To compare nurse-guided Optomap retinal imaging with examination by an eye casualty officer, in detecting clinically significant peripheral retinal lesions in patients with retinal symptoms.
219 patients presenting to eye casualty with retinal symptoms (flashing lights and floaters) were recruited. Retinal images were taken with the Optomap imaging system, and graded by an independent masked ophthalmologist. The findings from the Optomap and casualty officer were compared with a gold-standard examination with scleral indentation performed by a retinal specialist. We calculated the sensitivity and specificity of the Optomap and casualty officer.
The final analysis included 205 eyes of 187 patients. The sensitivity of the Optomap for detecting retinal detachment (n = 7) was 100% (95% CI 59-100%), the same as the casualty officer. For retinal holes/tears (n = 18) the Optomap sensitivity was 33% (13-59%), compared with 67% (41-87%) for the casualty officer. Combining all retinal lesions (n = 52), the sensitivity was 62% (47-75%) and 73% (59-84%), with specificity 96% (92-99%) and 98% (94-100%) for the Optomap and casualty officer respectively.
The Optomap detects retinal detachments successfully but, due to limitations in the optics, is not able to accurately detect retinal holes and tears.
比较护士指导下的Optomap视网膜成像与眼科急诊医生检查在检测有视网膜症状患者的临床显著性周边视网膜病变方面的效果。
招募了219名因视网膜症状(闪光和飞蚊症)前来眼科急诊的患者。使用Optomap成像系统拍摄视网膜图像,并由一名独立的蒙面眼科医生进行分级。将Optomap和急诊医生的检查结果与视网膜专科医生进行巩膜压陷的金标准检查结果进行比较。我们计算了Optomap和急诊医生的敏感性和特异性。
最终分析纳入了187名患者的205只眼。Optomap检测视网膜脱离(n = 7)的敏感性为100%(95%CI 59 - 100%),与急诊医生相同。对于视网膜裂孔/撕裂(n = 18),Optomap的敏感性为33%(13 - 59%),而急诊医生为67%(41 - 87%)。综合所有视网膜病变(n = 52),Optomap的敏感性为62%(47 - 75%),急诊医生为73%(59 - 84%),特异性分别为96%(92 - 99%)和98%(94 - 100%)。
Optomap能够成功检测视网膜脱离,但由于光学方面的限制,无法准确检测视网膜裂孔和撕裂。
