Fundus autofluorescence in central serous chorioretinopathy: association with spectral-domain optical coherence tomography and fluorescein angiography

and FA for identifying pathological abnormalities in CSC. The characteristics of IA AF in CSC were attributable to the modification of melanin in the RPE. IR- AIM: To evaluate the correlation among changes in fundus autofluorescence (AF) measured using infrared fundus AF (IR -AF) and short-wave length fundus AF (SW -AF) with changes in spectral -domain optical coherence tomography (SD -OCT) and fluorescein angiography (FA) in central serous chorioretinopathy (CSC). METHODS: Two hundred and twenty consecutive patients with CSC were included. In addition to AF, patients were assessed by means of SD -OCT and FA. Abnormalities in images of IA -AF, SW -AF, FA were analyzed and correlated with the corresponding outer retinal alterations in SD-OCT findings. RESULTS: Eyes with abnormalities on either IR-AF or SW-AF were found in 256 eyes (58.18%), among them 256 eyes (100%) showed abnormal IR -AF, but SW-AF abnormalities were present only in 213 eyes (83.20%). The hypo-IR-AF corresponded to accumulation of subretinal liquid, collapse of retinal pigment epithelium (APE) or detachment of APE with or without RPE leakage point in the corresponding area. The hyper -IR -AF corresponded to the area with loss of the ellipsoid portion of the inner segments and sub -sensory retinal deposits or focal melanogenesis under sensory retina. The hypo-SW-AF corresponded to accumulation of subretinal liquid or atrophy of RPE. The hyper -SW -AF associated with sub -sensory retinal deposits, detachment of RPE and focal melanogenesis. CONCLUSION: IR-AF was more sensitive than SW-AF AF should be used as a common diagnostic tool for identifying pathological lesion in CSC.

基于GMPE模块OCT与眼底彩色照相法测量客观眼球旋转度的比较

目的:比较基于GMPE模块光学相干断层扫描(OCT)与传统眼底彩色照相法(FCP)测量客观眼球旋转度的一致性和可行性。方法:纳入2020-12/2021-03我院斜弱视门诊受检者,同一天用基于GMPE模块OCT与FCP两种方法测量客观眼球旋转度。FCP使用Adobe Photoshop软件手动定位测量黄斑中心凹-视盘中心夹角度数(FDA),基于GMPE模块OCT软件自动定位黄斑和视盘中心测量FDA。结果:纳入55例受检者,OCT测量FDA分别为右-6.6°±4.5°和左-8.8°±4.7°,FCP测量FDA分别为右-6.6°±4.7°和左-8.4°±4.1°,两种方法测量结果无差异(P_(右眼)=0.90,P_(左眼)=0.08)。外斜视患者OCT测量FDA分别为右-5.8°±4.9°和左-9.1°±4.5°,FCP测量FDA分别为右-5.7°±5.0°和左-8.6°±4.3°(P_(右眼)=0.75,P_(左眼)=0.15)。类似地,内斜视患者OCT测量FDA分别为右-9.0°±7.3°和左-11.3°±3.5°,而FCP测量FDA分别为右-10.0°±7.0°和左-10.1°±2.8°(P_(右眼)=0.21,P_(左眼)=0.10),两种测量方法在内外斜视患者中均无差异(P>0.05)。Pearson检验及Bland-Altman分析两种方法的结果高度相关一致(r_(右眼)=0.93,r_(左眼)=0.94,均P<0.01)。结论:基于GMPE模块OCT可用于客观眼球旋转度的测量,且可信度及重复度高,临床有望替代眼底彩色照相法。
