Summary
An aggressive, systematic treatment approach for central retinal artery occlusion (CRAO) significantly improved vision in 73% of patients. Early intervention within 12 hours and identifying the cause are key for better outcomes in CRAO.
Area of Science:
- Ophthalmology
- Vascular Neurology
Background:
- Central retinal artery occlusion (CRAO) is a critical condition leading to sudden vision loss.
- Prompt and effective treatment is essential to restore retinal circulation and preserve visual function.
Purpose of the Study:
- To evaluate the efficacy of a systematic, aggressive treatment regimen for acute nonarteritic central retinal artery occlusion (CRAO).
Main Methods:
- A stepwise systematic treatment protocol was applied to 11 patients with acute CRAO (symptoms <48 hours).
- The regimen included ocular massage, vasodilators, diuretics, anterior chamber paracentesis, and thrombolytics.
- A control group of 5 patients received non-systematic treatment.
Main Results:
- The systematic regimen improved visual acuity and retinal circulation in 8 of 11 patients (73%).
- Successful outcomes were associated with symptom duration under 12 hours and specific embolic causes.
- No improvement was observed in the non-systematic treatment group (P = .01).
Conclusions:
- An aggressive, systematic approach combining medical and mechanical interventions can restore retinal circulation in CRAO.
- Prognosis is influenced by the cause of occlusion, embolic nature, and duration of ischemia.
- Further studies are needed to confirm effectiveness and prognostic factors.
