Background:

Vascular information in fundus images is crucial for diagnosing retinal diseases.
Pathological lesions, like Choroidal Neovascularization, interfere with accurate vascular analysis in OCT images.

Purpose of the Study:

To develop a novel method for detecting blood vessels in pathological OCT fundus images.
To overcome the interference caused by lesions in retinal vascular analysis.

Main Methods:

Preprocessing involves automatic localization and filling to reduce pathological interference.
Vessel extraction utilizes a pore ablation method based on a capillary bundle model after matched filter feature extraction.
Morphological operations are employed for final vascular feature extraction.

Main Results:

The proposed method demonstrates effective extraction of vascular information from pathological OCT images.
Achieved DICE, PRECISION, and TPR scores of 0.88 ± 0.03, 0.79 ± 0.05, and 0.66 ± 0.04, respectively.
Significantly reduced interference from diseased blood vessels.

Conclusions:

The developed method is effective for extracting vascular information from challenging OCT fundus images.
Accurate vascular extraction is vital for the diagnosis and treatment of retinal diseases.
The approach shows promise for improving clinical diagnostic capabilities.
