  • An Adjustable Magnetic Levator Prosthesis for Customizable Eyelid Reanimation in Severe Blepharoptosis II: Randomized Evaluation of Angular Translation

    Friday, December 01, 2023
    Author(s): Pooyan Tirandazi,Melanie Nadeau,Russell L Woods,Eleftherios I Paschalis,Kevin E Houston
    Source: Translational vision science & technology
    CONCLUSIONS: Angular translation provided adjustable force, which had a statistically and clinically meaningful impact on eye opening and the completeness of the spontaneous blink. This quantitative evidence supports continued use of the angular translation mechanism for force adjustment in the customizable magnetic correction of severe blepharoptosis.

    Friday, November 17, 2023
    Author(s): Shrinivas Pundlik,Matteo Tomasi,Kevin E Houston,Ayush Kumar,Prerana Shivshanker,Alex R Bowers,Eli Peli,Gang Luo
    Source: Investigative ophthalmology & visual science
    CONCLUSIONS: All groups demonstrated compensatory scanning, making more gaze scans with larger magnitudes to the blind side. Mild to moderate LHSN adversely impacted the scanning rate.
  • Clinical Report: Clinician Feedback on the Magnetic Levator Prosthesis

    Friday, October 27, 2023
    Author(s): Kevin E Houston,Melanie Nadeau,Eleftherios I Paschalis
    Source: Optometry and vision science : official publication of the American Academy of Optometry
    CONCLUSIONS: This clinical report suggests that the main barriers to clinical success of the MLP may be cost and insurance coverage, appearance of the device, and self-application. Possible solutions are cost-benefit analysis research, engineering efforts to reduce spectacle magnet size and improve the ease of eyelid magnet application.

    Source: Archives of rehabilitation research and clinical translation
    CONCLUSIONS: Data support the feasibility of this inpatient eye and vision rehabilitation care pathway which may be used as a foundation for creating or refining similar programs elsewhere. Uniform administration of IRF-based visual neuro-rehabilitation care could provide a substrate for future clinical trials to evaluate efficacy.
  • Effects of Perceptual-motor Training on Collision Judgments with Peripheral Prism Expanded Vision

    Tuesday, January 03, 2023
    Author(s): Kevin Edward Houston,Eli Peli,Gang Luo,Alex R Bowers,Russell L Woods
    Source: Optometry and vision science : official publication of the American Academy of Optometry
    CONCLUSIONS: P-prisms improved detection, but collision judgments were inaccurate when seen only via the p-prisms and did not improve with perceptual-motor training. Patients should continue to be advised to turn their head and eyes to fixate the hazard after detection.
  • Feasibility of Magnetic Levator Prosthesis Frame Customization Using Craniofacial Scans and 3-D Printing

    Friday, October 21, 2022
    Author(s): Kevin E Houston,Eleftherios I Paschalis

    CONCLUSIONS: In patients complaining of blurry vision, a careful evaluation of the stability of accommodation is indicated.
  • Inpatient Virtual Vision Clinic Improves Access to Vision Rehabilitation Before and During the COVID-19 Pandemic

    Monday, December 28, 2020
    Author(s): Matthew Keilty,Kevin E Houston,Caroline Collins,Ritika Trehan,Ya-Ting Chen,Lotfi Merabet,Amy Watts,Shrinivas Pundlik,Gang Luo
    Source: Archives of rehabilitation research and clinical translation
    CONCLUSIONS: The virtual vision clinic process improved inpatient access to eye and visual neurorehabilitation assessment before and during the COVID-19 quarantine and was well accepted by providers and patients.
  • Measuring Virtual Reality Headset Resolution and Field of View: Implications for Vision Care Applications

    Monday, August 10, 2020
    Author(s): Marissa Howard Lynn,Gang Luo,Matteo Tomasi,Shrinivas Pundlik,Kevin E Houston
    Source: Optometry and vision science : official publication of the American Academy of Optometry
    CONCLUSIONS: The minimum angular resolution in logMAR of current VR technology is insufficient for visual acuity testing and may be insufficient for standalone treatment of amblyopia. Field of view during movie watching or gaming is about half that reported by manufacturers but adequate for some types of visual field testing. Use for vergence testing and training is a concern for headsets with long eye-to-screen distance or interpupillary distances
  • Peripheral Prisms Improve Obstacle Detection during Simulated Walking for Patients with Left Hemispatial Neglect and Hemianopia

    Saturday, September 01, 2018
    Author(s): Kevin E Houston,Alex R Bowers,Eli Peli,Russell L Woods
    Source: Optometry and vision science : official publication of the American Academy of Optometry
    CONCLUSIONS: Within the controlled conditions of this simulated, collision judgment task, patients with left neglect responded well to initial application of p-prisms exhibiting improved detection and wider safety margins on the side of the HVFD that did not differ from non-neglect patients. Further study of p-prisms for neglect patients in free-gaze conditions after extended wear and in real-world mobility tasks is clearly warranted.

    Wednesday, January 24, 2018
    Author(s): Kevin E Houston,Eli Peli,Robert B Goldstein,Alex R Bowers
    Source: Translational vision science & technology
    CONCLUSIONS: P-prisms improved detection with no negative effects, and training may provide additional benefit.
  • Patching for Diplopia Contraindicated in Patients with Brain Injury?

    Wednesday, August 31, 2016
    Author(s): Kevin E Houston,A M Barrett
    Source: Optometry and vision science : official publication of the American Academy of Optometry
    CONCLUSIONS: Because more peripheral parts of the visual field increasingly project to the contralateral superior colliculus with the temporal crescent being entirely contralateral, avoiding patching of the temporal crescent was advised, and in most cases can be achieved by taping off the spectacle lens and avoiding an elastic eye patch.
  • Restoration of Vision After Brain Injury Using Magnet Glasses

    Wednesday, August 24, 2016
    Author(s): Kevin E Houston,Eleftherios I Paschalis,Danielle C Angueira,P Matthew Bronstad,Anna M Barrett,Mary Alexis Iaccarino
    Source: American journal of physical medicine & rehabilitation
    Visual impairments are common after traumatic brain injury (TBI) and negatively affect quality of life. We describe a 39-year-old woman with a severe TBI who was evaluated by the inpatient optometry and vision rehabilitation service with findings of complete right homonymous hemianopia and right cranial nerve III palsy with 30-degree right exotropia (eye turn out) and complete right ptosis (eyelid will not open). The 30-degree exotropia advantageously generated 30 degrees of right visual field...
  • A Pilot Study of Perceptual-Motor Training for Peripheral Prisms

    Thursday, March 03, 2016
    Author(s): Kevin E Houston,Alex R Bowers,Xianping Fu,Rui Liu,Robert B Goldstein,Jeff Churchill,Jean-Paul Wiegand,Tim Soo,Qu Tang,Eli Peli
    Source: Translational vision science & technology
    CONCLUSIONS: Improved pointing accuracy for stimuli detected in prism-expanded vision of patients with hemianopia wearing 57Δ oblique p-prisms is possible and training appears to further improve detection.
  • Asymmetry in the Collision Judgments of People With Homonymous Field Defects and Left Hemispatial Neglect

    Tuesday, June 30, 2015
    Author(s): Kevin E Houston,Russell L Woods,Robert B Goldstein,Eli Peli,Gang Luo,Alex R Bowers
    Source: Investigative ophthalmology & visual science
    CONCLUSIONS: Left neglect was associated with rightward asymmetry in collision judgments, which may cause collisions on the left side even when an obstacle is detected. These behaviors may represent the spatial misperceptions in body midline described previously in patients with left neglect.
