Diabetic retinopathy (DR) is a complication of diabetes that can lead to vision loss. Early detection and treatment of DR are essential to prevent vision loss. Traditional fundus photography (FP) is a common screening method for DR. Still, it has limitations in detecting diabetic macular edema (DME), a type of fluid buildup in the macula, the central part of the retina. The research explores the potential of self-imaging optical coherence tomography (SI-OCT) as a more effective and cost-effective screening tool for DR, particularly for DME detection. Self-Imaging OCT is a non-invasive imaging technique that provides high-resolution cross-sectional images of the retina.
The research discusses a study that compared the performance and cost-effectiveness of three DR screening strategies:
FP-based screening: This traditional method relies on fundus photographs to detect DR.
FP + SI-OCT screening combines FP with SI-OCT imaging for a more comprehensive assessment.
FP + manual SD-OCT screening: This approach uses FP combined with standard spectral-domain OCT (SD-OCT), which requires a more complex and expensive setup than SI-OCT.
The study results showed that the FP + SI-OCT strategy offered the following advantages:
Higher sensitivity and specificity for detecting DME: SI-OCT’s high-resolution imaging allowed for better detecting fluid buildup in the macula, a hallmark of DME.
Improved cost-effectiveness: Compared to FP + manual SD-OCT, the FP + SI-OCT strategy proved more cost-effective due to the simpler and less expensive SI-OCT technology.
In conclusion, this study suggests that Self-Imaging OCT holds promise as a valuable tool for DR screening, particularly for DME detection. Its effectiveness and cost-effectiveness make SI-OCT a promising candidate for wider adoption in DR screening programs.
