PURPOSE The aim of this study is to report the short-term efficacy of aflibercept in the treatment of neovascular age-related macular degeneration (AMD) with associated retinal pigment epithelial detachment (PED) which is refractory or develops tachyphylaxis to bevacizumab and ranibizumab. METHODS The method comprised a retrospective review of the medical(More)
BACKGROUND Longevinex® (L/RV) is a low dose hormetic over-the-counter (OTC) oral resveratrol (RV) based matrix of red wine solids, vitamin D3 and inositol hexaphosphate (IP6) with established bioavailability, safety, and short-term efficacy against the earliest signs of human atherosclerosis, murine cardiac reperfusion injury, clinical retinal(More)
Four different antibiotics, delivered individually to rabbit eyes via hydrophilic intraocular lenses soaked in the drug solution prior to implantation, were measured in aqueous and vitreous humor samples from the eyes. To meet this analytical need, we developed a sensitive, high performance liquid chromatographic (HPLC) method for measuring the(More)
PURPOSE Rare spontaneous remissions from age-related macular degeneration (AMD) suggest the human retina has large regenerative capacity, even in advanced age. We present examples of robust improvement of retinal structure and function using an OTC oral resveratrol (RV) based nutritional supplement called Longevinex® or L/RV (circa 2004, Resveratrol(More)
Acute hypertension, induced in rats by intravenous injection of angiotensin II, previously has been shown to increase cerebrovascular permeability to macromolecules. The purpose of this study was to examine the effect of acute hypertension on Na+,K(+)-ATPase, the enzyme responsible for controlling ionic permeability of the cerebromicrovascular endothelium.(More)
PURPOSE The purpose of this study was to determine the effect on intraocular pressure (IOP) and visual acuity of treating uveitis-related hypotony in patients with vitrectomy and intravitreal silicone oil injection. METHODS Patients who underwent pars plana vitrectomy and silicone oil injection for uveitis-associated hypotony treatment were identified(More)
To examine the mechanisms involved in cerebrospinal fluid (CSF) K+ homeostasis, lateral ventricle choroid plexuses were isolated from rats fed low, normal or high K+ diets for 2 weeks. Potassium (86Rb) influx and efflux were then examined in vitro. Dietary hypo- and hyperkalemia (2.8 +/- 0.1 and 6.8 +/- 0.3 mM) did not affect the efflux rate constant for(More)
This study examined the potential roles of the plasma membrane Ca2+-ATPase (PMCA) at the blood-CSF and blood-brain barriers in brain Ca2+ homeostasis and blood-brain barrier Na+/K+-ATPase subunits in brain K+ homeostasis. During dietary-induced hypo- and hypercalcemia (0.59+/-0.06 and 1.58+/-0.12 mM [Ca2+]) there was no significant change in choroid plexus(More)
PURPOSE To evaluate the time course of drug concentrations achieved in aqueous (AQ), vitreous (V), and serum (S) compartments after oral administration of linezolid and levofloxacin. DESIGN Randomized, clinical trial. METHODS SETTINGS Clinical practice. PATIENT POPULATION Sixteen patients (16 eyes) undergoing vitrectomy who had not had a prior pars(More)
Nontuberculous mycobacterial (NTM) infections are becoming an increasingly important complication in ophthalmology, particularly among immunocompromised patients. We report a case of NTM in a 66-year-old male immunosuppressed after cardiac transplantation. Chronic granulomatous iridocyclitis progressed to purulent endophthalmitis despite intraocular and(More)
