Antibiotic Prophylaxis In Orbital Fractures., Benjamin Reiss, Lamise Rajjoub, Tamer Mansour, Tony Chen, Aisha Mumtaz

Ophthalmology Faculty Publications

Purpose:

To determine whether prophylactic antibiotic use in patients with orbital fracture prevent orbital infection.

Design:

Retrospective cohort study.

Participants:

All patients diagnosed with orbital fracture between January 1, 2008 and March 1, 2014 at The George Washington University Hospital and Clinics.

Main Outcome Measures:

Development of orbital infection.

Results:

One hundred seventy-two patients with orbital fracture met our inclusion and exclusion criteria. No orbital infections were documented. Twenty subjects (12%) received no prophylactic antibiotic, and two (1%) received only one dose of antibiotics pre-operatively for surgery. For primary antibiotic, 136 subjects (79%) received oral antibiotics, and 14 (8%) received …

Selective Fusion Of Structural And Functional Data For Improved Glaucoma Detection, Paul Y. Kim, Khan M. Iftekharuddin, Pinakin G. Davey, Gabor Holló, Martha Tóth, Anita Garas, Edward A. Essock

Electrical & Computer Engineering Faculty Publications

This work proposes novel selective feature fusion of structural and functional data for improved glaucoma detection. The structural data such as retinal nerve fiber layer (RNFL) thickness measurement acquired by scanning laser polarimetry (SLP) is fused with the functional visual field (VF) measurement recorded from the standard automated perimetry (SAP) test. The proposed selective feature fusion exploits correspondence between structural and functional data obtained over multiple sectors. The correlation coefficients for corresponding structural-function sector pairs are used as weights in subsequent feature selection. The sectors are ranked according to the correlation coefficients and the first four highly ranked sectors are …

Amaurosis Fugax Due To Pleomorphic Sarcoma, Sheila Pabon, Katherine Williams, Marena Patronas

Ophthalmology Faculty Publications

Purpose

This report describes a case of amaurosis fugax due to a rare primary cardiac sarcoma.

Observations

A patient who was recently diagnosed with left atrial pleomorphic sarcoma presented with a chief complaint of multiple episodes of intermittent vision loss in the right eye during the course of radiation therapy.

Conclusions and importance

The authors postulate emboli from the left atrial sarcoma entered systemic circulation and subsequently caused brief episodes of transient occlusion to retinal, ophthalmic and/or ciliary arteries leading to momentary retinal hypoxia. We believe this is a novel finding, previously unreported in the literature, of transient embolic occlusion …

Iris Abscess A Rare Presentation Of Intravenous Drug Abuse Associated, Jonathan Pierce, Nisha Warrier, Christina Antonopoulos, Nicole Siegel, Deeba Husain

Ophthalmology Faculty Publications

Purpose: To describe an unusual case of intravenous drug abuse associated endogenous endophthalmitis presenting with an iris abscess.

Observations: A 30-year old female with history of intravenous drug use presented with a two-week history of redness and blurry vision in the right eye. An initial diagnosis of anterior uveitis was made. However, she worsened on topical steroids and mydriatics. She was found to have a hypopyon and an iris abscess. She received broad spectrum antibiotic and antifungal treatment with voriconazole, this lead to significant clinical improvement. She was discharged on oral fluconazole and lost to follow up. The patient was …

Frequency Of Retinopathy Of Prematurity In Premature Neonates With A Birth Weight Below 1500 Grams And A Gestational Age Less Than 32 Weeks: A Study From A Tertiary Care Hospital In A Lower-Middle Income Country, Arjumand Sohaila, Shiyam Sunder Tikmani, Iqtidar Ahmed Khan, Huba Atiq, Ali Syed Muhammad Akhtar, Prem Kumar, Kishwer Kumar

Department of Emergency Medicine

Introduction: Retinopathy of prematurity (ROP) is a treatable cause of blindness in neonates. In Pakistan, ROP is often not recognized early because screening and treatment programs are not yet in place in most neonatal units, even in tertiary care hospitals. It is hoped that this report will help inform medical professionals of the magnitude of the problem and help to design appropriate management strategies.

Objectives: The aim was to determine the frequency of ROP in premature and very low birth weight (BW) neonates (BW(GA)weeks).

Study Design: Cross-sectional study.

Study Setting : Neonatal intensive care unit (NICU) of a tertiary care …

In Adult Patients With Diabetic Macular Edema Are Intravetrial Bevacizumab Injections More Effective Than Laser Therapy At Improving Best-Corrected Visual Acuity?, Heather Bladek

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether or not in adult patients with diabetic macular edema intravetrial bevacizumab injections are more effective than laser therapy at improving best-corrected visual acuity.

STUDY DESIGN: Review of three English language non-blinded randomized control trials from 2010 and 2012.

DATA SOURCES: Non-blinded randomized control trials comparing intravetrial bevacizumab injections to macular laser therapy found using Pubmed and EBSCOhost web databases. All articles were published in peer-reviewed journals.

One Student One Family And The Mozambique Eyecare Project, Stephen Thompson, Aoife Phelan, Tatiana Santana, Elizebete Catarino, Vivien Ocampo, Cesar Faria, James Loughman

Articles

Background - The Mozambique Eyecare Programme is funded by Irish Aid and designed to address the need for optometric education in Lusophone Africa. It is a multi-partner collaboration between Universidade Lúrio, Mozambique, Technological University Dublin, Ireland, University of Ulster, Northern Ireland, and The International Centre for Eyecare Education (ICEE) an international Non Government Organisation. A key output from the programme is the development of an optometry school based at Universidade Lúrio, the first of its kind in Mozambique. The aim is to address unmet eye care needs through human resource development.

All students enrolled at Universidade Lúrio, including the optometry …

The Mozambique Eyecare Project: Implementing A Model That Addresses Uncorrected Refractive Error In Lusophone Africa., Stephen Thompson, Diane Wallace

Conference Papers

BACKGROUND

Optometric education and resources are drastically deficient in most of Africa, more so in Lusophone Africa where the problem is compounded by language barriers which isolate these countries from related developments in Africa and/or the developed world.

AIM

This paper aims to document the current situation with regards to human resource development in eyecare in Mozambique and offer …

Molecular Confirmation Of The Causes Of Inherited Visual Impairment In Northern Pakistan, Mehreen Adhi, Yasmin Rashid, Syed Hussain Jafri, Chris F. Inglehearn, Martin Mc Kibbin

Department of Medicine

Families with inherited visual impairment were identified and examined from January 2000 to December 2005 and given a clinical diagnosis. Known genes and loci were screened for mutations or linkage at Institute of Ophthalmology and Neurosciences, University of Leeds, in order to provide molecular confirmation. Inherited retinal disease was the most common cause of inherited visual impairment in 38 of 57 families (66.6%) with Leber’s congenital amaurosis, rod-cone dystrophy and cone-rod dystrophy being the most common diagnoses in 22, 8 and 3 families respectively. Anterior segment dysgenesis was diagnosed in 8 families (14%). Mutations in known genes or linkage to …
