Primary surgical repair of severe peripheral marginal ectasia in Terrien's marginal degeneration. 1984

D R Caldwell, and M S Insler, and G Boutros, and T Hawk

We have developed a safe, successful, and simple procedure for repairing the severe peripheral marginal ectasia in Terrien's marginal degeneration. The area of ectasia is incised along its thinnest paralimbal dimension down to Descemet's membrane. Ectatic stroma along both sides of the incision is then undermined until normal-thickness stroma is reached. After excision of excess ectatic stroma, if necessary, the normal-thickness stroma is then sutured together, primarily with 9-0 Prolene. The sutures are left in place permanently, and the remaining refractive error is corrected with spectacles or contact lenses. This technique substantially improved visual acuity in three of four patients and decreased corneal astigmatism in all four. Although one eye required resuturing, there were no complications in any case.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.

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
