This study quantifies peripheral distortion in ultra-widefield fundus imaging, developing correction models for accurate retinal structure analysis across various eye conditions and devices.

Area of Science:

Ophthalmology
Medical Imaging
Optical Engineering

Background:

Ultra-widefield (UWF) fundus imaging offers extensive retinal visualization.
Peripheral distortion can affect quantitative analysis in UWF images.
Standardized correction methods are needed for diverse ocular parameters.

Purpose of the Study:

To create a quantitative database for correcting peripheral distortion in UWF fundus imaging.
To account for variations in axial length (AXL), optical media, and posterior staphyloma.
To develop analytical models for distortion correction.

Main Methods:

Utilized 3D printed model eyes imaged with two UWF systems (Optos 200Tx, Clarus 700).
Quantified peripheral distortion index (PDI) at various angles under air and balanced salt solution (BSS).

Developed continuous correction models and calculated staphyloma-specific correction factors.

Main Results:

PDI increased nonlinearly with peripheral angle, significantly higher in Optos 200Tx than Clarus 700.
Distortion was slightly greater under air than BSS for both systems.
Analytical models accurately reproduced measured distortion (R² = 0.976-0.993).
Posterior staphyloma models showed reduced distortion with correction factors ranging from 0.904 to 0.984.

Conclusions:

A comprehensive quantitative correction database and analytical models for UWF imaging distortion were established.
These tools enable accurate distortion correction across varying AXL, media, and ocular pathologies.
Validated correction database ensures reproducible quantification of retinal structures.
