Filter by:This single-center, prospective, open-label, quasi-experimental, intra-individual comparative study will include a consecutive cohort of 21 patients with diffuse or limited, minimally active scleroderma with 3 to 30 years of evolution. Patients will have 4 sessions of pulsed dye laser 595 nm spaced 8 weeks apart. The final quadruple evaluation by several evaluators will be 2 months after the last session, on the following criteria: evolution of the number of telangiectasia; subjective improvement score (LINKERT scale); impact on quality of life (SKINDEX score); visual analog pain scale (VAS); adverse events (AEs), including discontinuation of treatment due to post-session purpura (AT-PPS); patient satisfaction (yes or no).
1. Facial telangiectasia is one of the common skin vascular lesions characterized by dilated cutaneous vasculatures in the skin surface or mucous membranes. Lesions are generally sensitive to exposure of cold, heat and sun. Those distinct small dilated blood vessels are cosmetically disfiguring for patients which require an effective solution. The traditional management options for facial telangiectasia include cryotherapy, CO2 laser, topical agent, oral estrogens, electrosurgery, and radioactive treatment. However, inadequate outcomes and severe adversaries are the major concerns to patients and physicians. 2. Pulsed dye laser (PDL) is effective for vasodilatory diseases, especially for the superficial to middle layers of the dermis. The intense pulsed light source is an alternative or supplement to the already existing laser devices that are part of the laser surgeon's repertoire. The broad wavelength spectrum and variable pulse duration allow greater penetration depths to be reached without damaging surrounding tissue and thus enhance the versatility of this system. 3. This study aims to compare the clearance efficacy of facial telangiectasia using PDL (595nm) with IPL configured by various wavelength bands, including M22 vascular filter (530-650nm and 900-1200nm), M22 560 (560-1200nm), M22 590 (590-1200nm) .
Objectives: To examine whether dynamic Optical Coherence Tomography (OCT) could characterize vessel dimensions and blood flow of telangiectasias before and after treatment with Intense Pulsed Light (IPL). Methods: Dynamic-OCT (D-OCT) imaged telangiectasia characterized blood vessel width and depth, blood flow, and attenuation. Measurements were done immediately before and after, 1-3 days after, and 1 month after IPL treatment. Characterization of vessel dimensions at baseline were verified by a blinded observer. At one-month follow-up, clinical improvement was characterized as good, moderate or none and possible adverse effects were described.
The purpose of this randomised and controlled study is to investigate the effects of Kinesio Taping method and compression stockings, combined with exercise therapy, on pain, edema, functional capacity and quality of life in patients with chronic venous disease. Therefore, the study compares effectiveness of these two methods for chronic venous disease.
The goal is to compare a novel yellow laser, based on semiconductor technology, with traditional green laser, in the treatment of cheek telangiectasias. The trial design is randomized split-face double-blinded study with 20-30 volunteers. The improvement will be assessed using a 7-point Telangiectasia Grading Scale.
Up to 30 enrolled subjects will be treated. Enrolled subjects will receive Ultherapy® treatments along each length of the spider vein. Follow-up visits will occur at 30 and 60 days post-treatment. Study images will be obtained pre-treatment, immediately post-treatment, and at each follow-up visit.
This study will evaluate the safety and efficacy of the Excel V 532 nm KTP laser for the treatment of dyschromia of the neck and/or chest (poikiloderma of Civatte).
This study will examine whether the drug ranibizumab is an effective treatment for macular telangiectasia, a condition in which existing blood vessels near the macula (the back part of the eye responsible for sharp central vision) become dilated and twisted, and new abnormal blood vessels may form under the retina. Both the existing dilated vessels, as well the new subretinal vessels can leak fluid and blood, distort the retina, and affect vision. This study will see if ranibizumab can slow or stop the leakage and growth of existing, dilated, macular vessels in cases where new vessel formation under the retina is absent. Patients 18 years of age and older who have macular telangiectasia without new blood vessel formation may be eligible for this study. Visual acuity must be 20/40 or worse. Participants receive at least four injections of ranibizumab into the eye over a 12-week period. After the fourth injection, additional injections may be given every 4 weeks for up to 1 year if the doctor determines that they may be of benefit. In addition to ranibizumab treatment, patients undergo the following procedures: - Medical history and physical examination. - Eye examination, including dilation of the pupils and measurement of the fluid pressure in the eye. - Fluorescein angiogram: A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Photographs of the retina are taken with a special camera that flashes a blue light into the eye. The photos show whether any dye has leaked from the vessels into the retina. - Indocyanine green angiography: This procedure identifies feeder vessels that may be supplying the abnormal blood vessels. The test is similar to fluorescein angiography, but uses a green dye and flashes an invisible light. - Autofluorescence imaging: This test examines how well the retina functions. The back of the eye is photographed with a bright light. - Optical coherence tomography: This test measures retinal thickness. A light shined into the eye produces cross-sectional pictures of the retina. The measurements are repeated during the study to determine if retinal thickening is getting better or worse, or staying the same. - Stereoscopic color fundus photography: The pupils are dilated and special photographs of the inside of the eye are taken to evaluate the retina and measure changes that occur over time. The camera flashes a bright light into the eye for each picture. - Follow-up visits: The doctor evaluates the effects of the study treatment before and after each injection. Patients are contacted by phone 3 days after each injection to check on any treatment side effects. A final follow-up visit is scheduled 8 weeks after the last treatment.

This study will see if ranibizumab can slow or stop the leakage and growth of new vessels forming under the retina. Patients 18 years of age and older who have macular telangiectasia in both eyes and new blood vessel formation under the retina in at least one eye may be eligible for this study. Visual acuity must be 20/40 or worse. Participants receive at least four injections of ranibizumab into the eye over a 12-week period.

This research is being done to look at the effects of an experimental drug, ranibizumab, for the treatment of a condition called "idiopathic parafoveal telangiectasia" or IPT. IPT is caused by swelling in the retina (the light sensitive tissue in the back of the eye) due to leaky blood vessels in this area. Swelling in the retina can lead to blurry vision.
