How Often Should Diabetics Get an Eye Exam?

Alex Mannine | 2026-08-21 | Category: Metabolic Health

ADA guidance generally recommends that most adults with type 2 diabetes have a comprehensive dilated eye exam at or shortly after diagnosis, and that most adults with type 1 diabetes have their first exam within five years of diagnosis onset. After that, follow-up is often at least annual, though every one to two years may be considered following one or more normal exams when glucose indicators are within goal—and more frequent exams are appropriate whenever retinopathy or other risk factors are present. Timing is always shaped by individual history, pregnancy, kidney disease, symptoms, access, and clinician judgment.

Key takeaways

ADA guidance generally recommends an initial comprehensive dilated exam at or near diagnosis for type 2 and within five years of onset for type 1; the exact schedule is decided with a care team, not by a general rule alone.

Annual follow-up is a common starting point, but a one-to-two-year interval may be considered after one or more normal exams with glucose indicators within goal—and shorter intervals are standard when retinopathy or other concerns are present.

People who are pregnant and have preexisting diabetes generally need eye care before conception or in the first trimester, with follow-up frequency determined by the eye care team throughout pregnancy and postpartum.

Sudden vision changes, new floaters, flashes, or a curtain-like shadow are urgent symptoms that warrant same-day or emergency eye care—do not wait for a scheduled appointment.

Short Answer: How Often Should Diabetics Get an Eye Exam?

ADA guidance generally recommends a comprehensive dilated eye exam at or near type 2 diagnosis and within five years of type 1 onset. Annual follow-up is a common benchmark, though every one to two years may be appropriate after consistently normal findings with glucose on target. Retinopathy, pregnancy, new symptoms, or other risk factors generally call for more frequent evaluation—always guided by a clinician.

Why Eye Exam Scheduling Is Different for People With Diabetes

Most people without diabetes get a routine eye exam every one or two years. For someone living with diabetes, the stakes and the recommended timing are meaningfully different. Diabetic eye disease—primarily diabetic retinopathy and diabetic macular edema—can progress silently, producing no noticeable symptoms until it has reached an advanced stage.

To understand why these conditions develop silently, see our companion article How Does Diabetes Affect the Eyes?, which covers the underlying disease mechanisms in detail. This article focuses specifically on screening frequency: when to schedule exams, what affects that timeline, and how to navigate the process.

The short version is that a dilated or comprehensive exam allows an eye care provider to look directly at the retina—the light-sensitive tissue at the back of the eye—and spot early changes in blood vessels before vision is noticeably affected. The American Diabetes Association (ADA) Standards of Care provide structured guidance on when those exams should happen, and the National Eye Institute (NEI) and National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) echo that message across their public resources.

What Does "ADA Guidance Generally Recommends" Actually Mean?

Throughout this article you will see language like "ADA guidance generally recommends." That phrasing is intentional. The ADA's Standards of Care are updated annually and reflect the best available evidence, but they are written as population-level guidance, not individual prescriptions. Your actual schedule depends on:

Diabetes type — Type 1 and type 2 have different initial exam timing.
Duration of diabetes — The longer someone has lived with diabetes, the greater the cumulative exposure.
Prior eye exam findings — One or more normal exams may support a longer interval; any retinopathy generally shortens it.
Glucose indicators — Whether A1C and related markers are within an individually agreed goal influences monitoring frequency.
Pregnancy — Preexisting diabetes combined with pregnancy requires a specific eye care plan that the eye care team and obstetric team coordinate.
Kidney disease — Diabetic kidney disease and diabetic eye disease often travel together; a care team may coordinate their monitoring closely.
Symptoms — New or worsening symptoms always override a general schedule.
Access and coverage — Insurance, geography, and provider availability are real factors your team can help navigate.
Clinician judgment — Your ophthalmologist or optometrist may see findings that change your plan immediately.

This is why the ADA guidance describes benchmarks rather than universal mandates. The right schedule is the one your care team designs for your situation.

Initial Exam Timing: Type 2 vs. Type 1

Type 2 Diabetes

ADA guidance generally recommends that people with type 2 diabetes have a comprehensive dilated eye exam at diagnosis or shortly thereafter. This recommendation exists because type 2 diabetes is often diagnosed years after it actually begins, meaning retinopathy may already be present at the time of a first diagnosis. An eye exam at or near that point establishes a baseline and catches any early findings before they progress.

Type 1 Diabetes

For people with type 1 diabetes, ADA guidance generally recommends the first comprehensive dilated eye exam within five years of the onset of diabetes. The timeline reflects evidence that clinically significant retinopathy is uncommon in the very early years of type 1, particularly in children and adolescents, but risk increases meaningfully after several years of exposure.

It is important to note that "onset" in type 1 refers to the beginning of the disease itself—not necessarily the date of diagnosis, though the two are often close in type 1. A clinician is best placed to interpret this in an individual case.

Follow-Up Cadence After the Initial Exam

Once the first exam is complete, frequency is calibrated to what was found—and to ongoing glucose management.

When No Retinopathy Is Found

If the initial exam shows no retinopathy and glucose-related indicators are within goal, ADA guidance notes that exams every one to two years may be reasonable. This is not a blanket permission to skip annual exams; it is a conditional option that a clinician evaluates based on the full picture. Many eye care providers and endocrinologists prefer to maintain annual visits as a default, particularly when there is any uncertainty about glucose stability.

When Retinopathy Is Present

When any degree of retinopathy is detected, exams generally become more frequent—not less. The exact interval depends on the severity and type of retinopathy. Mild non-proliferative diabetic retinopathy (NPDR) may be monitored more closely than a single normal exam, while more advanced stages—severe NPDR, proliferative diabetic retinopathy (PDR), or diabetic macular edema (DME)—typically warrant follow-up in weeks to months rather than a year. For information about what treatment and prognosis look like at those stages, see Is Diabetic Retinopathy Reversible?.

When Glucose Is Not Consistently Within Goal

Even with no retinopathy found on a prior exam, a period of significantly elevated glucose may prompt a clinician to schedule follow-up sooner. The relationship between long-term glucose exposure and retinopathy risk is well established in the literature, and care teams factor this into their monitoring plans.

A Cadence Reference Table

The table below summarizes general ADA-informed guidance by situation. This is an educational reference, not a personal prescription. Your care team determines the right interval for you based on your full history.

Situation	General ADA-Informed Guidance
Type 2 diabetes, newly diagnosed	Comprehensive dilated exam at or near diagnosis
Type 1 diabetes, within first 5 years	First comprehensive dilated exam generally within 5 years of onset
No retinopathy found, glucose within goal	Annual exam common; every 1–2 years may be considered after ≥1 normal exam
Any retinopathy detected	More frequent follow-up; exact interval determined by severity and clinician
Significant glucose fluctuation	Care team may shorten interval even with prior normal findings
Preexisting diabetes + pregnancy	Eye care before conception or in first trimester; follow-up throughout pregnancy and postpartum as determined by care team
Advanced retinopathy or macular edema	May need evaluation every few weeks to months; managed by specialist
New or worsening vision symptoms	Prompt/urgent evaluation—do not wait for next scheduled exam

Eye Exams During Pregnancy

People who have preexisting diabetes—type 1 or type 2—and are planning a pregnancy or become pregnant need a specific eye care conversation. ADA guidance generally recommends a comprehensive eye exam before conception if possible, or in the first trimester, and close follow-up through pregnancy and the year after delivery. This recommendation does not apply to gestational diabetes (diabetes that first appears during pregnancy), which is a different situation.

Why does pregnancy require special attention? Rapid changes in glucose management, blood pressure, and circulation during pregnancy can affect the retina. It is important to be clear about what guidance does and does not say: ADA guidance acknowledges that retinopathy may worsen during pregnancy in people with preexisting diabetes, but it does not say that pregnancy causes or guarantees progression. Whether and how quickly someone's retina changes during pregnancy varies by person and is something the eye care team tracks through the scheduled exam series.

If you are planning a pregnancy and have diabetes, bring this topic to your care team early so an eye exam can be scheduled as part of your preconception planning. The Diabetes Appointment Preparation Checklist can help you organize the questions you want to raise before or at a preconception visit.

Who Performs a Diabetic Eye Exam? Ophthalmologist vs. Optometrist

Many people with diabetes wonder whether they need an ophthalmologist (a medical doctor who specializes in eye health and can perform surgery) or whether an optometrist (a doctor of optometry who is licensed to examine eyes, prescribe corrective lenses, diagnose and treat certain eye conditions, and in many states prescribe some medications) is appropriate for their diabetic eye screening.

Both can perform a comprehensive dilated eye exam in most contexts, and both are trained to detect diabetic retinopathy. The key question is not the title but whether the provider is experienced with diabetic eye disease and can perform or refer you for a comprehensive dilated examination.

In practice:

Optometrists are often more accessible, may have shorter appointment wait times, and in many communities are the primary source of diabetic eye exams. Many are highly experienced in detecting and grading retinopathy and work within coordinated care networks.
Ophthalmologists are medical doctors (M.D. or D.O.) who can also manage retinal disease surgically or with injections. If retinopathy is found—or if significant disease is suspected—you may be referred to a retinal specialist (a subspecialist ophthalmologist) for further evaluation and management.

The most important step is to have the exam done. If you are unsure which type of provider to see, your primary care physician or diabetes care team can help direct you based on local availability and your specific situation. If you are told you need a dilated exam but your current provider does not perform one, ask for a referral.

What Happens During a Comprehensive Dilated Eye Exam?

Understanding what to expect can make the visit less intimidating and help you prepare the right questions.

Before the Exam

Dilating drops are placed in your eyes. These widen the pupil so the provider can see the full retina. The drops typically take 20–30 minutes to work, and your vision will be blurry and sensitive to light for several hours afterward. Plan for a driver or arrange a ride home. Bring sunglasses. If possible, schedule the exam on a day when blurry close-up vision won't be a problem for work or driving.

Bring your current glasses or contact lenses to the appointment. If you have a glasses prescription, bring it. The provider will want to know:

How long you have had diabetes and what type
Current medications, including any eye drops
Your most recent A1C and blood pressure readings (the Diabetes Appointment Preparation Checklist can help you organize these)
Any vision changes you have noticed

During the Exam

A comprehensive diabetic eye exam typically includes:

Visual acuity testing — the familiar letter chart to measure how clearly you see at different distances.
Tonometry — a measurement of eye pressure to screen for glaucoma, which occurs at higher rates in people with diabetes.
Dilated fundus examination — after the drops take effect, the provider uses a special lens and light to directly examine the optic nerve, macula, and peripheral retina for signs of retinopathy, swelling, abnormal blood vessels, or hemorrhages.
Slit-lamp examination — a high-powered microscope used to examine the front of the eye and the lens for cataracts, which also occur at higher rates in people with diabetes.

Retinal Imaging: A Note on Its Role

Some practices use retinal cameras (fundus photography) or optical coherence tomography (OCT) to create detailed images of the retina. These images can document findings over time, support grading decisions, and in some telehealth-based programs, allow remote review by an eye care provider. However, retinal imaging—including validated AI-assisted reading systems—does not universally replace a comprehensive dilated exam in current standard care. Imaging may support screening in settings with limited access to eye specialists, but whether imaging alone is sufficient for your situation is a clinical determination. Ask your provider what type of exam you are receiving and whether a dilated exam is included.

What Questions Should You Ask at a Diabetic Eye Exam?

Asking clear questions turns a routine exam into a useful dialogue. Consider bringing a written list. Some questions that may be useful:

"What did you find in today's exam, and how does it compare to my last visit?"
"Do I have any signs of retinopathy, and if so, how would you describe the stage?"
"What interval do you recommend before my next exam, and why?"
"Is there anything about my blood sugar or blood pressure that you'd like me to share with my diabetes care team?"
"Are there symptoms I should watch for between now and my next scheduled visit?"
"Is a dilated exam being performed, or is this an imaging-based screening?"
"If I am planning a pregnancy, what do you recommend for eye care before and during?"

Urgent and Emergency Eye Symptoms in Diabetes

A scheduled annual or biannual exam is not a substitute for addressing sudden changes. Some eye symptoms in people with diabetes require prompt or emergency evaluation—do not wait for a routine appointment.

Seek same-day or prompt professional evaluation for:

Sudden onset of new floaters (spots, strings, or cobwebs drifting in your vision)
Flashes of light in one or both eyes
A shadow, curtain, or veil appearing across part of your visual field
Sudden blurry vision in one eye that does not clear quickly
Significant distortion of straight lines or central vision

Seek emergency care if:

You experience sudden complete or near-complete loss of vision in one eye
Floaters appear suddenly with flashes and a large shadow or curtain (these together can indicate a retinal detachment or major bleed)

These symptoms can occur in anyone but are particularly important for people with diabetes because proliferative retinopathy creates fragile new blood vessels that can bleed unexpectedly. Early professional evaluation in these situations matters. The How Does Diabetes Affect the Eyes? article explains the underlying disease processes that create these risks in more detail.

How Eye Exam Cadence Connects to Your Broader Diabetes Screening Picture

Eye exams are one component of a broader diabetes monitoring picture that also includes kidney tests, foot evaluations, A1C, blood pressure, lipids, dental care, and vaccinations. There is no single universal annual checklist that applies to everyone—ADA guidance describes a range of assessments, each with its own timing logic, rather than a fixed once-a-year inventory.

It is also worth noting that eye and kidney disease in diabetes often share risk factors and can progress in parallel. Your care team may coordinate conversations about both. A general look at how diabetes affects multiple organ systems appears in How Does Diabetes Affect the Body?.

Frequently Asked Questions

Does everyone with diabetes need a dilated eye exam every single year without exception?

ADA guidance does not say "everyone must" have an exam every year without exception. Annual follow-up is a common benchmark, but every one to two years may be considered after one or more normal exams when glucose indicators are within an individually agreed goal. More frequent exams are standard when retinopathy or other risk factors are present, and timing always reflects clinician judgment and individual circumstances rather than a single rigid rule.

My last eye exam was normal. Can I wait longer than a year before my next one?

A normal result can support a longer interval in some situations—ADA guidance notes that every one to two years may be reasonable after consistently normal findings with glucose on target—but this is a decision made with your eye care provider and diabetes care team, not a self-determined choice. Factors such as glucose variability, any retinopathy at a prior exam, pregnancy, kidney disease, and new symptoms all influence whether your provider agrees that a longer interval is appropriate for you specifically.

What is the difference between a dilated eye exam and a regular eye exam for glasses?

A standard vision exam for glasses or contact lenses focuses on refractive error—how well you see—and may not include a full dilated examination of the retina. A comprehensive dilated eye exam uses drops to widen the pupil and allows the provider to directly examine the retina, optic nerve, and internal structures for disease. For diabetes screening purposes, a comprehensive dilated exam is what ADA guidance describes. If you are unsure whether your exam includes dilation, ask your provider before the appointment.

Can retinal photography or AI imaging replace my annual dilated exam?

Retinal imaging and AI-assisted reading programs are increasingly used in diabetes eye screening, particularly in settings with limited access to eye specialists, and some validated systems perform well for detecting retinopathy. However, imaging does not universally replace a comprehensive dilated exam in current standard care. Whether imaging alone is appropriate for your situation depends on the technology available, the setting, and your provider's clinical judgment. If you have questions about what type of exam you are receiving, ask your provider directly.

Do I need a separate eye exam if I already see an eye doctor for glasses?

Possibly, yes—it depends on what that exam includes. An optometrist or ophthalmologist who regularly sees you for glasses may perform a comprehensive dilated exam that also screens for diabetic eye disease. However, if your routine visit focuses primarily on refraction without a dilated retinal exam, you may need a separate appointment or provider. Let your eye doctor know you have diabetes and ask whether your visit includes a comprehensive dilated retinal evaluation.

What should I do if I notice sudden new floaters or flashes of light?

Sudden new floaters—especially many at once—combined with flashes of light or a shadow in your vision are symptoms that warrant same-day or urgent professional evaluation, not a wait for a routine appointment. These can be signs of a retinal bleed or detachment, which may occur in advanced diabetic retinopathy. Contact your eye care provider or go to an urgent care ophthalmology service or emergency room if you cannot reach your provider quickly. Do not assume the symptoms will resolve on their own.

Next Steps

If you have diabetes and have not had a comprehensive dilated eye exam recently—or if you are unsure when your last one was—this is a good conversation to start with your care team. Bring a list of questions, your most recent A1C and blood pressure readings, and any vision changes you have noticed, however minor they seem.

Consider bringing a specific question about your recommended eye exam interval to your next appointment: "Based on my last eye exam results and my current glucose numbers, what exam interval do you recommend for me?" A clear answer from your care team is far more useful than any general schedule.
