6 Most Common Reasons For Vision Changes After Pregnancy

✔ Research-backed

Most women would agree that there are numerous transformations in one’s body after delivering a baby. Vision changes after pregnancy could also be added to this list. Due to a myriad of bodily changes a woman experiences during and after pregnancy, some physical changes occurring in the internal systems could lead to changes in the vision of a new mother. In addition, there may be a little discomfort for women who face vision dizziness, which may impact their usual routines. Keep reading this post as we tell you about some possible reasons, signs, and management of vision abnormalities in women post-delivery (1).

Causes Of Vision Changes After Pregnancy

Due to the hormonal changes in the internal system, the mother may experience problems of blurry vision or dizziness. Some of the effective causes of the vision change may include:

1. Blurred vision

After childbirth, the fluid retention capacity of the eye ducts are extremely hampered. As a result, the cornea cannot sustain its normal shape, and the vision may get blurred or highly distorted.

Heather Darroch, a mother to a baby girl, discusses her pregnancy-induced shift from long-sightedness to short-sightedness, “Pre-pregnancy, I was long-sighted, so I could see far away and had really good vision. I got pregnant and started to notice some changes in my vision. I booked the eye test and found out that I had a myopic shift. The doctor said it’s probably due to the pregnancy hormones. I had Rosy (her daughter) and breastfed for almost a year and noticed that my eyes weren’t getting any better. I had been getting a lot more migraines. I went for an eye test and got to know that my right eye has become more short-sighted than my left eye, so I think they are about the same, but my right eye deteriorated; so actually, pregnancy has completely changed my eyesight (i).”

Corneal edema is another condition that may affect normal vision. The cornea thickens as a result of corneal edema, and this thickening can cause changes in the curvature of the cornea, which tends to peak in late pregnancy but typically resolves after childbirth and cessation of breastfeeding. The swelling associated with corneal edema can affect the thickness and refractive index of the cornea, leading to changes in how light is focused on the retina, ultimately influencing vision (2).

2. Preeclampsia

Women suffering from high blood pressure issues may encounter preeclampsia. In such cases, the mother may suffer from vision problems, including light sensitivity or blurry vision and retinal detachment. It is highly recommended to consult your gynecologist and take the requisite medications for effective treatment.

Visual disturbance due to pre-eclampsia is common, but complete vision loss is rare, with an incidence of one to three percent (11).

According to Dr. Rohit Adyanthaya, MD, Assistant Professor of Ophthalmology, Eastern Virginia Medical School, Norfolk, “Patients who develop preeclampsia and eclampsia can have decreased vision from damage to the blood vessels in the retina. The most common retinal exam finding in this condition is constriction or spasm of retinal vessels, but there could also be hemorrhagesiHeavy discharge of blood from blood vessels and swelling of the retina, which can lead to decrease in vision. The retinal swelling can sometimes be very severe, to cause exudative retinal detachmentiCondition caused by fluid build-up behind the retina , which can cause significant loss of vision.

Rarely increased blood pressure can damage the part of the brain (occipital cortex), which is responsible for vision, and this is called cortical blindness.”

3. Gestational diabetes

The percentage of blood sugar level may fluctuate during and after the pregnancy phase. Overt diabetesiWhen women without diabetes exhibit elevated blood sugar content and meet all the criteria for diabetes in the first antenatal visit (preexisting diabetes) is more dangerous than gestational diabetesiA temporary condition in which a woman is diagnosed with diabetes for the first time during pregnancy mellitus for eye health.. Such changes of blood sugar level may harshly damage the small blood vessels attached to the eye retina. Thus, a temporary form of diabetes known as gestational diabetes occurs in this phase of gestation, and this can often hamper the eyesight, and the mother may suffer from blurry vision (3). According to the Centers for Disease Control and Prevention (CDC), gestational diabetes affects about two to 10% of pregnancies in the US, each year. Pregnancy induced diabetes may also increase the risk for dry eye syndrome.

Dr. Adyanthaya adds, “Pregnancy can worsen diabetic retinopathy, wherein there is leakage of blood from the retinal blood vessels due to diabetes. This can cause significant vision loss if not treated promptly.”

4. Pregnancy-induced hypertension (PIH)

Sometimes women do stress out in their pregnancy phase and suffer from the problems of gestational hypertension after their childbirth. It can often lead to abnormal vision changes (4).

5. Obstructive sleep apnea (OSA)

OSA is characterized by pauses in breathing during sleep due to the temporary collapse of the upper airway (5). In the postpartum period, hormonal fluctuations and weight changes may increase the risk of developing OSA. When OSA occurs, it can lead to decreased oxygen levels in the body, affecting various organs, including the eyes. The eyes rely on a consistent oxygen supply for optimal function, and reduced oxygen levels may impact the delicate structures involved in vision (6).

6. Pituitary adenoma

Mothers rarely encounter the problem of Pituitary adenoma. But in some rare cases, a tumor growth occurs in the pituitary gland of the women’s body. They inhibit the normal functioning of the hormonal secretion within the body, which can further lead to vision problems after pregnancy.

protip_icon Experts say
According to the European Society of Endocrinology, “Some pituitary adenomas also enlarge during pregnancy, and there is a risk of visual impairment, especially in women with macroadenomas or tumors near the optic chiasm (12).” The chiasm is a part of the brain where optic nerves cross.

Symptoms of Vision Changes After Pregnancy

Some of the common symptoms of postpartum eye problems, normally experienced may include:

  1. Dizziness
  2. Double vision
  3. Light sensitivity
  4. Eye strain and headaches or migraines
  5. Intermittent blur
  6. Appearance of flashing lights
  7. Temporary loss of vision

Treatment Of Vision Problems Experienced After Pregnancy

Vision changes encountered after the childbirth usually persists for six-eight months. During the pregnancy phase, contact lens users are often recommended to switch to normal glasses for their pregnancy phase. Some of the treatment or curative measures to cure vision problems after pregnancy may include:

1. Treatment of dry eyes

The problem of dry eyes can simply treated by utilizing the saline solution, which is normally used by the contact lens users. You can also contact an experienced ophthalmologist, who can prescribe effective eye drops or artificial tears to cure the vision problems (7).

2. Treatment Of Blurred Vision

If the condition of blurred vision persists for more than ten months after the childbirth, you can consult the ophthalmologist. He can further recommend LASIK laser eye surgery or new contact lenses for your eyes.

You can manage blurred vision caused by eye puffiness by applying cold compresses. Splash cold water over the face, stay hydrated, and limit sodium and caffeine intake.

3. Treatment Of Preeclampsia

Problems of preeclampsia can be effectively treated by taking prescribed medications like oral antihypertensive (nicardia, labetalol) and timely delivery.

4. Treatment of gestational diabetes

All these effective treatments and prescribed medications can help mothers to get rid of their vision problems after pregnancy.

Frequently Asked Questions

1. How long after pregnancy does vision return to normal?

Vision changes that occur during pregnancy usually resolve within a few weeks or months of childbirth (8).

2. Can pregnancy cause permanent vision changes?

Pregnancy-related vision changes are generally temporary and return to normal after delivery (9). However, consult your doctor in case of any discomfort and if the changes persist for longer than they should.

3. What are the long-term effects of vision changes during pregnancy?

Vision changes during pregnancy can often be temporary and have no lasting effects. However, it is critical to see an eye doctor for a thorough examination and to rule out any underlying conditions (8). Underlying conditions, such as gestational diabetes and preeclampsia, can have long-term adverse effects if not managed properly.

4. How do hormones affect vision changes during pregnancy?

Hormonal changes during pregnancy cause fluid retention. The extra fluid causes several changes, such as decreased tear production, eye and cornea thickness changes, and increased pressure inside your eyes. It is these alterations that can affect vision during pregnancy (8).

5. How does pre-existing eye health affect vision changes during and after pregnancy?

Hormonal changes during pregnancy can cause blood pressure fluctuations and fluid shifts, adversely affecting pre-existing eye health issues or diseases. It is vital to consult with an eye care specialist to determine any potential impact and receive necessary treatment (10).

6. Is vision change during pregnancy more common in some women than others?

Vision changes during pregnancy vary from one woman to another, and some women may be more prone to experiencing them than others. Generally, vision changes during pregnancy affect only about 15% of pregnant women. If they do happen, they are usually harmless. It is essential to visit an eye care specialist to rule out any underlying medical conditions (10).

Vision changes after pregnancy can be infuriating. You may need to squeeze your eyes and strain them to read the fine prints you used to understand earlier. However, this is not a rare postpartum change. It is common among new mothers and can be controlled with suitable measures. But if you are experiencing dizziness accompanied by blurred vision, you must consult an optometry specialist for immediate professional care. The health of your eyes should be your top priority as it supports you till the very end. Lastly, try consuming green leafy vegetables that may improve your vision.
