Optical Coherence Tomography Features for Identifying Posttreatment Complete Polypoidal Regression in Polypoidal...

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Diseases

Background:

• Polypoidal choroidal vasculopathy (PCV) is a common subtype of age-related macular degeneration.
• Accurate assessment of treatment response is crucial for managing PCV.
• Optical coherence tomography (OCT) and indocyanine green angiography (ICGA) are key diagnostic tools.

Purpose of the Study:

• To evaluate the accuracy of posttreatment OCT features in determining complete or incomplete polypoidal regression in PCV.
• To assess the relative risk (RR) associated with specific OCT characteristics for regression outcomes.

Main Methods:

• A validity analysis was conducted on treatment-naive PCV eyes.
• OCT and ICGA were performed at baseline and posttreatment.
• Two graders identified regression on ICGA, while two others classified OCT features of pigment epithelial detachment (PED).

Main Results:

• Posttreatment OCT features showed high accuracy in predicting regression.
• Features A or B on OCT were highly accurate (86%) for complete regression (RR 5.0).
• Feature D on OCT was highly accurate (85%) for incomplete regression (RR 4.6).

Conclusions:

• OCT features alone can accurately identify posttreatment polypoidal regression in PCV.
• This finding may reduce the need for ICGA in posttreatment assessment.
• OCT provides a reliable method for monitoring treatment efficacy in PCV.
