摘要
目的比较单视野、双视野45度和60度眼底摄影检测视网膜新生血管(NVEs)的有效性;比较以中央窝为中心的45度视场、中央窝与椎间盘之间以及沿鼻盘边缘的鼻缘与标准60度一视场和二视场的NVEs检测。方法两名眼科医生评估了1997- 1999年3年间72例NVEs患者中58例的无红、黑、白筛查和随访照片。评估包括分析在两个标准60度视场上放置的透明网格界定的不同摄影视场中确定的NVEs的数量、大小和位置。结果在45度黄斑视野检测中,60度中央凹中心照片检测到的NVEs分别为59/81(73%)、50/81(62%)和64/81(79%)。检测至少一种NVE的Kappa值为0.62 (95% CI 0.40-0.83)、0.38 (95% CI 0.19-0.57)和0.83 (95% CI 0.62-0.99)。与双视场60度摄影相比,相应的数据分别为59/111(53%)、50/111(45%)和64/111(58%)。一个以黄斑为中心的60度视场显示了81/111(73%)的nve,这些nve是通过60度双视场摄影和附加的视盘为中心的视场检测到的。双视野45度摄影揭示了86/111(77%)双视野60度摄影检测到的NVEs。仅在视盘中心的60度视场中检测到的nve,在相应的45度视场中也检测到90%。结论单视场45度摄影不能作为糖尿病视网膜病变的筛查方法。双视野45度摄影(以黄斑为中心和盘状为中心的视野)显示了77%的nve被相应的双视野60度摄影检测到。
Detection of retinal neovascularizations using 45 ° and 60 ° photographic fields with varying 45 ° fields simulated on a 60 ° photograph
PURPOSE To compare the effectiveness of one- and two-field 45 degrees and 60 degrees fundus photography for detection of retinal neovascularizations (NVEs); to compare the detection of NVEs in macular 45 degrees fields centred on the fovea, between the fovea and the disc and with the nasal border along the nasal disc margin with that in standard 60 degrees one- and two-fields. METHODS Two ophthalmologists assessed red-free, black and white screening and follow-up photographs of 58 out of a total 72 patients referred for treatment for NVEs over the 3 year period 1997-99. The assessment included analysis of the numbers, sizes and locations of NVEs identified in different photographic fields defined by a transparent grid placed over two standard 60 degrees fields. RESULTS Testing of 45 degrees macular fields disclosed 59/81 (73%), 50/81 (62%) and 64/81 (79%), respectively, of NVEs detected in a 60 degrees fovea-centred photograph. Kappa values for detecting at least one NVE, when present, were 0.62 (95% CI 0.40-0.83), 0.38 (95% CI 0.19-0.57) and 0.83 (95% CI 0.62-0.99). The corresponding figures when compared with two-field 60 degrees photography were 59/111 (53%), 50/111 (45%) and 64/111 (58%), respectively. One macula-centred 60 degrees field disclosed 81/111 (73%) of NVEs detected by 60 degrees two-field photography with an additional optic disc-centred field. Two-field 45 degrees photography disclosed 86/111 (77%) of NVEs detected by two-field 60 degrees photography. A total of 90% of NVEs detected in the optic disc-centred 60 degrees field only were also detected in the corresponding 45 degrees field. CONCLUSION One-field 45 degrees photography cannot be recommended as a screening method for diabetic retinopathy. Two-field 45 degrees photography (macula-centred and disc-centred fields) disclosed 77% of NVEs detected by the corresponding two-field 60 degrees photography.
