Aqueous humor is the product of the ciliary body. It provides nutrition for the iris, cornea, lens, and trabecular meshwork. Compared to the blood, the aqueous humor can better reflect the intraocular environment. Therefore, the detection of cytokines in the aqueous humor has become one of the hot topics in ophthalmology in recent years. Altered cytokine levels in the aqueous humor have been observed in many ocular diseases, including glaucoma. Some investigators hypothesized that cytokines in the aqueous humor are associated with the pathophysiology of glaucoma, and even affect the prognosis of glaucoma filtering surgery. In this paper, the changes of several cytokines in the aqueous humor of glaucoma eyes were summarized, and the relationship between them was analyzed.
