Posterior Polymorphous Corneal Dystrophy (PPCD) Combined with Traumatic Descemet's Membrane Fold

Purpose: To present a case of a 72-year-old woman with posterior polymorphous corneal dystrophy (PPCD) combined with traumatic Descemet's membrane fold due to forceps injury in Birth.Case summary: A 72-year-old woman without significant ocular history presented complaining of ocular discomfort in her right eye.She had a history of birth that required forceps delivery and poor vision in the right eye since childhood.The rest of perinatal ophthalmic history was unremarkable (no past ophthalmic or family history).The best corrected visual acuity was 20/20 in both eyes.Slit-lamp biomicroscopy showed distinctive, vertical, semitranslucent Descemet's membrane breaks situated on the superior temporal side of the posterior surface of the cornea in her right eye.Also, a horizontal, tram-track line appearance of posterior cornea surface was detected at middle and inferior side of cornea.The fellow eye was normal.The endothelial cell densities were 945 cells/mm 2 and 2481 cells/mm 2 in right and left eyes, respectively.After 11 years later, (routine follow up exams every 1 year), the endothelial cell densities were 901 cells/mm 2 and 2481 cells/mm 2 in right and left eyes, respectively, which means there were no significant changes of endothelial densities in both eyes.Conclusions: We report a case of a patient with posterior polymorphous corneal dystrophy (PPCD) combined with traumatic Descemet's membrane fold due to forceps injury in Birth.The disease does not seem to progress or aggravated in long term follow up and no specific treatment was required.
