Association Between Prognosis of Acute Retinal Necrosis and Retinal Involvement

Area of Science:

• Ophthalmology
• Infectious Diseases
• Retinal Diseases

Background:

• Acute retinal necrosis (ARN) is a severe viral retinitis.
• Understanding the impact of initial disease extent on outcomes is critical for managing ARN.

Purpose of the Study:

• To describe clinical presentation and treatment of ARN.
• To evaluate complications and outcomes based on initial retinal involvement extent.

Main Methods:

• Retrospective review of 48 ARN patients.
• Categorization into two groups based on initial retinitis extent (1-2 quadrants vs. 3-4 quadrants).

Main Results:

• Wider initial retinal involvement (3-4 quadrants) correlated with poorer presenting and final visual acuity.
• Retinal detachment occurred significantly more often in patients with extensive initial involvement (66.7% vs. 9.1%).
• Optic disc pallor was also more frequent in the extensive involvement group (71.1% vs. 36.4%).

Conclusions:

• The extent of retinal involvement at ARN presentation significantly influences visual outcomes.
• Early diagnosis and prompt initiation of antiviral therapy are vital for improving patient prognosis.
