Clinical anatomy of the macula

Area of Science:

• Ophthalmology
• Retinal Imaging
• Neuroscience

Background:

• The macula, central to high-resolution color vision, possesses a complex structure vital for central vision.
• Understanding its microanatomy is crucial for interpreting retinal images and managing macular diseases.

Purpose of the Study:

• To provide an integrative overview of macular anatomy, emphasizing microanatomical features relevant to retinal imaging and disease management.
• To bridge classic histological findings with modern imaging for enhanced comprehension of macular health and pathology.

Main Methods:

• A comprehensive PubMed/MEDLINE search was conducted for English-language articles up to February 28, 2025.
• Relevant keywords included "macula," "fovea," "optical coherence tomography," and "retinal anatomy."
• Reference lists of identified papers were reviewed for additional sources, considering diverse study types.

Main Results:

• The fovea and foveola, rich in cone photoreceptors, are central to sharp vision.
• The Henle fiber layer and surrounding regions support central vision, with OCT revolutionizing visualization of macular architecture.
• Key features like the foveal avascular zone and Muller glial cells are explored in relation to high-resolution imaging, enhancing diagnostic precision.

Conclusions:

• Comprehensive knowledge of macular anatomy is essential for accurate retinal imaging interpretation and managing central retinal disorders.
• Integrating histological and modern imaging data improves understanding and management of macular diseases.
• This review serves as a reference for clinicians and researchers, highlighting the need for further studies on emerging imaging technologies for early detection and treatment.
