Arterial insufficiencies: Central retinal artery occlusion

Area of Science:

• Ophthalmology
• Emergency Medicine

Background:

• Central retinal artery occlusion (CRAO) is a critical condition causing abrupt, painless vision loss.
• Prognosis for visual recovery in CRAO is generally poor, with vision loss often permanent.
• Numerous treatments have been attempted historically with limited success.

Purpose of the Study:

• To review the efficacy of various treatment modalities for CRAO.
• To highlight hyperbaric oxygen therapy as a potential treatment option.
• To provide guidance on optimizing treatment duration and utilization review.

Main Methods:

• Review of historical and current treatment strategies for CRAO.
• Analysis of factors influencing treatment response, including symptom severity and duration.
• Evaluation of hyperbaric oxygen therapy outcomes.

Main Results:

• Most treatments for CRAO have demonstrated minimal success over the past century.
• Hyperbaric oxygen therapy has shown some potential benefit.
• Patient stabilization typically occurs within days of symptom onset.

Conclusions:

• Hyperbaric oxygen therapy represents a notable exception among CRAO treatments.
• Optimal treatment duration is individualized based on patient response and clinical status.
• Utilization review is advised for prolonged treatments beyond three days post-plateau.
