Changes in your vision can be worrisome, particularly if they occur suddenly. If you experience any of these symptoms, don’t ignore them: one eye becomes blurred, colors seem duller or you feel pain when moving your eye. It might be something called optic neuritis, which is an inflammation of the optic nerve.
The optic nerve is like a communication pathway for your eye and the brain, it carries information that allows you to see. This nerve can become inflamed and thus hinder the transmission of the visual signals making changes in vision. “Optic neuritis can happen very quickly, and it can sometimes be associated with an underlying immune-related condition. Early diagnosis can help find the cause and get you the right treatment.
Optic neuritis is inflammation of the optic nerve which can block the transfer of visual signals from your eye to your brain. It commonly affects one eye. People may notice blurred or dim vision, reduced colour perception or pain, particularly when moving the eye. The symptoms can develop over a few hours to a couple of days. Optic neuritis can occur sometimes without a clear reason. In others, it may be associated with an autoimmune condition or infection.
There isn’t always one simple answer. Several conditions or factors can trigger inflammation of the optic nerve.
Optic neuritis is a disease caused mainly by an abnormal immune response. Instead of protecting the body, the immune system attacks the protective covering of the optic nerve. Optic neuritis is usually associated with Multiple Sclerosis (MS) involving the brain and spinal cord. In some people, optic neuritis may be the first noticeable sign of MS.
Some viral infections, including measles, mumps and influenza, as well as certain bacterial infections, can trigger inflammation of the optic nerve. In some cases, the inflammation develops after the infection has already settled.
There are also other conditions like Neuromyelitis Optica (NMO) which can affect the optic nerve and can cause more severe or repeat episodes of optic neuritis.
Rarely, certain medications or harmful substances may affect the optic nerve.
In a significant number of cases, however, no definite cause is found. Even then, follow-up is important because an underlying condition may become visible later.
The symptoms can vary from person to person, but they often develop relatively quickly. Common symptoms include:
Symptoms may become worse over a short period and then stabilise. Vision often begins to improve gradually over the following weeks, although recovery can take longer depending on the severity and underlying cause.
There are many causes of vision changes and the diagnosis of Optic Neuritis depends upon careful evaluation. Your ophthalmologist will discuss your symptoms and medical history and then do a full eye exam. Including checking:
Depending on your symptoms and examination findings, other tests may be recommended.
MRI of the brain and orbit can give detailed images of the optic nerve and surrounding structures. It can also assist in identifying changes that may be related to conditions such as Multiple Sclerosis.
Sometimes blood tests may be suggested to look for infections, immune-related conditions or specific antibodies connected with diseases like Neuromyelitis Optica.
Optical Coherence Tomography (OCT) can be used to measure the retinal nerve fibre layer and to follow changes over time. A Visual Evoked Potential (VEP) test looks at the speed of visual signals from the eye to the brain, and can help determine if the optic nerve is involved.
The exact tests required depend on the individual patient’s symptoms and clinical findings.
Treatment depends on the severity of the condition and importantly the underlying cause.
In some mild cases, immediate treatment may not be necessary. Vision can begin improving naturally over several weeks. Regular follow-up remains important to monitor recovery.
The doctor might suggest corticosteroids to reduce inflammation of the optic nerve. They can be given by mouth or by intravenous treatment. Steroids may assist in speeding up visual recovery and reducing pain although they may not always alter the ultimate long-term visual prognosis.
When optic neuritis is linked to an autoimmune condition such as Multiple Sclerosis or Neuromyelitis Optica, treatment may also be required for the underlying disorder to reduce the risk of future episodes.
For severe or recurrent cases that do not respond adequately to corticosteroids, plasma exchange (plasmapheresis) may sometimes be considered.
Supportive care, visual aids when required and regular follow-up may also help patients manage their daily activities during recovery.
Some may have a second episode, particularly if the optic neuritis is related to an underlying autoimmune disease. This is one reason not to ignore follow-up even if the vision improves. If you notice another episode of vision loss, colour changes or pain with eye movement, consult an eye specialist promptly rather than waiting for the symptoms to settle on their own.
Sudden or unexplained changes in vision deserve professional attention. If you develop vision loss, blurred or dim vision in one eye, pain when moving the eye or colours suddenly appearing duller, arrange an eye examination.
It is particularly important not to assume that these symptoms are simply due to tired eyes or prolonged screen use. There are many eye and nerve problems that can cause similar symptoms. It is important to find the cause so you can be treated properly.
If you see sudden changes in your vision a check up with an eye doctor will help you to know what is going on with your sight and if it needs further tests. Ojas Maxivision Eye Hospital has a dedicated team of eye specialists who provide advanced eye care services. The Ojas Maxivision team includes specialists across areas such as retina, cataract, glaucoma, cornea and refractive surgery.
If you are experiencing unexplained vision changes, don’t wait and hope they disappear. Timely evaluation can make the difference between simply monitoring a problem and identifying a condition that needs treatment.
Early evaluation is always the wiser choice.
