A major physiologic role for the high flow choroidal vasculature is to help maintain a stable temperature in the macula. The choroidal vasculature modulates tissue temperature in the macula via both active and passive mechanisms. The active mechanisms involve a reflexive increase in choroidal blood flow in response to light. The neuro-anatomical pathways mediating this reflective mechanism have been demonstrated to involve the supra-chiasmatic and the Edinger-Westphal nuclei. The importance of the thermal environment for the retina has been neglected in looking for causes of retinal disease. The observations on the ability of the choroidal circulation to modulate the thermal environment of the macula should excite further study of the role of temperature and the ability of the eye to dissipate light-generated heat on macula disease.
高流量脉络膜血管系统的一个主要生理作用是帮助维持黄斑区的稳定温度。脉络膜血管系统通过主动和被动机制调节黄斑区的组织温度。主动机制包括在光照下脉络膜血流反射性增加。介导这种反射机制的神经解剖学途径已被证明涉及视交叉上核和动眼神经副核。在寻找视网膜疾病的病因时，视网膜热环境的重要性一直被忽视。关于脉络膜循环调节黄斑区热环境能力的观察结果，应该会激发人们进一步研究温度的作用以及眼睛在黄斑疾病中消散光产生热量的能力。
