WIDE-FIELD SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY.

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Imaging

Background:

• Spectral domain optical coherence tomography (SD-OCT) is crucial for visualizing retinal structures.
• Understanding the interrelationships between the vitreous, retina, and choroid is vital for diagnosing and managing ocular diseases.

Purpose of the Study:

• To describe the wide-field SD-OCT morphologic relationships of the vitreous, retina, and choroid in healthy and pathologic eyes.
• To establish a comprehensive imaging protocol for extramacular regions.

Main Methods:

• Standardized horizontal, vertical, and oblique SD-OCT sections were acquired.
• Images were captured from 8 extramacular locations, including peripheral and vascular arcade regions.
• Wide-angle, equator-to-equator montage images were created using specialized software.

Main Results:

• Wide-field SD-OCT scans were successfully obtained from healthy subjects and patients with various retinal pathologies.
• Included conditions were central serous chorioretinopathy, wet and dry age-related macular degeneration, retinitis pigmentosa, and acute exudative polymorphous vitelliform maculopathy.
• The study demonstrated the feasibility of imaging extensive retinal areas.

Conclusions:

• Montaging SD-OCT images provides a novel approach to examine choroid, retina, and associated structures.
• This technique offers valuable applications for studying the vitreoretinal interface and paramacular/macular pathologies.
• The method facilitates a deeper understanding of ocular anatomy and disease.
