Purpose To evaluate changes in macular morphology due to myopic choroidal neovascularization (CNV), using spectral-domain optical coherence tomography (SD-OCT). Methods In all, 22 eyes with recent-onset untreated CNV underwent 1 intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF), followed by a pro-re-nata regimen. SD-OCT was performed at baseline (before first administration of anti-VEGF treatment) and month 1, and 2; macular morphologic changes and outer retina characteristics (SD-OCT findings) associated with CNV activity were evaluated. Sensitivity and specificity were calculated for SD-OCT findings using fluorescein angiography (FA) as standard reference. Results Mean central retinal thickness (CRT) showed no significant reduction from baseline (284 +/- 98 mu m) to month 1 (257 +/- 74 mu m) and month 2 (263 +/- 72 mu m). A hyper-reflective lesion with fuzzy borders (fuzzy area), and 'absent or altered' IS/OS junction were the only SD-OCT findings associated with CNV activity (P<0.0001). Both these SD-OCT findings showed good sensitivity and specificity (95.1 and 96.0% (95% CI: 0.87-0.89), respectively, for the fuzzy area; 87.9 and 66.7% (95% CI: 0.65-0.87), respectively, for 'absent or altered' IS/OS junction) when compared with FA leakage (standard reference). Conclusions Outer retina characteristics (ie, hyper-reflective lesion with fuzzy borders, and 'absent or altered' IS/OS junction) appear more meaningful than CRT in the evaluation of myopic CNV activity. These SD-OCT findings show overall good sensitivity and specificity when compared with FA leakage (standard reference), and could be considered as an alternative diagnostic tool to FA for myopic CNV monitoring.
