The authors evaluate the results of ultrasound examination of 20 patients with retinal detachment (20 eyes) after pars plana vitrectomy with silicone oil tamponade. Ultrasound diagnostic method is necessary in cases with non-transparent optic media. Silicone oil in the space of vitreous cavity has a character of a swimming water-drop and his physical properties can change the echography results. Between the eye-wall and silicone oil is a virtual space, which could be well visualised by ultrasound. The patients are divided into 2 groups. In the 1st group there were 7 eyes with transparent optic media and retina was detached under the silicone oil. By ultrasound the retina detachment echo was localised between the echos of silicone oil and eye wall. In the 2nd group there were 13 eyes with non-transparent optic media. In 6 cases (41.6%) the retinal detachment echo was visualised. The retinal detachment was confirmed by vitreo-retinal surgery.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
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.

D012827	Silicone Oils	Organic siloxanes which are polymerized to the oily stage. The oils have low surface tension and density less than 1. They are used in industrial applications and in the treatment of retinal detachment, complicated by proliferative vitreoretinopathy.	Silicone Oil,Oil, Silicone
D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
