Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by severe itching and recurrent eczema-like lesions. With the increase in the global incidence of AD, the incidence of ocular complications in patients also increases. Retinal detachment (RD) seriously affects the vision of patients, and is more common in young and middle-aged people, often involving both eyes with poor prognosis. What’s more, there are many similarities between RD associated with AD and traumatic RD, such as peripheral retinal breaks, giant retinal tears and retinal dialysis. Regarding the mechanism of AD complicated with RD, the trauma theory is widely accepted. Scholars have also reported on the theory of anterior eye developmental abnormalities, inflammation-traction theory, and ectodermal origin theory. On AD complicated with RD, regardless of scleral buckling surgery or vitrectomy surgery, the rate of first retinal reattachment is low with severe proliferative vitreoretinopathy or chronic uveolar inflammation after surgery, which cause traction on the ciliary body and the retina separation appearance again or new cracks appearance. Combination of behavioral therapy, drug therapy and psychotherapy can effectively reduce the occurrence of RD; prevention of eye rubbing, reduction of traumatic exercise, rational use of glucocorticoids or immunosuppressants under the guidance of dermatologists are effective ways for AD patients to prevent RD occurrence. Regular eye examinations can help patients find RD as soon as possible so that they can be treated in time.
