Keratoconus is a condition characterized by biomechanical instability of the cornea, presenting in a progressive, asymmetric and bilateral way. Corneal collagen cross-linking with riboflavin and UVA (CXL) is a new technique of corneal tissue strengthening that combines the use of riboflavin as a photo sensitizer and UVA irradiation. The studies showed that CXL was effective in halting the progr...

PURPOSE To investigate the efficacy of the SCORE Analyzer (Bausch+Lomb TechnoLas, Germany) in detecting forme fruste keratoconus (FFKC) in Asian eyes and validate its usefulness as a risk assessment system for post-laser in situ keratomileusis (LASIK) keratectasia. METHODS We retrospectively evaluated corneal topographies with the Orbscan IIz system and independently tested them with the SCOR...

iatrogenic dissections of the ascending aorta are an uncommon and severe complication during cardiac catheterization. a 68-year-old female patient underwent diagnostic cardiac catheterization due to non-st-elevation myocardial infarction. during the procedure, a catheter-induced 360 • class i dissection of the right coronary artery occurred. the patient developed severe bradycardia, which was t...

pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. as a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. here we report a case...

vascular injuries with acute or chronic arterial hemorrhage after femoral shaft fractures are a rare but a life-threatening complication. we observed a case of iatrogenic rupture of the profunda femoris artery after the internal fixation of a femoral shaft fracture. the pseudoaneurysm, presenting with painful expansile swelling and hemodynamic instability, together with the rupture was evident ...

purpose: to report a case who had undergone lasik in his right eye and prk in the fellow eye for correction of equivalent myopia but developed progressive post-operative keratectasia only in the right eye. patient and findings: a 30-year-old man had undergone lasik in right eye 3 years ago for correction of refractive error of -1.75  -1.50@48° and prk in left eye 2 years ago for correction of r...

We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK) in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acui...
