Herpes Zoster Ophthalmicus

Herpes Zoster Ophthalmicus (HZO) is a condition caused by the reactivation of the varicella-zoster virus, which also causes chickenpox. When this virus reactivates, it can affect the eye and surrounding areas, leading to symptoms like pain, redness, and blisters on the forehead and around the eye. HZO can cause serious eye problems, including vision loss, if not treated promptly. It often occurs in people who have had chickenpox, particularly in older adults or those with weakened immune systems. Early diagnosis and treatment are crucial for preventing complications.
