At a Glance
Category
Detail
Condition
Chorioretinal diseases including age-related macular degeneration, central serous chorioretinopathy, and pathological myopia
Key Mechanisms
Non-invasive, full-field, high-temporal-resolution imaging of choroidal blood flow using laser Doppler flowmetry combined with digital holography to measure flow amplitude, directionality, and pulsatile dynamics
Target Population
Human participants with healthy eyes or eyes affected by chorioretinal diseases
Care Setting
Ophthalmology clinical and research settings requiring quantitative assessment of ocular hemodynamics
Key Highlights
LDH provides millisecond temporal resolution enabling assessment of pulsatile blood flow within a single cardiac cycle
LDH differentiates arteries from veins using flow waveforms and spectral data, offering quantitative hemodynamic parameters
Meta-analysis pooled mean choroidal artery diameter of 134.2 μm (95% CI: 128.3 to 140.1 μm) with low heterogeneity (I2 = 0)
Guideline-Based Recommendations
Diagnosis
Use LDH as a non-invasive imaging modality to assess choroidal blood flow and vascular anatomy
Employ LDH to differentiate arterial and venous circulation based on flow waveform and spectral characteristics
Management
Incorporate LDH for monitoring hemodynamic changes in chorioretinal diseases to inform clinical decision-making
Utilize LDH quantitative data to evaluate disease progression and response to therapy
Monitoring & Follow-up
Apply LDH for repeated, rapid assessments of choroidal blood flow dynamics and autoregulatory responses
Monitor pulsatile oscillations and flow heterogeneity across vascular beds using LDH
Risks
LDH is non-invasive and does not require dye injection, minimizing patient risk compared to fluorescein or indocyanine green angiography
Patient & Prescribing Data
Patients with healthy eyes and those with chorioretinal diseases requiring vascular assessment
LDH offers rapid, non-contact imaging that can guide diagnosis and management by providing detailed hemodynamic information without invasive procedures
Clinical Best Practices
Standardize LDH imaging protocols to ensure reproducibility and comparability across studies and clinical settings
Combine LDH with other imaging modalities for comprehensive structural and functional ocular assessment
Interpret LDH data considering normative reference values such as choroidal artery diameter for clinical context
AMD severity is measured on a spectrum, and the sooner doctors, patients, and caregivers are aware of its presence, the sooner everyone can work together to protect against it.
