Understanding the mathematical relationships of volume blood flow and wall shear stress with respect to microvessel diameter is necessary for study vascular design. Here, first time, were quantified from axial red cell velocity measurements in 104 conjunctival microvessels 17 normal human volunteers. Measurements taken a slit lamp based imaging system post capillary side bulbar conjunctiva diameters ranging 4 24 micrometers. The variation profile was into account by using factor function....
Vitamin D has been shown to have anti-angiogenic properties and play a protective role in several types of cancer, including breast, prostate cutaneous melanoma. Similarly, vitamin levels be for risk number conditions, cardiovascular disease chronic kidney disease, as well numerous autoimmune disorders such multiple sclerosis, inflammatory bowel diseases type 1 diabetes mellitus. A study performed by Parekh et al. was the first suggest age-related macular degeneration (AMD) showed...
To evaluate the reliability and construct validity of a Greek version NEI-VFQ-25 in patients with chronic ophthalmic diseases.We developed instrument using forward backward translation. One hundred-eighty-six responded to questionnaire. examine reliability, Cronbach's alpha for each subscale was used as an index internal consistency. Test-retest evaluated intraclass correlation coefficients. Regarding validity, both convergent discriminant validities were calculated by means multi-trait...
Purpose The aim of the study was to assess vision-specific quality-of-life (VS-QoL) Greek glaucoma patients, and impact potential influencing factors. Methods This a 2-center, cross-sectional study. One hundred twenty-one patients were recruited from outpatient service 100 successfully responded self-administered, version National Eye Institute Visual Function Questionnaire 25. results quantified in terms scores (0-100) correlations with possible modifiers investigated. effects sex, income,...
Background. The aim of this study is to present a method lid laxity evaluation and investigate whether there an association between floppy eyelid syndrome (FES) body mass index (BMI) in sleep apnea (SAS) patients compared normal subjects. Method. A total 135 participants (81 with SAS 54 subjects) had full ophthalmologic examination. presence FES was estimated relation BMI. Results. characterized "hyperelastic," "FES stage 1 (asymptomatic)," or 2 (symptomatic)" depending on its capacity....
Vehicle-to-everything (V2X) communications is an emerging branch of wireless and has recently gained a lot interest not only from academia but also the automotive telecommunications industry. An important feature V2X telecommunication systems that communication quality varies quickly in time due to high mobility transceivers rapid change fading characteristics medium. For this reason, it vital maintain tolerable service (QoS) environment, terms reliability, power, end-to-end latency, data...
Abstract Introduction Antiphospholipid syndrome is an autoimmune disorder characterized by either a history of vascular thrombosis (one or more clinical episodes arterial, venous, small vessel in any tissue organ) pregnancy morbidity association with the presence antiphospholipid antibodies. The systemic features are large variability depending on affected organ(s). Among them, neurological and behavioural disturbances, dermatological as livedo reticularis renal, ocular, liver valvular heart...
To investigate the hemostatic effects of SF6 gas in preventing postoperative vitreous hemorrhage diabetic vitrectomy.A prospective, randomized study 33 eyes with hemorrhage, treated by vitrectomy. In 17 our cases 20% was injected into eye at end operation, while 16 BSS remained cavity.The incidence recurrence 17.6% for group and 12.5% (statistically not significant). Progression lens opacities observed 23.5% group, 18.8% significant, a higher group).SF6 did show studied. Furthermore, it may...
We report an adolescent boy with minimal pre-existing risk for thromboses who suffered central retinal vein occlusion associated isotretinoin use acne. To the best of our knowledge, this is first well documented case association.An otherwise healthy 17-year-old white man was treated systemic recalcitrant acne referred in one eye. Although a detailed investigation negative, DNA testing revealed that patient heterozygous carrier G20210A mutation prothrombin gene. Despite fact particular...
A 57-year-old woman was treated by photodynamic therapy for macular edema due to idiopathic juxtafoveal telangiectasis (presumed type 1A) without subretinal neovascularization. Initial visual acuity of the eye 20/200 and it improved 20/40 3 months after session. Visual remained stable 32 treatment. Color photographs fundus fluorescein angiography before revealed regression hemorrhages, exudates, leakage. Photodynamic has long-term benefits patient with telangiectasis, presumed 1A, because...
Channel coding is a fundamental procedure in wireless telecommunication systems and has strong impact on the data transmission quality. This effect becomes more important when must be characterised by low latency bit error rate, as case of vehicle-to-everything (V2X) services. Thus, V2X services use powerful efficient schemes. In this paper, we thoroughly examine performance most channel schemes More specifically, 4th-Generation Long-Term Evolution (4G-LTE) turbo codes, 5th-Generation New...
OBJECTIVE—To study the influence of glycemic control and presence microalbuminuria on initial response to panretinal photocoagulation (PRP) in patients with a high-risk proliferative diabetic retinopathy (PDR). RESEARCH DESIGN AND METHODS—This was prospective cohort two-by-two factorial design. We used full-scattered PRP treat 115 eyes type 2 who have PDR. HbA1c (A1C) albumin levels 24-h urine were constantly monitored during preenrollment, treatment, posttreatment periods. At follow-up...
Backround: Genetic variants are implicated in the development of diabetic retinopathy (DR) and nephropathy (DN). The role solute carrier family 2-facilitated glucose transporter member 1 (SLC2A1), also known as (GLUT1), on DR DN remain controversial.Examination influence tag SLC2A1 single-nucleotide polymorphisms (SNPs) during course type 2 diabetes mellitus (T2DM).A total 169 patients with or DN, 107 uncomplicated T2DM patients, 315 controls were recruited genotyped for 14 SNPs. SNPs...
The purpose of this study was to investigate plasma homocysteine levels and polymorphisms in genes encoding enzymes the metabolic pathway association with primary open-angle glaucoma (POAG) pseudoexfoliation (PXFG).A total 156 patients (76 POAG 80 PXFG) 135 controls matched for age sex were enrolled study. Plasma measured using a commercially available enzyme-linked immunosorbent assay kit. DNA extracted from peripheral blood leukocytes real-time polymerase chain reaction performed...
Background: There is accumulating evidence for genetic susceptibility to the development of diabetic retinopathy (DR). The role plasminogen activator inhibitor-1 (PAI-1) in DR risk remains controversial.Objective: present study was designed investigate possible influence PAI-1 gene region polymorphisms on and developing early vs late course type 2 diabetes mellitus (T2DM).Methods: A total 138 patients with DR, 107 T2DM without 315 healthy controls were recruited. To cover majority...
Purpose To evaluate agreement in measurements of astigmatic axis power and location between keratometry computer assisted videokeratography (corneal topography) on normal corneas with less than 1.50 D idiopathic astigmatism.
