Terrien's Marginal Degeneration Associated with Posterior Polymorphous Dystrophy.Wagoner, Michael D. M.D.; Teichmann, Klaus D. M.D., F.R.C.S., F.R.A.C.O.Cornea: September 1999 CASE REPORTS: PDF Only Abstract Abstract Purpose: To document an association between Terrien's marginal degeneration and posterior polymorphous dystrophy. Methods: A 23-year-old Saudi man presented with decreased vision, peripheral corneal thinning with vascularization and scarring, and abnormalities of the posterior stroma and Descemet's membrane. Results: Clinical examination, corneal topography, and specular microscopy were consistent with a diagnosis of Terrien's marginal degeneration and posterior polymorphous dystrophy. Conclusion: We report the first case, to our knowledge, of the simultaneous occurrence of Terrien's marginal degeneration with posterior polymorphous dystrophy.
