Wireless Microrobotic Oxygen Sensing for Retinal Hypoxia Monitoring
نویسندگان
چکیده
This paper presents a luminescence oxygen sensor for retinalhypoxia monitoring. The sensor coats a wirelessly controlled magnetic microrobot that will operate in the human eye. The coating embodies Pt(II) octaethylporphine (PtOEP) dyes as the luminescence material and polystyrene as a supporting matrix. It is deposited on the microrobot as a thin film and this film is experimentally evaluated using a custom optical setup. Due to the intrinsic nature of luminescence lifetimes, oxygen concentration was determined using a frequency-domain lifetime measurement approach.

Oxygen sensing in retinal health and disease.
The retina has a uniquely high metabolic demand for oxygen that is normally met by a highly efficient vascular supply. Oxygen plays an essential role in oxidative phosphorylation as an electron acceptor in the mitochondrial respiratory chain in the synthesis of adenosine triphosphate required to support the metabolic demand, including that of the visual cycle. Maintenance of normal retinal func...
متن کاملIn Vivo Imaging of Retinal Hypoxia in a Model of Oxygen-Induced Retinopathy
Ischemia-induced hypoxia elicits retinal neovascularization and is a major component of several blinding retinopathies such as retinopathy of prematurity (ROP), diabetic retinopathy (DR) and retinal vein occlusion (RVO). Currently, noninvasive imaging techniques capable of detecting and monitoring retinal hypoxia in living systems do not exist. Such techniques would greatly clarify the role of ...

Retinal tissue hypoperfusion and hypoxia have been implicated in the pathogenesis of vision-threatening disorders such as diabetic retinopathy, [1-4] age-related macular degeneration (AMD), [5,6] glaucoma, [7,8] and vaso-occlusive retinal disease [9-11]. The ability to detect subtle changes in retinal oxygenation and function might be important for early detection, management, and monitoring of...
متن کاملReduced incidence of atrial fibrillation after cardiac surgery by continuous wireless monitoring of oxygen saturation on the normal ward and resultant oxygen therapy for hypoxia.
OBJECTIVE Monitoring of cardiac surgical patients after transfer from the intensive care unit to the normal ward is incomplete. Undetected hypoxia, however, is known to be a risk factor for occurrence of atrial fibrillation. We have utilized Auricall for continuous wireless monitoring of oxygen saturation and heart rate until discharge. The object of the study was to analyze if oxygen therapy a...
