Progress in central retinal artery occlusion: a narrative review

Area of Science:

• Ophthalmology
• Vascular Medicine

Background:

• Central retinal artery occlusion (CRAO) is an ophthalmic emergency causing significant vision loss.
• Understanding CRAO epidemiology and pathophysiology is crucial for timely intervention and improved prognosis.

Purpose of the Study:

• To review recent advancements in Central retinal artery occlusion (CRAO) research.
• To explore updated knowledge on CRAO epidemiology, pathophysiology, examination, and treatment.

Main Methods:

• This narrative review synthesizes current literature on Central retinal artery occlusion (CRAO).
• Key areas examined include epidemiological data, pathophysiological mechanisms, diagnostic methods, and therapeutic strategies.

Main Results:

• CRAO research has yielded new insights into its characteristics and mechanisms.
• Treatment options are evolving, with emerging interest in pars plana vitrectomy plus endovascular surgery.
• Distinguishing treatment effects from natural disease progression in CRAO subclasses is essential.

Conclusions:

• Significant progress has been made in understanding Central retinal artery occlusion (CRAO).
• While surgical interventions show promise, further research is needed to clarify their efficacy compared to conservative methods and the disease's natural course.
