Ozempic is a medication called semaglutide that was created and approved by the FDA in 2017 for the purpose of managing the blood sugar levels of individuals with type 2 diabetes. Many individuals who were prescribed Ozempic to help them manage their type 2 diabetes also experienced weight loss as an added benefit of the medication. The weight loss was significant enough that in June 2021, this same medication was approved for weight loss by the FDA under the name Wegovy.
This development is significant because there was a significant increase in the number of individuals who began to use semaglutide to help them lose weight. With the increase in people using the medication, there has also been an increase in reported side effects. One side effect that is particularly concerning has been Ozempic vision loss, also referred to as “Ozempic blindness.” Today we are going to discuss what this condition involves, how common it is, what to look for, whether it’s reversible, and what, if any, treatments are available.
What Is “Ozempic Blindness”?
In 2024, the results of a study published in JAMA Ophthalmology reported that some individuals taking semaglutide experienced Ozempic vision loss. There are three different serious eye issues that have been linked to semaglutide and Ozempic use. If you are using semaglutide and notice any sudden vision changes, it is very important to discontinue its use and see an eye doctor right away.
- Non-arteritic anterior ischemic optic neuropathy (NAION)
- This condition occurs when the optic nerve, which sends signals from the eye to the brain, does not get enough blood flow and can cause sudden vision loss that usually happens in one eye.
- Papillitis
- This is a condition involving swelling of the optic nerve where it connects to the eye and causes blurred vision, pain, and difficulty seeing clearly.
- Paracentral acute middle maculopathy
- This condition affects the central part of the retina and can cause dark spots, blurry vision, or difficulty seeing clearly.
How Common Is Ozempic Vision Loss?
These vision-related side effects are concerning, but fortunately, they are considered rare. In fact, these issues are so rare that doctors and researchers do not fully understand what causes them to happen. The majority of Ozempic users do not experience these serious vision problems, but it is important to be aware of the potential and what to do if they do occur.
How Will I Know If I Am Experiencing Ozempic Vision Loss?
When you begin to experience “Ozempic blindness,” you may notice several warning signs, and you should take them seriously because some can cause permanent vision loss and need immediate medical attention. Some of the warning signs of Ozempic vision loss include:
- Sudden blurry vision: Your vision may become noticeably blurry, making it difficult to read, drive, or see details clearly.
- Dark or blind spots: Some people develop a shadow or a dark area in their vision that may only affect one eye, starting out small and becoming gradually larger.
- Loss of peripheral vision: If you notice that it becomes harder to see objects out of the corners of your eyes, it may mean you are experiencing damage to your optic nerve.
- Flashing lights or distorted vision: Some may notice sudden flashes of light, wavy lines, or distortion, similar to the symptoms of a migraine aura.
- Eye pain or pressure: Intermittent discomfort, aching behind the eye, or a feeling of pressure can sometimes be a sign of developing issues.
- You may have only one affected eye: Both eyes may not be affected because conditions like NAION usually only affect one eye, but the other eye can also become affected later.
Does Blurry Vision From Ozempic Go Away?
You may have the question, “Can Ozempic cause temporary blindness?” The answer is sometimes, it depends on the specific condition that is affecting your vision. Blurred vision can be triggered by rapid changes in blood sugar levels, so this side effect is usually temporary and improves as these levels stabilize. Many people who begin taking medications like Ozempic that help to regulate blood sugar levels experience blurred vision that improves after three or four months.
Unfortunately, conditions like NAION can lead to permanent vision loss, and according to the American Academy of Ophthalmology, Ozempic has been linked to vision changes, including blurred vision and worsening of diabetic retinopathy. It is important to note that the JAMA study mentioned earlier did not prove that using semaglutide causes NAION, but it did show that individuals who used it were 4 times more at risk.
Are There Treatments Available To Repair Ozempic Vision Loss?
If you begin to experience vision changes while taking Ozempic, consult an eye care professional right away because there is a better chance of preventing permanent damage if the condition is detected early. Sometimes getting your blood sugar levels in check is enough to make blurry vision from Ozempic go away, but unfortunately, there are no treatment options for conditions like NAION, and the damage is usually permanent.
While “Ozempic blindness” is not a common side effect, it is important to be aware that these vision-related side effects are possible. If you are using semaglutide, make sure you are getting regular eye check-ups and give immediate attention to any vision changes so any issues you may have can be caught in the early stages to reduce the risk of permanent damage.
