Abstract:
Objective To observe and classify the characteristics of optical coherence tomography (OCT) for several common diseases which could lead to submacular choroidal neovascularization (CNV), and to provide the warrant to make the differential diagnosis and treatment of CNV. Methods The data of OCT of 165 patients (187 eyes) with CNV due to AMD, CEC, high myopia and ICNV diagnosed by fundus photography and fundus fluorescein angiography (FFA) were retrospectively analyzed, and the images of OCT were classified considering the results of FFA, and the characteristics of different types of the images were sumerized. Results Well-defined fusiform thickening of retinal pigment epithelial (RPE) and choriocapillary layer in CNV with well-defined border (60 eyes), dispersed backscattering increase in poorly-defined CNV (101 eyes), optic darkspace beneath RPE layer in serous detachment of RPE layer (19 eyes), quickly decreased high backscattering region under RPE layer in hemorrhagic detachment of RPE layer (11 eyes), slight to moderate backscattering region between RPE layer in fibrovascular detachment of RPE layer (10 eyes), and detachment of neurepithelial layer from RPE layer with the optic darkspace between the layers in detachment of neurepithelial layer (45 eyes) were observed. Conclusions The images of OCT for the common diseases which could lead to submacular choroidal neovascularization may be divided into 6 types. Analyzing the characteristics of images of OCT is helpful in differential diagnosis and treatment of CNV.
