New Floaters During Pregnancy: Normal Hormone Change, or Something to Get Checked?
New Floaters in Pregnancy at a Glance
Some new floaters need a same day eye exam. Call your eye doctor right away if you notice any of these:
- A sudden shower of floaters, or many new specks at once
- Flashing lights or streaks of light, easiest to see in a dark room
- A dark curtain or shadow moving in from the side of your vision
- A drop in vision, or a part of your sight that has gone missing
- New floaters plus a headache that will not go away, swelling of your face or hands, or pain in your upper belly
The first four signs point to the retina, the light sensing layer at the back of your eye. Most turn out to be a harmless gel change. Anyone with these symptoms should be seen as soon as it can be arranged, by a doctor trained to look at the whole retina1. Across 17 studies, about 14 of every 100 people seen for sudden floaters or flashes had a retinal tear2. A tear caught early is usually sealed in the office in one visit. The last sign belongs to your blood pressure, so call your obstetric team the same day too. Seeing spots or changes in eyesight are on the list of preeclampsia symptoms to report right away3.
Pregnancy changes your eyes in real ways, but new floaters are not one of them. The eye changes described in pregnancy include drier eyes, a thicker and slightly steeper cornea later in pregnancy, a temporary shift toward nearsightedness, and a drop in eye pressure of about 2 to 3 mm Hg4. A published review of pregnancy eye changes lists those effects and does not describe pregnancy altering the vitreous gel or causing floaters5. So ''it is probably my hormones'' is a fair first thought and a poor stopping point. Your floaters need the same look anyone else would get.
Most new floaters come from the clear gel inside the eye pulling away from the retina. That separation is called a posterior vitreous detachment. It usually happens between the ages of 45 and 65, though the gel can separate earlier in people who are nearsighted, who have had an eye injury, or who have had eye surgery6. Most pregnancies happen well before that age window, which is why floaters at 28 or 34 deserve a look rather than a shrug. The one problem worth catching, a retinal tear, is treated in the office when it is found early.
What Floaters Are, and What Pregnancy Actually Changes
Floaters are specks, dots, circles, lines or cobwebs in your vision, made by clumps of gel or cells inside the eye casting shadows on the retina7. You see the shadow, not the clump, which is why a floater drifts when you move your eye and darts away when you look straight at it. Floaters show up most against a plain bright background, so a white wall or a phone screen at night makes one look worse without anything having changed.
Pregnancy does affect your eyes. Hormone changes lower tear gland function, so eyes feel drier and contact lenses feel less comfortable. Corneal thickness and curvature rise with water retention in the second and third trimesters, and eye pressure falls slightly before returning to normal afterwards4. Because the prescription shifts and then settles, laser vision correction is not done during pregnancy and waits until three to six months after delivery4. None of these changes produce new specks drifting across your sight.
What Can Cause New Floaters While You Are Pregnant
This is the common answer at any age. As the vitreous thickens or shrinks, clumps form and cast shadows, and floaters often arrive with a vitreous separation7. Flashes can come with it, because the gel tugs on the retina as it lets go. Being nearsighted, having had cataract surgery, and having had inflammation inside the eye all make floaters more likely7. If you are strongly nearsighted, say so when you book. The gel separates earlier than usual in people who are nearsighted6.
This is why the visit is not optional. When the gel pulls away, it can take a piece of retina with it. In a two year study of 1,010 community referrals for flashes and floaters, 896 had a vitreous separation. About 10 of every 100 of them had a retinal tear and about 1 of every 100 already had a retinal detachment at the first visit8. Most people are fine, and enough are not that a same day look is worth your afternoon. A detached retina stops working while it is detached, so vision goes blurry or blank in that area9.
If you had diabetes before this pregnancy, a sudden cloud of dark floaters can be blood in the gel. Some studies suggest a higher risk of vitreous bleeding brought on by straining in people with proliferative diabetic retinopathy, the advanced stage where fragile new vessels grow on the retina10. Blood looks like soot, smoke, or a swarm of dark dots that arrived over minutes to hours, and it needs an urgent examination rather than a wait and see week. Laser photocoagulation is used during pregnancy and remains the mainstay for holding diabetic retinopathy back10.
Inflammation inside the eye is called uveitis. Having had inflammation inside the eye makes floaters more likely7, and uveitis usually announces itself with light sensitivity, aching or blurring rather than floaters alone. In a review of uveitis in pregnancy, flares tended to settle from the second trimester onward, with the lowest activity in the third trimester and a rise again after delivery11. If you have a history of uveitis, expect a quieter middle of pregnancy, and expect your eye doctor to want to hear from you after the birth.
How the Symptoms Themselves Differ
Flashes are arcs or streaks of light, most noticeable in the dark. They mean the gel is pulling on the retina. Floaters plus flashes earns a prompt dilated examination rather than a routine appointment. A drop in vision you notice yourself was the symptom most strongly linked to a retinal tear, and new symptoms in the six weeks after a vitreous separation, especially at least 10 new floaters, raised the odds of a tear2. Counting matters: ''a few more'' and ''dozens at once'' are different reports.
A dark curtain coming in from one side, a shadow that stays put when you move your eye, or a missing corner of vision suggests the retina has begun to come away. This is not a wait until morning symptom. Reattachment succeeds more often and vision does better when a detachment is repaired early, especially before it involves the macula, the central part of the retina6. Detachments are repaired with a gas bubble that pushes the retina back, with surgery that removes the gel and replaces it with air, gas or oil, or with a silicone band sewn to the outside of the eye9.
Vision symptoms in the second half of pregnancy have a second possible home. Blurred vision is the most common visual symptom in preeclampsia and eclampsia, along with disturbed color vision and a reduced field of vision12. These arrive alongside other signals such as a headache that will not go away, swelling of the face or hands, or upper abdominal pain3. Spots or blurring in that company belong to your obstetric team, whatever your eyes turn out to be doing.
Use this to describe what you are seeing when you call, not to decide whether to call.
| What you notice | Where it usually points | How fast |
|---|---|---|
| New floaters, one eye, with flashes | Vitreous separation, possible tear | Same day exam |
| Curtain, shadow, or lost side vision | Possible retinal detachment | Emergency, do not wait |
| Cloud of dark specks, known diabetes | Possible bleeding in the gel | Urgent, same day |
| Spots or blur in both eyes, headache | Blood pressure problem in pregnancy | Call obstetric team same day |
| Old specks, nothing new | Longstanding floaters | Routine appointment |
Preeclampsia, Blood Pressure, and Your Vision
Preeclampsia usually develops after 20 weeks and can also appear in the weeks after childbirth. Its symptoms include seeing spots or changes in eyesight, swelling of the face or hands, a headache that will not go away, upper abdominal pain, nausea and vomiting in the second half of pregnancy, sudden weight gain and difficulty breathing3. Report any of these the same day rather than at your next visit. Being checked means a blood pressure cuff, a urine sample and blood tests.
Symptoms are a prompt to be assessed, not a test in themselves. Pooling six studies of 2,573 women with preeclampsia, visual disturbance flagged about 27 of every 100 women who went on to have a serious complication, while correctly clearing about 81 of every 100 who did not, so having a symptom raises concern more usefully than lacking one rules trouble out13. So no vision symptom is reassuring enough to skip the blood pressure check, and none tells you on its own what is happening.
The eye findings in preeclampsia involve the blood vessels, not the gel. Narrowing of the retinal arterioles is the most common finding, in about 70 of every 100 cases, and about 1 to 2 of every 100 patients with severe high blood pressure, protein in the urine and swelling in the third trimester lose vision from fluid collecting under the retina12. After delivery and treatment of the blood pressure, that fluid clears quickly and vision recovers fairly completely in most patients12. That outlook depends on the blood pressure being found and treated.
Getting Your Eyes Checked While You Are Pregnant
The visit that answers the floater question is a dilated look at the whole retina, including the far edges where tears usually sit. People with symptoms of a possible vitreous separation or retinal detachment should be examined as soon as is feasible, by an ophthalmologist skilled in examining the full retina1. Expect a head mounted light, a hand held lens, and gentle pressure on the outside of the lid so the far edge rolls into view. That last part is quick, and it is what finds tears.
Yes, when there is a reason to look. One clinical review describes the shorter acting drops tropicamide and cyclopentolate as safer choices in pregnancy and breastfeeding than longer acting agents, suggests avoiding phenylephrine unless tropicamide alone leaves the pupil too small, and describes occasional dilation as acceptable while routine repeat dilation is avoided where possible14. Say that you are pregnant when you book and again at the chair. That is what shapes which drop the practice reaches for.
Scanning the retina with light needs no dye and no injection, so it is used freely. Dye tests are the ones your team weighs. Fluorescein dye crosses the placenta. No dye related harm to the baby has been documented, and the dye stays in breast milk for up to 72 hours10. That is a conversation to have if a dye test is proposed. For a floater question, no dye is needed, because the dilated look answers it.
If You Have Diabetes and You Are Pregnant
Pregnancy is a period when existing diabetic eye disease can move. New diabetic retinopathy appears during pregnancy in about 15 of every 100 patients with diabetes that predates the pregnancy, and about 6 of every 100 move from the earlier stage to the proliferative stage. Worsening is linked to type 1 diabetes, more retinopathy at the start, longer duration, poor glucose control, rapid tightening of control, high blood pressure and existing kidney disease10. Tightening your glucose is still the right move. It means your eyes get watched while you do it.
People with diabetes that predates pregnancy should be counseled about the risk of retinopathy developing or progressing, and dilated eye examinations should happen ideally before pregnancy and in the first trimester, then every trimester and for a year after delivery as the degree of retinopathy indicates15. Severe disease short of the proliferative stage is followed more closely, at intervals of about one to three months10. If nobody has booked this, ask. It is a standing recommendation, not a reaction to symptoms.
Diabetes that first appears during pregnancy sits in its own category. The trimester by trimester eye examination recommendation is written for people whose diabetes predates the pregnancy, and the guideline does not extend it to gestational diabetes15. That covers retinopathy screening only. If you develop new floaters, flashes or a shadow, the same day advice above applies to you exactly as it does to anyone else.
What Happens Next, and the Realistic Outlook
Most floaters and flashes need no treatment and tend to become less noticeable over time. Surgery exists for severe cases, carries risks, and is rarely recommended7. Your brain also learns to ignore a stable floater over weeks to months, which is why a speck that dominated week 30 can be hard to find by week 40.
Treatment for a retinal break makes a seal in the attached retina immediately around the tear, using laser or a freezing probe, and acute horseshoe shaped tears are treated promptly6. It is usually done in the office in one sitting with numbing drops, and it aims to stop fluid getting under the retina and lifting it further. It does not clear the floaters you already see, and it is far smaller than repairing a detachment later.
In a prospective study of 896 people referred from the community with flashes and floaters, about 10 of every 100 had a retinal tear at the first examination8. People whose first examination shows a vitreous separation and no break have about a 2 in 100 chance of a break appearing in the weeks that follow, and anyone with pigment, vitreous or retinal bleeding, or visible pulling on the retina is asked back for a second examination within six weeks, or promptly if new symptoms appear6. In that same community study, about 3 of every 100 with a clear first look had a tear at the two month check8. One clear examination is good news, not a reason to ignore a second wave.
Many people worry that pushing will tear the retina. The evidence here is thin. In a small series of 10 women with 19 deliveries who had a previous detachment, extensive lattice degeneration or treated retinal breaks, no change in retinal status was found after delivery16. In a survey, obstetricians recommended cesarean section more often than ophthalmologists did for these patients, and its authors concluded that treated high risk retinal findings are not in themselves a reason against a vaginal delivery17. Your delivery plan belongs to your obstetric team, told about your eye history.
When to Call, and Who to Call
Call your eye doctor the same day for a sudden increase in floaters, new flashing lights, a curtain or shadow in your side vision, or any drop in vision. Anyone with a vitreous separation is told to notify their ophthalmologist as soon as possible about a substantial change in symptoms, including more floaters or flashes, loss of side vision, or reduced sharpness1. If your practice cannot see you, an emergency department with eye cover is the right destination. Being sent home after a normal examination is a good outcome.
If vision symptoms come with a headache that will not shift, swelling of the face or hands, upper belly pain, or a blood pressure that has been running high, your obstetric team goes first. Changes in vision count among the severe features of preeclampsia, and these symptoms are the ones patients are asked to report right away3. You can do both in one day. An eye examination is no substitute for a blood pressure check, and a blood pressure check will not find a retinal tear.
An optometrist or a general ophthalmologist can dilate you and examine the retina, and either refers you onward the same day if they find a tear or detachment. A retina specialist seals tears and repairs detachments. Your obstetric team owns the blood pressure side. Tell each about the other, particularly if you have diabetes, past retinal problems, or a strong glasses prescription.
Common Questions About Floaters in Pregnancy
Not as far as published descriptions of pregnancy eye changes go. Reviews describe drier eyes, a thicker and steeper cornea, a temporary nearsighted shift, lower eye pressure and eyelid pigmentation, and do not describe pregnancy changing the vitreous gel or causing floaters5. New floaters in pregnancy get handled as new floaters in anyone, which means an examination rather than an explanation. Most examinations are normal, and the visit is short.
You are younger than the usual window, which is a reason to be checked rather than to relax. A vitreous separation usually occurs between the ages of 45 and 65, though the gel can separate earlier in people who are nearsighted, who have had an eye injury, or who have had eye surgery6. Being nearsighted is the usual explanation in a younger person, so mention your prescription when you book.
Your eye doctor will pick the shorter acting drop and use it only when the examination needs it. Tropicamide and cyclopentolate are described as safer choices in pregnancy and breastfeeding than longer acting agents, phenylephrine is avoided unless tropicamide alone leaves the pupil too small, and occasional dilation is described as acceptable14. Say you are pregnant when you book. The alternative, an undilated look that misses the retinal edge, carries its own risk.
Floaters alone are not a typical preeclampsia symptom, but vision changes in the second half of pregnancy are on the list to report. Blurred vision is the most common visual symptom in preeclampsia, with color vision disturbance and a reduced field, usually alongside other signs such as a persistent headache or swelling12. Seeing spots or changes in eyesight sit on the list of symptoms to report right away3. One call to your obstetric team settles it with a blood pressure cuff.
Yes. Cover each eye in turn so you can tell the practice which side it is. Symptoms of a possible vitreous separation or retinal detachment call for examination as soon as is feasible, by a doctor equipped to see the whole retina1. Tell the practice which eye, and whether there are flashes.
Floaters are not among the described effects of pregnancy, so delivery is not what settles them. Most floaters need no treatment and tend to become less noticeable over time7. What usually happens is that the floater stays and you stop noticing it, as your brain learns to filter it out. A floater that is clearly getting worse rather than settling is worth another examination.
More Questions Pregnant Patients Ask
Yes. People whose diabetes predates pregnancy should be counseled about the risk of retinopathy developing or progressing, with dilated examinations ideally before pregnancy and in the first trimester, then every trimester and for a year after delivery as the degree of retinopathy indicates15. If nobody has arranged it, ask your diabetes team or eye clinic to book it now. New dark floaters in diabetic retinopathy can be bleeding, and need an urgent look.
That decision belongs to your obstetric team, and eye history alone does not usually settle it. In a survey, obstetricians recommended cesarean section more often than ophthalmologists did for otherwise healthy patients with a treated retinal hole, tear or detachment, and its authors concluded that treated high risk retinal findings are not in themselves a reason against a vaginal delivery17. A small series of women with high risk retinal findings found no change in retinal status after delivery16. Get both teams into one conversation.
Only if your symptoms change, unless you were told otherwise. People with a clear first examination have about a 2 in 100 chance of a break appearing in the following weeks, and those with pigment or bleeding in the gel are asked back within six weeks, or sooner if new symptoms appear6. Treat a clear examination as a baseline: another shower of floaters, new flashes or a shadow means you call again.
Most floaters and flashes need no treatment, and the surgery that exists for severe cases carries risks and is rarely recommended7. No drop or supplement appears in that guidance. What helps is practical: know which eye and roughly how many, so a real change is obvious to you. Keeping your blood pressure and glucose reviews on schedule matters more than anything aimed at the floaters.
- Was my retina examined all the way to the edge, with the lid pressure part included?
- Did you see pigment or blood in the gel, and does that change how soon I come back?
- Is my vitreous separation complete, or still in progress in this eye?
- Given my glasses prescription, am I in a higher risk group for a tear?
- What exactly should make me call you before my next appointment?
