Summary
Multimodal imaging reveals intraretinal macroaneurysms (IMs) are increasingly diagnosed. A simple classification system distinguishes primary IMs from secondary IMs based on coexisting posterior segment diseases.
Area of Science:
- Ophthalmology
- Medical Imaging
- Retinal Diseases
Background:
- Intraretinal macroaneurysms (IMs) are vascular abnormalities in the retina.
- Advancements in multimodal imaging techniques facilitate their detection.
- Standardized classification is needed for consistent diagnosis and understanding.
Purpose of the Study:
- To analyze the multimodal imaging characteristics of intraretinal macroaneurysms.
- To propose a simple classification system for IMs.
Main Methods:
- Intraretinal aneurysms >150 μm on fluorescein angiography were defined as IMs.
- IMs were categorized as primary (no coexisting posterior segment diseases) or secondary (with coexisting diseases).
- Multimodal imaging, including fluorescein angiography and optical coherence tomography, was utilized.
Main Results:
- Twenty IMs were observed in 18 patients (mean age 65.44 years).
- Mean IM diameters were similar on fluorescein angiography (238.20 μm) and OCT (242.72 μm).
- Intraretinal fluid was significantly more frequent than subretinal fluid (p=0.004).
Conclusions:
- Intraretinal macroaneurysms are increasingly diagnosed with multimodal imaging.
- A proposed classification simplifies IMs into primary or secondary types.
- This classification aids standardized terminology and consistent understanding of IMs.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
