Can pregnancy itself cause retinal detachment?

Not usually, but it can worsen the risk if you already have myopic degeneration or prior retinal issues.

Should everyone with myopia get an eye exam in pregnancy?

No, but if your myopia is severe, or you’ve had laser treatment or floaters before, a retinal exam is a good precaution.

Is screen time dangerous during pregnancy for myopic people?

Not dangerous, but can increase discomfort. Use blue light filters, lubricating drops, and take breaks.

Will I need a C-section because of my myopia?

Only if your ophthalmologist recommends it after a retinal evaluation. Most people with myopia deliver vaginally.

Pregnancy, Myopia & Retinal Detachment: Eye Risks You Should Know

You don’t expect your eyes to change in pregnancy. But many people with myopia report unexpected shifts, vision blurring, dry eye, or new floaters. If you already have high myopia (over -6.00), your retina is structurally thinner than average. What you may not realise is how pregnancy-related hormonal changes, fluid shifts, and blood pressure fluctuations can further affect retinal stability.

What Is High Myopia and Why It Affects the Retina

High myopia changes the eye’s structure in a way that makes the retina more fragile.

Axial elongation: The eyeball grows longer, stretching the retina over a larger surface area.
Retinal thinning: A thinner retina is more prone to holes, tears, and detachment, especially in the peripheral zones.
Lattice degeneration: Seen in many people with high myopia, this causes abnormal thinning in patches, often before symptoms arise.
Surgical history matters: If you've had LASIK, laser photocoagulation, or vitrectomy in the past, it may alter your retina’s resilience.

Why Pregnancy Can Influence Retinal Health

Pregnancy affects fluid dynamics, vascular tone, and hormone levels throughout the body, and your eyes are no exception.

Hormonal changes: Increased oestrogen and progesterone can shift corneal thickness and intraocular fluid balance.
Blood pressure swings: Hypertensive conditions like preeclampsia may impact retinal blood vessels and increase detachment risk.
Fluid retention: Systemic swelling might influence vitreous consistency, increasing mechanical stress on the retina.
Dry eye: Common in pregnancy, especially in screen-heavy work, causing discomfort (but not detachment).
Visual disturbances: Migraines or blurring may arise from hormonal fluctuations, though usually benign.

When the Risk Is Higher: Vulnerable Situations to Watch

Not all myopic pregnancies carry eye risk, but certain pre-existing conditions require close monitoring:

Refractive error above -6.00: Indicates structural thinning and higher detachment susceptibility.
Lattice degeneration: Already compromised retinal tissue, especially in the peripheral zones.
History of retinal tear or detachment: Even if treated, the area remains weaker.
Floaters, flashes, or visual shadows: May suggest vitreous traction — should be examined immediately.
Family history: Genetic predisposition to retinal thinning or detachment can increase vulnerability.

How Eye Health Is Monitored in Pregnancy

Ophthalmic screening isn’t routine in pregnancy, but it’s often worth considering for high-risk myopic patients.

Baseline retinal check in the first trimester: Especially if you’ve had retinal treatment or severe myopia.
Indirect ophthalmoscopy: To check for retinal thinning, tears, or holes.
OCT (Optical Coherence Tomography): For central retina (macula) monitoring.
Emergency symptoms to report immediately:

Treatment and Management If Risks Are Identified

Prophylactic laser: Preventive laser photocoagulation may be recommended for lattice degeneration, especially before the third trimester.
Rest and screen control: Reduce strain, take screen breaks, and stay hydrated to ease discomfort.
Monitor blood pressure: Retinal complications are more likely with gestational hypertension or preeclampsia.
Urgent care for detachment: Retinal surgery may be performed during pregnancy in emergencies. Timing depends on severity and gestational age.

What About Labour and Delivery?

This question causes a lot of anxiety, but here’s what the evidence says.

The act of pushing (Valsalva) may raise intraocular pressure briefly, but this isn’t the primary cause of retinal detachment.
If you’ve had a recent tear, detachment, or severe degeneration, your ophthalmologist may suggest assisted vaginal delivery or C-section.
It is not automatically required for all highly myopic individuals. A detailed retinal exam must guide this decision.

It’s valid to feel scared if you’ve experienced vision shifts or already live with severe myopia. Here’s what helps:

Keep a symptom log: Note floaters, flashes, or blurriness, and bring it to your checkups.
Insist on specialist input: A general OB may not grasp retinal nuance. You’re not overreacting.
Don’t dismiss vision anxiety as hormonal; protecting your sight is legitimate and essential.
Rest isn’t laziness: Reducing eye strain during pregnancy is an act of care, not indulgence.

Pregnancy may feel like a time to monitor your womb, but for some, it also becomes a time to protect your eyes. If you have high myopia or a retinal history, early checks, symptom awareness, and open conversations with both your OB and ophthalmologist can make a big difference. Retinal detachment is rare, but staying informed means you don’t have to panic at every flicker. You’ll know what to look for, what to ignore, and when to act.
