Traction-Induced Structural Failure States in Macular Hole Formation Revealed by Volume-Rendered Swept-Source OCT.

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomechanical Engineering

Background:

• Macular holes are a significant cause of vision loss.
• Understanding the development of macular holes is crucial for effective treatment.
• Current imaging techniques may not fully capture the dynamic vitreomacular interface.

Purpose of the Study:

• To analyze macular hole development using 3D visualization of vitreomacular architecture via volume-rendered optical coherence tomography (OCT).
• To interpret observed anatomic configurations using structural and mechanical principles.

Main Methods:

• Retrospective observational study of eyes with developing macular holes imaged with swept-source OCT.
• Volumetric datasets processed for 3D visualization of vitreous attachment, deformation, and retinal changes.
• Anatomic configurations evaluated descriptively, with terminology for OCT-based structural failure states.

Main Results:

• Seventeen eyes analyzed, showing diverse configurations linked to persistent vitreous attachment.
• 3D visualization revealed asymmetric vitreous attachment, vitreous tears, and retinal flaps not seen in planar imaging.
• Longitudinal imaging demonstrated variable transitions between configurations, driven by vitreous attachment changes.

Conclusions:

• Volume-rendered swept-source OCT provides direct visualization of vitreomacular architecture during macular hole development.
• Observed configurations represent traction-induced structural failure states, not a linear temporal sequence.
• This framework explains the diversity, asymmetry, and nonuniform evolution of macular hole morphology.
