Copper, although known as a micronutrient, has a pivotal role in modulating the cellular metabolism. Many studies have reported the role of copper in angiogenesis. Copper chaperones are intracellular proteins that mediate copper trafficking to various cell organelles. However, the role and function of copper chaperones in relation to angiogenesis has to be further explored. The intracellular copper levels when in excess are deleterious and certain mutations of copper chaperones have been shown to induce cell death and influence various cellular metabolisms. The study of these chaperones will be helpful in understanding the players in the cascade of events in angiogenesis and their role in cellular metabolic pathways. In this review we have briefly listed the copper chaperones associated with angiogenic and metabolic signalling and their function.

TBARS and homocysteine are known to be independent risk factors for CRVO. TBARS can be influenced by both homocysteine and TAC, thereby contributing to the aetiopathology of CRVO by increasing oxidative stress.
