OBJECTIVE A retrospective study was performed to determine the incidence of retinal detachment after extracapsular cataract extraction in high myopia and the risk factors associated with the occurrence of retinal detachment. METHODS Of the 463 patients (463 eyes) who had undergone extracapsular cataract extraction with or without intraocular lenses implant between July 1993 and January 1994, 90 patients companied with high myopia and the others were senior cataract. All patients had been followed up for 27 to 33 months. RESULTS One (1.11%) developed retinal detachment in the patients with high myopia, and no retinal detachment occurred in the patients with senior cataract. The difference of the incidence of retinal detachment between two groups were no significant (P > 0.05), More myopic patients underwent Nd:YAG laser capsulotomy (P < 0.05). CONCLUSIONS Comparing with intracapsular method, extracapsular cataract extraction decreased the risk of retinal detachment even in the high myopic patients. The risk factors for retinal detachment were young patients, long eye axis and posterior capsulotomy.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009216	Myopia	A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.	Nearsightedness,Myopias,Nearsightednesses
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.	Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D012163	Retinal Detachment	Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

D002386	Cataract	Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).
