Shingles: Symptoms, Effects, and Vision Concerns - Dermatology

More Info

Shingles, also known as herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox. It typically presents with a painful rash that can occur anywhere on the body, but it is most commonly found on one side of the torso. However, shingles can also affect the face, including areas around the eyes, which can lead to serious complications.

In your grandfather's case, the swelling near his nose and under his eyelid could indeed be related to shingles, especially if the dermatologist has diagnosed it as such. It's important to note that shingles does not always present with pain or itching, particularly in older adults or individuals with weakened immune systems. The absence of pain or itching does not rule out the possibility of shingles; some individuals may experience a milder form of the disease.

One of the significant concerns with shingles, particularly when it affects the facial area, is the potential for complications related to vision. When shingles occurs in the area around the eye, it is referred to as herpes zoster ophthalmicus. This condition can lead to serious eye problems, including:
1. Keratitis: Inflammation of the cornea, which can cause pain, redness, and blurred vision.

2. Uveitis: Inflammation of the uvea, which can lead to vision loss if not treated promptly.

3. Retinal complications: In some cases, shingles can lead to retinal damage, which may cause visual disturbances, such as seeing double (diplopia) or other vision problems.

The fact that your grandfather is seeing double could be a sign of ocular involvement, and it is crucial to have this evaluated by an eye care professional. Double vision can occur for various reasons, including muscle weakness or nerve involvement due to shingles.
If shingles is indeed affecting the area around the eye, it is essential to seek prompt medical attention. Treatment for shingles typically includes antiviral medications, which can help reduce the severity and duration of the infection if started early. Additionally, pain management may be necessary, even if your grandfather is not currently experiencing pain.

In summary, while the swelling near your grandfather's nose and under his eyelid may be related to shingles, the lack of pain does not exclude this diagnosis. The potential impact on vision, especially with the reported double vision, warrants immediate evaluation by an ophthalmologist. Early intervention is crucial to prevent complications that could lead to lasting vision problems. If shingles is confirmed, following the prescribed treatment plan and monitoring for any changes in vision will be essential for your grandfather's health and well-being.
