Eclampsia-Associated Retinopathy (EAR)

Eclampsia-associated retinopathy means eye and retina problems that happen because of very high blood pressure and body-wide blood vessel stress during preeclampsia/eclampsia. Preeclampsia is high blood pressure that starts after 20 weeks of pregnancy and harms organs; eclampsia is when seizures happen on top of that. These problems can make the tiny blood vessels in the back of the eye (retina and choroid) spasm, leak, or become blocked. That can cause blurred vision, flashing lights, dark spots, loss of parts of the visual field, or—rarely—temporary severe vision loss. ACOGPMC

What doctors see in the eye can include retinal artery narrowing, cotton-wool spots (tiny nerve-fiber “infarcts”), retinal hemorrhages, Elschnig spots (patches from choroidal ischemia), and sometimes a “serous/exudative retinal detachment” where fluid collects under the retina. This detachment is uncommon (about <1% in preeclampsia and up to ~10% in eclampsia) and usually gets better after blood pressure is controlled and the pregnancy is delivered. EyeWikiAAO

Pregnancy-related high blood pressure and endothelial dysfunction reduce blood flow and oxygen to the choroid/retina, leading to choroidal ischemia and breakdown of the outer blood-retina barrier at the retinal pigment epithelium (RPE). This chain reaction explains the yellow RPE plaques, cotton-wool spots, and fluid under the retina. In some patients, vision symptoms come from the brain (posterior reversible encephalopathy syndrome, or PRES), which also usually improves after blood pressure is treated. Retina TodayPMCLippincott Journals

Eclampsia is a dangerous rise in blood pressure with seizures during pregnancy or just after delivery. When blood pressure and abnormal blood vessel signals suddenly surge, the tiny blood vessels that feed the light-sensing layer of the eye (the retina) and the deeper “cooling/feeding blanket” under it (the choroid) can spasm, leak, or clog. That stress can blur vision, make dark spots or flashing lights, or even cause a pocket of clear fluid to lift the retina off its base (a serous/exudative retinal detachment). These eye problems are grouped as eclampsia-associated retinopathy. The eye damage often improves after blood pressure is controlled and the pregnancy is stabilized or completed, but it can be severe while it is happening and needs urgent care. In medical studies, serous (exudative) retinal detachment is found in roughly 1–2% of people with preeclampsia/eclampsia, and the main driver is spasm and ischemia (low blood flow) of the choroid with leakage beneath the retina. EyeWikiPMC

What is happening inside the eye

In eclampsia, blood pressure shoots up and the inner lining of blood vessels (the endothelium) becomes leaky and irritable. Retina arterioles can clamp down (vasospasm), the choroid can lose flow (ischemia), and the barrier that normally keeps fluid out of the subretinal space can fail. On scans, doctors see thickening and flow defects in the choroid, which matches the idea that ischemia and congestion trigger fluid to collect under the retina (serous/exudative retinal detachment). Many cases settle after delivery and blood pressure control, but pigment changes can linger. PMC+1

Types of eclampsia-associated retinopathy

1) Hypertensive retinopathy pattern.
Small arteries in the retina narrow, look shiny (“copper wiring”), and pinch veins where they cross; there can be flame-shaped or blot hemorrhages, pale fluffy cotton-wool spots, hard exudates, and sometimes swelling of the optic disc. This is the same pattern seen with very high blood pressure in non-pregnant adults, but in eclampsia it can appear rapidly. NCBI

2) Acute hypertensive choroidopathy with Elschnig spots.
The choroid (the vascular bed under the retina) becomes ischemic. That makes small yellowish lesions called Elschnig spots and, in more severe cases, causes fluid to lift the retina (serous/exudative detachment). OCT and OCT-angiography can show choroidal thickening and patchy flow loss in the choriocapillaris. PMCPubMed

3) Serous (exudative) retinal detachment.
Clear fluid collects under the retina without a tear. It is usually bilateral, often appears around delivery, and usually improves after the systemic disease is controlled—though temporary vision loss can be striking. EyeWikiPMC

4) Purtscher-like retinopathy (rare).
This is a sudden, severe ischemic injury to the retina with cotton-wool spots and areas of whitening (“Purtscher flecken”). It has been reported with eclampsia and HELLP, sometimes alongside pancreatitis or prolonged labor. Vision can be quite poor at first and recovery is variable. PMCAAO Journal

5) Optic disc edema and macular edema.
Very high blood pressure can swell the optic nerve head and the central retina (macula), adding to blur and distorted vision. NCBI

6) PRES-related visual loss (not a retinal disease but often overlaps).
Some people with eclampsia develop posterior reversible encephalopathy syndrome (PRES)—brain swelling in the occipital lobes—causing sudden visual loss or field cuts even when the eyes look normal. Clinicians consider PRES and retinal disease together because both can appear during the same crisis. Lippincott JournalsBMJ Case Reports

Causes

1. Sudden severe hypertension. Fast spikes in blood pressure clamp retinal and choroidal vessels and damage the vessel lining. NCBI

2. Endothelial dysfunction of preeclampsia. The vessel lining becomes leaky and inflamed, so fluid escapes into the retina and under it. mehdijournal.com

3. Choroidal ischemia. The choriocapillaris loses flow; this is central to serous detachment in eclampsia. PMC

4. Breakdown of the outer blood-retina barrier. Stress at the retinal pigment epithelium (RPE) lets fluid collect under the retina. PMC

5. Arteriolar vasospasm. Reflex vessel tightening reduces oxygen to retinal nerve fiber layers, making cotton-wool spots. NCBI

6. Hypercoagulability and microthrombi. Sticky blood in preeclampsia/HELLP may form tiny clots that worsen ischemia. PMC

7. HELLP syndrome. Low platelets and hemolysis promote bleeding and ischemia in the retina and choroid. PMC

8. Capillary leak. Leaky vessels cause retinal edema and exudates. mehdijournal.com

9. Rapid fluid shifts around delivery. Changes in intravascular volume can temporarily worsen subretinal fluid. PMC

10. Oxidative stress. Reactive molecules injure vascular endothelium and RPE. mehdijournal.com

11. Imbalance of angiogenic factors (↑sFlt-1, ↓PlGF). This drives endothelial dysfunction and links eye changes to placental disease. PMC

12. Renal dysfunction. Toxin buildup and pressure swings worsen vascular reactivity. preeclampsia.org

13. Liver involvement. In HELLP, severe inflammation and coagulation changes amplify eye ischemia/bleeding risk. PMC

14. Persistent severe hypertension after delivery. Postpartum crises can still harm the retina/choroid. Lippincott Journals

15. Associated PRES. Brain edema can compound visual disability even if retinopathy is mild. Lippincott Journals

16. Retinal capillary occlusion (rare). Extreme vasospasm or clots can occlude small vessels. NCBI

17. Purtscher-like microembolization (rare). Complement activation and leukocyte clumps can injure the retina. PMC

18. Anemia/hemoconcentration. Oxygen delivery fluctuations aggravate ischemia. mehdijournal.com

19. Blood pressure lability. Wide swings, not only absolute numbers, strain vascular autoregulation. NCBI

20. Background hypertensive disease. Chronic hypertension raises the baseline risk for retinal injury during pregnancy crises. IJCE Ophthalmology

Symptoms

1. Blurry vision that can start suddenly.

2. Dark spots (scotomata) in part of the vision.

3. Flashes of light (photopsia).

4. Distorted lines (straight lines look wavy).

5. A gray curtain or water-wave effect if fluid lifts the retina.

6. Poor contrast (things look washed out).

7. Faded colors, especially reds.

8. Halos around lights.

9. Patchy missing areas in side vision.

10. Temporary vision loss in one or both eyes.

11. Headache along with vision changes (a red flag in pregnancy).

12. Eye strain despite a normal glasses prescription.

13. Sensitivity to light (photophobia).

14. Poor night vision while symptoms are active.

15. Sudden severe loss of vision when PRES or Purtscher-like retinopathy overlaps. NCBIBMJ Case Reports

Diagnostic tests

A) Physical exam

1. Accurate blood pressure measurement (repeat and compare).
   High readings confirm the systemic trigger. Severe hypertension pushes clinicians to act immediately to protect the eye and brain. preeclampsia.org

2. Basic neurologic check (mental status, reflexes, gait).
   This screens for PRES or other brain involvement that can also cause visual loss. Lippincott Journals

3. External eye and eyelid exam.
   Looks for lid edema and ocular surface issues but, more importantly, prepares for a careful retinal assessment.

4. Pupil exam for a relative afferent pupillary defect (RAPD).
   A subtle RAPD can signal asymmetric retinal or optic-nerve dysfunction even when the eye looks clear.

B) “Manual” bedside eye tests

5. Visual acuity with pinhole.
   Checks how much blur is from the retina versus the optics. Pinhole reduces lens/cornea blur and isolates retinal causes.

6. Confrontation visual fields.
   Simple mapping can detect field cuts from retinal detachment patches or PRES-related occipital problems.

7. Amsler grid at near.
   Wavy, broken, or missing lines point to macular edema or serous elevation.

8. Color vision (Ishihara plates or desaturation test).
   Color loss helps flag macular or optic nerve compromise.

9. Handheld direct ophthalmoscopy.
   A quick bedside look can catch hemorrhages, cotton-wool spots, or a shallow detachment before full imaging.

C) Laboratory & pathologic tests

10. Complete blood count with platelet count.
    Low platelets raise bleeding risk and suggest HELLP; white/red cell changes hint at inflammation or hemolysis. preeclampsia.org

11. Peripheral blood smear.
    Finding schistocytes supports microangiopathic hemolysis (HELLP). PMC

12. Liver enzymes and LDH (AST/ALT/LDH ± bilirubin).
    High AST/ALT and very high LDH fit HELLP and correlate with endothelial injury. PMC+1

13. Kidney function and uric acid (creatinine, BUN, uric acid).
    Worsening numbers mark severe disease and accompany retinal/choroidal injury. Medscape

14. Urine protein quantification (protein/creatinine ratio or 24-hour protein).
    A P:C ratio ≥0.3 or ≥300 mg/24 h supports the diagnosis when hypertension is present. ACOG

15. Coagulation tests (PT, aPTT, fibrinogen, D-dimer).
    Detects coagulopathy or DIC that can complicate retinopathy. Medscape

16. sFlt-1/PlGF ratio (where available).
    This FDA-cleared blood test helps risk-stratify hospitalized patients with hypertensive pregnancy disorders and can guide urgency; it supports, but does not replace, clinical diagnosis. preeclampsia.org

D) Electrodiagnostic tests

17. Electroretinography (ERG; full-field or multifocal).
    Measures electrical responses from the retina. It helps document retinal function during or after an ischemic episode. NCBIStatPearls

18. Visual evoked potential (VEP).
    If vision is poor but the fundus is relatively quiet, VEP checks the visual pathway to the brain and helps separate retinal from cortical (PRES) causes. NCBI

E) Imaging tests

19. Optical coherence tomography (OCT).
    Shows cross-sectional retinal and choroidal structure, detects subretinal fluid, macular edema, and choroidal thickening—key features in eclampsia-related detachment. PMC

20. Optical coherence tomography angiography (OCTA).
    Maps capillary flow without dye and can reveal choriocapillaris flow voids even when the fundus looks normal. This is especially useful during pregnancy since it avoids intravenous dye. PMC

Dietary “molecular” supplements

Supplements do not treat acute eclampsia or retinal detachment. Food-first is best. Use supplements only if your clinician recommends them for your diet and labs, especially in pregnancy. Office of Dietary Supplements

1. Calcium
   Dose: In settings with low dietary calcium, WHO recommends 1.5–2.0 g/day (split doses) during pregnancy to reduce the risk of hypertensive disorders.
   Function/Mechanism: Helps blood-vessel tone and reduces vasoconstriction sensitivity. WHO AppsNCBIWorld Health Organization

2. Vitamin D
   Dose: When deficiency is documented, 1,000–2,000 IU/day is commonly considered safe in pregnancy.
   Function/Mechanism: Supports calcium balance, immune modulation, vascular health. Do not exceed clinician guidance. ACOGPMC

3. Omega-3 DHA
   Dose: Many groups advise ≥200 mg DHA/day from food or supplements.
   Function/Mechanism: Anti-inflammatory lipids that support retina and vascular function; safe in pregnancy when sourced wisely. PMCAJOG MFM

4. Lutein + Zeaxanthin
   Dose: Prenatal-study doses similar to AREDS2 amounts have been well-tolerated; use only under clinician guidance.
   Function/Mechanism: Antioxidant carotenoids concentrated in the macula; support retinal pigment epithelium health. Evidence for pregnancy outcomes is emerging. PMCScienceDirect

5. Choline
   Function: Supports fetal brain development; may aid membrane signaling.
   Dose: Often included in prenatal vitamins; follow your prenatal’s label.

6. Folate (folic acid or methylfolate)
   Function: DNA synthesis; prevents neural tube defects; overall vascular health.
   Dose: Per prenatal vitamin; start pre-conception when possible.

7. Iron (if iron-deficient)
   Function: Corrects anemia that can worsen fatigue and headaches.
   Dose: Based on ferritin/hemoglobin and clinician plan.

8. Magnesium (dietary, not IV treatment)
   Function: Smooth-muscle relaxation and nerve function; not a replacement for magnesium sulfate therapy.
   Dose: From food first; supplement only if your clinician advises.

9. Potassium-rich foods
   Function: Helps BP control when kidneys are normal (bananas, oranges, beans).
   Caution: Only as advised—some conditions require potassium restriction.

10. General prenatal multivitamin
    Function: Fills common gaps (iodine, B12, etc.) without megadoses.
    Mechanism: Supports overall maternal tissue recovery and fetal needs. Office of Dietary Supplements

Regenerative,” and “stem cell drugs

Right now, there are no approved “immunity-booster drugs,” no stem-cell drugs, and no regenerative medicines recommended to treat eclampsia-associated retinopathy during pregnancy. Using unproven agents could harm mother and fetus and delay the real, life-saving care (magnesium sulfate, antihypertensives, and timely delivery). Because these approaches are experimental or inappropriate in pregnancy, I cannot provide drug names or dosages for them. Safer, evidence-based care is available—and it works in most cases. preeclampsia.orgPubMed

To be transparent, researchers study mechanisms like anti-angiogenic factors (e.g., sFlt-1), endothelial dysfunction, and choroidal ischemia, but these are not therapies you can take at home, and none are standard obstetric/ophthalmic treatments for this condition in pregnancy. If someone offers “stem cell” or “immune booster” injections for preeclampsia eye disease, seek a second opinion immediately.

Procedures/surgeries

Most patients do not need eye surgery. Vision typically improves after BP control and delivery. The steps below are uncommon and used only for selected complications. PMC

1. Induction of labor
   What/Why: Start labor with medicines or methods when it’s safer to deliver. This is the definitive step to end the disease process from the placenta. AAFP

2. Cesarean delivery (C-section)
   What/Why: Surgical delivery when rapid delivery is required or induction is unsafe/unsuccessful (maternal or fetal indications).
   Eye link: Removing the placenta ends the driver of vascular stress.

3. Laser photocoagulation (retina) — rare in this setting
   What/Why: If a specific bleeding/ischemic retinal lesion threatens vision postpartum, a retina specialist may use focal laser to seal or stabilize it.
   Mechanism: Laser creates tiny spots to reduce leakage or stabilize tissue.

4. Pars plana vitrectomy
   What/Why: Eye surgery to clear non-resolving vitreous hemorrhage or repair some complicated detachments after pregnancy.
   Mechanism: Removes the gel and blood to restore clarity and permit repairs.

5. Scleral buckle or vitrectomy for rhegmatogenous retinal detachment
   What/Why: If a true retinal tear/detachment develops (rare), surgery reattaches the retina to prevent permanent vision loss.
   Note: Most eclampsia-related detachments are serous and resolve without surgery. AAO

Practical preventions and protections

1. Early and regular prenatal care – detect rising BP and protein early.

2. Know your numbers – learn to use a home BP cuff properly postpartum.

3. Low-dose aspirin only if your OB recommends (for high-risk patients; prevention, not treatment).

4. Adequate calcium intake where diet is low (food first; supplement per clinician). World Health Organization

5. Healthy weight, activity, and sleep – support vascular health.

6. Control chronic conditions – diabetes, kidney disease, autoimmune disease.

7. Spacing pregnancies and preconception checkups – optimize baseline health.

8. Avoid smoking, alcohol, and recreational drugs – they worsen BP and fetal risk.

9. Medication check – review all meds/supplements with OB for safety.

10. Postpartum vigilance – risk persists for weeks after delivery; return urgently for severe headache, vision changes, or BP spikes. PMC

When to see a doctor

• Right now (ER): Vision suddenly gets blurry, you see flashes, dark spots, or you lose part of your visual field; you have severe headache, BP ≥160/110, shortness of breath, or seizure. PubMed

• Urgent clinic/triage: Any new or worsening visual symptoms in the third trimester or the first 6 weeks postpartum. PMC

• Routine follow-up: Eye exam and BP check after discharge to confirm improvement. AAO

What to eat” and “what to avoid

What to eat (focus foods):

1. Calcium-rich foods when your usual diet is low in calcium (milk, yogurt, cheese, tofu set with calcium, small bony fish, leafy greens). World Health Organization

2. Fruits and vegetables of many colors for potassium, fiber, and antioxidants.

3. Whole grains and legumes for steady energy and vascular health.

4. Lean proteins (beans, lentils, eggs, poultry, fish low in mercury).

5. Omega-3 DHA sources (2 servings/week of low-mercury fish like salmon or sardines, or clinician-advised DHA supplement). PMC

What to limit/avoid:

1. High-mercury fish (swordfish, shark, king mackerel, tilefish).
2. Alcohol (avoid in pregnancy).
3. Excess caffeine (stay within OB guidance).
4. Ultra-processed, very salty snacks if they displace healthier foods (salt restriction by itself doesn’t prevent preeclampsia, but very salty junk foods can worsen swelling/bloating and crowd out nutrients).
5. Unpasteurized or unsafe foods (follow standard pregnancy food-safety rules).

Frequently asked questions

1. Will my vision go back to normal?
   Often yes—especially for serous retinal detachment—within days to weeks after BP is controlled and after delivery. A small number can have lasting changes, so follow-up matters. AAO

2. Do I need eye surgery?
   Usually no. The main treatments are magnesium sulfate, blood-pressure control, and delivery. Eye surgery is rare and only for special complications. preeclampsia.org

3. What BP numbers are dangerous in pregnancy?
   Severe is typically ≥160 systolic or ≥110 diastolic—this needs urgent treatment to prevent stroke and seizures. PubMed

4. Why does pregnancy hurt my eyes?
   High blood pressure and endothelial stress make eye vessels spasm or leak; sometimes the brain’s visual areas swell (PRES). Lippincott Journals

5. What is serous (exudative) retinal detachment?
   Fluid gathers under the retina from choroidal/RPE leakage. In eclampsia it’s uncommon and usually resolves after treatment. AAO

6. Can this happen after the baby is born?
   Yes. Postpartum preeclampsia and vision changes can appear or worsen in the first 6 weeks. Don’t ignore new symptoms. PMC

7. Is magnesium sulfate safe for my baby?
   It’s the standard of care to prevent seizures; teams monitor you closely for side effects and keep an antidote ready. The ObG Project

8. Which blood-pressure medicines are used in emergencies?
   Labetalol, hydralazine, or immediate-release nifedipine are first-line choices in most protocols. ilpqc.org

9. Will glasses help the blur?
   Glasses don’t fix the underlying cause. As the retina/brain recover and BP normalizes, vision usually clears. Eye doctors may adjust glasses later if needed.

10. Can vitamins cure this?
    No. Supplements can help general health (and calcium may reduce risk in low-intake populations), but they do not treat eclampsia. World Health Organization

11. Could I lose vision permanently?
    It’s uncommon, but possible—especially if treatment is delayed or if there’s severe ischemia. That’s why rapid care is vital. Lippincott Journals

12. Do I need special eye tests?
    An ophthalmologist may do dilated fundus exam and non-invasive imaging (OCT) to track fluid and recovery.

13. What about future pregnancies?
    You’ll be higher-risk next time, so early prenatal care is important. Your OB may consider low-dose aspirin if you meet criteria.

14. Can I breastfeed while on BP meds?
    Often yes with commonly used agents like labetalol or nifedipine, but confirm with your OB/pediatrician.

15. When should I go back to normal activities?
    After your team clears you and vision is steady. Start slowly; avoid driving until your vision is reliable.
