Summary

Early treatment of acute retinal necrosis (ARN) with intravenous acyclovir and laser photocoagulation shows promising results. Aggressive management of limited ARN can lead to a good visual prognosis and prevent vision loss.

Area of Science:

  • Ophthalmology
  • Virology

Background:

  • Acute retinal necrosis (ARN) is a severe viral retinitis known for progressive inflammation.
  • ARN often leads to complications like retinal detachment and poor visual outcomes.

Purpose of the Study:

  • To evaluate the efficacy of early, aggressive treatment for acute retinal necrosis.
  • To assess visual outcomes and complications in ARN patients treated with intravenous acyclovir and laser photocoagulation.

Main Methods:

  • Retrospective analysis of 12 consecutive ARN patients (13 eyes) with early-stage disease.
  • Treatment involved high-dose intravenous acyclovir and laser photocoagulation.
  • Follow-up ranged from 3 to 21 months.

Main Results:

Related Experiment Videos

  • Only 1 patient (8%) experienced retinal detachment and vision loss.
  • No cases of bilateral ARN occurred after initiating antiviral therapy.
  • Final visual acuity was 20/40 or better in 46% of eyes and 20/400 or better in 92%.

    • Conclusions:

    • Early detection and aggressive treatment of ARN, particularly with intravenous acyclovir, can significantly improve visual prognosis.
    • Limited disease extent at presentation is associated with better outcomes.
    • Timely intervention may prevent severe complications such as bilateral involvement and vision loss.
