Central retinal artery occlusion

Extract

• The symptom is sudden, painless unilateral vision loss.
• To confirm the diagnosis, the patient must be sent immediately to an ophthalmic emergency department with a unit treating cerebrovascular emergencies (stroke unit).
• Central retinal artery occlusion is a form of acute cerebrovascular accident associated with a risk of retinal infarction and permanent vision loss.
• Irreversible retinal damage starts to occur as soon as 1½ hours after the occlusion.
• Time must not be lost inspecting the fundus (except for optical coherence tomography [OCT] at the ophthalmic emergency department).
• Intravenous thrombolytic therapy within 4½ h from symptom onset should be considered in the emergency stroke unit with individual consideration of risks and benefits.
• Mechanical interventions to dislodge the embolus, such as applying pressure to the eye or anterior chamber paracentesis are no longer recommended.
