Acute retinal necrosis syndrome is an eye disease caused by viral infections (mainly varicella-zoster virus and herpes simplex virus infections) resulting in damage to retinal tissues, which progresses rapidly and has an aggressive onset and can recover well if timely and adequate antiviral treatment is given at an early stage, otherwise the prognosis for vision is poor. Can acute retinal necrosis be cured? There is a possibility of cure, and some patients can fully recover their vision before the onset of the disease, but only if the diagnosis is confirmed at an early stage of the disease. Clinically, the lack of intraocular fluid examination results often deters the diagnosis, and wrong glucocorticoids or simple immunosuppressive treatment are given, resulting in most patients with the disease ending up with vision below 0.1. What are the symptoms of acute retinal necrosis? Patients usually have an insidious onset and often present with unilateral (mostly, sometimes successively bilateral) eye redness, eye pain, periorbital pain, irritation or foreign body sensation, and some patients usually complain of blurred vision and dark shadows in front of the eyes. How to treat acute retinal necrosis? Patients with suspected acute retinal necrosis can undergo anterior chamber aspiration and PCR testing for atrial herpes simplex virus and varicella zoster virus. After diagnosis is confirmed, antiviral treatment is administered, usually by antiviral infusion, intraocular injection and oral antiviral medication, and surgery is considered depending on comorbidities.
