Objective To explore the optimal method of qualitative and quantitative assessment of retinal neovascularization(RNV),choroidal neovascularization(CNV) and leakage from CNV. Methods Thirteen mice were randomly divided into RNV assessment group(n=7)and CNV assessment group(n=6).For RNV assessment, 3 mice were served as normal controls,and the other 4 were made into models of retinopathy of prematurity(ROP).At postnatal d16,mice in normal control group and 3 ROP model mice received intraocular injection with FITC labeled or unlabeled antibody and were sacrificed 12 h later.The retinas were flat mounted(FITC labeled antibody) or incubated with secondary antibody(unlabeled antibody) and then flat mounted.The other ROP model mouse was served as blank control.For assessment of CNV and leakage from CNV,6 mice(12 eyes) were induced into models of CNV,and were randomly divided into two groups.Seven and 14d after model establishment,mice were intraocularly injected with unlabeled antibody,and fluorescein sodium were intraperitoneally injected 12 h later.The area of CNV and that of CNV leakage were calculated. ResultsRetinas from eyes injected with FITC labeled antibody exhibited good resolution of ultrastructure of RNV,while retinas from eyes injected with unlabeled antibody showed selective staining of RNV with no background,greatly facilitating identification and quantification of RNV.Merging images of stained CNV with images of fluorescein sodium leakage from CNV revealed double labeled CNV surrounded by fluorescein that had leaked into surrounding tissues.The mean area of CNV and its leakage of d14 were significantly different from those of d 7(P
