A cross-sectional study. A total of 129 congenital cataract patients after congenital cataract extraction (40 in GFCS and 89 in NGFCS) were enrolled in this study from December 2020 to March 2021. All participants, age range from 4 to 18 years old, completed OCT examinations (including macular structure parameters, optic nerve fiber layer thickness periphery retinal nerve fiber layer [pRNFL], and sub foveal choroidal thickness [SFCT]). All the NGFCS participants underwent OCTA examinations (including vessel density (VD) and perfusion density (PD) of macular and peripapillary area.). Linear regression models were used to examine the effect of various factors on different ocular parameters. Vascular-structural associations were assessed with Spearman correlation. Diagnostic ability was evaluated with area under the receiver operating curve (AUC).
To quantitatively analyze the fundus structure and microvascular characteristics of GFCS and non-GFCS (NGFCS) using optical coherence tomography angiography (OCTA), to explore the vascular-structural association, and to assess the diagnostic abilities of structure parameters.
