What is herpes zoster ophthalmicus?

Herpes zoster ophthalmicus, also known as ocular shingles, is a disease caused by the varicella-zoster virus infecting ocular tissues, including the eyeball and its accessory structures. It commonly occurs in individuals who are physically weak, elderly, or immunocompromised. Symptoms of herpes zoster ophthalmicus vary and may include eyelid redness and swelling, pain, the appearance of clear or translucent blisters, and possible complications such as keratitis and iridocyclitis. Treatment primarily involves antiviral medications and corticosteroids, with additional attention required to prevent bacterial infection and ocular damage. The occurrence of this disease is closely associated with factors that reduce immune resistance, such as staying up late, exposure to cold, fatigue, and other triggers. Therefore, prevention should focus on improving physical condition and avoiding these triggering factors.
