Cyclodialysis is a common complication of ophthalmic operation, eye blunt injury and other eye diseases. The most common clinical manifestations are vision loss, resistant low intraocular pressure,shallow anterior chamber and refractive status change,et al. Low intraocular pressure can lead to optic disc hyperaemia and edema, retinal ischemia and macular edema, if sustained low, it may cause corneal dystrophy and cataract et al and lead to irreversible visual impairment. Some serious patients may appear eye atrophy. Diagnosis and treatment on early stage are very important to reduce the complications. As the emergence of B-scan ophthalmological ultrasound, ultrasound biomicroscopy(UBM)and anterior segment-optical coherence tomography(AS-OCT), some small scale of cyclodilysist can be found in the early period, and the accuracy of diagnosis increases. With the research and exploration in recent years, the treatment of cyclodialysis has made a lot of progress.
