Abstract:
Objective To assess changes of blood flow density of idiopathic choroidal neovascularization (ICNV) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF).Methods Retrospective case analysis.Sixteen eyes of 16 patients with ICNV diagnosed with FFA and OCT were included in this study.Among them,12 were female and 4 were male.The mean age was 33.94±9.83 years.The mean course of diseases was 5.13 ±4.44 weeks.The BCVA,indirect ophthalmoscope,OCT and OCT angiography (OCTA) were performed at the first diagnosis in all patients.The BCVA was converted to logMAR.The macular fovea retinal thickness (CMT) was measured by OCT,and the selected area of CNV (CSA) and flow area of CNV (CFA) were measured by OCTA.The mean logMAR BCVA,CMT,CSA and CFA were 0.336±0.163,268.500±57.927 μm,0.651 ±0.521 mm2,0.327±0.278 mm2,respectively.All patients were treated with intravitreal ranibizumab (IVR,10 mg/ml,0.05 ml).Follow-up results including the BCVA,fundus color photography,OCT and OCTA were obtained 1 month after treatment.To compare the changes ofBCVA,CMT,CSA,CFA of ICNV treated with anti-VEGF.Pearson method was used to analyze the correlation between logMAR BCVA and CMT,CSA and CFA before and after the treatment.Results One month after treatment,the average logMAR BCVA,CMT,CSA and CFA were 0.176±0.111,232.500± 18.910 μm,0.420±0.439 mm2,0.215 ± 0.274 mm2.The mean logMAR BCVA (t=5.471,P＜ 0.001),CMT (t=2.527,P=0.023),CSA (t=4.039,P=0.001),CFA (t=4.214,P=0.001) significantly decreased at 1 month after injection compared to baseline,and the difference had statistical significance.The results of correlation analysis showed that the post-logMAR BCVA was moderately positively correlated with pre-CSA and post-CSA (r=0.553,0.560;P=0.026,0.024),and strongly correlated with pre-CFA and post-CFA (r=0.669,0.606;P=0.005,0.013),but not correlated with preCMT and post-CMT (r=0.553,0.560;P=0.026,0.024).Conclusion The blood flow density of ICNV measured by OCTA were significantly decreased in the treatment of anti-VEGF drugs.
