目的探讨白内障术中用眼科广域数字化视网膜成像系统(WFIS SW-8000)对术前高度怀疑有眼底病变的白内障患者行实时检查和治疗的可行性及其临床意义。
方法采用系列病例观察法，于2019年4月至2019年7月纳入在南通大学附属医院因严重白内障接受白内障超声乳化摘出联合人工晶状体(IOL)植入术的白内障患者90例96眼。所有患者根据术前相关病史疑有术眼眼底病变但术前眼底无法窥入。术中摘出患眼白内障后即刻用WFIS SW-8000行眼底照相，实时进行眼底检查并及时治疗。术后采用前置镜辅助的裂隙灯显微镜进行眼底检查，同时行光相干断层扫描(OCT)及荧光素眼底血管造影(FFA)检查，将术后各项检查结果与术中检查结果进行对照，以验证术中诊断的准确性。
结果白内障术中发现患眼存在眼底病变者40眼，检出率为41.67%，其中干性年龄相关性黄斑变性(AMD)者2眼、湿性AMD者3眼、息肉状脉络膜血管病变(PCV)者1眼、高度近视性视网膜病变(HMR)者7眼、视网膜中央静脉阻塞(CRVO)伴黄斑水肿者1眼、轻度非增生性糖尿病视网膜病变(NPDR)者12眼、中度NPDR者7眼、重度NPDR者4眼、增生性糖尿病视网膜病变(PDR)者3眼；术后检查发现眼底病变者45眼，检出率为46.88%，与术中检出率比较差异无统计学意义( χ 2＝0.528， P＝0.468)。白内障术中诊断为眼底新生血管性疾病或黄斑水肿者共22眼，经患者知情同意对其中11眼行玻璃体腔抗炎和/或抗血管内皮生长因子(VEGF)注射。
结论白内障术中用WFIS SW-8000进行实时眼底病诊断是可行的，有助于对白内障合并严重眼底病患者的眼底疾病进行及时干预。
ObjectiveTo investigate the feasibility of real-time screening and diagnosing fundus diseases with Wild Field Imaging System (WFIS SW-8000) in the eyes with dense cataract patients.
MethodsA series of case-observational study was carried out.Ninety-six dense cataractous eyes of 90 patients with suspected fundus diseases were included in Affiliated Hospital of Nantong University from April to July 2019.Lens phacoemulsification combined with intraocular lens implantation was performed after the opacity lens was removed, and fundus examination was performed with WFIS SW-8000.Super field lens, optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) was used to verify the fundus findings after surgery, which were compared with WFIS SW-8000.This study protocol was approved by Ethics Committee of Affiliated Hospital of Nantong University and followed the Declaration of Helsinki.Written informed consent was obtained from each patient prior to any medical examination.
ResultsAmong 96 eyes, fundus diseases were detected in 40 eyes with the detection rate of 41.67% by WFIS SW-8000 examination, including dry age-related macular degeneration (AMD) in 2 eyes, wet AMD in 3 eyes, polypoidal choroidal vasculopathy (PCV) in 1 eye, high myopia retinopathy (HMR) in 7 eyes, central retinal vein occlusion (CRVO) with macular edema (ME) in 1 eye, mild non-proliferative diabetic retinopathy (NPDR) in 12 eyes, moderate NPDR in 7 eyes, severe NPDR in 4 eyes and proliferative diabetic retinopathy (PDR) in 3 eyes.Fundus diseases were detected in 45 eyes with detection rate of 46.88% after surgery by a super field lens, OCT and FFA.The detectable rate of digital retinal camera examination and super field lens, OCT and FFA showed no significant difference between intraoperation and postoperation (χ 2=0.528, P=0.468). Twenty-two eyes with fundus neovascular disease or macular edema requiring drug intervention were identified intraoperatively, and intravitreal anti-inflammatory and/or anti-vascular endothelial growth factor (VEGF) drugs were injected in 11 eyes during the operation.
ConclusionsWFIS SW-8000 is a useful tool for the accurate and convenient method in real-time fundus examination during phacoemulsification, which is feasible and helpful for timely intervention in and treatment of fundus diseases.
