Congenital retinal macrovessels (CRM) are rarely reported, aberrant, large branches of retinal vessels that can be both arteries and veins; however, they are more commonly veins that cross the horizontal raphe to either supply or drain the macula. In this brief report, the authors discuss optical coherence tomography angiography features of CRM in a 12-year-old male patient presenting with low visual acuity in the right eye since childhood. To the authors' knowledge, this is the first such report published in the literature...

The American College of Phlebology Guidelines Committee performed a systematic review of the literature regarding the clinical impact and treatment of incompetent accessory saphenous veins. Using an accepted process for guideline developments, we developed a consensus opinion that patients with symptomatic incompetence of the accessory great saphenous veins (anterior and posterior accessory saphenous veins) be treated with endovenous thermal ablation (laser or radiofrequency) or ultrasound-guided foam sclerotherapy to eliminate symptomatology (Recommendation Grade 1C)...

Modern management of varicose veins Chronic venous disease is a common medical condition and occurs in about one-third of the adult population. Reflux, and to a much lesser extent obstruction of the superficial and deep venous systems, generates venous hypertension. The goal of the treatment is to reduce venous hypertension in order to prevent complications, progression of venous disease and to improve patients' quality of life. Today we have a wide spectrum of different treatment options at our disposal. Management is based upon accurate clinical diagnosis and duplex imaging...

Abnormal subretinal choroidal neovascularization (CNV) is a major cause of blindness in exudative age-related macular degeneration (AMD). Current anti-angiogenic treatments by VEGF sequestering agents have been successful, but a significant proportion of patients do not respond well to these treatments, and the response of others diminishes over time, suggesting that additional anti-angiogenic agents that function by separate mechanisms may be of use to such patients. We have previously found that a point mutated form of semaphorin-3E resistant to cleavage by furin like pro-protein convertases (UNCL-Sema3E) displays potent anti-angiogenic properties...

In vivo photoacoustic flow cytometry (PAFC) has demonstrated potential for early diagnosis of deadly diseases through detection of rare circulating tumor cells, pathogens, and clots in nearly the entire blood volume. Before clinical application, this promising diagnostic platform requires verification and optimization using adequate preclinical models. We show here that this can be addressed by examination of large mouse blood vessels which are similar in size, depth and flow velocity to human vessels used in PAFC...

Minocycline-induced pigmentation (MIP) is an uncommon but well-described adverse effect of oral minocycline treatment. MIP is clinically and histopathologically distinct from post-sclerotherapy pigmentation. We report a case of a patient presenting with blackened skin overlying veins recently treated with endovenous laser and foam sclerotherapy. The patient was a 44-year-old male with systemic sclerosis who commenced minocycline for the treatment of rosacea 5 months prior. Histological examination of the discolored tissue and underlying vein revealed hemosiderin deposition in the dermis and pigmented macrophages within the sub-endothelial layer of the vein wall with a staining pattern consistent with MIP...

PURPOSE: To develop a methodology for cannulating porcine retinal venules using a robotic assistive arm after inducing a retinal vein occlusion using the photosensitizer rose bengal. METHODOLOGY: Retinal vein occlusions proximal to the first vascular branch point were induced following intravenous injection of rose bengal by exposure to 532nm laser light delivered by slit-lamp or endolaser probe. Retinal veins were cannulated by positioning a glass catheter tip using a robotically controlled micromanipulator above venules with an outer diameter of 80μm or more and performing a preset piercing maneuver, controlled robotically...

We report a case of pulsatile varicose veins successfully managed by endovenous laser treatment (EVLT) of the great saphenous vein (GSV). A 77-year-old woman taking an anticoagulant was transferred to our hospital for pulsatile varicose veins complicated with repeated venous bleeding from an ulcer of her left lower leg. Doppler echocardiography showed severe tricuspid regurgitation, and duplex ultrasonography revealed an arterial-like pulsating flow in the saphenofemoral junction and along the GSV, but an arteriovenous fistula, obstruction of the deep veins, and the distal incompetent perforators were not detected...

The images captured by an airborne range-gated imaging system are degraded by many factors, such as light scattering, noise, defocus of the optical system, atmospheric disturbances, platform vibrations, and so on. The characteristics of low illumination, few details, and high noise make the state-of-the-art restoration method fail. In this paper, we present a restoration method especially for range-gated imaging systems. The degradation process is divided into two parts: the static part and the dynamic part...

A 21-year-old healthy female presented with acute-onset vision loss in the left eye. Multimodal imaging, including fundus photography and fluorescein angiography, was unremarkable. En face optical coherence tomography (OCT) demonstrated paracentral acute middle maculopathy (PAMM) lesions in a perivenular fern-like pattern leading to the diagnosis of central retinal vein occlusion (CRVO). En face OCT can be an important modality to identify the distribution of abnormalities of the middle retina such as PAMM...
