PURPOSE To report the preliminary results of a surgical technique for transplantation of posterior corneal tissue through a sclerocorneal pocket incision for corneal endothelial disorders. DESIGN Retrospective, noncomparative, interventional cases series. PARTICIPANTS AND INTERVENTION In seven sighted human eyes, a deep stromal pocket was created across(More)
PURPOSE To report on the calibration of the Topcon SP-2000P specular microscope and the Endothelial Cell Analysis Module of the IMAGEnet 2000 software, and to establish the validity of the different endothelial cell density (ECD) assessment methods available in these instruments. METHODS Using an external microgrid, we calibrated the magnification of the(More)
PURPOSE To report endothelial cell density (ECD) after posterior lamellar keratoplasty (PLK). DESIGN Prospective, interventional case series. METHODS In a single institution, PLK was performed in 15 eyes of 15 patients with pseudophakic bullous keratopathy (PPBK), Fuchs endothelial dystrophy (FED), or both. In 11 eyes, the donor tissue was inserted(More)
PURPOSE To report the midterm endothelial cell density measurements after posterior lamellar keratoplasty (Melles techniques). DESIGN Cohort study. METHODS Fifteen consecutive eyes of 15 patients in whom a posterior lamellar keratoplasty procedure was performed for pseudophakic bullous keratopathy or Fuchs' endothelial dystrophy were evaluated. In 11(More)
PURPOSE To measure the recipient endothelial cell loss after the Melles technique for deep anterior lamellar keratoplasty. METHODS In 21 eyes of 21 patients, a deep anterior lamellar keratoplasty procedure was performed. Before surgery and at 6, 12, and 24 months after surgery, specular microscopy was performed to evaluate the endothelial cell density.(More)
OBJECTIVE To quantify the toxicity of trypan blue on human corneal cells according to exposure time and concentration. METHODS Three in vitro experiments were performed. (1) We exposed cultured human corneal fibroblasts to trypan blue (0.0001% to 0.1%) in Eagle modified minimum essential medium (EMEM) or phosphate-buffered saline (PBS) for 15 minutes to(More)
The composition of the essential oils of Senecio vulgaris, S. jacobaea, S. congestus and S. fuchsii was investigated by means of GLC, CC and GC-MS. The principal constituents differ; S. congestus: 1-tridecene and 1-undecene, S. jacobaea: germacrene D and 1-undecene, S. vulgaris: beta-caryophyllene, alpha-copaene and myrcene, S. fuchsii: anhydro-oplopanone(More)
