Was Your Premature Baby Treated for ROP? Why Your Retina Still Needs Watching as an Adult
Start Here: the Signs That Cannot Wait
If you were treated for retinopathy of prematurity as a baby, learn these signs now. Call your eye doctor the same day, or go to an emergency room if you cannot reach one, if you notice:
- A curtain or shadow moving across part of your sight
- A sudden shower of floaters, far more than your normal ones
- Flashing lights in one eye, in bursts
- Sudden loss of vision, or a patch of vision that has gone missing
- A painful red eye with blurred sight
These can mean the retina has torn or come loose. Treated early, the outlook is far better than treated late. This is not a wait-and-see list, and it is not a reason to assume the worst either. Most days, nothing happens. The point is to know what to do on the day it does.
Most pages about retinopathy of prematurity are written for parents of newborns. This one is written for the grown-up that baby became, and for the families who still worry about them.
The single most useful thing an adult with a history of ROP can carry is the list above. Everything else on this page explains why.
You were born early. You were checked, and perhaps treated, for ROP in the first weeks of life. Maybe you had laser, or cryotherapy, or an injection. Maybe you were watched and it settled on its own. You may see perfectly well today.
If any of that is you, or describes your son or daughter, this page applies. It applies even if nobody has mentioned your eyes in twenty years.
What ROP Was, and What It Left Behind
The retina's blood vessels finish growing in the last weeks of pregnancy. A baby born early interrupts that process, and the vessels can then grow abnormally. That abnormal growth is retinopathy of prematurity.
In most babies it settles by itself. In some it progresses far enough to threaten the retina, and those are the babies who get treated.
Screening is aimed at babies born at 30 weeks of gestation or under, or weighing 1500 grams or less at birth1. If you were born inside those limits, you were almost certainly examined, whether or not your family remembers it clearly.
Being screened is not the same as being treated. Plenty of people were checked, found to have mild changes, and never needed anything. That still counts as a history worth telling an eye doctor.
Treatment has included laser to the outer retina, injections of anti-VEGF medicine into the eye, and, historically, cryotherapy, which froze the outer retina and is now largely reserved for settings without laser1.
Roughly, cryotherapy belongs to the 1980s, laser took over through the 1990s, and injections came into use much more recently. Knowing which one you had is genuinely useful to a retina specialist, so it is worth asking your parents or requesting your neonatal records while you can.
Why the Risk Does Not End in Childhood
The clearest evidence comes from the trial that established cryotherapy. Among 254 survivors born under 1251 grams with threshold disease, unfavourable structural outcomes at 15 years affected 30 of every 100 treated eyes, and about 52 of every 100 eyes left untreated2.
Treatment clearly helped. It did not make the eye normal. That gap is the whole reason adult follow-up exists, and it is why 'you had it treated' is not the end of the story.
The same trial watched what happened between the ten-year and fifteen-year checks. New retinal folds, detachments or an obscured view of the back of the eye appeared in that window in about 4.5 of every 100 treated eyes, and about 7.7 of every 100 untreated eyes2.
Those are new events, in teenagers, years after everyone had stopped thinking about it. And it continues past that. In a series drawn from 138 patients older than 10 with a history of the condition, about 3.6 of every 100 developed new exudates or worsening fibrovascular changes after age 10, at ages ranging from 13 to 433.
In that same series, one of the five patients described had no symptoms at all. The change was found on a routine examination, not because anything felt wrong.
This is the argument for scheduled checks rather than symptom-led ones. Waiting to notice something works only for the problems that announce themselves, and not all of these do.
What Can Go Wrong in Adult Life
Retinal detachment is described as the most frequent long-term complication and is strongly associated with a poor visual outcome, happening when scar tissue contracts and pulls the retina away from the layers beneath it1.
This is the reason the warning-sign list leads this page. A detachment caught early is a very different situation from one caught late, and the difference is often days rather than months.
High short sight is common after retinopathy of prematurity and can exceed 10 dioptres in severe cases, arising from altered growth at the front of the eye or changes at the back1. If your prescription has always been strong, this is likely why.
A prescription that shifts noticeably in adulthood is worth an examination rather than just new lenses. The change itself is usually harmless. Occasionally it is a signal of something structural, and only a look inside the eye can tell the difference.
Secondary glaucoma can develop from abnormalities of the drainage angle, raising pressure inside the eye and in time damaging the optic nerve1. Glaucoma is usually painless and silent until it is advanced, which is exactly why it is looked for rather than waited for.
Cataract also turns up earlier in this group than in the general population. It is treatable, though surgery in an eye with an ROP history needs a surgeon who knows that history, which is another reason to keep your records.
Strabismus, where the eyes do not line up, and amblyopia, where one eye never developed full sight, are both more common after prematurity. Treatment for these belongs mostly to childhood, but the consequences are lifelong.
If you had laser or cryotherapy, some peripheral retina was deliberately treated, and side vision may be reduced as a result. Ask to have your visual field measured if you have never had it done, particularly if you drive.
How Often You Should Be Checked
A review of late complications concluded that lifelong eye follow-up is needed for everyone diagnosed with retinopathy of prematurity as an infant, because awareness of late complications and appropriate follow-up can reduce severe vision loss4.
How often is a decision for the doctor who examines you, and it depends on what your eyes look like now. Annual is a common pattern. The interval matters less than not falling out of the system altogether.
Expect a dilated examination, because the areas that need watching are at the edges of the retina and cannot be seen otherwise. Dilating drops blur vision for a few hours and leave the eyes sensitive to light, and the American Academy of Ophthalmology says it may not be safe to drive yourself afterwards, so you should arrange for someone to drive you5.
Scans of the retina are usual too. None of it hurts. Plan for a long appointment and a ride home rather than squeezing it into a lunch break.
Say the words 'I was treated for retinopathy of prematurity' at the first appointment, not the third. Add your birth weight and how early you were born if you know them, what treatment you had, and roughly when.
Many optometrists will not have asked, because most adults never mention it. The history changes what an examiner looks for and how far out towards the edge they look, so volunteering it is the single most useful thing you can do.
Living With It Without Living in Fear
Read the figures on this page as descriptions of groups, not forecasts for you. They come from children born decades ago, many of them very sick, treated with methods that have since improved. Your own risk depends on how severe your disease was, what treatment you had and what your retina looks like today.
The honest summary is this: most adults with an ROP history do not have a catastrophe. A meaningful minority develop something that needs attention, often without warning, and that is manageable when someone is looking.
There is no general rule that people with an ROP history must avoid exercise or ordinary activity. Where advice is given, it usually concerns contact sports and activities with a real risk of a blow to the eye, and it depends on your particular retina.
Ask your own specialist rather than assuming either way. Protective eyewear is a reasonable conversation to have if you play racket sports or do work where something could strike your face.
Retinopathy of prematurity is a consequence of being born early, not an inherited condition passed to your children. What can run in families is a tendency to deliver early, so mention your own prematurity to whoever looks after a pregnancy.
If a baby of yours is born early, the screening system that found your ROP will be looking for theirs, and it is considerably better now than it was when you were born.
Common Questions About Adult ROP
Yes, and good vision is not evidence that nothing is happening. In one series of patients followed after age 10, a patient with new changes was picked up on a routine examination with no symptoms at all. Retinal changes at the edge of the retina, and early glaucoma, are both typically silent. An examination looks at places you cannot check for yourself, which is the entire point of having one.
It is common, and it is a gap rather than reassurance. Follow-up frequently lapses in the teenage years when families stop attending and no adult service picks the person up. If that describes you, book a dilated examination and say you have an ROP history. You are not too late, and you will not be told off for the gap.
Ask your parents first, since many remember the hospital and roughly what was done. Neonatal records can often be requested from the hospital that treated you, though how far back records are kept varies. If nothing can be found, an eye doctor can usually tell from examining you whether laser or cryotherapy scars are present.
No. Most adults with a history of it keep useful vision, and treatment as an infant substantially improved the odds compared with no treatment. What the evidence does show is a raised, lasting risk of specific problems that can be treated when found early. That is an argument for regular checks, not for expecting the worst.
The infant disease does not restart, but the eye it left behind can develop new activity. One series described new exudates and worsening fibrovascular changes in patients aged 13 to 43, well after everyone considered the condition finished. This is uncommon. It is also the reason that 'it was dealt with in 1994' is not a safe assumption to carry through life.
Both treatments deliberately treated peripheral retina to save the centre, and that trade-off can reduce side vision. It is not usually something you notice day to day, though it can show up on a visual field test. If you drive, having your field formally measured at least once is sensible, so you know where you stand rather than guessing.
More Questions About Checks, Records and Risk
A retina specialist is ideal, and an ophthalmologist comfortable with peripheral retinal examination is a reasonable alternative. An optometrist can perform the examination and refer on, provided you tell them the history so they know to look carefully at the periphery. What matters most is that whoever sees you knows about the ROP and dilates your eyes.
Carry the history yourself rather than relying on records following you. Keep a note on your phone with your gestational age, birth weight, the treatment you had and the date of your last dilated examination. Hand that over at any new practice. Records transfer between systems unreliably, and a one-line summary from you closes the gap immediately.
Partly. Untreated eyes in the long-term trial actually fared worse structurally than treated ones, so having escaped treatment is not the same as having escaped risk. Mild disease that regressed fully carries less concern than severe disease. Tell an eye doctor what you know and let them decide what surveillance suits your eyes.
If they were born early enough to have been screened, yes, it is worth them having a dilated examination and mentioning the history. Adults often do not know they were screened as infants. If you are the parent who remembers the neonatal unit, you may be holding information they need, so tell them what you remember and encourage the appointment.
