Background : Posterior corneal elevation changes are keys to early diagnosis of corneal ectasia after keratorefractive surgery, so it is important to use an accurate method for measuring posterior corneal elevation. The purpose of this study is investigating posterior corneal elevation changes with Pentacam(HR) on patients underwent photorefractive keratectomy. Methods: In this clinical tri...
Several surgical strategies have been proposed to improve visual function in patients with keratoconus who become contact lens intolerant1,2. In mild-tomoderate keratoconus, when the central cornea remains clear, intrastromal corneal ring segments (ICRS), and phakic intraocular lenses (PIOLs) may provide enough BSCVA, and sometimes uncorrected visual acuity (UCVA), to postpone and sometimes avo...
Mesalamine-containing products are often a first-line treatment for ulcerative colitis. Severe adverse reactions to these products, including cardiovascular toxicity, are rarely seen in pediatric patients. We present a case of a 16-year-old boy with ulcerative colitis treated with Asacol, a mesalamine-containing product, who developed sudden onset chest pain after four weeks on therapy. Serial ...
INTRODUCTION Watermelon stomach (WS) or gastric antral vascular ectasia (GAVE) is a rare cause of upper gastrointestinal bleeding described in a variety of autoimmune disorders. Association of watermelon stomach with Sjögren's syndrome is extremely rare. CASE REPORT; We presented a 67-year old female with primary Sjögren's syndrome (SS) who had developed a persistent severe iron-deficiency anem...
Corneal ectasia, a weakening of corneal integrity, occurs both due to acquired and congenital conditions such as keratoconus. It is a progressing condition that affects both visual acuity, and corneal stability. Various methods exist for correcting this impairment, however none address the inherit pathology, an increase laxity of the corneal stroma. Collagen cross-linking, a new, minimally inva...
