INTRAVENOUS THROMBOLYTIC THERAPY FOR ACUTE NONARTERITIC CENTRAL RETINAL ARTERY OCCLUSION. A REVIEW
Summary
Intravenous thrombolysis shows promise for central retinal artery occlusion (CRAO), a type of ischemic stroke. Studies indicate a 45% visual acuity improvement with alteplase, with no significant adverse events, suggesting a safe and effective treatment option.
Area of Science:
- Ophthalmology
- Neurology
- Vascular Medicine
Background:
- Central retinal artery occlusion (CRAO) is an acute ischemic stroke with severe visual consequences.
- Current conservative therapies for CRAO lack proven efficacy.
- CRAO can indicate a higher risk of future cerebrovascular events.
Purpose of the Study:
- To review clinical studies on intravenous thrombolysis for CRAO.
- To evaluate the efficacy and safety of this treatment.
- To propose an optimal diagnostic and therapeutic algorithm for acute CRAO management.
Main Methods:
- Systematic review and meta-analysis of published clinical studies on intravenous thrombolysis in CRAO.
- Analysis of patient data regarding visual acuity improvement and adverse events.
- Evaluation of treatment outcomes within a 4.5-hour time window from symptom onset.
Main Results:
- Significant visual acuity improvement observed in 45% of patients treated with alteplase within 4.5 hours.
- No significant increase in adverse events reported within this therapeutic window.
- Intravenous thrombolysis appears effective and safe for acute CRAO management.
Conclusions:
- Intravenous thrombolysis is a potentially effective and safe treatment for central retinal artery occlusion.
- Further data from prospective randomized controlled trials are needed to confirm these findings.
- Specialized centers and urgent patient transfer are crucial for optimal CRAO management and secondary prevention.
