OBJECTIVE To summarize the recent literature regarding descemetorhexis stripping without endothelial keratoplasty (DWEK), increasingly referred to as Descemet's stripping only (DSO). To report the characteristic clinical, confocal and histologic findings associated with this procedure. RESULTS Reported clearance rates following DSO range from 63 to 100% in recent series, with variation between surgical techniques. Topical Rho-kinase inhibitor has been reported as successfully salvaging failing cases. Its use as an adjuvant to the surgery is gaining widespread adoption with the results of early series now arriving. Apart from a phenotype of central guttata with clear periphery, patient characteristics which determine success remain elusive. Surgical factors affecting success are increasingly well understood, with stromal injury felt to be a retardant to healing. Characteristic clinical signs have been observed and are described herein. Clinical, confocal and light microscopic images are obtained from patients in clinical trials of DSO with ripasudil. CONCLUSIONS DSO is gaining acceptance as a surgical option for a subset of patients with Fuchs' Dystrophy. The addition of Rho-associated kinase inhibitor appears to improve predictability but further results to this effect must be published and scrutinized.

D007546 Isoquinolines A group of compounds with the heterocyclic ring structure of benzo(c)pyridine. The ring structure is characteristic of the group of opium alkaloids such as papaverine. (From Stedman, 25th ed)
D003886 Descemet Membrane A layer of the cornea. It is the basal lamina of the CORNEAL ENDOTHELIUM (from which it is secreted) separating it from the CORNEAL STROMA. It is a homogeneous structure composed of fine collagenous filaments, and slowly increases in thickness with age.

D005642 Fuchs' Endothelial Dystrophy Disorder caused by loss of endothelium of the central cornea. It is characterized by hyaline endothelial outgrowths on Descemet's membrane, epithelial blisters, reduced vision, and pain.

D013449 Sulfonamides A group of compounds that contain the structure SO2NH2. Sulfonamide,Sulfonamide Mixture,Sulfonamide Mixtures,Mixture, Sulfonamide,Mixtures, Sulfonamide
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
D054460 rho-Associated Kinases A group of intracellular-signaling serine threonine kinases that bind to RHO GTP-BINDING PROTEINS. They were originally found to mediate the effects of rhoA GTP-BINDING PROTEIN on the formation of STRESS FIBERS and FOCAL ADHESIONS. Rho-associated kinases have specificity for a variety of substrates including MYOSIN-LIGHT-CHAIN PHOSPHATASE and LIM KINASES. rho-Associated Kinase,ROCK Protein Kinases,ROCK-I Protein Kinase,ROCK-II Protein Kinase,ROK Kinase,p160 rhoA-Binding Kinase ROKalpha,p160ROCK,rho-Associated Coiled-Coil Containing Protein Kinase 1,rho-Associated Coiled-Coil Containing Protein Kinase 2,rho-Associated Coiled-Coil Kinase,rho-Associated Kinase 1,rho-Associated Kinase 2,rho-Associated Kinase alpha,rho-Associated Kinase beta,rho-Associated Protein Kinase alpha,rho-Associated Protein Kinase beta,rho-Kinase,Coiled-Coil Kinase, rho-Associated,Protein Kinases, ROCK,ROCK I Protein Kinase,ROCK II Protein Kinase,p160 rhoA Binding Kinase ROKalpha,rho Associated Coiled Coil Containing Protein Kinase 1,rho Associated Coiled Coil Containing Protein Kinase 2,rho Associated Coiled Coil Kinase,rho Associated Kinase,rho Associated Kinase 1,rho Associated Kinase 2,rho Associated Kinase alpha,rho Associated Kinase beta,rho Associated Kinases,rho Associated Protein Kinase alpha,rho Associated Protein Kinase beta,rho Kinase
D057111 Descemet Stripping Endothelial Keratoplasty A surgical procedure or KERATOPLASTY involving selective stripping and replacement of diseased host DESCEMET MEMBRANE and CORNEAL ENDOTHELIUM with a suitable and healthy donor posterior lamella. The advantage to this procedure is that the normal corneal surface of the recipient is retained, thereby avoiding corneal surface incisions and sutures.
