Aside from the distinction between old hemorrhages and pigmented changes of the ocular fundus, the use of metaspectrophotography of the eye with the Kodak Ektrachrome Infrared Film IE 135-20 can be extended successfully to other fields of ophthalmological photography. By shifting the spectral range used for photography towards near infrared and cutting off the short wavelenght part by a yellow filter, spoiling scattering is avoided up to 98 percent. Thus clear goniophotography is rendered possible even with higher magnification. Better pictures are achieved in photography of the periphery of the ocular fundus, of the fundus of eyes with moderate opacity of the cristalline lens, of juvenile macular degeneration, and of pigmented areas of the iris suspected to be tumorous.
除了区分眼底陈旧性出血和色素沉着变化外,使用配备柯达埃克塔克罗姆红外胶片IE 135 - 20的眼部超分光摄影技术可成功扩展到眼科摄影的其他领域。通过将摄影所用光谱范围向近红外方向移动,并使用黄色滤光片切断短波部分,可避免高达98%的有害散射。这样,即使在更高放大倍数下也能进行清晰的前房角摄影。在眼底周边、晶状体中度混浊的眼底、青少年黄斑变性以及疑似肿瘤的虹膜色素沉着区域的摄影中能获得更好的照片。
