In the current study, we conducted a mutation screening of tumor-associated calcium signal transducer 2 (TACSTD2) gene in six consanguineous Iranian families with gelatinous drop-like corneal dystrophy (GDLD), in order to find the causative mutations. Detailed eye examination was performed by ophthalmologist to confirm GDLD in patients. To detect the possible mutations, direct Sanger sequencing...
Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal,...
purpose: to evaluate changes in indications of corneal transplantation at labbafinejad medical center during 2001-2003. methods: records of 563 from 684 patients who had undergone corneal transplantation from oct. 2001 to oct. 2003 were evaluated. all the procedures were performed by corneal surgeons and fellows. findings: there were 292 male (51.9%) and 217 female (48.1%) subjects ranging in a...
purpose : the aim of this study was to determine indications of keratoplasty during 7 years (1999–2006) in emam-rreza and vali-asr teaching hospitals of birjand university of medical sciences. methods : medical records of all patients who underwent penetrating keratoplasty (pk) in teaching hospitals of birjand university of medical sciences from 1999 to 2006 were investigated retrospectively. t...
The pertinent literature on inherited corneal diseases is reviewed in terms of the chromosomal localization and identification of the responsible genes. Disorders affecting the cornea have been mapped to human chromosome 1 (central crystalline corneal dystrophy, familial subepithelial corneal amyloidosis, early onset Fuchs dystrophy, posterior polymorphous corneal dystrophy), chromosome 4 (Biet...
purpose: to compare clinical and confocal scan outcomes after descemet stripping automated endothelial keratoplasty (dsaek) performed for fuchs’ endothelial dystrophy versus pseudophakic bullous keratopathy. methods: in this retrospective comparative study, 47 consecutive eyes of 39 patients with the diagnosis of fuchs’ endothelial dystrophy (n=29, group 1) or pseudophakic bullous keratopathy (...
Author response: prevalence of corneal dystrophies in the United States: estimates from claims data.
PURPOSE To estimate the prevalence of corneal dystrophies. METHODS Records of almost 8 million enrollees in a national managed-care network throughout the United States who had an eye care visit in 2001 to 2009 were searched for a recording of corneal dystrophy on a claim submitted by an ophthalmologist or optometrist from January 1, 2001, through December 31, 2007. RESULTS Unique individua...
AIMS To investigate the frequency of corneal guttata in patients with a corneal dystrophy resulting from an Arg124His (R124H) mutation of betaig-h3 gene. METHODS Slit lamp examination was performed on 30 eyes with corneal dystrophy from a genetically confirmed betaig-h3 R124H mutation and on 50 age matched control eyes. The stage of the corneal dystrophy was classified as stage 0, I, or II an...
PURPOSE To update the 2008 International Classification of Corneal Dystrophies (IC3D) incorporating new clinical, histopathologic, and genetic information. METHODS The IC3D reviewed worldwide peer-reviewed articles for new information on corneal dystrophies published between 2008 and 2014. Using this information, corneal dystrophy templates and anatomic classification were updated. New clinic...
INTRODUCTION Corneal dystrophy is defined as bilateral and symmetric primary corneal disease, without previous associated ocular inflammation. Corneal dystrophies are classified according to the involved corneal layer in superficial, stromal, and posterior dystrophy. Incidence of each dystrophy varies according to the geographic region studied. PURPOSE To evaluate the prevalence of stromal co...
