3D ocular heat transfer analysis by infrared exposure

红外白内障的发病机制因红外波长不同而不同。红外线(IR)A(808 Nm)照射的眼部损伤发生在眼组织色素沉着部周围。眼内热传输分析表明，IR-A能量被虹膜吸收，产生热致疾病，其热量到达晶状体，导致白内障。相比之下，IR-B暴露眼的热传输路径从角膜下的右侧上升，对流下降到虹膜或晶体晶状体一侧。

The pathogenic mechanism of infrared cataract differed by infrared wavelengths. The ocular lesions by infrared (IR) A (808 nm) exposure occurred around the pigmented part in the ocular tissue. In contrast, those by the IR-B and C exposure were mainly corneal damages.The intraocular thermal transportation analysis elucidates that IR-A energy is absorbed by the iris, generating heat-induced disorders, and its heat reaches the crystalline lens and causes cataract. In contrast, the thermal transport route in the IR-B exposed eye was observed to rise from the right under the cornea and the convection descended to the iris or the crystalline lens side.
