Simultaneous external subretinal fluid drainage and intravitreal gas injection in nonvitrectomized eyes with a special 27-gauge needle. 1986

S M Meyers, and H Zegarra, and D M Nguyen, and G J Skipper

In 12 patients with retinal detachment requiring a scleral buckle, simultaneous external subretinal fluid drainage, and intravitreal gas injection were performed to prevent "fishmouthed" retinal breaks in six patients and to achieve more complete drainage of subretinal fluid in six others with chronic inferior detachments. To simplify this technique in all of these nonvitrectomized eyes, we used a special 27-gauge needle sutured to the sclera.

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.

D004322	Drainage	The removal of fluids or discharges from the body, such as from a wound, sore, or cavity.
D005740	Gases	The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure.

D012591	Scleral Buckling	An operation for retinal detachment which reduces the size of the globe by indenting the sclera so that it approximates the retina.	Buckling, Scleral,Bucklings, Scleral,Scleral Bucklings
D014822	Vitreous Body	The transparent, semigelatinous substance that fills the cavity behind the CRYSTALLINE LENS of the EYE and in front of the RETINA. It is contained in a thin hyaloid membrane and forms about four fifths of the optic globe.
