purpose: to detect the prevalence of dry eye after vitrectomy and its influencing factors. methods: schirmer i, tear basic secretion test and tear breakup time was done preoperatively and 3 months postoperatively on consecutive patients undergoing vitrectomy in khatam hospital from 2005 to 2006. eyes with previous peritomies of more than 120◦ and symptoms of dry eye or tear tests compatible wit...

INTRODUCTION An outpatient transoral endoscopic procedure for gastroesophageal reflux disease (GERD) and obesity would be appealing if safe, effective, and durable. We present the first in human experience with a new system. METHODS Eight patients with GERD (3) and obesity (5) were selected according to a preapproved study protocol. All GERD patients had preprocedure manometry and pH monitori...

A best evidence topic was written according to the structured protocol. The three part question addressed was: [In patients undergoing closure of surgical wounds with sutures] does [keeping the wound dry for the first 48 h after closure] [reduce the incidence of surgical site infections (SSIs)]? 4 relevant papers were culled from the literature and appraised. The authors, date, country, populat...

In this paper we construct a Floer-homology invariant for a natural and wide class of sutured manifolds that we call balanced. This generalizes the Heegaard Floer hat theory of closed three-manifolds and links. Our invariant is unchanged under product decompositions and is zero for nontaut sutured manifolds. As an application, an invariant of Seifert surfaces is given and is computed in a few i...

Objectives To investigate corneal, scleral, choroidal, and foveal thicknesses in female patients with rheumatoid arthritis (RA) and compare them with healthy subjects. Materials and Methods This prospective study included consecutive female patients diagnosed with RA and healthy subjects. Corneal, scleral, choroidal, and retinal (foveal) thicknesses were obtained by using optical coherence to...

PURPOSE To describe a new surgical approach for the tectonic reconstruction of the anterior ocular segment and the management of scleral and conjuctival melting. METHODS Case series of patients demonstrating anterior segment anomalies, such as scleral and conjunctival melting. The anterior stromal part of a pre-cut corneal graft for Descemet's stripping automated endothelial keratoplasty (DSA...

normal 0 false false false en-us x-none ar-sa background: we aimed to compare peak systolic velocity of central retinal artery (psv.cra) and peak systolic velocity of ophthalmic artery (psv.oa) between patients with retinal detachment who were treated with segmental scleral bucking and scleral buckling with encircling procedure. materials and methods: this study was a descriptive-analytic cross...
