PIDR(s): IDR(s) as a Projection Method
No full textThe Induced Dimension Reduction(s) method (or the IDR(s) method) is an example of an iterative method used for solving systems of linear equations. Projection methods are a special type of iterative method. They find an approximate solution in a subspace (the right subspace) by requiring that the residual is orthogonal to another subspace (the left subspace). In this thesis we investigate how we can implement IDR(s) as a projection method. We call this method IDR(s), which stands for Projected IDR(s).We present an implementation of PIDR(s) for solving systems of linear equations and for solving eigenvalue problems. These implementations are not meant to be optimal, but they are used to show that IDR(s) can indeed be seen as a projection method.Track: educationScience Education and CommunicationApplied Science

Intravitreal bevacizumab for juxtafoveal choroidal neovascularization secondary to multifocal choroiditis
No full textPURPOSE: To assess the effects of intravitreal bevacizumab injections in the treatment of juxtafoveal choroidal neovascularization associated with multifocal choroiditis. METHODS: Prospective interventional case series. Fourteen patients (14 eyes) affected by juxtafoveal choroidal neovascularization secondary to multifocal choroiditis were examined. All patients underwent a complete ophthalmologic examination, including measurement of best-corrected visual acuity using Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography, and fluorescein angiography. The protocol treatment included a first injection, followed by repeated intravitreal bevacizumab injections over a 12-month follow-up period on the basis of optical coherence tomography parameters and angiographic features. RESULTS: Mean best-corrected visual acuity changed from 0.41 logarithm of the minimum angle of resolution (approximately corresponding to 20-51 Snellen equivalent), at baseline, to 0.16 ± 0.13 logarithm of the minimum angle of resolution (approximately corresponding to 20-28 Snellen equivalent), at the 12-month examination (P 0.002). A functional improvement of at least 3 Early Treatment Diabetic Retinopathy Study lines was achieved by 6 eyes (43percent) at the 12-month examination. Mean central macular thickness at baseline was 318 μm, reducing to 239 μm at the 12-month examination (P 0.001). No eye showed choroidal neovascularization extension to the fovea. CONCLUSION: Intravitreal bevacizumab is a beneficial treatment for juxtafoveal choroidal neovascularization associated with multifocal choroiditis. Further studies are warranted to confirm these preliminary results.

Intravitreal bevacizumab for choroidal neovascularisation in serpiginous choroiditis
No full textPurpose To assess the effects of intravitreal bevacizumab (IVB) in the treatment of choroidal neovascularisation (CNV) secondary to serpiginous choroiditis (SC). Design Non-randomised, interventional case series. Participants Seven patients (seven eyes) affected by juxtafoveal CNV (six eyes) and subfoveal CNV (one eye) associated with SC were recruited. Methods Each patient underwent an ophthalmological examination, including measurement of best-correced visual acuity (BCVA), fluorescein angiography (FA) and optical coherence tomography (OCT). After a first IVB injection (1.25 mg), patients were evaluated monthly over a 12-month follow-up. Further re-treatments were performed on the basis of detection of any type of fluid on OCT and-or presence of leakage on FA. The primary outcome considered was the median change in BCVA, as well as the proportion of eyes gaining at least 5 and 10 Early Treatment Diabetic Retinopathy Study (ETDRS) letters at the end of the 12-month follow-up. Secondary outcomes included median changes in central macular thickness (CMT) and number of injections over the planned follow-up. Results Median BCVA changed from 0.3 to 0.4 LogMAR. A functional improvement of at least 5 and 10 ETDRS letters was obtained in two eyes (28percent) and one eye (14percent), respectively, at the 12-month examination. Four eyes (57percent) had stable BCVA, whereas one eye (14percent) experienced a two-line decrease. Median CMT at baseline was 261 μm, decreasing to 196 μm at the 12-month examination. The median number of IVB injections was 1 in 12 months. Conclusions IVB can achieve anatomical stabilization of CNV secondary to SC, avoiding a decline in visual acuity, in almost 90percent of cases over a 12-month followup.Akpek EK, 2002, OPHTHALMOLOGY, V109, P1506, DOI 10.1016-S0161-6420(02)01097-7; Baxter SL, 2013, AM J OPHTHALMOL, V156, P468, DOI 10.1016-j.ajo.2013.04.040; CHEVALLEY G, 1992, KLIN MONATSBL AUGENH, V200, P382, DOI 10.1055-s-2008-1045770; Christmas NJ, 2002, RETINA-J RET VIT DIS, V22, P550, DOI 10.1097-00006982-200210000-00004; Dees C, 1998, ARCH OPHTHALMOL-CHIC, V116, P1456; Dhingra N, 2010, INDIAN J OPHTHALMOL, V58, P3, DOI 10.4103-0301-4738.58467; Gass JDM, 1997, STEREOSCOPIC ATLAS M, P158; HAMILTON AM, 1974, BRIT J OPHTHALMOL, V58, P784, DOI 10.1136-bjo.58.9.784; JAMPOL LM, 1979, AM J OPHTHALMOL, V88, P683; Julian K, 2011, ACTA OPHTHALMOL, V89, P179, DOI 10.1111-j.1755-3768.2010.02046.x; Khanamiri NH, 2013, SURV OPHTHALMOL, V58, P203; Kilmartin DJ, 1998, ARCH OPHTHALMOL-CHIC, V116, P249; Kinnunen K, 2012, ANN MED, V44, P1, DOI 10.3109-07853890.2010.532150; Kuo IC, 2000, INT OPHTHALMOL CLIN, V40, P111, DOI 10.1097-00004397-200004000-00009; Lim WK, 2005, SURV OPHTHALMOL, V50, P231, DOI 10.1016-j.survophthal.2005.02.010; Mahendradas P, 2007, OCUL IMMUNOL INFLAMM, V15, P127, DOI 10.1080-09273940701244202; Mansour AM, 2009, AM J OPHTHALMOL, V148, P310, DOI 10.1016-j.ajo.2009.03.023; Mansour AM, 2008, AM J OPHTHALMOL, V146, P410, DOI 10.1016-j.ajo.2008.05.024; Neri Piergiorgio, 2010, International Ophthalmology, V30, P583, DOI 10.1007-s10792-009-9323-x; O'Toole Louise, 2005, International Ophthalmology Clinics, V45, P157, DOI 10.1097-01.iio.0000155902.49562.4a; Oh H, 1999, INVEST OPHTH VIS SCI, V40, P1891; Park SP, 2006, OPHTHAL SURG LAS IM, V37, P425; Parodi MB, 2010, ARCH OPHTHALMOL-CHIC, V128, P1100, DOI 10.1001-archophthalmol.2010.205; Parodi MB, 2010, OCUL IMMUNOL INFLAMM, V18, P399, DOI 10.3109-09273948.2010.483316; Parodi MB, 2013, RETINA-J RET VIT DIS, V33, P953, DOI 10.1097-IAE.0b013e318275397c; Parodi MB, 2010, DEV OPHTHALMOL, V46, P84; Priya K, 2002, OCUL IMMUNOL INFLAMM, V10, P247; Rouvas A, 2011, RETINA-J RET VIT DIS, V31, P871, DOI 10.1097-IAE.0b013e3182003ca8; Shimada H, 2008, JPN J OPHTHALMOL, V52, P282, DOI 10.1007-s10384-008-0566-2; Song MH, 2009, EYE, V23, P1873, DOI 10.1038-eye.2008.346; van Wijngaarden P, 2008, CLIN EXP OPTOM, V91, P427, DOI 10.1111-j.1444-0938.2008.00305.x; Vasconcelos-Santos DV, 2010, ARCH OPHTHALMOL-CHIC, V128, P853, DOI 10.1001-archophthalmol.2010.116; Vinores SA, 1997, HISTOL HISTOPATHOL, V12, P99; WEISS H, 1979, AM J OPHTHALMOL, V87, P1330

Central retinal vein occlusion in a young patient following cannabis smoke inhalation
No full textPurpose: To report a case of central retinal vein occlusion (CRVO) following cannabis smoke inhalation in a young patient. Methods: An otherwise healthy 18-year-old man without risk factors for retinal vein occlusion presented with reduced visual acuity (20/200) secondary to CRVO following cannabis smoke inhalation. Central retinal vein occlusion was diagnosed on the basis of slit-lamp fundus biomicroscopy and fluorescein angiography. Results: Tests for systemic causes were negative. Following one intravitreal dexamethasone implant (Ozurdex) and one ranibizumab injection (Lucentis), functional (20/20 visual acuity) and anatomic improvement was recorded. Fluorescein angiography showed a decrease in the vascular caliber and tortuosity, with no signs of retinal ischemia or edema. Conclusions: We report CRVO in a young adult following cannabis smoke inhalation. Its occurrence immediately after cannabis smoking further supports a link between the use of cannabis and vascular alterations
LA PRIMA RICEZIONE DELLA FENOMENOLOGIA NEGLI STATI UNITI: UN'ANALISI STORICO-CRITICA
No full textMy research analyzes the characteristics of the first reception of husserlian phenomenology in the United States. The base of this work is a detailed historiographical reconstruction of this phase representing the point of departure of all those studies on phenomenological tradition that have been developed in the American academic world. Several institutions belong to the context in which this reception took place: the New School for Social Research as the original center for the teaching of phenomenology and a number of societies arisen since the sixties to diffuse Husserl’s philosophy in the United States (First Part: Chapter 2 and Chapter 3).
This first reception, promoted since the late thirties by Kaufmann, Schutz, Gurwitsch, Cairns and Farber, must be distinguished from an earlier phase, presenting only the general approach to Husserl’s thought of some American scholars (Second Part: Chapter 1). The origin of the studies of each author undoubtedly typifies their promotion of husserlian phenomenology: Gurwitsch, Schutz and Kaufmann belong to the European tradition, (First Part: Chapter 1) while the Americans Farber and Cairns mainly owe the growing interest in Husserl’s thought to their studies in Freiburg (Second Part: Chapter 2). Nevertheless, during this phase of reception of phenomenology, the original adherence to his lesson – useful to distinguish them from others Husserl’s students emigrated in United States – gradually disappears from their critiques. The aim of my research is to single out the salient features that characterize the different interpretations of Husserl’s thought elaborated by each author, whereas their originality can be indicated as decisive for following developments (Third Part). Gurwitsch builds an interesting critique of Husserl’s whole-part theory, focuses his analysis on the noema, and elaborates a non-egological conception of consciousness. Schutz’s critique of transcendental phenomenology mainly refers to his concept of mundane intersubjectivity. For what concerns Cairns, his few writings published until now don’t allow to deepen the exam on his interpretation. After the arrival in the United States, Kaufmann concentrates his discussion on the relationship between husserlian phenomenology and the logic. Farber proposes a critique which is far from being an original interpretation, although his analysis remains bound to the interest in phenomenology until the end.
With this work I want to explain how the interest about husserlian phenomenology began in the United States, who were its promoters, and also what kind of interpretations they developed in the American academic world. It must be considered that they hadn’t a decisive influence on further developments of phenomenological studies, but in any case helped bringing the attention on Husserl’s thought throughout their teaching
