Primary Care Management of Multiple Retinal Hemorrhages
Patients with multiple retinal hemorrhages found on ophthalmologic examination should be urgently referred to a stroke center or emergency department within 24 hours for comprehensive neurological evaluation, as these findings may represent an ocular stroke equivalent with high risk for concurrent cerebrovascular events. 1
Immediate Management
- Treat retinal hemorrhages as a potential medical emergency requiring prompt referral to an emergency department or stroke center, especially when multiple hemorrhages are present 2, 1
- Do not delay referral to obtain further outpatient evaluation or institute other treatments 1
- Establish communication with the ophthalmologist who made the finding to understand the specific type, location, and extent of the hemorrhages 2
- Determine if the patient has any symptoms of giant cell arteritis (GCA) if over 50 years old, including headaches, scalp tenderness, jaw claudication, or temporal tenderness 1, 3
Diagnostic Workup to Initiate or Coordinate
- Brain imaging with MRI and diffusion-weighted imaging should be performed urgently, as up to 24% of patients with retinal vascular events have concurrent silent brain infarctions 2, 1
- Vascular imaging to assess carotid artery status is essential, as clinically significant carotid stenosis is discovered in up to 70% of patients with symptomatic retinal vascular events 2, 1
- Order inflammatory markers (ESR, CRP) and complete blood count with platelets, especially if GCA is suspected 2, 3
- Evaluate for cardiovascular risk factors including hypertension, diabetes, and hyperlipidemia 2, 1
Etiology Assessment
- Retinal hemorrhages may indicate:
Ongoing Management After Initial Evaluation
- Implement secondary stroke prevention with antiplatelet therapy as recommended by neurology 1
- Optimize control of chronic systemic diseases (diabetes, hypertension, lipid disorders) 2, 1
- Provide smoking cessation counseling if applicable 2
- Ensure regular ophthalmologic follow-up to monitor for neovascular complications 2
Monitoring for Complications
- Watch for development of iris or retinal neovascularization, which may require panretinal photocoagulation (PRP) with or without anti-VEGF therapy 2
- Monitor for signs of neovascular glaucoma, which can result from new vessels growing on the iris and anterior chamber angle structures 2
- Be alert for visual changes that could indicate progression or complications 2
Important Considerations and Pitfalls
- The risk of stroke is highest within the first 7 days after retinal vascular events and remains elevated for 30 days 2, 3
- Do not assume that retinal hemorrhages are benign findings, even if the patient is asymptomatic 4
- Establish effective communication with the patient's ophthalmologist about the status of the retinal disease and its relation to systemic disease 2
- Remember that retinal vascular events are considered stroke equivalents by the American Heart Association 2
