Purpose: The present study aimed to review the effect of dehydration during Ramadan fasting on the health and ocular parameters leading to changes in eye function. Methods: Articles included in the study were taken from Pub Med, Ovid, Web of Science and Google Scholar up to 2014.Related articles were also obtained from scientific journals in fasting and eye. Results: Dehydration and nutrition c...

PURPOSE To investigate clinical, anatomic and electroretinographic changes in eyes that suffered blunt ocular trauma with commotio retinae. METHODS Patients who presented commotio retinae after unilateral blunt ocular trauma less then 72 hours before were submitted to visual acuity testing, biomicroscopy, binocular indirect ophthalmoscopy, fluorescein angiography, optical coherence tomography...

background: the diagnosis of toxocariasis heavily depends on immunological tests because the number of parasites is usually few in infected tissues, unless they migrate into an organ such as eye. in general, patients with ocular toxocariasis have serum anti- t canis antibody titres that are significantly lower than those with visceral toxocariasis. objective: to diagnose the asymptomatic toxoca...

behçet’s disease (bd) is a multisystem disorder with potential ability to influence the pregnancy outcome and pregnancy is associated with several physiologic alterations which can lead to potential changes in the course of the disease. we studied 77 pregnancies in 69 women with bd. the disease activity was calculated by two methods for three periods of before, during and after pregnancy to eva...

introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients.   materials and methods: patients were referred from the otolaryngology department for vestibular assessment...

Increased vascular calcification and tortuosity are rather common in end-stage renal failure patients who are on hemodialysis. It renders manipulation of catheters and performance of percutaneous transluminal interventions more difficult than expected. Such vascular alterations may be evident in large veins and pose significant difficulties in placement of pacing leads as shown in our case. To ...

The present study aims to verify whether dogs and cats submitted dissociative anesthesia for elective orchiectomy may alterations in the tear production consequent lesions on ocular surface. For this purpose, 40 animals, 22 18 dogs, underwent an ophthalmic semiotechnique composed of evaluation anterior posterior chambers, fundscopy, Schirmer's test (TLS) fluorescein test. Subsequently, they ane...

A human corneal epithelial cell line, 10.014 pRSV-T (HCR-T cells), has been used to develop a three-dimensional in vitro model of the human corneal epithelium (HCE-T model). HCE-T cells form a stratified culture when grown at the air-liquid interface on a collagen membrane in serum-free medium. This model served as the basis for assays which supported the ocular irritancy assessment of water-so...

PURPOSE To investigate cycloplegic refraction and ocular alignment in a population of preterm children at 1 and 6 years old. PATIENTS AND METHODS We included 261 preterm infants with a birth weight ≤1,500 g and a gestational age ≤32 weeks; there were 217 preterm infants (group 1), 28 preterm infants with mild retinopathy of prematurity (ROP) (group 2), and 16 preterm infants affected by sever...
