background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...
Introduction & Objective: Corneal ulcer is one of the most important medical emergencies that in the absence of on time diagnosis and treatment can lead to loss of vision. Therefore, identification of microorganisms and their response to drugs in each region is important. The aim of this study was to determine the most common organisms that cause keratitis and antibiotic sensitivity in this reg...
In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...
Objectives. Ultrasonography (US) is a sensitive tool for detecting erosions in patients with RA. The wrist is usually involved in the RA process, where the distal ulna with its superficial localization is easily accessible for US examination. In this longitudinal study, we wanted to examine the presence, localization and development of erosions at the distal ulna by US in patients with recent o...
Diabetes mellitus has been identified as a risk factor for dry eye syndrome (DES). The prevalence of DES in diabetes has been reported to be up to 54.3% (1). DES compromises quality of life because it induces ocular discomfort and visual disturbance and may be complicated by corneal epithelial defects, erosions, or ulcers. Therefore, it is recognized as a growing public health problem that shou...
PURPOSE To determine the morphologic features of the epithelium and extracellular matrix in spontaneous chronic corneal epithelial defects (SCCED) in dogs. METHODS Forty-eight superficial keratectomy specimens were obtained after confirmation of the presence of a superficial corneal erosion for longer than 3 weeks with no discernible underlying cause. Histologic samples were examined by light...
OBJECTIVE To assess the ability of ultrasonography (US) to predict radiographic damage in early arthritis. METHODS ESPOIR is a multicentric cohort of early arthritis (i.e., ≥2 swollen joints between 6 weeks and 6 months). US synovitis in B mode, power Doppler (PD) mode, and erosions were searched on the second through the fifth metacarpophalangeal and fifth metatarsophalangeal joints accordin...
Background and Objective: Keratoconus is a disorder in cornea characterized by constant thinning and prominence that can result in vision defect. Due to ultrasonic changes in the corneal structure caused by keratoconus disease, its rigidity and biomechanical properties are subject to some changes. In this regard, the present study was conducted to determine the correlation of biomechanical feat...
BACKGROUND The objectives of the present study were, with multidetector computed tomography (CT) as the reference method, to determine the performance of magnetic resonance imaging (MRI) and radiography for the detection of bone erosions in rheumatoid arthritis wrist bones, and to test whether measuring volumes of erosions on CT and MRI is reproducible and correlated to semiquantitative assessm...
