Blue and Red Light-Evoked Pupil Responses in Photophobic Subjects with TBI.

Purpose: Photophobia is a common symptom in individuals suffering from traumatic brain injury (TBI). Recent evidence has implicated blue light-sensitive intrinsically photosensitive retinal ganglion cells (ipRGCs) in contributing to the neural circuitry mediating photophobia in migraine sufferers. The goal of this work is to test the hypothesis that ipRGC function is altered in TBI patients with photophobia by assessing pupillary responses to blue and red light.

Vision Therapy for Binocular Dysfunction Post Brain Injury.

Purpose: To prospectively evaluate the effectiveness of home-based computer vergence therapy for the treatment of binocular vision disorders in adults at least 3 months after an acquired brain injury.

Methods: Eligibility criteria included presence of binocular dysfunction characterized by receded near point of convergence (≥6 cm break), insufficient positive fusional vergence at near (failing Sheard's criterion or <15△ blur or break), insufficient negative fusional vergence at near (<12△ blur or break), and/or reduced vergence facility at near (<15 cycles per minute with 12△BO/3△BI). Participants were prescribed 12 weeks of home-based computer vergence therapy.

A Survey of Presbyopic Contact Lens Wearers in a University Setting.

Purpose: To determine why presbyopic patients discontinue contact lens wear and describe their opinions of comfort and visual quality with contact lenses.

Methods: A survey assessing current age, gender, contact lens material/design, and opinions of contact lens comfort and visual quality was mailed to 2400 presbyopic patients (age 40 years and older) that have had eye exams in the Ohio State University College of Optometry's Contact Lens Services over the last 4 years.

Results: A total of 496 surveys were analyzed.

Contact Lens Corneal Inflammatory Events in a University Population.

Purpose: To identify the contact lens-related modifiable and nonmodifiable factors associated with corneal inflammatory events (CIEs) in a university eye care center.

Methods: Contact lens-wearing undergraduate and graduate/professional students (age range, 18 to 36 years) with CIEs and contact lens wearers without complications (non-CIEs) were surveyed about their age, education level, overnight wear, brand of lens, brand of care solution, storage case age, topping-off, and lens replacement. Logistic regression was used to assess the impact of participant characteristics (demographic and behavior) and contact lens factors on the risk of a CIE.

Who Says There's Nothing New under the Sun?

The time since our first publication in 2007 describing time spent outdoors as protective for juvenile myopia onset to clinical trials incorporating outdoor light interventions has been short. The time outdoors/myopia example highlights the incorporation of clinical or epidemiologic evidence to translational research that may eventually change clinical practice and/or behavior.

Can Binocular Vision Disorders Contribute to Contact Lens Discomfort?

Purpose: To determine the relationship between binocular vision (BV) disorder and dry eye symptoms and the frequency of BV disorders in subjects with contact lens-induced dry eye symptoms.

Methods: Subjects recruited for a larger dry eye study (n = 104) completed the Ocular Surface Disease Index (OSDI) and Convergence Insufficiency Symptom Survey (CISS) to determine if symptoms assessed on these two surveys were related. Also, myopic soft contact lens wearers (n = 29) with self-reported dry eye symptoms were recruited.

Associations with Meibomian Gland Atrophy in Daily Contact Lens Wearers.

Purpose: To determine associations for contact lenses (CLs) and meibomian gland atrophy in a matched-pair study.

Methods: Contact lens wearers (case) and age- and sex-matched non-contact lens (NCL) wearers with no history of CL use (control) were recruited for a multicenter study. All subjects were administered the Ocular Surface Disease Index questionnaire and a comprehensive battery of clinical tests (e.

Vision, training hours, and road testing results in bioptic drivers.

Purpose: Bioptic telescopic spectacles can be used by people with central visual acuity that does not meet the state standards to obtain an unrestricted driver's license. The purpose of this study was to examine the relationships among visual and demographic factors, training hours, and the results of road testing for bioptic drivers.

Methods: A retrospective study of patients who received an initial daylight bioptic examination at the Ohio State University and subsequently received a bioptic license was conducted.

Choroidal Thickness and Peripheral Myopic Defocus during Orthokeratology.

Purpose: To investigate whether significant thickening occurs in the human choroid in response to chronic peripheral myopic defocus during overnight orthokeratology.

Methods: Subjects were nine children 11 to 15 years old (mean [±SD] age, 13.61 [±1.

Guinea pig ciliary muscle development.

Purpose: The purpose of this study was to develop a method for quantifying guinea pig ciliary muscle volume (CMV) and to determine its relationship to age and ocular biometric measurements.

Methods: Six albino guinea pigs' eyes were collected at each of five ages (n = 30 eyes). Retinoscopy and photography were used to document refractive error, eye size, and eye shape.

Associations between hyperopia and other vision and refractive error characteristics.

Purpose: To investigate the association of hyperopia greater than +3.25 diopters (D) with amblyopia, strabismus, anisometropia, astigmatism, and reduced stereoacuity in preschoolers.

Methods: Three- to five-year-old Head Start preschoolers (N = 4040) underwent vision examination including monocular visual acuity (VA), cover testing, and cycloplegic refraction during the Vision in Preschoolers Study.

A method to monitor eye and head tracking movements in college baseball players.

Purpose: This study had two purposes. The first was to develop a method to measure horizontal gaze tracking errors (based on synchronized eye and head tracking recordings) as subjects viewed many pitched balls. The second was to assess horizontal eye, head, and gaze tracking strategies of a group of Division 1 college baseball players.

Ciliary muscle thickness in anisometropia.

Purpose: The purpose of this study was to investigate the relationships between ciliary muscle thickness (CMT), refractive error, and axial length both across subjects and between the more and less myopic eyes of adults with anisometropia.

Methods: Both eyes of 29 adult subjects with at least 1.00 D of anisometropia were measured.
