Shingles in the eye, also known as ocular shingles, is a painful condition caused by the reactivation of the varicella-zoster virus, which also causes chickenpox. It primarily affects the area around the eye and can lead to complications if not promptly treated. While shingles near the eye can be distressing, early diagnosis and intervention can prevent long-term damage. Let’s look at it in a little more detail!
What Is Shingles in the Eye?
When the varicella-zoster virus reactivates in the ophthalmic branch of the facial nerve, it results in shingles in the eye. This condition can affect the eyelid, conjunctiva, cornea, and other ocular structures. It typically starts as a painful rash or blisters and may progress to inflammation, vision loss, or scarring if untreated. While shingles can occur in any part of the body, ocular shingles are especially concerning due to the potential impact on vision.
But, how will you know if it’s shingles? Let’s look at the signs and symptoms of shingles in the eye.
Symptoms of Shingles in the Eye
The symptoms of shingles in the eye can vary but often include:
- Redness and swelling around the eye.
- A painful rash or blisters, typically on one side of the face.
- Sensitivity to light (photophobia).
- Blurred or decreased vision.
- A burning or tingling sensation before the rash appears.
- Watery eyes or eye discharge.
Who Is at Risk for Shingles in the Eye?
Certain factors increase the likelihood of developing ocular shingles. These include:
- Age: Older adults, especially those over 60, are more susceptible.
- Weakened immune system: Conditions like HIV, cancer, or immunosuppressive medications elevate risk.
- History of chickenpox: The virus can remain dormant for years and reactivate later in life.
- Stress or trauma: These factors can trigger the virus reactivation.
When to Seek Medical Attention?
It is crucial to seek medical care immediately if you notice symptoms of shingles in the eye, especially if you experience:
- Persistent pain or a rash near the eye.
- Swelling or redness that spreads quickly.
- Blurred or impaired vision.
- Sensitivity to light or unusual eye discomfort.
Prompt evaluation ensures proper treatment of shingles in the eye and reduces the risk of complications such as corneal scarring or vision loss.
Treatment for Shingles in the Eye
Effective treatment of shingles in the eye involves a combination of medications and supportive care to control the infection, manage symptoms, and prevent complications. These include:
- Antiviral medications: Drugs like acyclovir, famciclovir, or valacyclovir are prescribed to limit viral replication and speed up recovery.
- Pain management: Over-the-counter pain relievers or prescription medications can help alleviate discomfort.
- Steroid eye drops: These may be used to reduce inflammation in severe cases.
- Lubricating eye drops: Artificial tears can provide relief from dryness or irritation.
- Cold compresses: Applying a cool cloth can soothe the affected area and reduce swelling.
While there is no definitive cure for shingles in the eye, early treatment minimises complications and improves outcomes.
Self-Care and Lifestyle Tips
- Maintain a strong immune system through a balanced diet and regular exercise.
- Avoid touching or scratching the rash to prevent infection.
- Protect your eyes by wearing sunglasses if light sensitivity occurs.
- Get vaccinated with the shingles vaccine to reduce the risk of developing shingles near eyes.

Frequently Asked Questions
Shingles in the eye, or ocular shingles, is a serious condition that can lead to complications such as corneal scarring, glaucoma, or vision loss if untreated. Early diagnosis and treatment are critical to prevent long-term damage.
With proper antiviral treatment, shingles generally begin to improve within a few weeks. However, complete healing of the rash and other symptoms may take 4–6 weeks, depending on the severity.
Some eye damage caused by shingles, such as corneal scarring, can be managed or repaired with advanced treatments like surgery or therapeutic lenses. However, early intervention is essential to minimize permanent damage.
An optometrist can detect ocular shingles, but for the management of severe symptoms or complications, an ophthalmologist with expertise should be consulted.
Foods high in arginine, such as nuts, chocolate, and gelatin, may promote viral replication and are best avoided during an active shingles infection. Instead, focus on a diet rich in lysine (found in dairy, fish, and chicken) and immune-boosting foods like fruits and vegetables.
