    Abstract:
    PURPOSE: To detect, using multimodal imaging, lacquer cracks (LCs) and myopic stretch lines (MSLs) in pathologic myopic eyes with macular hemorrhage (MHE) and those without. METHODS: We collected 18 consecutive pathologic myopic eyes (spherical equivalent ≤ -8.0 diopters) that had presented with linear, yellowish-white lesions in the macula. We categorized the eyes into either the MHE group or the non-MHE group. All underwent fluorescein angiography (FA), near infrared autofluorescence (NIA), indocyanine green angiography (ICGA), and spectral-domain optical coherence tomography (SD-OCT). RESULTS: In all 18 eyes, the linear lesions were hyperfluorescent under NIA imaging, but hypofluorescent under ICGA. All ten eyes in the MHE group had LCs, and two had both LCs and MSLs. None of the eight eyes in the non-MHE group had LCs. Regarding proximity to the MHE, LCs tended to locate closer than MSLs. Incidental perforating scleral vessels were clearly visible on the tracked SD-OCT scanning line, joining the choroid beneath the border of MHE. Sample cases are illustrated using delicate photographs and explanations. CONCLUSION: NIA imaging combined with SD-OCT and ICGA can detect and differentiate early the subtle difference between the two types of linear lesions in pathological myopic eyes. Notably, MSLs were not associated with MHEs or LCs in our consecutive series.
