Abstract
Purpose: :
To investigate the risk factors for myopic choroidal neovascularization (mCNV) development in highly myopic patients with unilateral mCNV.
Results: :
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).
Conclusions: :
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.
