Insights
Systemic hypertension is a major risk factor for central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO). Diagnostic tools like transthoracic echocardiography and carotid Doppler are crucial for identifying embolic sources in CRAO.
Area of Science:
- Ophthalmology
- Cardiology
- Vascular Medicine
Context:
- Central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) are serious vascular events affecting vision.
- Identifying systemic risk factors and diagnostic tools is crucial for managing these conditions.
Purpose:
- To determine systemic risk factors for CRAO and CRVO.
- To evaluate the diagnostic utility of systemic investigations in CRAO and CRVO patients.
Summary:
- Retrospective chart review of 80 patients (38 CRAO, 42 CRVO) included systemic diagnostics such as blood pressure, cholesterol, carotid Doppler, transthoracic echocardiography (TTE), and thrombophilia screening.
- Systemic hypertension was prevalent in both CRAO (76.3%) and CRVO (75.6%) patients.
- Abnormal cardiac findings were more frequent in CRAO (61%) than CRVO (22%), while abnormal carotid findings were also higher in CRAO (44.1%) versus CRVO (9.5%).
- Thrombophilic factors were present in approximately 15% of patients in both groups.
Impact:
- Transthoracic echocardiography (TTE) and carotid Doppler are valuable for diagnosing embolic sources in CRAO.
- These tools are less frequently diagnostic for CRVO.
- Thrombophilia screening is recommended in younger patients or those lacking common risk factors.
- Adequate control of systemic hypertension is essential for managing CRAO and CRVO.
Objective:
The aim was to determine systemic risk factors for acute central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) and to evaluate the usefulness of systemic diagnostics in CRAO and CRVO.
Methods:
The study consisted of a retrospective chart review including 80 patients (CRAO 38, CRVO 42). All patients underwent systemic diagnostics including blood pressure measurement, blood cholesterol level, carotid Doppler imaging, transthoracic echocardiography (TTE), intraocular pressure measurement, glaucoma history and presence of thrombophilic factors. A systemic medical history was obtained.
Results:
Systemic hypertension was found in 76.3% CRAO and 75.6% CRVO patients. Abnormal cardiac findings were detected in 61% (CRAO) and 22% (CRVO). Abnormal carotid findings were detected in 44.1% for CRAO and 9.5% for CRVO. Pathological thrombophilic factors were found in both groups for approximately 15%.
Conclusions:
TTE and carotid Doppler are important tools in the diagnosis of sources of emboli in patients with CRAO, while for CRVO abnormal findings are revealed by TTE and carotid Doppler less often. Thrombophilia should be ruled out in the absence of common risk factors, especially in younger patients and systemic hypertension should be adequately controlled.
