Simultaneous external subretinal fluid drainage and intravitreal gas injection. 1985

S M Meyers, and E J FitzGibbon

Simultaneous external subretinal fluid drainage and intravitreal gas injection was performed in 12 patients requiring a large or near-total internal gas tamponade (eight eyes with proliferative vitreo-retinopathy following vitrectomy and four eyes without proliferative vitreoretinopathy that had not undergone vitrectomy). None of the patients had a preexisting or intentional posterior retinal break. The retina was attached six or more months postoperatively in nine of the 12 patients. In one patient, an iatrogenic retinal break occurred without retinal incarceration. In selected cases, this procedure is an alternative to internal fluid-gas exchange through a posterior retinal break, thus avoiding the necessary postoperative facedown position, which is difficult for some patients to maintain. This method may also be used for preventing "fish-mouthed" retinal breaks in selected cases.

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.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
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.

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.
