Optic Nerve Head Drusen, Myopia and Ocular Hypertension: A Case Report  [PDF]
Arzu Taskiran Comez, Baris Komur
Open Journal of Ophthalmology (OJOph) , 2014, DOI: 10.4236/ojoph.2014.41001

A 20-year-old male patient presented at our clinic complaining of strange visual experiences (neither decreased nor blurred) and a mild headache while reading. His best corrected visual acuity revealed 20/20 with a fort myopic correction. Intraocular pressures measured with Dynamic Contour Tonometer (DCT) (Swiss Microtechnology AG, Port, Switzerland) were 23.3 mmHg in the right eye (OD) and 27.4 mmHg in the left eye (OS) with cenral corneal thicknesses (CCTs) of 588 (OD) and 591 (OS) microns, respectively. Optic discs were bilateral pale with indistinct and scalloped margins without cupping. Red free photos showed autofluorescence of both optic discs, representative of optic disc drusen. Visual field analysis (VFA) of both eyes revealed sensitivity depression with localized defects consistent with the Optical Coherence Tomography (OCT) findings. Optic nerve head drusen (ONHD), myopia and high intraocular pressures (IOPs), may cause ganglion cell damage resulting in RNFL thinning and visual field loss. Because of the difficulty in detecting the exact cause and the extent of the damage, patients with ONHD associated with high IOPs and myopia should be examined closely with serial monitoring using OCT and VFA. In case of RNFL thinning and visual field

Abstract: otulinum toxin injections for blepharospasm prior to ocular surgeries Original Research (2387) Total Article Views Authors: Okumus S, Coskun E, Erbagci , Tatar MG, Comez A, Kaydu E, Yayuspayi R, Gurler B Published Date May 2012 Volume 2012:6 Pages 579 - 583 DOI: http://dx.doi.org/10.2147/OPTH.S30277 Received: 27 January 2012 Accepted: 12 March 2012 Published: 03 May 2012 Seydi Okumus1, Erol Coskun1, brahim Erbagci1, M Gürkan Tatar2, Aysegul Comez1, Erdal Kaydu1, Ramazan Yayuspayi1, Bulent Gurler1 1Department of Ophthalmology, University of Gaziantep, 2Ophthalmology Clinic, Nizip State Hospital, Nizip, Gaziantep, Turkey Purpose: The aim of this study was to show the efficiency of preoperative botulinum toxin A (Botox A) in patients with benign essential blepharospasm who were to undergo ocular surgery with local anesthesia. Materials and methods: Twenty-eight benign essential blepharospasm patients who were administered unilateral Botox A prior to ocular surgery between January 2004 and May 2011 were included in this study. Eleven cases had pterygiums, ten had cataracts, and four had glaucomas, while the remaining three had aphakia. All cases’ severity of spasm (stage 0–4) and eyelid closing forces (stage 1–4) were evaluated according to the Jankovic scale prior to the injection, at 3 days, 14 days, 1 month, and 3 months after Botox A injection. Results: Of the patients enrolled in the study, 16 were female and 12 were male, with an average age of 55.52 ± 1.53 years (52–65). Average onset of the Botox injection's effect was 2.8 ± 0.9 (2–5) days. Its effect lingered for about 11.5 ± 3.6 (8–22) weeks. The severity of spasm and eyelid closing forces of all the patients enrolled were compared prior to the injection at 3 and 14 days and the first and third months after the injection. There were statistically significant differences between prior to the injection and 3 days (P = 0.001), 14 days (P < 0.001) and 1 month after the injection (P <0.001). There was no statistically significant difference between prior to the injection and 3 months after the injection (P = 0.513). Fourteen days following the injection, the surgeries were successfully performed. Conclusion: Botox A administered prior to ocular surgery will control both blepharospasm and lower the risks that can be encountered before and during surgery, thus increasing the comfort of the patient and the surgeon.
Slow dynamics of salol: a pressure and temperature dependent light scattering study
L. Comez,S. Corezzi,D. Fioretto,H. Kriegs,A. Best,W. Steffen
Physics , 2014, DOI: 10.1103/PhysRevE.70.011504
Abstract: We study the slow dynamics of salol by varying both temperature and pressure using photon correlation spectroscopy and pressure-volume-temperature measurements, and compare the behavior of the structural relaxation time with equations derived within the Adam-Gibbs entropy theory and the Cohen-Grest free volume theory. We ?nd that pressure dependent data are crucial to assess the validity of these model equations. Our analysis supports the entropy-based equation, and estimates the con?gurational entropy of salol at ambient pressure ? 70% of the excess entropy. Finally, we investigate the evolution of the shape of the structural relaxation process, and ?nd that a time-temperature-pressure superposition principle holds over the range investigated.
Hard sphere-like dynamics in a non hard sphere liquid
T. Scopigno,R. Di Leonardo,L. Comez,A. Q. R. Baron,D. Fioretto,G. Ruocco
Physics , 2005, DOI: 10.1103/PhysRevLett.94.155301
Abstract: The collective dynamics of liquid Gallium close to the melting point has been studied using Inelastic X-ray Scattering to probe lengthscales smaller than the size of the first coordination shell. %(momentum transfers, $Q$, $>$15 nm$^{-1}$). Although the structural properties of this partially covalent liquid strongly deviate from a simple hard-sphere model, the dynamics, as reflected in the quasi-elastic scattering, are beautifully described within the framework of the extended heat mode approximation of Enskog's kinetic theory, analytically derived for a hard spheres system. The present work demonstrates the applicability of Enskog's theory to non hard- sphere and non simple liquids.

Optimal quantizers for probability distributions on Sierpiński carpets
Dogan Comez,Mrinal Kanti Roychowdhury
Mathematics , 2015,
Abstract: In this paper, we investigate the optimal sets of $n$-means and the $n$th quantization error for singular continuous probability measures on $\mathbb R^2$ supported by Sierpi\'nski carpets. Utilizing the geometric structure of Sierpi\'nski carpets, first we determine the optimal sets of $n$-means for Borel probability measures $P$ on $\mathbb R^2$ supported by Sierpi\'nski carpets in progressive steps. Then, using suitable Voronoi partitions associated, we obtain the number of optimal sets of $n$-means as well as the $n$th quantization error involved in each case.
Can experiments select the configurational component of excess entropy?
Silvia Corezzi,Lucia Comez,Daniele Fioretto
Physics , 2002,
Abstract: We introduce an experimental method of assessing the vibrational and configurational components of the excess entropy of a liquid over crystal, based on a joined investigation of dynamic and thermodynamic properties as a function of temperature and pressure. We analyze light scattering, dielectric, calorimetric and dilatometric measurements of three prototype glass formers, orthoterphenyl, salol, and glycerol. In all cases we find that about 70% of the excess entropy is configurational in nature.
On pointwise ergodic theorems for infinite measure
Vladimir Chilin,Dogan Comez,Semyon Litvinov
Mathematics , 2015,
Abstract: For a Dunford-Schwartz operator in the $L^p-$space, $1\leq p< \infty$ , of an arbitrary measure space, we prove pointwise convergence of the conventional and Besicovitch weighted ergodic averages. Pointwise convergence of various types of ergodic averages in fully symmetric spaces of measurable functions with non-trivial Boyd indices is studied. In particular, it is shown that for such spaces Bourgain's Return Times theorem is valid.
A Minor Modification of Direct Browplasty Technique in a Patient with Brow Ptosis Secondary to Facial Paralysis: Copy-Paste-Excise and Stitch

Case Reports in Ophthalmological Medicine , 2013, DOI: 10.1155/2013/952079
Abstract: Purpose. This report aimed to describe a minor modification of the traditional direct browplasty technique that aids in surgical planning for patients with brow ptosis secondary to facial paralysis without changing the shape of the brow. Case Report. A 74-year-old male patient with left facial paralysis secondary to chronic otitis media was referred with a complaint of low vision due to brow ptosis. We performed direct browplasty with a minor modification in order to aid a treatment customized to the patient. In this technique, a transparent film paper is used to copy the brow shape. A brow-shaped excision is facilitated just superior to the ptotic brow. Conclusion. The authors found that the copy-paste-excise and stitch technique was effective and successful for deciding the shape and the amount of excision that should be performed in patients with brow ptosis without resulting in asymmetrical, arched, and feminized brows. 1. Introduction The brow consists of skin, subcutaneous tissue, muscle, and cilia and has a characteristic shape that is gender dependent [1]. In both men and women, the brow begins at the superomedial orbital rim and runs vertically through the medial canthus and nasal ala [2–4]. Although the beginning portion is similar, there are distinct differences between the two sexes. The normal position of the brow is just above the superior orbital rim in females and at the superior orbital rim in males. The female brow is more arched with a less prominent fat pad than males. In females, the brow arches above the supraorbital rim, whereas in men it arches only minimally along the rim [5]. The direct browplasty is suitable for any degree of brow ptosis secondary to injury of the temporal branch of the seventh cranial nerve in males as well as for older females with thick brows. It is an easy technique to perform, provides good control over the amount of brow lift, and gives predictable results [6]. The direct browplasty involves bilateral elliptical incisions immediately above the brows [7]. Closure of the elliptical excision area alters the brow’s shape resulting in an arched brow with the maximum arch being at the center of the brow and feminized appearance [6–8]. Besides, arching may lead to a surprised look or “clown” appearance. With this report we aimed to prevent this over-lifted appearance and achieve symmetrically localized brows with a minor modification in traditional direct browplasty procedure in patients with brow ptosis. 2.
