广角激光扫描检眼镜用于眼全科门诊近视患者周边视网膜病变筛查的研究

  目的  应用超广角激光扫描检眼镜检测“健康”近视人群中周边视网膜病变的发生情况，探讨其在眼科全科门诊进行近视患者周边视网膜病变筛查的可行性和意义。  方法  本研究采用回顾性分析，收集2021年10月—2022年3月于宁波大学附属人民医院眼科中心眼全科门诊就诊进行眼科体检的近视患者210例共210只右眼，根据等效球镜绝对值分为3组，低度近视组(≤3.00 D，43例)、中度近视组(3.00~6.00 D，98例)、高度近视组(≥6.00 D，69例)。IOL-Master测量眼轴和角膜曲率，应用Optomap Daytona 200T超广角激光扫描检眼镜拍摄视网膜，记录周边视网膜病变发生情况。  结果  患者年龄为(24.97±7.39)岁，等效球镜为(-5.02±2.11)D。周边视网膜病变检出率为30.95%(65例)，视网膜非压迫白(WWOP)检出率为26.19%(55例), 格子样变性(LD)检出率为6.67%(14例)。其中高度近视组周边视网膜病变46.38%(32例)]、WWOP39.13%(27例)]检出率最高，低度近视组周边视网膜病变11.63%(5例)]和WWOP9.30%(4例)]检出率最低。高度近视组LD检出率14.49%(10例)]高于中度近视组3.06%(3例)]与低度近视组2.32%(1例)]。近视眼周边视网膜病变检出率、WWOP检出率和LD检出率分别与近视等效球镜绝对值、眼轴呈正相关关系(均P < 0.05)。  结论  超广角激光扫描检眼镜是检查近视性周边视网膜病变的有用筛查工具。无论近视程度如何，都需要仔细进行周边眼底检查，以便更好地进行早期诊断和管理。 

Screening to detect peripheral retinal lesions in myopic eyes using ultrawide field scanning laser ophthalmoscopes in the outpatient general ophthalmology clinics

  Objective  To detect the incidence of peripheral retinal lesions in healthy myopic eyes using ultrawide field scanning laser ophthalmoscopes, and further explore the feasibility and significance of screening to detect peripheral retinal lesions in myopic eyes using ultrawide field scanning laser ophthalmoscopes in the outpatient general ophthalmology.  Methods  This retrospective study included a total of 210 healthy myopic patients (210 eyes), who had visited the outpatient general ophthalmology clinics of the Affiliated People ' s Hospital of Ningbo University. The eyes were divided into three groups based on the spherical equivalent refraction (SER): low myopia (≤ 3.00 D, 43 cases), moderate myopia (3.00-6.00 D, 98 cases) and high myopia (≥ 6.00 D, 69 cases). An IOL-Master was used to measure the axial length and corneal curvature. The retina was photographed with Optomap Daytona 200T ultrawide field scanning laser ophthalmoscopes and the peripheral retinal lesions was recorded.  Results  The mean age of the patients was (24.97±7.39) years, and the mean SER was (-5.02±2.11) D. The detection rate was 30.95% (65 cases) in peripheral retinal lesions, 26.19% (55 cases) in white without pressure (WWOP), and 6.67% (14 cases) in the lattice degeneration (LD), respectively. The high myopia group showed the highest detection rate of peripheral retinal lesions (46.38%, 32 cases) and WWOP (39.13%, 27 cases). Meanwhile, low myopia group showed the lowest detection rate of peripheral retinal lesions (11.63%, 5 cases) and WWOP (9.30%, 4 cases). The detection rate of LD in high myopia group 14.49% (10 cases)] were higher than that in moderate myopia group 3.06% (3 cases)] and low myopia group 2.32% (1 cases)]. The detection rate of peripheral retinal lesions, WWOP and LD in myopic eyes were positively correlated with the axial length and absolute values of SER, respectively (all P < 0.05).  Conclusion  Ultrawide field scanning laser ophthalmoscope is a potentially useful screening tool for the detection of peripheral retinal lesions in myopic eyes. Careful peripheral fundus examinations are needed for better early diagnosis and management regardless of myopia severity.
