AB  - PURPOSE: To investigate the dilated choroidal veins (DCVs) at or around myopic 
      macular neovascularizations (MNVs) and to determine whether there is a 
      hemodynamic relationship between them. METHODS: Fifty-eight eyes of 57 patients 
      with myopic MNVs were examined. Dilated choroidal veins were defined as choroidal 
      veins whose diameter was 2X larger than adjacent veins. Indocyanine green 
      angiography and swept-source optical coherence tomography images were reviewed to 
      detect DCVs that crossed the subfoveal area. The filling sequence of the DCVs and 
      MNVs was determined. RESULTS: Patients' mean age was 71.4 +/- 10.6 years. The mean 
      axial length was 29.3 +/- 1.8 mm. Dilated choroidal veins below or around the MNV 
      were found in 17 eyes (29.3%). Emissaries of the short posterior ciliary arteries 
      were seen at or around MNVs in 8 of the 17 eyes. In these eyes, the short 
      posterior ciliary artery was filled first or almost simultaneously with the 
      filling of the MNV, followed by a laminar filling of the DCVs. In one eye, 
      afferent arterioles from the short posterior ciliary arteries and efferent 
      venules connected to DCVs were seen. CONCLUSION: Dilated choroidal veins are 
      present below or around MNVs in about 30% of eyes with myopic MNVs. Our findings 
      suggest that an MNV might be a vascular unit consisting of short posterior 
      ciliary arteries, afferent arterioles, efferent venules, and DCVs.
