Infrared (IR) irradiation is frequently used in ophthalmological diagnosis and treatment. It has been used to selectively stimulate photodiode-based retinal prostheses to prove their function. Data concerning the natural IR-sensitivity of the retina are contradictory. In our experiments in dark-adapted cats an IR-laser (826 nm) and IR emitting diodes (875 nm) elicited clear scotopic threshold responses. Comparison of the two lasers (IR and a visible laser at 670 nm) using Lambs template and our experimental data revealed very similar differences in retinal sensitivity (4.28 and 3.94+/-0.29 log units, respectively). The fact that the cat retina is sensitive to IR-irradiation under certain conditions has important implications in interpreting the results from retinal prostheses and rewards further attention in its use in many ophthalmological applications.
红外（IR）照射常用于眼科诊断和治疗。它已被用于选择性刺激基于光电二极管的视网膜假体以证明其功能。关于视网膜天然红外敏感性的数据相互矛盾。在我们对暗适应猫的实验中，红外激光（826纳米）和红外发光二极管（875纳米）引发了明显的暗视阈值反应。使用兰姆模板和我们的实验数据对两种激光（红外激光和670纳米的可见激光）进行比较，结果显示视网膜敏感性的差异非常相似（分别为4.28和3.94±0.29对数单位）。猫视网膜在某些条件下对红外照射敏感这一事实，对于解释视网膜假体的结果具有重要意义，并且在其在许多眼科应用中的使用方面值得进一步关注。
