Objective To observe the image characteristics ofmultispectral scanning laser imaging (MSLI) and OCT in patients with pregnancy induced hypertension syndrome (PIHS).Methods A total of 112 patients (224 eyes) of PIHS patients diagnosed in Obstetrics Department of Tianjin First Central Hospital from May 2016 to May 2017 were included in this study.The average age of the patients was 27.00±2.14 years.The average course of the disease was 15.00 ±8.27 days.There were 174 eyes in 87 patients of blurred vision,dazzling and visual fatigue consciously.All patients performed BCVA,direct ophthalmoscope,B ultrasound,confocal scanning laser Ophthalmoscope (cSLO) and spectral-domain OCT (SD-OCT).SD-OCT was performed with Spectralis HRA+OCT from Heidelberg Company in Germany to acquire tomographic images.Using Herdelberg's colorful program (MultiColor) based on cSLO and operating in accordance with standard methods,one scan simultaneously obtained blue light reflection based on 488 nm,green light reflection based on 515 nm,and infrared reflection based on 820 nm,synthesis to MSLI.Fundus abnormalities were classified into arterial spasm (stage Ⅰ),arteriosclerosis (stage Ⅱ),and retinopathy (stage Ⅲ).OCT examination was divided into normal and abnormal cases according to the abnormality of retinal morphology and thickness.Results Of the 224 eyes,68 eyes (30.36％) showed normal fundus examination and 156 eyes (69.64％) showed abnormal fundus performance.Among them,28 eyes were stage Ⅰ (17.95％);40 eyes were stage Ⅱ (25.64％);88 eyes were stage Ⅲ (56.41％).Thirty-six eyes (16.07％) showed normal fundus and 188 eyes (83.93％) showed abnormal performance with OCT.Of the 188 eyes with abnormal fundus performance,86 eyes (45.74％) had retinal neuroepithelial serous detachment;56 eyes (29.79％) had RPE detachment;optic disc edema,bulge,and local reflexes in the retinal nerve fiber layer were enhanced and/or the thickness increased in 46 eyes (24.47％).In MSLI,48 eyes (21.43％) showed normal fundus;176 eyes (78.57％) showed abnormal performance.Retinal edema was showed in green on MSLI,serous retinal neuroepithelial layer detachment,RPE layer detachment,retinal nerve fiber layer thickening,accompanied by changes in local retinal structure.The higher the degree of bulge,the darker the color.Consistent with the range of retinal edema revealed by SD-OCT.Conclusions MSLI and SD-OCT images show highly consistent lesions in PIHS patients.MSLI can more clearly show superficial and deep retinal lesions.
