Purpose
Acute retinal artery occlusion (RAO) is an urgent ophthalmic condition often indicative of future ischemic pathology. Patients diagnosed at an outpatient retina clinic must present to an emergency department (ED) or primary care clinic to obtain a systemic workup. We review the overall compliance and suspected delay in completing the required testing.
Design
Retrospective cohort study
Methods
Patients presenting with a symptomatic RAO from June 2009 to January 2019 at a vitreoretinal practice (The Retina Institute, St. Louis, MO) were included. Documentation of carotid vasculature and echocardiographic imaging was requested from the patient’s primary care physician (PCP), cardiologist, or neurologist. Time to workup (TTW) from RAO diagnosis to receiving appropriate workup and site of workup (ED vs. outpatient setting) were recorded.
Results
One hundred forty-seven patients were included. A total of 132 (89.8%) patients were documented as having completed at least one type of cardiovascular or carotid imaging. Seventy-seven patients (52.3%) were documented to have completed both carotid and echocardiographic imaging. Following RAO diagnosis, 97 (66.0%) patients were referred to an outpatient facility while 35 (23.8%) were evaluated at an ED. Mean TTW through an ED setting vs. outpatient was 2.20 days (1.10 STDM, range 0–29) vs.13.6 days (2.23 STDM, range 0–149) respectively (p=0.003).
Conclusion
Our study gives objective data to the delay suspected in referring patients with acute symptomatic RAO for outpatient workup. We recommend all outpatient ophthalmology and retina practices establish a relationship with a comprehensive or primary stroke center to facilitate urgent testing through an emergency department.
