Factors Affecting Cirrus-HD OCT Optic Disc Scan Quality: A Review with Case Examples

Area of Science:

• Ophthalmology
• Medical Imaging
• Glaucoma Research

Background:

• Spectral-domain optical coherence tomography (SD-OCT) is vital for glaucoma detection and progression monitoring.
• Advancements in OCT hardware and software have increased its clinical adoption.
• However, imaging artifacts in OCT scans are common and can impede accurate interpretation.

Purpose of the Study:

• To identify factors influencing the quality of optic disc scans obtained with Cirrus High Definition OCT (HD-OCT).
• To analyze the impact of these factors on measurement variability in glaucoma assessment.

Main Methods:

• Review of clinical practice data involving Cirrus HD-OCT optic disc scans.
• Analysis of image quality metrics and associated measurement variability.
• Identification of common artifact types and their origins.

Main Results:

• Several factors were identified that significantly affect Cirrus HD-OCT optic disc scan quality.
• These factors contribute to variability in key glaucoma measurement parameters.
• Understanding these factors is essential for reliable clinical interpretation.

Conclusions:

• Knowledge of imaging artifacts in OCT is necessary for accurate glaucoma diagnosis and management.
• Addressing scan quality issues in Cirrus HD-OCT can improve the reliability of glaucoma monitoring.
• Further research into artifact reduction techniques is warranted.
