Ada E Aghaji, Richard Bowman, Vincent C Ofoegbu, Andrew Smith
In a cross-sectional study to determine the magnitude of dual sensory impairment (DSI-combined hearing and vision loss) in children in single-disability special education schools, children in schools for the blind and schools for the deaf in four states in South-East Nigeria were examined by an ophthalmologist and otorhinolaryngologist to determine the level of their disability and to identify other disabilities if any. Participants were all students with childhood blindness or childhood deafness. The magnitude and causes of DSI and the burden of undetected DSI were the main outcome measures...

N Feltgen, A Pielen
Retinal artery occlusion leads to profound visual impairment in the affected eye. It is rarely caused by local ophthalmic pathologies. Most patients present with a large number of cardio- and cerebrovascular risk factors. Visual loss is the leading symptom in central retinal artery occlusion (CRAO), whereas a circumscribed visual field defect is claimed in branch retinal artery occlusion (BRAO). Although many attempts have been made to improve the course of the disease, no effective therapy is available. There is some hope that intravenous fibrinolysis could influence the natural course but the therapeutic window is small (ca...

Siyamalan Manivannan, Caroline Cobb, Stephen Burgess, Emanuele Trucco
We propose a novel multiple instance learning method to assess the visibility (visible/not visible) of the retinal nerve fiber layer (RNFL) in fundus camera images. Using only image-level labels, our approach learns to classify the images as well as to localize the RNFL visible regions. We transform the original feature space to a discriminative subspace, and learn a region-level classifier in that subspace. We propose a margin-based loss function to jointly learn this subspace and the region-level classifier...

Ocular topically applied Vancomycin (VCM) suffers poor bioavailability due to its high molecular weight and hydrophilicity. In the present investigation, VCM-loaded polymeric nanoparticles (PNPs) were developed aiming to enhance its ocular bioavailability through prolonging its release pattern and ophthalmic residence. PNPs were prepared utilizing double emulsion (W/O/O), solvent evaporation technique. 2(3)×4(1) full factorial design was applied to evaluate individual and combined influences of polymer type, Eudragit® RS100, sonication time, and Span®80 concentration on PNPs particle size, encapsulation efficiency, and zeta potential...

BACKGROUND: Uveitis and optic neuritis are prevalent ocular inflammatory diseases, and highly damaging ocular conditions. Both diseases are currently treated with corticosteroids, but they do not have adequate efficacy and are often associated with severe side effects. Thus, uveitis and optic neuritis remain a challenging field to ophthalmologists and a significant public health concern. OBJECTIVE: This review summarizes findings showing the benefits of a treatment with melatonin in experimental models of these inflammatory ocular diseases...

The diagnosis of Graves' orbitopathy is usually straightforward. However, orbital diseases that mimick some clinical signs of Graves' orbitopathy may cause diagnostic confusion, particularly when associated to some form of thyroid dysfunction. This report describes the rare occurrence of localized inferior rectus muscle amyloidosis in a patient with autoimmune hypothyroidism, who was misdiagnosed as Graves' orbitopathy. A 48-year-old man complained of painless progressive proptosis on the left side and intermittent vertical diplopia for 6 months...

OBJECTIVES: Hormonal changes during oral contraceptive pill (OCP) use may affect central corneal thickness (CCT) values. We aimed to evaluate the impact of OCP use on CCT values in healthy young women. MATERIALS AND METHODS: Fifty women subjects who use OCP for contraception (Group 1) and forty control subjects (Group 2) who do not use OCP were included in this prospective study. None of the patients had any history of systemic or ocular diseases. The CCT values measured by ultrasonic pachymeter (Nidek US-4000 Echoscan, Japan) and the intraocular pressure (IOP) values were measured by noncontact tonometer (Reichert 7 CR Corneal Response Technology, USA) at the time of admission to our clinic...

INTRODUCTION: Diagnosis of axial spondyloarthritis (SpA) can be delayed for several years mainly because of low awareness of axial SpA among non-rheumatologists who are the first interlocutors of potential SpA patients. One strategy to decrease the delay between appearance of first symptoms and diagnosis of axial SpA and to allow early management of the disease is to provide the non-rheumatologists with tools to identify patients requiring prompt referral to rheumatologists. This study was designed to evaluate in a real-world setting whether screening patients with chronic low back pain who consult physical medicine and rehabilitation (PMR) physicians, orthopedists, and ophthalmologists is useful in detecting axial SpA...

BACKGROUND: Traditional orthoptic therapy used by ophthalmologists, orthoptists, and optometrists is directed at improving visual acuity, ocular alignment, or both. For example, convergence exercises are used to treat convergence insufficiency (CI). However, other forms of "vision therapy" are directed at improving "visual processing and efficiency." The therapeutic regimen often entails repetitive ocular motor tasks performed during multiple office visits with a behavioral optometrist...
