Optomap is an ultra-widefield retinal imaging technology that captures up to 200 degrees of the retina in a single scan, wide enough that most patients don’t need dilating drops to get a full view of the back of the eye. As part of comprehensive eye exams at Lucent Family Eye Care, it lets patients drive and return to work immediately after their appointment.
Dilating drops have long been the standard way to get a clear view of the retina, but they come with a real tradeoff: blurred near vision and light sensitivity that can last for hours, making it hard to drive, work, or read comfortably afterward. Optomap imaging was developed specifically to solve that problem, and for most patients, it succeeds.
What Optomap Actually Captures
A traditional dilated exam, done with an ophthalmoscope after drops widen the pupil, typically lets a doctor view somewhere around 15% of the retina directly. Optomap, by contrast, captures up to 200 degrees — roughly 82% of the retina — in a single ultra-widefield scan, without needing to widen the pupil first.
The device uses low-power laser light to scan through a natural, undilated pupil, producing a detailed digital image of the retina in about half a second per eye. Because the scan happens so quickly and doesn’t require dilation, it’s suitable for most patients, including many who find dilation uncomfortable or simply don’t have time to wait around for drops to wear off.
Why Skipping Dilation Matters
Dilating drops widen the pupil for several hours, during which near vision blurs and eyes become unusually sensitive to light. For someone who drove themselves to the appointment, or who has work or errands immediately after, this is a genuine inconvenience — some patients have historically avoided or delayed eye exams specifically because of it.
Because Optomap captures a comparably wide view without dilation, patients can typically leave their exam and resume driving, working, or reading right away. This is one of the more practical reasons the technology has become a standard part of comprehensive eye exams rather than an optional add-on.
What Optomap Is Actually Used to Detect
The retina is the only place in the body where blood vessels can be viewed directly and non-invasively, which makes retinal imaging valuable for more than just eye-specific conditions. Optomap imaging is used to screen for retinal detachment and retinal tears, particularly in the peripheral retina that traditional undilated exams often miss. Diabetic retinopathy, which causes changes to retinal blood vessels, is another key target, since Optomap’s wide field of view helps catch early changes before they threaten vision. Macular degeneration and other age-related retinal changes, glaucoma-related optic nerve changes, and general eye health markers such as retinal holes or lattice degeneration can also be identified during the same scan.
Because the image is captured digitally, it can also be saved and compared against future scans, making it easier to track subtle changes in your retina over successive visits — something that’s harder to do with an ophthalmoscope-only exam that isn’t recorded as an image.
Combining Optomap With OCT Imaging
At Lucent Family Eye Care, Optomap is paired with OCT (optical coherence tomography) imaging using the Optos Monaco system, which combines both technologies in one device. While Optomap captures a wide surface view of the retina, OCT produces a cross-sectional scan, essentially a slice-by-slice view through the retina’s layers.
This combination matters because some conditions show up more clearly as a surface change, and others as a structural change within the retinal layers. Glaucoma-related nerve fiber thinning, for example, is often easier to detect on OCT’s cross-sectional imaging than on a surface photo alone, while a peripheral retinal tear is more visible on the wide-field Optomap image. Using both together gives a more complete picture than either alone.
When Traditional Dilation Is Still Used
Optomap doesn’t fully replace dilation in every situation. Certain conditions — including some cases requiring a very detailed view of specific retinal areas, or monitoring an existing diagnosis that needs a particular examination method — may still call for a traditional dilated exam. Some patients with very small pupils, significant cataracts, or certain eye conditions may also get a more limited Optomap image, in which case dilation might be recommended as a supplement rather than a replacement.
Your optometrist will determine during your exam whether Optomap alone provides sufficient information or whether dilation is also needed for your specific situation.
Image Quality Factors That Can Affect a Scan
A few conditions unrelated to the retina itself can affect how clear an Optomap image comes out. Significant cataracts, corneal scarring, or a very small natural pupil can partially obstruct the light path the scan relies on, resulting in an image that’s harder to interpret in certain areas. Droopy eyelids or difficulty holding the eye open steady during the brief capture window can also affect image quality on the first attempt.
In most of these cases, the scan can simply be repeated, sometimes with minor positioning adjustments. When image quality is consistently limited by one of these factors, your optometrist may recommend a traditional dilated exam for that specific area of concern rather than relying on a partial Optomap image. This is decided case by case during your visit, based on the actual image captured, rather than assumed in advance from your health history alone.
What to Expect During an Optomap Scan
The scan itself takes only a few seconds per eye. You’ll be positioned in front of the device and asked to look at a small target light while it captures the image — there’s no need to hold your eye open manually, and most patients find it noticeably quicker and more comfortable than waiting through dilation. Results are available immediately and are typically reviewed with you during the same visit as part of your comprehensive eye exam.
Why Optomap Fits Well Into Pediatric and Diabetic Exams
Two patient groups in particular benefit from the no-dilation approach. For pediatric eye exams, a quick, non-invasive scan is far easier for a young child to tolerate than sitting still through the light sensitivity and blurred vision that follow dilating drops, and it removes one of the more common reasons parents delay a child’s first comprehensive exam.
For patients managing diabetes, regular retinal imaging is not optional — diabetic retinopathy is monitored specifically through changes in the retina’s blood vessels, and catching those changes early is what prevents vision loss. Optomap’s wide field of view makes it well suited to this kind of repeated monitoring, since the same digital images can be compared visit to visit to track whether changes are progressing. This directly supports the diabetic eye exam coverage details outlined for MSP-eligible patients, since the imaging itself is part of what makes these visits medically necessary.

Optomap and OCT imaging are included as part of comprehensive eye exams at Lucent Family Eye Care, giving Dr. Linda Yee a detailed, wide-field view of your retina without the inconvenience of dilating drops for most patients. If it’s been a while since your last comprehensive exam, or you’ve been putting one off because of dilation, book an appointment to see how the no-dilation option works for you.
Frequently Asked Questions
No. Optomap is one diagnostic tool used within a comprehensive eye exam, alongside vision testing, eye pressure checks, and a general health assessment. It specifically improves how the retina is imaged, rather than replacing the rest of the exam.
No. The scan itself takes about half a second per eye and involves looking at a small target light. Most patients find it quicker and more comfortable than waiting through pupil dilation.
Yes, Optomap is generally suitable for children and is often used as part of pediatric eye exams, since it avoids the discomfort and light sensitivity that dilating drops can cause in younger patients.
Most patients don’t need dilation when Optomap is used, but certain conditions, very small pupils, or specific monitoring needs may still call for a traditional dilated exam as a supplement. Your optometrist will let you know if this applies to you.
Optomap is typically done at each comprehensive eye exam, which for most adults is annually or every two years, though certain conditions like diabetes may call for more frequent retinal imaging.
Retinal imaging technology like Optomap is generally considered part of the broader eye exam and follows the same coverage rules — MSP contributes toward medically necessary exams, with any remaining cost typically direct billed to your extended health plan.
Optomap captures a wide surface photo of the retina, while OCT produces a cross-sectional scan through the retina’s layers. They show different types of detail, which is why Lucent Family Eye Care uses both together for a more complete assessment.
Optomap does not use dilating drops and involves only a brief scan of low-power light, so it’s generally considered a comfortable, low-intervention option for pregnant patients who still need a comprehensive eye exam. Any specific concerns can be discussed with your optometrist before the scan.
