Olson, Randall J. | Clinical comparison of single-piece and three-piece truncated hydrophobic acrylic intraocular lenses | PURPOSE: To determine the clinical differences between three-piece (3P) and single-piece (SP) truncated hydrophobic acrylic intraocular lenses (IOL). DESIGN: Retrospective cohort clinical study. METHODS: The setting was an academic clinical practice. The patient population consisted of subjects with... | Lenses, Intraocular; Patient Satisfaction; Postoperative Complications; Prosthesis Design; Visual Acuity | 2003-10 |

Drews, Frank; Westenskow, Dwayne R.; Bermudez, Julio Cesar; Syroid, Noah Daniel; Agutter, James A.; Strayer, David Lee | Evaluation of a cardiovascular display in a high fidelity simulator | Human error in anesthesia can be attributed to misleading information from patient monitors or to the physician's failure to recognize a pattern. A graphic representation of monitored data may provide better support for detection, diagnosis, and treatment. We designed a graphic display to show hemod... | Patient monitors; Visual information; Graphic displays | 2003 |

Normann, Richard A.; Horch, Kenneth W.; Cha, Kichul | Mobility performance with a pixelized vision system | A visual prosthesis, based on electrical stimulation of the visual cortex, has been suggested as a means for partially restoring functional vision in the blind. The prosthesis would create a pixelized visual sense consisting of punctate spots of light (phosphenes). The present study investigated the... | Visual Prosthesis; Mobility; Phosphene Simulator | 1992 |

Olson, Randall J.; Pingree, Michael F.; Lundergan, Maureen K. | Penetrating keratoplasty for keratoconus: a long-term review of results and complications | PURPOSE: To study the long-term complications of penetrating keratoplasty (PKP) to evaluate current recommendations to patients with keratoconus. SETTING: John Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. METHODS: Retrospective study of all PKP procedures for keratoconus performe... | Visual Acuity; Refraction, Ocular; Keratoconus; Astigmatism | 2000-07 |

Angelucci, Alessandra | Role for nitric oxide in the development of the ferret retinogeniculate projection | The ferret retinogeniculate projection segregates into eye-specific layers during the first postnatal week and into ON/OFF sublaminae, which receive inputs from either on-center or off-center retinal ganglion cells, during the third and fourth postnatal weeks. The restriction of retinogeniculate axo... | Enzyme Inhibitors; Visual Pathways; Wheat Germ Agglutinin-Horseradish Peroxidase Conjugate | 1996 |

Horch, Kenneth W.; Normann, Richard A. | Simulation of a phosphene field based visual prosthesis | A visual prosthesis for the blind based upon electrical stimulation of the visual cortex requires the development of an array of electrodes. To establish design specifications for such an electrode array, we have conducted psychophysical experiments with normally sighted subjects wearing a portable... | Visual prosthesis; Phosphene simulator | 1990 |

Swallow, Charles E.; Tsuruda, Jay S.; Digre, Kathleen B.; Glaser, Matthew J.; Davidson, H. Christian; Harnsberger, H. Ric | Terson syndrome: CT evaluation in 12 patients. | PURPOSE: Terson syndrome may be overlooked in the acute setting and often requires ophthalmologic intervention to prevent long-term visual loss. In this syndrome, vitreous or retinal hemorrhage results from an abrupt rise in intracranial pressure, leading to retinal venous hypertension and intraocul... | Retinal Hemorrhage; Visual Acuity; Vitreous Hemorrhage | 1998-04 |
