Eye Tracking of Pitched Balls
The purpose of this study is to compare eye and head movement behavior when baseball batters swing at (but do not hit) an approaching ball and when batters judge the height above the ground at which an approaching ball would reach had it arrived at the batter.
- Must have visual acuity of 20/20 in each eye
- No eye turn
- Depth perception of 60 seconds of arc
- Must have played organized baseball or softball at the high school level or above within the last 10 years
A Study about a FDA Approved Contact Lenses for Management of Myopia
The purpose of this study is to evaluate if FDA approved contact lenses can reduce the progression of nearsightedness in children. Children who participate in this 4-year study will be asked to wear the study provided contact lenses at least 6 days a week and be willing to attend visits at The OSU College of Optometry one month after starting treatment and every six months thereafter. Visits will include a comprehensive eye exam and contact lens fitting at no cost.
- Children ages 8 to 12 years old.
- No previous medication or contact lenses related to myopia control.
- Glasses and/or contact lens prescription between -0.75 and -4.00 diopters.
- Satisfy all other study eligibility criteria.
Determining the Best Glasses Prescription for Children with Down Syndrome
The purpose of this study is to examine whether we can use an instrument that measures how the eye focuses light to determine the best glasses prescription.
- Children with Down syndrome age 5 to 17 years
- Able to do vision tests by naming or matching shapes or letters
- Able to look at lights for short periods of time
- No nystagmus (uncontrolled eye movements when trying to look at things)
- Safe to dilate the eyes - we will screen medical history, eye health, and allergies to determine this
- No scars on the front of the eye
- No cataracts
- No eye diseases like glaucoma or retinal problems
Evaluation of Hand/Eye Coordination with Multifocal Contact Lenses Compared to Progressive Addition Spectacles
This study is looking to compare the use of multifocal contact lenses to progressive-addition (no-line bifocal) glasses. Participants will be asked to perform a hand/eye coordination task once while wearing glasses, and once while wearing contact lenses.
The duration of the study lasts 1 hour.
- Must currently have presbyopia (unable to focus on objects at near).
- Must have up-to-date pair of progressive-addition glasses (addition power of +1.50 D or higher), worn for at least 2 weeks prior to screening visit.
- Must be a wearer of multifocal contact lenses.
- Meet other study eligibility criteria.
A Study about Eye Teaming, Focusing Ability and Quality of Life
The purpose of this study is to assist in development of a new quality of life survey that can be used to learn more about how eye teaming, focusing ability and eye movement problems affect a child’s life.
- Children experiencing eye teaming, focusing, and eye movement problems (with recent concussion or non-concussed)
- Children with amblyopia (lazy eye) are excluded
A Randomized Trial to Evaluate Sequential vs Simultaneous Spectacles plus Patching for Amblyopia in Children 3 to <13 Years Old
The purpose of this study is to evaluate if treating amblyopia (lazy eye) with glasses and patching at the same time improves vision as well as treating amblyopia first with glasses and then with patching, if needed.
- Visual acuity in the amblyopic eye between 20/40 and 20/200
- No previous treatment for amblyopia, including glasses or contact lenses
- Amblyopia (lazy eye) in one eye
Tear Film in Children Study
The goal of this study is to describe the risks associated with overnight orthokeratology contact lens wear in children by identifying corneal and tear film changes. The study aims to describe and compare the tear film components in a pediatric sample wearing orthokeratology contact lenses (used to change the shape of the cornea), soft contact lenses, or glasses. Additionally, the study aims to compare the corneal thickness profile in a pediatric sample wearing orthokeratology contact lenses, soft contact lenses, or glasses.
This study requires one visit only. The overall timeline from subject recruitment to study completion is dependent upon subject and examiner availability and scheduling. As long as no changes occur to subject eligibility between initial recruitment and the study visit, there is some flexibility with timing.
- Near-sighted prescription between -1.00D and -6.00D
- Current correction with glasses, soft contact lenses, or overnight orthokeratology contact lenses
- Has been wearing current correction for 6 months or longer
- Good eye and overall health
A Study About the Development of Learning in African-American/Black Children
The purpose of this study is to investigate the early development of attention, learning, and memory during childhood. Participation in this study includes 4, 90-minute-long visits to the lab per year. During these visits, your child will play 2-3 fun, computerized games. These games are designed to assess various aspects of their cognitive ability.
The duration of the study will last 4 years.
Eligibility Criteria:
- African-American/Black children who are 4 years old
A Study to Examine Atropine for the Reduction of Nearsightedness (The CHAPERONE Study)
The purpose of this study to test the safety and effectiveness of atropine 0.1% and atropine 0.01% eye solutions. These drugs are being tested to see if they slow the worsening of nearsightedness. Children who participate in this study will be asked to use their assigned study medication every night and willing to attend visits at The Ohio State University of Optometry 1 month after starting treatment. These visits will continue for 6 months until the duration of the study ends. This study will take place over a 4-year time period.
· Children aged 3 to < 13 years old. · No previous use of medications related to myopia control. · Glasses and/or contact lens prescription between -1.00 and -6.00 diopters. Interested guardians who believe their child may be eligible should contact study coordinators to further determine eligibility
Reviewing and Evaluating Resources Related to Dizziness and Home Based Therapies
The purpose of this study is to look at a web-based tool on the topic of dizziness so that we can create resources for teaching patients about causes of dizziness and home-based therapies. We are recruiting patients with dizziness and/or general volunteers to review the web-based tool and then provide feedback which will then be used to help update requirements for the educational tool. This study will take about 20-30 minutes of your time to review a website and complete a survey. If you decide to also participate in the discussion, it will take about 20-30 more minutes.
- Participants must be 18 years or older - able to speak and read English at an eighth-grade level or above - be willing and able to participate
