Using optical coherence tomography angiography to guide the treatment of pathological myopic patients with submacular hemorrhage.

The present study aimed to investigate whether optical coherence tomography angiography (OCTA) could be used to guide the treatment of pathological myopic patients with submacular hemorrhage. Two pathological myopia patients with submacular hemorrhage were examined. Initially, choroidal neovascularization (CNV) was not observed during fundus angiography in both patients. However, based on OCTA, the first patient was diagnosed with myopic lacquer crack-related macular hemorrhage, and the second with CNV secondary to punctate inner choroidopathy. The first patient was treated with traditional Chinese medicine administered orally, and the second with intravitreal injections of anti-vascular endothelial growth factor (VEGF). Lesions in both patients were resolved. Submacular hemorrhage in pathological myopia patients could be caused by numerous mechanisms. OCTA is useful in differentiating inflammatory CNV from inflammatory lesions, particularly if CNV is not detected using other multimodal imaging techniques.
