Introduction:
Acute retinal necrosis (ARN) is a severe eye disease demanding swift treatment to prevent blindness. Early action involving antiviral medications and corticosteroids is crucial for optimal visual outcomes.
Objective:
We present an ARN case series showcasing treatment experience and results.
Methodology:
Patients diagnosed with ARN based on SUN Working Group 2021 criteria were included; all underwent comprehensive eye exams, PCR analysis, and imaging.
Results:
Eight patients were studied; PCR confirmed ARN in six. Induction treatment, either oral valacyclovir (5/8) or intravenous acyclovir (3/8), lasted 10-14 days. Maintenance included oral valacyclovir (6/8), oral valganciclovir (2/8) for six months, along with intravitreal ganciclovir. Visual outcomes were similar for oral and intravenous therapies; poor baseline acuity and macular involvement tend to result in a worse final acuity.
Conclusions:
Swift treatment is vital to ARN management. Our findings emphasize effective treatment strategies' role in visual prognosis.
