OBJECTIVES: To investigate the correlation between the AI-measured area of the lacquer cracks (LC) at their first detection and the occurrence of a choroidal neovascularization (CNV) during the follow-up in patients affected by pathologic myopia. Secondary outcome was the detection of a correlation between the time to onset of CNV with both baseline LC area and LC area increase during follow-up.
METHODS: Optical coherence tomography (OCT) acquisitions of patients diagnosed with LC were retrospectively analysed. The study population was divided in a CNV group (showing the documented onset of a CNV) and a n-CNV group (no CNV development during follow-up). LC area was measured using MatLab software after the application of a customized method for LC segmentation on infrared (IR) enface images.
RESULTS: Forty-five (45) patients with a mean follow-up of 4.9 ± 1.5 years were included. LC area at baseline was 2.82 ± 0.54 mm2 and 1.70 ± 0.49 mm2 in CNV (20 patients) and n-CNV group (25 patients) group respectively (p < 0.001). LC area increase was significantly higher in CNV group (p < 0.001). Time to onset of CNV was linearly correlated with both LC area at baseline (p = 0.006) and LC area increase (p < 0.001).
CONCLUSIONS: Myopic CNV development is associated with lager LC areas and higher LC area increase during time. Earlier CNV onset is inversely correlated with LC area and LC area increase.
