The invention discloses a premature infant
retina plus
lesion detection method and
system, and the method comprises the steps: firstly inputting a to-be-detected
retina posterior pole image into an
image quality detection model for quality evaluation, and inputting a qualified image into a
blood vessel recognition model to obtain a
blood vessel graph; inputting the
blood vessel graph into a lesiondetection model, and outputting the probability of the corresponding
lesion types of plus, pre-plus and no-plus; and converting the probability of the
lesion type of the lesion examination into a corresponding i-ROP lesion
score according to a preset
score conversion equation to reflect the continuity of the
retinopathy degree. According to the invention, the severity of plus lesion is objectively measured, and the severity is tracked over time to provide
objective assessment of
disease progression or regression; by analyzing the change of the
score along with the time, the eyes which progress into plus lesion ROP can be recognized in advance under most conditions for early intervention,
disease delay caused by insufficient diagnosis is prevented, the accuracy of lesion degree detection is high, and the ophthalmoscope examination frequency of doctors can be greatly reduced.
