[Treatment of retinal detachment caused by posterior pole dehiscence]. 1985

P Girard, and F Navarro, and C Boscher, and P Mercier

20 eyes have been treated for a retinal detachment due to a posterior pole break. Three successive, different operative techniques were used: macular silastic sponge, vitrectomy plus internal tamponade by silicone oil, vitrectomy plus internal tamponade by air or by a mixture of air 60% and SF6 40%. Macular sponges obtained a good rate of retinal reattachment (83.3%) but fonctionnal results are poor (no measurable visual acuity in the macular break cases). Vitrectomy plus silicone oil does not yield better anatomical results than sponges (66.6% succes rate) but the visual function is better preserved (2 measureable visual acuities on 3 macular break cases). Vitrectomy plus gas gave us the best anatomical (100% success rate) and functional results (4 measurable usual acuities on 6 macular break cases). Retinopexy is not necessary when the vitrectomy-gas technique is used. On the contrary, retinopexy is recommended when the vitrectomy-silicone technique is used in order to remove the silicone oil as safely as possible: this causes a dilemma in the case of a macular break. We think at the present time that vitrectomy-gas is the best way to treat these particular retinal detachments.

D008722	Methods	A series of steps taken in order to conduct research.	Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
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.

D012826	Silicone Elastomers	Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.	Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
D012828	Silicones	A broad family of synthetic organosiloxane polymers containing a repeating silicon-oxygen backbone with organic side groups attached via carbon-silicon bonds. Depending on their structure, they are classified as liquids, gels, and elastomers. (From Merck Index, 12th ed)	Silicone
D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
D014821	Vitrectomy	Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.	Vitrectomies
