  • Pediatric Perimeter-A Novel Device to Measure Visual Fields in Infants and Patients with Special Needs.
    Translational vision science & technology, 2017
    Co-Authors: Premnandhini Satgunam, Sourav Datta, Koteswararao Chillakala, Karthik R. Bobbili, Dhruv Joshi
    Abstract:

    PURPOSE There are no commercially available Devices to measure visual fields in infants. We developed a Device, "Pediatric Perimeter," that quantifies visual field extent (VFE) for infants. We describe the construction, validation, and use of this Device. METHODS A hemispherical dome with light emitting diodes (LEDs) was constructed. The LEDs were controlled using a computer program to measure reaction time (RT) to gross visual fields (GVF) and the VFE. Participants were tested in supine position in a dark room. Eye or head movement towards the stimuli was monitored with an infrared (IR) camera. Validation was done on 10 adults (mean age: 24.4 ± 5 years) with tunnel vision simulator. RESULTS Perimetry was performed on 19 infants (age: 2.3-12 months), five infants with normal milestones. GVF and VFE were estimated in 17 and 7 infants, respectively. Median RT of infants with developmental delay was 663 ms and 380 ms for healthy infants. Also, 14 children (age: 14 months-6 years) with developmental delay and five patients with cognitive impairment were tested. CONCLUSION Visual field isopter and RT can be examined with the Pediatric Perimeter Device on infants and patients with special needs. Further testing on infants will need to assess the repeatability. A large-scale study will be needed to compare typically developing infants and infants with delayed milestones with this Device. TRANSLATIONAL RELEVANCE Quantifiable parameters obtained with this Device can be used as outcome measures in clinical examination of infants and patients with special needs. This Device can be used in pediatric, neurology, and ophthalmology clinics.

  • Fine-Tuning the Evaluation
    Network Security Evaluation, 2005
    Co-Authors: Bryan Cunningham, Ted Dykstra, Ed Fuller, Matthew Hoagberg, Chuck Little, Greg Miles, Travis Schack, Russ Rogers
    Abstract:

    This chapter completes the technical portion of the INFOSEC Evaluation Methodology (IEM). The chapter performs an evaluation/analysis of all network Devices, including firewalls, routers, and IDSs. It conducts a password-compliance testing (also known as password cracking). The chapter also discusses application-specific scanning and the way it supplements the results from the vulnerability scans and host evaluations. The chapter examines the network protocol analysis and its role in the IEM. The IEM uses two approaches in the network Device analysis/evaluations. The design approach is an evaluation of the design of the Perimeter and the defenses for the organization. The technical approach is a technical evaluation of the various Perimeter Device configurations and settings.

  • Fine-Tuning the Evaluation
    The Best Damn IT Security Management Book Period, 2007
    Co-Authors: Susan Snedakar
    Abstract:

    This chapter completes the technical portion of the INFOSEC Evaluation Methodology (IEM). It details an evaluation and analysis of all network Devices, including firewalls, routers, and IDSs. It conducts password-compliance testing, also known as password cracking. It discusses application-specific scanning and how it supplements the results from vulnerability scans and host evaluations. It examines network protocol analysis and its role in the IEM. For the IEM, it uses two approaches in network Device analysis and evaluations. The design approach is an evaluation of the design of the Perimeter and defenses for the organization. The technical approach is a technical evaluation of the various Perimeter Device configurations and settings. The output of these two approaches combine to provide the evaluation team a comprehensive view of the Perimeter and Perimeter defenses and contribute to a more complete picture of the organization's overall INFOSEC posture.
