Therefore, confocal scanning laser ophthalmoscopy may be particularly useful for early diagnosis of glaucoma. This article reviews the application of such instrument, the Heidelberg retina tomograph, Heidelberg retina angiorgraphy,Heidelberg retina flowmeter.展开更多
目的探讨正常人眼黄斑区视网膜阈值敏感度和黄斑注视情况。方法使用激光扫描检眼镜,对61人61只正常眼进行微视野检查,测量黄斑区10°范围内40个点的阈值敏感度以及黄斑注视情况。分析视网膜不同部位及年龄与视觉敏感度之间的相关性...目的探讨正常人眼黄斑区视网膜阈值敏感度和黄斑注视情况。方法使用激光扫描检眼镜,对61人61只正常眼进行微视野检查,测量黄斑区10°范围内40个点的阈值敏感度以及黄斑注视情况。分析视网膜不同部位及年龄与视觉敏感度之间的相关性。结果距中心凹相同距离、不同方位的视网膜阈值敏感度差异无统计学意义。距中心凹距离和年龄分别与局部视网膜阈值敏感度呈负相关。距中心凹距离每增加1°,视网膜阈值敏感度下降0.34 dB 年龄每增加10岁,阈值敏感度下降0.40 dB。正常人眼均为中心凹注视。注视点稳定性以协方差矩阵值（｜s｜）表示,95%正常值参考范围为0-0.12度4。结论在黄斑区10°范围内,距中心凹距离和年龄对视网膜阈值敏感度有显著影响。测量局部视网膜敏感度和黄斑注视情况,可作为视功能指标用于黄斑病变的随访和疗效判断,也有助于在黄斑疾病的手术治疗中保护注视点。展开更多
