The photo slit lamp has characteristics that may be important in optic disc photography for measuring glaucomatous cupping. This finding led to the question of whether disc photographs with the slit lamp showed less detail than fundus camera photographs. Tests were conducted on in-air resolution and of each instrument's ability to record fine vessel detail in normal human optic discs. The results showed that the instruments performed comparably in each test.
裂隙灯在测量青光眼视盘杯凹的视盘摄影中可能具有重要特征。这一发现引发了一个问题，即使用裂隙灯拍摄的视盘照片是否比眼底相机拍摄的照片细节更少。对两种仪器在空气中的分辨率以及记录正常人类视盘中细微血管细节的能力进行了测试。结果表明，两种仪器在每项测试中的表现相当。
