N2 - Purpose To describe fundus autofluorescence (FAF) patterns of myopic choroidal neovascularization (CNV) treated with intravitreal ranibizumab and their correlation with visual acuity. Design Prospective interventional case series. Methods Twenty-seven eyes (27 patients) affected by myopic CNV were enrolled from January 2011 to January 2013. All patients underwent a complete ophthalmologic examination, including best-corrected visual acuity (BCVA) determination and fundus autofluorescence (FAF). The patients underwent ranibizumab injections following a pro re nata treatment regimen. The main outcome measure was the identification of the FAF patterns of myopic CNV over a 12-month follow-up. The secondary outcome was the correlation of the FAF patterns with the BCVA. Results At baseline 17 eyes (63%) showed a hyperautofluorescent pattern and 10 eyes (37%) a patchy pattern. BCVA changed from 0.48 ± 0.23 (logMAR) to 0.30 ± 0.32 at the 12-month examination (P =.027) in the hyper-FAF subgroup. In the subgroup showing the patchy pattern, the BCVA declined slightly from 0.51 ± 0.27 to 0.56 ± 0.37 (P =.53). The 14 eyes preserving the hyper-FAF pattern during the follow-up had a final BCVA of 0.20 ± 0.17, whereas the 9 eyes maintaining the patchy pattern showed a final BCVA of 0.60 ± 0.37 (P =.002). The atrophic area of the retinal pigment epithelium assessed on the basis of FAF increased from 1.27 ± 2.80 mm2 to 1.83 ± 3.74 mm2 at the 12-month examination (P =.016). The mean atrophic area increased by 0.37 mm2 in the hyper-FAF subgroup and by 0.90 mm2 in the patchy FAF subgroup. Conclusions Two main patterns were identified on FAF in myopic CNV and were related to the prognostic evolution, the hyperautofluorescent CNV being associated with a greater visual gain and fewer atrophic changes over a 12-month follow-up.
