purpose : to compare changes in posterior corneal elevation, anterior chamber depth (acd), anterior chamber volume (acv) and corneal volume (cv) after laser in situ keratomileusis (lasik ) and photorefractive keratectomy (prk) for low to moderate myopia by pentacam imaging methods : in this prospective comparative case series, 105 consecutive myopic eyes randomly scheduled for lasik (n=59) or p...

conclusions while the crp value was in patients with acute brucellosis in the current study, the mpv, rdw and leukocyte counts were within the normal range. crp value remains the most valuable inflammatory marker in cases of acute brucellosis. results the follow-up within the year after treatment was examined. the values of age, gender, leukocyte count, c-reactive protein, rdw and mpv were reco...

PURPOSE To investigate the effect and safety of a selective Rho kinase inhibitor, ripasudil 0.4% eye drops, on corneal endothelial cells of healthy subjects. DESIGN Prospective, interventional case series. METHODS In this study, 6 healthy subjects were administered ripasudil 0.4% in the right eye twice daily for 1 week. Morphological changes and corneal endothelial cell density were examine...

abstract soil quality is an essential concept for maximum agriculture production without environmental destruction. studying soil physical quality indicators, that express soil structural stability and soil air-water balance in root zone, is one of the most important aspects of soil quality. so determination of optimal range for pore volume distribution is important and this research carried ou...

Purpose The purpose of the study is to understand how extracellular stresses, such as ultraviolet (UV) irradiation, affect corneal epithelial cells. Cell volume changes, damage to corneal epithelial integrity, and cellular responses were assessed after exposure to UVC stresses. Methods Primary human and rabbit corneal epithelial cells were exposed to UVC light in culture conditions. Ultraviol...

We evaluated the change in tear film lipid layer thickness, corneal thickness, volume and topography after superficial cauterization of symptomatic conjunctivochalasis. Bilateral superficial conjunctival cauterization was performed in 36 eyes of 18 patients with symptomatic conjunctivochalasis. The mean age of patients (12 males, 6 females) was 68.6 ± 10.9 years (range: 44-83 years). Preoperati...

PURPOSE To investigate the detailed distribution of corneal epithelial thickness in single sectors and its correlated characteristics in myopic eyes. METHODS SD-OCT was used to measure the corneal epithelial thickness distribution profile. Differences of corneal epithelial thickness between different parameters and some correlations of characteristics were calculated. RESULTS The thickest a...

PURPOSE To analyze single session, intrauser reliability of a Scheimpflug device for anterior chamber (AC) and corneal parameters. METHODS In this observational study, 100 normal candidates underwent Scheimpflug analysis with Sirius 3D Rotating Scheimpflug Camera and Topography System (Costruzione Strumenti Oftalmici, Italy). Two scans in dark room conditions were performed by the same experi...
