目的 :通过光学相干断层扫描(optical coherence tomography,OCT)观察妊娠高血压疾病患者眼底病变情况。方法:对98例妊娠高血压疾病患者进行矫正视力检查、眼底检查、OCT检查。观察患者OCT表现,分析OCT异常表现与矫正视力之间的相关性。结果:OCT检查有异常148眼(75.51%),其中视网膜神经上皮层浆液性脱离84眼(56.76%),色素上皮层及椭圆体层改变38眼(25.68%)。其他改变如视盘水肿,视网膜有出血、棉绒斑等改变26眼(17.56%)。患者OCT异常表现与矫正视力之间存在相关性(P<0.01),其中视网膜神经上皮层脱离对视力的影响最大。结论:75.51%的妊娠高血压疾病患者通过OCT检查出异常,其异常表现主要有3种,显示出OCT在该病眼底检查中的优势。
Objective: To observe the ocular fundus lesions in patients with pregnancy-induced hypertension by optical coherence tomography (OCT). Methods: 98 cases of pregnancy-induced hypertension patients were corrected visual acuity, fundus examination, OCT examination. OCT was observed in patients with OCT abnormalities and corrected visual acuity was analyzed. Results: There were 148 eyes (75.51%) with abnormal OCT examination. There were 84 eyes (56.76%) with serous detachment in retina and 38 eyes (25.68%) with changes in pigment epithelium and ellipsoid. Other changes such as optic disc edema, retinal hemorrhage, cotton linter and other changes in 26 eyes (17.56%). There was a correlation between OCT abnormalities and corrected visual acuity (P <0.01), and retinal neuroepithelial detachment had the most significant effect on visual acuity. Conclusion: 75.51% of patients with pregnancy-induced hypertension have abnormalities detected by OCT. There are mainly 3 abnormalities in OCT, which shows the advantages of OCT in the fundus examination.
