Purpose: To investigate the clinical features of simple hemorrhage (SH) and myopic choroidal neovascularization (mCNV) lesions in pathologic myopia (PM) accompanied with lacquer cracks (LCs).
Methods: Altogether 105 PM subjects were recruited with fifty-eight eyes categorized as group LC + SH and sixty eyes as group LC + mCNV. LCs were categorized into stellate and linear subtypes. Eye fundus photography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography were performed. Clinical demographic data, PM maculopathy, peripapillary atrophy, and macular choroidal thickness (mCT) were documented.
Results: Significant differences in age, gender, BCVA, and PM atrophies were observed between LC + SH and LC + mCNV groups. The stellate LC was more common in elder subjects with more severe chorioretinal atrophy and thinner mCT compared with linear LCs (P < 0.05). The mCT in group LC + SH was significantly larger than group LC + CNV (P < 0.001), especially in temporal, inferior, and superior locations of macula. The mCT showed correlation with age (P < 0.001)with a decreasing rate of 0.696 μm/year.
Conclusions: SH tended to initially occur in younger subjects with linear LCs. mCNV was more common in elder subjects with severe chorioretinal atrophy. Stellate LCs were associated with the worse PM lesions.
