Abstract:
Acute retinal necrosis (ARN) is a rare but devastating and rapidly progressive viral retinitis. The most common aetiological agents are reported to be herpes simplex virus (HSV) and varicella zoster virus. A boy in middle childhood presented with redness in his right eye for the last 3 days. A diagnosis of unilateral ARN was made after complete ocular examination. Systemic investigations were advised, and the patient was started on intravitreal and systemic antiviral therapy. An aqueous humour sample on PCR was positive for HSV I and II, thereby confirming the diagnosis of ARN. Early diagnosis and management helped in achieving optimal visual and anatomical results.
Insights
Acute retinal necrosis (ARN), a severe viral eye infection, was diagnosed in a child. Early treatment with antiviral therapy led to positive visual and anatomical outcomes.
Area of Science:
- Ophthalmology
- Virology
- Infectious Diseases
Background:
- Acute retinal necrosis (ARN) is a rare, rapidly progressive viral retinitis.
- Herpes simplex virus (HSV) and varicella zoster virus are common causes of ARN.
Purpose of the Study:
- To report a case of unilateral ARN in a middle childhood patient.
- To highlight the importance of early diagnosis and management of ARN.
Main Methods:
- Clinical ocular examination.
- Polymerase chain reaction (PCR) testing of aqueous humor.
- Intravitreal and systemic antiviral therapy.
Main Results:
- Diagnosis of unilateral ARN confirmed by PCR positive for HSV I and II.
- Successful treatment with antiviral therapy.
Conclusions:
- Early diagnosis and prompt management are crucial for optimal visual and anatomical outcomes in ARN.
- HSV I and II can cause ARN in children.
