:
- Monitor your own vision using an Amsler grid (especially important if you have AMD). We can show you how.
- Track your blood sugar if you're diabetic.
- Control blood pressure and cholesterol.
- Avoid smoking—it accelerates retinal disease.
- Protect your eyes from UV light (wear sunglasses outside).
- Eat a retina-healthy diet: leafy greens, fatty fish, eggs, nuts, citrus fruits.
Warning signs that need immediate attention:
- Sudden floaters or flashes of light
- New dark spot in your central vision
- Lines that should be straight appearing wavy
- Sudden blur or vision loss in one eye
If you notice any of these, call immediately. Don't wait for your next appointment.

Conclusion: Your Retina Deserves Annual Screening
Retinal disease is silent, progressive, and treatable—but only if caught early. Once vision is lost to diabetic retinopathy or macular degeneration, it often can't be fully restored.
Annual retinal screening is one of the most powerful tools we have to preserve your sight. If you have diabetes, are over 50, or have a family history of retinal disease, there's no good reason to skip it.
Dr. Shlivko performs comprehensive retinal screenings as part of every eye exam at Nostrand Optical. We accept Medicaid and Medicare. Same-day glasses are available if you need an updated prescription. And you'll be seen by the same doctor every time—not a rotating chain-store staff.
Your vision is too important to leave to chance. Schedule your retinal screening with Dr. Shlivko today. We're at 1018C Nostrand Ave in Crown Heights, and we're accepting new patients.
