To investigate the risk factors for myopic choroidal neovascularization (mCNV) development in highly myopic patients with unilateral mCNV.
There were no significant differences in IOP, AL, RE, and chorioretinal degeneration. The affected eyes had significantly poorer BCVA (P<0.001) and a higher Lc grade (P<0.01). The differences in subfoveal and superior CTs did not reach significance; however, the inferior CT and the average of the three CT values were significantly less in affected eyes (P<0.05 for both comparisons). The height of the posterior staphyloma did not reach significance; however, the affected eyes had a significantly longer RPE curvature (P<0.05).
Stretching of the posterior pole based on the increasing RPE/choroid curvature rather than ocular expansion seems to be a greater risk factor for mCNV.
