Retinopathy of Prematurity is an eye condition that can affect babies born early or at low birth weight, where the blood vessels of the retina haven't finished developing. Most babies who are screened on time never need treatment. The babies who do need it, need it within a narrow window — which is why screening cannot wait for the "right time" to feel ready.
ROP is graded by stage (how abnormal the vessels look) and zone (how far the abnormal area extends). Most cases are mild and resolve on their own with continued monitoring.
Mild abnormal vessel growth at the boundary of developed and undeveloped retina.
Usually just needs continued monitoring; most regress on their own.More significant abnormal vessel growth, sometimes with extra "plus disease" activity.
This is usually the stage where treatment starts to be considered.Partial to complete retinal detachment.
Needs urgent, more complex surgical treatment.Extra swelling and tortuosity of vessels near the optic disc.
A marker of disease activity that can shift the treatment decision.National guidelines set the screening criteria; your neonatologist will confirm if your baby qualifies. As a general guide:
Born at or before 34 weeks of gestation
Birth weight of 2000g or less (or higher weight with an unstable course, at the treating team's discretion)
Babies who received oxygen therapy or had a complicated NICU course
Any baby a neonatologist specifically flags for screening, regardless of the above
Typically between 3–4 weeks after birth, done at the bedside in the NICU or nursery.
Repeat exams every 1–3 weeks depending on findings, until the retina finishes developing or treatment is needed.
Laser or an anti-VEGF injection, done promptly once threshold disease is reached.
Babies with ROP — treated or not — are followed into childhood for glasses, squint and lazy eye.
The standard treatment for threshold disease.
Stops abnormal vessel growth at the bedside or in the NICU under sedation.An intravitreal injection used in selected zone-I or aggressive disease.
Often needs closer, longer follow-up than laser alone.For advanced disease with retinal detachment (stage 4–5).
Aims to preserve as much vision as possible; outcomes vary by stage.A NICU stay is stressful enough without a new diagnosis added to it. A few things that help parents through ROP screening:
The exam looks more uncomfortable for your baby than it is — most babies settle quickly afterward
A mild finding today does not mean your baby will need treatment
Missing a scheduled screening is the single biggest risk factor for a bad outcome — we will remind you, but please protect these appointments
We explain every finding in plain language, at every visit, not just when something changes

Numbing drops are used, and babies are swaddled and comforted through it. Most settle within a few minutes of finishing.
No — most babies screened for ROP never need treatment. Screening exists to catch the minority who do, in time.
Please call us immediately to reschedule. ROP can progress quickly, and a delayed screening is the most preventable cause of a missed treatment window.
Often, yes, at some point — along with monitoring for squint or lazy eye. This is normal and manageable with routine paediatric eye follow-up.
Disease activity is monitored closely after treatment; further treatment is occasionally needed, which is why follow-up continues even after laser or injection.
