Purpose: To search evidence and determine whether PRK (Photo Refractive Keratectomy) or LASIK (Laser in Situ Keratomileusis) produce a better outcome of laser vision correction for patients with atypical topography of cornea. Setting: Electronic search of laser vision correction related studies on Cochrane Library, Medline and PubMed. Method: The search was conducted over Cochrane Library, Emba...

The etiology of gastric antral vascular ectasia (GAVE) and hyperplastic polyps (HP) is not fully understood, but there is no known overlap. We report a case of gastroduodenal HP arising in a patient treated for GAVE.

Spinal reconstruction with pedicle screw-based instrumentation and rhBMP-2 in patients with neurofibromatosis and severe dural ectasia and spinal deformity: Report of two cases and a review of the literature.

Gastric antral vascular ectasia ('water melon stomach') is a poorly documented cause of occult upper gastrointestinal blood loss. We describe a case which emphasises the clinical and pathological difficulties that can be encountered in making this elusive diagnosis.

PURPOSE A preliminary study to evaluate the outcomes of high-resolution wavefront-guided (HRWG) photorefractive keratectomy (PRK) with simultaneous corneal cross-linking (CXL) in ectasia eyes. METHODS Sixteen eyes of 11 patients (mean age 31.9±9.8 years; range: 15-48 years) with keratoconus or post-laser-assisted in situ keratomileusis ectasia underwent HRWG PRK with simultaneous CXL. Manifes...

PURPOSE To differentiate between keratoconus and contact lens-related corneal warpage by combining focal change patterns in anterior corneal topography, pachymetry, and epithelial thickness maps. METHODS Pachymetry and epithelial thickness maps of normal, keratoconus, and warpage, and forme fruste keratoconus (FFK) eyes were obtained from a Fourier-domain optical coherence tomography (OCT). E...

PURPOSE The objective of this study is to describe the authors' results with intrastromal corneal ring segments (Intacs) and a new variation of lamellar keratoplasty, termed intralamellar keratoplasty (ILK), for the treatment of keratoconus (KCN) and post-laser-assisted in situ keratomileusis (LASIK) ectasia. METHODS A retrospective review of contact lens-intolerant KCN and post-LASIK ectasia...

Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the le...

Francois Malecaze MD commenced the session with an update on current research into the genetics of keratoconus. Dr Malecaze noted that forme fruste keratoconus is one of the major causes of post-LASIK corneal ectasia and the condition may be due to genetic factors in the majority of cases. Identification of the gene or genes responsible for keratoconus might lead to the development of blood tes...
