Trimeresurus macrops is a venomous pit viper species endemic to Southeast Asia.

[6] It can be distinguished from other green pit vipers by the relatively large size of its eyes, which is especially noticeable in adult specimens, and to which the specific name, macrops, refers.

[3] According to Strine, Green pit vipers mate during the end of the rainy season, between September and October.

It is found in Southeast Asia in northern Cambodia, Laos, Thailand, and southern Vietnam.

[2] T. macrops belongs to the genus Trimeresurus, a group of Asian vipers with primarily hemotoxic venom — a type of venom that can destroy blood cells, disrupt blood clotting, and damage organ function.
