Abstract: The occurrence of choroidal detachment is mainly related to decreased intraocular pressure, choroidal circulation disorders, and choroidal inflammation. The reasons for secondary choroidal detachment after glaucoma surgery include the use of preoperative antiglaucoma drugs, postoperative low intraocular pressure, the use of anti-metabolic drugs, systemic factors, etc. The reasons for secondary choroidal detachment after vitrectomy surgery include surgical operation issues, properties of intraoperative vitreous cavity filling, application of fundus laser, incision leakage, etc. The reasons for secondary choroidal detachment after scleral buckling surgery include high myopia, tight pressure during buckling, and posterior positioning. There have also been cases of secondary choroidal detachment during intravitreal injection. This review aims to enhance the understanding of choroidal detachment among ophthalmologists, thereby facilitating preventive measures to mitigate its occurrence.(Int Rev Ophthalmol, 2024, 48:  460-463)
