PURPOSE Posterior Polymorphous Dystrophy (PPCD) is a genetically heterogeneous corneal dystrophy, with linkage to three different chromosomal loci, with several genes in these loci being implicated. The role of both VSX1 and COL8A2 in PPCD remains controversial but recent work suggests that mutations in the transcription factor gene ZEB1/TCF8 account for(More)
PURPOSE Mutations in the visual system homeobox 1 (VSX1) gene have been described at a low frequency in keratoconus and posterior polymorphous corneal dystrophy (PPCD). The putative role is controversial for several reasons, including a lack of mutations detected in other population cohorts. This study aims to determine whether VSX1 contributes to the(More)
PURPOSE Corneal dystrophy of Bowman's layer (CDB) belongs to a group of dystrophies associated with mutations in the transforming growth factor-beta-induced (TGFBI) gene. CDB is further divided into a geographic variant (CDB1/Reis Bücklers, RBCD), and a honeycomb variant (CDB2/Thiel Behnke, TBCD). We undertook mutational analysis of TGFBI in a family with(More)
PURPOSE With advances in phenotyping tools and availability of molecular characterization, an increasing number of phenotypically and genotypically diverse inherited corneal dystrophies are described. We aimed to determine the underlying causative genetic mechanism in a three-generation pedigree affected with a unique anterior membrane corneal dystrophy(More)
A 28-year-old female with a history of contact lens wear presented with a 1 week history of pain and photophobia in her left eye. In vivo confocal microscopy (IVCM) and corneal scrape confirmed the diagnosis of Acanthamoeba keratitis (AK) which was treated with intensive topical propamidine isethionate (0.1%) and chlorhexidine (0.02%) with tapering dosage(More)
This review highlights many of the fundamental concepts and events in the development of corneal transplantation - from ancient times to modern. Tales of eye, limb, and even heart transplantation appear in ancient and medieval texts; however, in the scientific sense, the original concepts of corneal surgery date back to the Greek physician Galen (130-200(More)
