Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry.
2016
AIMS The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA). METHODS Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ORA. The number of GAT and ORA measurements performed on each eye differed depending on the randomly allocated investigation scheme. Central corneal thickness (CCT), anterior chamber volume (ACV) and anterior chamber depth (ACD) were assessed with Pentacam before and after the repeated GAT/ORA measurements. RESULTS There was no sta…
Zur Wirkung von Muskelrelaxantien auf den intraokularen Druck
1988
Since general anesthesia is being used increasingly in ophthalmic surgery, the effects of anesthetic drugs on intraocular pressure (IOP) have to be considered. Competitive neuromuscular blocking drugs either do not affect IOP or produce a slight decrease. Depolarizing muscle relaxants increase IOP. This effect, which is pronounced with succinylcholine, cannot be reliably prevented by any concomitant medication. The new competitive relaxants atracurium and vecuronium provide stable conditions with respect to IOP and systemic circulation, combined with fast onset and intermediate duration of action.
Tear production and intraocular pressure values in clinically normal eyes of whooper swans (<i>Cygnus cygnus</i>)
2018
The objective of this study was to determine the normal range of tear production and values of intraocular pressure (IOP) in clinically normal eyes of whooper swans (Cygnus cygnus). A total of 86 birds: 81 cygnets (6-10 weeks old) and 5 moulting - adult swans (3-6 years old) were examined in this study. Both eyes of all birds underwent a complete ophthalmic examination, including evaluation of tear production with the phenol red thread test (PRTT) and the assessment of the IOP by rebound tonometry, employing the TonoVet® device. The mean ± standard deviation of PRTT values were as follows: all cygnets (81) 22.59±3.48 mm/15s, male cygnets (45) 22.64±3.54 mm/15s, female cygnets (36) 22.53±3.4…
Nonsurgical Procedures for Keratoconus Management
2017
Objectives. To describe the past 20 years’ correction modalities for keratoconus and their visual outcomes and possible complications.Methods. A review of the published literature related to the visual outcomes and possible complications in the context of keratoconus management using nonsurgical procedures for the last 20 years (glasses and contact lenses) was performed. Original articles that reported the outcome of any correction modalities of keratoconus management were reviewed.Results. The most nonsurgical procedure used on keratoconus management is the contact lens fitting. Soft contact lenses and soft toric contact lenses, rigid gas-permeable contact lenses, piggyback contact lens sy…
Percepción visual y traducción audiovisual: la mirada dirigida
2012
En este trabajo, partimos de la premisa de que las destrezas perceptuales innatas necesarias para entender una obra audiovisual son idénticas a las de la percepción visual natural (Grodal 1999: 76). La percepción es una forma inconsciente y natural de interpretar nuestro entorno gracias a la experiencia previa y al aprendizaje. Sostenemos, en contra de la creencia profundamente arraigada en Occidente de que la imagen es universal y verdadera, que la percepción visual es un proceso cognitivo determinado por la experiencia previa, el ambiente, el contexto, los valores culturales y la motivación. En este trabajo vamos a estudiar la aplicación de las investigaciones cognitivas sobre percepción …
Casting the light on cinema – how luminance and contrast patterns create meaning
2012
The question of meaning creation has always been at the core of cross-disciplinary scholarly research. Considered from the cinematographic perspective, it inevitably evokes correlations with plot and dialogue. However, the conveyance of significance in films does not rely solely on the verbal channel, but also manifests itself in the visual layer, ranging from facial expressions, setting and locations, to directorial editing choices. Elevating the role of the how of film making, this article focuses on the influence of light and contrast patterns on the reading of cinema. In order to highlight their position in film text vocabulary and recognize their relevance in film translations and adap…
Functional Role of α1-Adrenoceptor Subtypes in Murine Ophthalmic Arteries
2011
PURPOSE To identify the α(1)-adrenoceptor (α(1)-AR) subtypes mediating vascular adrenergic responses in murine ophthalmic arteries. METHODS Expression of mRNA was quantified for individual α(1)-AR subtypes in murine ophthalmic arteries using real-time PCR. To assess the functional relevance of α(1)-ARs for mediating vascular responses, ophthalmic arteries from mice deficient in one of the three α(1)-AR subtypes (α(1A)-AR(-/-), α(1B)-AR(-/-), and α(1D)-AR(-/-), respectively) and wild-type controls were isolated, cannulated with micropipettes, and pressurized. Changes in luminal artery diameter in response to the α(1)-AR agonist phenylephrine, the sympathetic transmitter noradrenaline, and to…
Efficacy and safety of combined diclofenac 0.1 % and gentamicin 0.3 eyedrops after phacoemulsification
1997
To study the efficacy of combined diclofenac 0.1% and gentamicin 0.3% (Digen) eyedrops to treat postoperative inflammation and prevent ocular infection in eyes having phacoemulsification.Department of Ophthalmology, University of Milan, San Paolo Hospital, Milan; Eye Clinic, University of Verona; and Department of Ophthalmology, University of Palermo, Italy.This double-masked, randomized, clinical trial comprised 90 patients; 45 received Digen and 45, gentamicin 0.3% eyedrops. The main outcome measure of the study was the reduction in signs and symptoms of inflammation, graded on a four-point scale. Also assessed were the presence of bacteria in the conjunctival swab and the proportion of p…
A New Method for Revision of Encapsulated Blebs after Trabeculectomy: Combination of Standard Bleb Needling with Transconjunctival Scleral Flap Sutur…
2016
Purpose A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, postoperative hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early postoperative hypotony: bleb needling combined with transconjunctival sutures tightening the scleral flap directly. Methods The study included two groups of 23 patients with failing bleb following trabeculectomy: “Group 1” underwent simple needling revision of the filtering bleb and served as a control group, while “Group 2” received needling revision with additional transconjunctival scleral flap …
