Laser Speckle Flowgraphy in Caucasians: Age Dependence and Comparison With Doppler Optical Coherence Tomography

Some of the most prevalent eye diseases such as age-related macular degeneration, glaucoma and diabetic retinopathy are associated with ocular perfusion abnormalities. Currently, there is no gold-standard method for the measurement of ocular blood flow available. Laser speckle flowgraphy is a promising technique for the two-dimensional assessment of ocular blood flow in humans. So far the technique has, however, been only gained widespread use in Japan. The experience in Caucas...

Using the Speckle Doppler to Quantify Blood Flow in Kidney and Pancreas Grafts

Kidney and Pancreas transplantation is considered the treatment of choice for many people with End Stage Renal Disease and Type 1 diabetes because quality of life and survival is often better after transplantation. However the quality of organs varies as does the quality of perfusion once they are transplanted. The immediate determinant of the survival of any transplanted allograft often depends on the overall quality of perfusion of the organ. The assessment of perfusion is cu...

Study of the Retinal Vascularization by Laser Doppler Velocimetry Coupled With an Adaptive Optics Camera ( AO-LDV)

The difficulty to measure blood flow in humans is connected with the necessity of using not invasive, reliable and reproducible techniques. There is several quantitative approaches to study eye blood flow which do not answer all these specifications. The laser doppler velocimetry allows movement speed measures but not vessel diameter. Optical coherence tomography doppler allows a simultaneous diameter and speed of travel (movement) measures, but presents a limited spatial reso...

The Validity of Retinal Blood Flow Measurements During Hyperoxia in Humans Using Fourier Domain Color Doppler Optical Coherence Tomography (CDOCT)

Noninvasive monitoring of blood flow in retinal circulation may elucidate the progression and treatment of ocular disorders, including diabetic retinopathy, age-related macular degeneration and glaucoma. Laser Doppler velocimetry (LDV), a noninvasive optical method combined with vessel size determination has been used extensively as a valuable research tool to examine blood flow dynamics in the human retina. However, no information on the velocity profile within the vess...


Subepithelial connective tissue graft (SCTG) is considered the gold standard treatment for root coverage in Miller Class I and II single gingival recession. Therefore, scientific evidence is limited for multiple gingival recessions, only with extrapolation from single-tooth data. Depending on area and depth during the removal of the graft from palate, connective tissue presents different anatomic characteristics, geometric shapes and histological composition. Possibly different...

Circadian Variations in Ocular Blood Flow in Glaucomatous and Normal Eyes

After focusing many years only on intraocular pressure (IOP) as the primary risk factor, recently the impact of ocular blood flow is getting more consideration for the pathophysiology of glaucoma. The circadian change of intraocular pressure (IOP) is well investigated, but diurnal variations in ocular blood flow are yet to be evaluated, especially in glaucomatous eyes. This study is performed to investigate circadian variation of ocular blood flow assessed by laser inter...

Measurement of Total Retinal Blood Flow During Flicker Stimulation in Healthy Subjects

Neurovascular coupling or functional hyperemia is defined as an essential physiologic mechanism in the brain, which is necessary for the local adaption of blood flow to altered metabolic demands of the tissue. It has been shown that also in the eye, blood flow is considerably coupled to retinal neural activity. The current concept of functional hyperemia is that visual stimulation, as flicker light, effectuates increasing neural activity in the retina, which elevates the metabo...

Effect of Low-Level Laser on Pain and Healing of Donor Site Following Free Gingival Graft

The aim of this randomized split-mouth design clinical trial is to clinically evaluate the effectiveness of diode laser in the healing of donor site of palate in free gingival graft.

The purpose of this study is to investigate the thyroid vascularity and blood flow by Color Flow Doppler Sonography in patients with subclinical thyroid dysfunction

Assessment of Lateral and Vertical Tissue Displacement Obtained by the Retraction Cord and Diode Laser

In fixed prosthodontic treatment, deflection of gingival tissues for diagnosis or making an impression is one of the important phases. Gingival displacement is defined as "displacement of gingival tissues both in vertical and lateral dimensions". Lateral retraction displaces the tissues so that an adequate bulk of impression material can be interfaced with the prepared tooth. Vertical retraction exposes the uncut portion of the tooth apical to the finish line Conventional gingi...

Doppler Flow Wires in Cerebral Angiography

The purpose of this study is to use a wire with a Doppler tip to measure blood flow in vessels in the brain and determine hemodynamic factors associated with treatment success or failure. Many neurological diseases cause abnormal blood flow in the brain in specific vessels. The special wire used in this study is place into brain blood vessels during standard of care procedure to treat such diseases, and blood flow parameters (such as velocity and pressure) are measured to gain ...

Cutaneous Microcirculation and Nervous Sensitivity in Psoriasis

Psoriasis is a chronic inflammatory cutaneous disease, affecting 3% of the French population. Among psoriatic patients, 80% feel pain or cutaneous discomfort related to their pathology. Neurogenic inflammation's role in psoriasis has recently been put forward by a study showing that TRPV1 ion channels are necessary to establish psoriasiform inflammation in mice. The investigators hypothesize that there is a link between cutaneous sensory neuropathies and altered cutaneo...
