Ocular damage threshold data remain sparse in the continuous wave (CW), near-infrared (NIR) radiation region save for the 1300-nm area that has been investigated in the past several decades. The 1300-nm ocular damage data have yielded unusual characteristics where CW retinal damage was observed in rabbit models, but never in nonhuman primate models. This paper reviews the existing 1300-nm ocular damage threshold data in terms of the fundamental criteria of an action spectrum to assist in explaining laser-tissue effects from near-infrared radiation in the eye. Reviewing the action spectrum criteria and existing NIR retinal lesion data lend evidence toward the significant presence of thermal lensing in ocular media affecting damage, a relatively unexplored mechanism of laser-tissue interaction.
除了在过去几十年中已被研究的1300纳米区域外,连续波(CW)近红外(NIR)辐射区域的眼部损伤阈值数据仍然稀少。1300纳米的眼部损伤数据呈现出不寻常的特征,即在兔模型中观察到连续波视网膜损伤,但在非人类灵长类动物模型中从未观察到。本文根据作用光谱的基本标准,对现有的1300纳米眼部损伤阈值数据进行了综述,以帮助解释眼睛中近红外辐射的激光-组织效应。回顾作用光谱标准和现有的近红外视网膜病变数据,为眼内介质中影响损伤的热透镜效应的显著存在提供了证据,这是一种相对未被探索的激光-组织相互作用机制。
