This paper presents an embedded chip integration technology that incorporates silicon housings and flexible Parylene-based microelectromechanical systems (MEMS) devices. Accelerated-lifetime soak testing is performed in saline at elevated temperatures to study the packaging performance of Parylene C thin films. Experimental results show that the silicon(More)

This paper presents the first implantable, unpowered, parylene-based microelectromechanical system (MEMS) pressure sensor for intraocular pressure (IOP) sensing. From in situ mechanical deformation of the compliant spiral-tube structures, this sensor registers pressure variations without electrical or powered signal transduction of any kind. Micromachined(More)
BACKGROUND Ocular syphilis is reemerging as an important cause of uveitis in the new era of common co-infection with HIV. This study will reveal the clinical and laboratory characteristics in the group of individuals co-infected with ocular syphilis and HIV compared with HIV-negative individuals. In this retrospective observational case series, medical(More)
The first flexible parylene-based multielectrode arrays (MEAs) designed for functional electrical stimulation (FES) in retinal prostheses, and the extension of this technology toward enabling reflex-arc neuromodulation in cases of spinal cord damage or transection, are presented. A single metal layer 16 ×16 retinal electrode array of 125 μm-diameter(More)

PurposeCorrelate OCT-derived measures of drusen and retinal pigment epithelium (RPE) atrophy areas (RAs) with demographic features in an elderly population.Patients and methodsSubjects aged 50 years and older underwent Cirrus OCT scanning. Drusen area and volume were obtained from the macula within a central circle (CC) of 3 mm and a surrounding perifoveal(More)
PURPOSE To evaluate visual and anatomical outcomes of diabetic tractional retinal detachment repaired with pars plana vitrectomy. METHODS Operative records were used to retrospectively identify all patients with tractional retinal detachments secondary to proliferative diabetic retinopathy surgically repaired with pars plana vitrectomy between November 1,(More)
