Eye infection (herpes)

by ZimSeller Pharmacy 27 May 2020

Herpes eye infection, also known as ocular herpes, is a viral infection of the eye caused by the herpes simplex virus (HSV). This infection can affect various parts of the eye, leading to significant discomfort and potential vision problems if not treated promptly. This article provides a comprehensive overview of herpes eye infection, including its causes, symptoms, diagnosis, and treatment options.

Definition

Herpes eye infection refers to an infection of the eye caused by the herpes simplex virus (HSV-1 or HSV-2). The virus can infect different parts of the eye, including the eyelids, conjunctiva, cornea, and, in severe cases, the retina.

Causes

Herpes eye infection is caused by the herpes simplex virus, which can be transmitted through:

  1. Direct Contact:

    • Touching an active herpes sore on the lips or face and then touching the eyes.
  2. Autoinoculation:

    • Spreading the virus from one part of the body to another, such as from a cold sore to the eye.
  3. Reactivation of Dormant Virus:

    • The virus can lie dormant in the body and reactivate later, especially during periods of stress, illness, or immunosuppression.

Symptoms

Common symptoms of herpes eye infection include:

  1. Eye Pain:

    • Persistent or severe pain in one or both eyes.
  2. Redness:

    • Red or bloodshot eyes, particularly around the cornea.
  3. Blurred Vision:

    • Difficulty focusing or seeing clearly.
  4. Tearing:

    • Excessive tearing or watery discharge from the eyes.
  5. Sensitivity to Light:

    • Increased sensitivity to light (photophobia).
  6. Eye Sores or Blisters:

    • Small, painful blisters on the eyelids or around the eyes.

Diagnosis

Diagnosing herpes eye infection involves several steps:

  1. Medical History and Symptom Review:

    • Discussing the onset, duration, and nature of symptoms with a healthcare provider.
  2. Eye Examination:

    • Slit-Lamp Examination: Using a special microscope to examine the eye in detail.
    • Staining Tests: Applying a dye (fluorescein) to highlight corneal damage.
  3. Laboratory Tests:

    • Viral Culture: Collecting a sample of eye discharge to test for HSV.
    • Polymerase Chain Reaction (PCR): Detecting HSV DNA in eye fluid samples.
  4. Imaging Tests:

    • Optical Coherence Tomography (OCT): Imaging to assess the retina and optic nerve if deeper infection is suspected.

Treatment

Treatment for herpes eye infection focuses on managing symptoms and preventing complications:

  1. Antiviral Medications:

    • Topical Antiviral Eye Drops/Ointments: Such as trifluridine, ganciclovir, or acyclovir.
    • Oral Antiviral Drugs: Such as acyclovir, valacyclovir, or famciclovir.
  2. Corticosteroids:

    • Used under strict supervision to reduce inflammation, typically in combination with antiviral treatment.
  3. Pain Relief:

    • Over-the-counter pain relievers or prescribed medications for severe pain.
  4. Supportive Care:

    • Using artificial tears to relieve dryness and discomfort.

Complications

Potential complications of herpes eye infection include:

  1. Corneal Scarring:

    • Leading to permanent vision impairment or blindness.
  2. Recurrent Infections:

    • Frequent recurrences can cause cumulative damage to the eye.
  3. Secondary Bacterial Infections:

    • Bacterial infection can complicate the primary viral infection.
  4. Glaucoma:

    • Increased eye pressure leading to optic nerve damage.

Prevention

Preventing herpes eye infections involves:

  1. Good Hygiene:

    • Avoid touching the eyes with unwashed hands, especially after touching cold sores.
  2. Avoiding Contact with Infected Individuals:

    • Minimizing direct contact with individuals who have active herpes sores.
  3. Managing Stress and Health:

    • Reducing stress and maintaining overall health to prevent reactivation of the virus.
  4. Regular Eye Check-Ups:

    • Especially for individuals with a history of herpes eye infections.

When to See a Doctor

Seek medical attention if experiencing:

  • Persistent eye pain or discomfort.
  • Sudden changes in vision, such as blurriness or vision loss.
  • Redness or swelling around the eye.
  • Any sores or blisters on the eyelids or around the eyes.

Coping and Support

Living with herpes eye infection involves:

  1. Education:

    • Learning about the condition and how to manage symptoms effectively.
  2. Support Groups:

    • Connecting with others who have similar experiences for emotional support.
  3. Stress Management:

    • Techniques such as mindfulness, meditation, or yoga to reduce stress levels.

Conclusion

Herpes eye infection is a serious condition that requires prompt diagnosis and treatment to prevent complications and preserve vision. If you suspect you have a herpes eye infection, consult with a healthcare provider for an accurate diagnosis and appropriate treatment plan.

In summary, understanding the causes, symptoms, and treatment options for herpes eye infections can help individuals manage this condition effectively and maintain good eye health.
