To evaluate the amount of reflux and degree pain with intravitreal injection (IVT) using 6 different types syringes/needles 5 techniques scleral incision, including 3 modifications a beveled incision.This was study conducted in 205 eyes patients. IVT bevacizumab for retinal pharmacotherapy needles incision. The severity subjectively evaluated (0-10) width subconjunctival bleb arising from vitreal reflux. Secondary outcomes were increase intraocular pressure complication rate.The straight...
Purpose: Compare depth-resolved biomechanical properties in normal and keratoconic corneas live human subjects using optical coherence elastography (OCE). Methods: In a prospective series of keratoconus (KC) eyes, corneal perturbation was applied by custom swept-source OCE system transparent flat lens coupled to force transducers. Cross-correlation track frame-by-frame OCT speckle displacement. Regional displacements for the anterior posterior stroma were plotted versus displacement (k)...
Purpose To assess depth-dependent corneal displacements in live normal subjects using optical coherence elastography (OCE). Methods A method based on swept-source tomography (OCT) was implemented a clinical prototype. Low amplitude deformation produced during OCT imaging with linear actuator-driven lens coupled to force transducers. cross-correlation algorithm applied track frame-by-frame speckle displacement across horizontal meridian scans. Intra-measurement and data series were plotted...
Purpose: To assess the predictive accuracy of simulation-based LASIK outcomes. Methods: Preoperative and 3-month post-LASIK tomographic data from 20 eyes 12 patients who underwent wavefront-optimized for myopia were obtained retrospectively. Patient-specific finite element models created case-specific treatment settings simulated. Simulated keratometry (SimK) values mean tangential curvature central 3 mm (Kmean) anterior surfaces clinical tomographies, computational compared. Correlations...
Purpose: There is strong evidence that abnormalities in corneal biomechanical play a causal role ectasias, such as keratoconus. Additionally, crosslinking (CXL) treatment, which halts progression of keratoconus, directly appeals to biomechanics. However, existing methods assessment have various drawbacks: dependence on IOP, long acquisition times, or limited resolution. Here, we present method may avoid these limitations by using optical coherence tomography (OCT) detect the endogenous...
To assess the techniques and materials used in intravitreal injections.Descriptive study realized at Vision Institute of Federal University São Paulo, Brazil.Different brands needles syringes, as well enucleated porcine eyeballs.The ultra-structures commonly were analysed by scanning electron microscope, they compared using different criteria, such irregularities debris from lubrication process. The scleral incision was also assessed sizes. Accuracies drug administration studied comparing...
PURPOSE: Many systems try to replace Placido disc-based topographers, such as those based in Scheimpflug principles. The purpose of this study is check if they are interchangeable. METHODS: Quantitative analysis evaluated data obtained from EyeSys and Pentacam, i.e. simulated keratometric values, addition flattest steepest values. Sixty-three maps each device (EyeSys scale=0.5 D; Pentacam scale= 0.25 D) were used for the comparison. Qualitative selected 10 15 topographies quantitative...
Purpose: To evaluate depth-resolved changes of corneal biomechanical properties in eyes with ectasia after crosslinking (CXL) using optical coherence elastography. Methods: In a prospective pilot series ectasia, custom high-speed swept source tomography system was used to image the cornea before and 3 months CXL during low-speed applanating deformation while monitoring applanation force. Cross-correlation applied track frame-by-frame two-dimensional speckle displacements, slope force versus...
To analyze planning strategies for eyes that gained 1 or more lines of corrected distance visual acuity (CDVA) after topography-guided custom treatment (TCAT).Refractive Surgery Clinic, Cleveland Ohio, USA.Retrospective case series.Eyes having TCAT by the same surgeon between February 2016 and June 2017 were enrolled. The corneal shape was captured with Wavelight Allegretto Topolyzer diagnostic device coupled refraction, generating an ablation profile. cylinder magnitude axis laser entry...
Purpose To assess the ability of air puff-derived biomechanical variables to predict surgeon-perceived candidacy for laser in situ keratomileusis (LASIK). Setting Cole Eye Institute, Cleveland Clinic, Cleveland, Ohio, and Emory University, Atlanta, Georgia, USA. Design Retrospective case series. Methods Data were collected from refractive surgery screening examinations by 2 surgeons at centers. Disqualified cases (19 eyes 28 each surgeon) judged not be candidates based on available data...
Purpose: Fabry disease is an X-linked lysosomal storage disorder that results in multi-systemic renal, cardiovascular, and neuropathological damage, including the eyes. We evaluated anterior segment ocular abnormalities based on age, sex (male female), genotype (wild-type, knockout [KO] male, heterozygous [HET] female, KO female) a rat model of disease. Methods: The α-Gal A WT rats were divided into young (6–24 weeks), adult (25–60 aged (61+ weeks) groups. Intraocular pressure (IOP) was...
