Summary
Acute retinal necrosis (ARN) is a rare, vision-threatening viral eye disease. Early antiviral treatment is crucial, but vision loss can still occur, highlighting the need for prompt specialist care.
Area of Science:
- Ophthalmology
- Virology
- Retinal Diseases
Background:
- Acute Retinal Necrosis (ARN) is a rare but severe viral infection of the retina.
- Early diagnosis and treatment are critical for preserving vision.
Observation:
- This study documents three cases of ARN over one year at a district eye department.
- Patients presented with unilateral uveitis and were treated with systemic antivirals and corticosteroids.
Findings:
- Early treatment improved clinical findings and visual acuity in all patients.
- Despite treatment and pars plana vitrectomy in two cases, visual acuity decreased in some patients during follow-up.
- The specific viral pathogen (VZV, HSV, CMV) is less critical than prompt initiation of antiviral therapy.
Implications:
- ARN requires urgent virostatic treatment, followed by corticosteroids after 24-48 hours.
- Ophthalmologists should be aware of ARN's potential for vision loss even with treatment and consider referral to vitreoretinal specialists for complications.
- Patient education on prognosis and the risk to the contralateral eye is essential.
