OBJECTIVE We studied the results and complications of silicone oil removal applying basic criteria for the selection of eyes. METHODS The criteria for oil removal: 1. Completely attached retina for at least 4 weeks, 2. Absence of tractions and active proliferations, 3. Preoperative vision > 0.01. The oil was removed from 90 of 261 oil filled eyes (removal rate: 34.5%). 83 eyes were included in the further study. RESULTS 1.3-62.5 months (mean 15.7). RESULTS Visual acuity improved (> or = 1 line) in 40 of the 83 eyes (48.2%), remained unchanged in 22 eyes (26.5%) and deteriorated (> or = 1 line) in 21 eyes (25.3%). RESULTS reproliferations (42.2%), retinal detachment (20.5%), pressure rises (27.7%), lens opacification (36.7%), severe keratopathy (8.4%). CONCLUSIONS Silicone oil removal has a distinct rate of complications, despite preoperative selection of eyes with a better prognosis. Reduction of reproliferations and weighing of risk and benefit could improve the results.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
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.

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).

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
