Corneal collagen cross-linking for keratoconic cornea pretreated with PRK.
To the Editor: We read the recent article by Tuwairqi and Sinjab,1 which appeared in the May 2012 issue of the Journal of Refractive Surgery, and would like to offer some comments. Tuwairqi and Sinjab, in this prospective and noncontrolled study, performed corneal collagen cross-linking (CXL) in patients with stage 1 or 2 keratoconus pretreated with topography-guided photorefractive keratectomy...
متن کاملTectonic Lamellar Keratoplasty Using Cryopreserved Cornea in a Large Descemetocele
We describe herein a case of an impending corneal perforation with a large descemetocele in a patient with previous penetrating keratoplasty (PKP) that subsequently was treated with an emergent lamellar keratoplasty using frozen preserved cornea. A 76-year-old male patient, who had a PKP, presented with a completely whitish and edematous graft accompanied by large epithelial defects. Although a...
متن کاملHeparanase Overexpresses in Keratoconic Cornea and Tears Depending on the Pathologic Grade
Background Keratoconus has classically been defined as a noninflammatory disorder, although recent studies show elevated levels of inflammatory markers suggesting that keratoconus could be, at least in part, an inflammatory condition. Heparanase upregulation has been described in multiple inflammatory disorders. In this article, we study the differential expression of heparanase in cornea and t...
متن کاملTelocytes in normal and keratoconic human cornea: an immunohistochemical and transmission electron microscopy study
Telocytes (TC) are typically defined as cells with telopodes by their ultrastructural features. Their presence was reported in the interstitium of various organs in vertebrates, including humans. However, no study has yet described the presence of TC in the human eye and in particular, within the stromal compartment of the cornea. To address this issue, samples of normal and pathologic (keratoc...
متن کاملDeep Anterior Lamellar Keratoplasty in Keratoconic Patients with versus without Vernal Keratoconjunctivitis
PURPOSE To compare the clinical outcomes of deep anterior lamellar keratoplasty (DALK) for keratoconus in patients with vernal keratoconjunctivitis (VKC) versus those without VKC. METHODS In this retrospective comparative study, records of 262 eyes with keratoconus (Group 1) and 28 keratoconic eyes with VKC (Group 2) that had undergone DALK were compiled. Reviewed parameters included length o...
