A wide-angle funduscopic lens was used to take slit-lamp photographs of the posterior vitreous. The lens was then evaluated for its optics, magnification, field of view, and photographic usefulness and compared with the photographs taken using double aspheric preset lenses. The advantages of the wide-angle funduscopic lens were its wider field of view and ability to photograph the vitreous in the presence of a small pupil and cataract. The drawbacks were the darker image, low magnification, and artifactitious light reflection from the lens. The slit-lamp photographs using the wide-angle funduscopic lens were very useful in some complicated cases.
使用广角眼底镜镜头拍摄玻璃体后部的裂隙灯照片。然后对该镜头的光学性能、放大倍数、视野和摄影实用性进行评估，并与使用双非球面预设镜头拍摄的照片进行比较。广角眼底镜镜头的优点是视野更宽，能够在瞳孔较小和存在白内障的情况下拍摄玻璃体。缺点是图像较暗、放大倍数低以及镜头产生的伪像光反射。在一些复杂病例中，使用广角眼底镜镜头拍摄的裂隙灯照片非常有用。
