Purpose: To evaluate the anatomical and functional outcome in eyes with indocyanine green (ICG) assisted idiopathic epiretinal membrane (ERM) peeling by optical coherence tomography (OCT) and multifocal electroretinogram (MFERG). Design: Prospective, interventional, noncomparative case series. Methods: Twenty eyes of 20 patients with idiopathic ERM underwent pars plana vitrectomy and ICG assisted ERM and internal limiting membrane (ILM) removal. Visual acuity (VA), OCT and MFERG measurements were performed preoperatively and postoperatively at 1, 3, 6 and 12 months. Results: Best-corrected VA (BCVA) showed improvement of ?2 Snellen lines in 30% and 70% of our patients at the 1st and 12th postoperative month respectively. Mean VA increased from 20/100 preoperatively to 20/40 at 12 months. VA increased significantly at all postoperative examinations, compared to preoperative VA. Retinal thickness measured by OCT decreased significantly at all postoperative examinations. OCT mean values for foveal thickness dropped from 472.3 μm (±87.49) preoperatively, to 249.2 μm (±51.12) at 12 months. Preoperative MFERG values significantly improved compared only to the postoperative values at 12 months for both area 1 (p=0.0016) and area 2 (p=0.0081). Mean retinal response density increased from 4.37 nV/deg² (± 3.27) in area 1 and 3.61 nV/deg² (± 3.73) in area 2, to 10.08 nV/deg² (± 2.57) and 7.32 nV/deg² (± 2.80) respectively. OCT measurements and MFERG values did not correlate at any time

Video-to-Video for e-Health: Use Case, Concepts and Pilot Plan

Part 5: First Intelligent Innovative Ways for Video-to-Video Communication in Modern Smart Cities Workshop (IIVC 2012)International audienceFuture Internet and smart cities are creating a very promising paradigm for providing advanced services to citizens. The paradigm of e-Health forms a valuable yet demanding use case for design, develop, deploy and provide related services. The aim of LiveCity project is to empower the citizens of a city to interact with each other in a more productive efficient and socially useful way by using high quality video-to-video (v2v); v2v can be used to improve medical services. This paper presents the related concepts, the scenario and the pilot set for the tele-monitoring service realization, deployment and provision

The influence of mild posterior capsular opacification on spectral domain optical coherence tomography retinal nerve fiber layer thickness

Purpose tau o investigate whether Yag laser capsulotomy, in addition to restoring ocular media transparency, may also significantly alter retinal nerve fiber layer (RNFL) thickness analysis and spectral domain optical coherence tomography (SD OCT) indices and quality parameters, such as signal strength (SS), in patients with mild, diffuse posterior capsular opacification (PCO). Methods Prospective interventional case series study which enrolled 28 patients with mild PCO and good baseline best-corrected visual acuity (BCVA). All patients underwent a complete ophthalmologic examination, including SD OCT RNFL thickness measurement prior to Yag laser capsulotomy. Following laser intervention, all patients repeated the same complete ophthalmic examination and results were recorded and analysed. Results Mean RNFL thickness showed a significant postoperative increase from 89.6 to 94.1 mu m (p = 0.01), which was also confirmed for superior (p = 0.041), nasal (p = 0.011) and inferior quadrants (p = 0.032). SS and BCVA were also significantly increased after laser treatment (p < 0.01). A significant positive correlation was observed between SS and mean RNFL thickness postoperatively (p = 0.043) but not preoperatively (p = 0.059). Similarly, a significant relationship was found between BCVA and average RNFL thickness after (p = 0.017) but not before (p = 0.457) laser intervention. Conclusions Our study suggests that the presence of even mild PCO may alter the sensitivity of SD-OCT acquisition and lead to inadvertent RNFL thickness underestimation. Clinicians should be alerted to this contingency and take it into consideration when evaluating various optic neuropathies with SD OCT, in pseudophakic eyes

Optic disc drusen mimicking Idiopathic Intracranial Hypertension (IIH): rely on ultrasound

Abstract Optic nerve ultrasound is an established routine supplementary diagnostic tool for idiopathic intracranial pressure but it can also be helpful in avoiding misdiagnoses. We describe a case of an obese 15- year-old girl with persistent headaches, fundoscopic findings suggesting papilledema, normal brain imaging who underwent two lumbar punctures with unremarkable cerebrospinal fluid findings before ultrasound revealed optic disc drusen as the cause of the optic disc elevation
