Binocular Dig Rush Game Treatment for Amblyopia (ATS20)
PI:
Jason Peragallo, MD
Job Title:
Principal Investigator
Coordinator:
Judy Brower
Status:
Not yet enrolling

General Summary:
This study is to compare results of 1 hour per day binocular game play 5 days each week, wearing correct glasses if needed, with wearing correct glasses only for treatment of amblyopia in children 4 years of age to less than 13 years of age. Eligible children will be randomly assigned to one of two groups:

1. Binocular treatment group: Binocular computer game play (wearing correct glasses) for 1 hour each day, 5 days a week (may split into shorter sessions totaling 1 hour)
2. Continue wearing correct glasses, if glasses are needed

Patients in the computer game group will be given an iPad with the game on it which will be returned during the 8 week exam. If a patient is randomized to glasses only and at the end of 8 weeks still remains amblyopic, they will be offered the iPad with the game to play for 8 weeks, then must return at the 16 week visit for an eye exam and to return the iPad.

The computer game is played with a special glasses (over glasses, if glasses have been prescribed).

Clinical Summary:
Study patients will be examined at enrollment, week 4, and week 8. Those initially assigned to glasses only who choose to play the game at the 8 week visit will return at 16 weeks to have their visual acuity checked and to return the iPad.

Red/Green glasses are worn during game play. The contrast of images seen by the amblyopic eye (through the green filter) will be at 100%. The contrast of images seen by the fellow eye (through the red filter) will begin at 20% and will increase or decrease automatically based on game performance and duration of game play.

Some images are seen only through the red lens while others are seen only through the green lens. The contrast (brightness) of the images in the game will vary depending on the severity of the amblyopia.

Inclusion Criteria:
• Age 4 to less than 13 years
• No amblyopia treatment other than optical correction in the past 2 weeks
• Current glasses based on cycloplegic refraction within last 7 months
• Correct glasses must have been worn for at least 16 weeks OR vision stable on 2 consecutive exams at least 8 weeks apart
• Visual acuity on research machine must be within a certain range
• If heterotropia exists, near deviation must be less than or equal to 5 prism diopters
• Must be able to play the Dig Rush game while wearing the special glasses (over current glasses, if applicable)

Exclusion Criteria:
• Patient has telephone and is willing to be contacted by the study staff
• Prism in glasses (may participate if prism discontinued at least 2 weeks before enrollment
• Myopia greater than -6.00 spherical equivalent in either eye
• Previous intraocular or refractive surgery
• Any treatment for amblyopia (including patching, atropine, Bangerter filter, vision therapy or previous binocular treatment) during past 2 weeks before enrollment
• No Down Syndrome or cerebral palsy
• No severe development delay that would interfere with treatment or evaluation (in opinion of investigator). Mild speech delay or reading and/or learning disabilities are not excluded

Pediatric Optic Neuritis Prospective Outcomes Study
PI:
Jason Peragallo, MD
Coordinator: Judy Brower
Status: Enrolling

General Summary: This is not a treatment study. This is to determine whether enough subjects in this age group with optic neuritis can be enrolled into a clinical trial. The study will look at visual acuity at certain time points after the diagnosis of pediatric optic neuritis is confirmed. It will help to estimate the risk of developing optic neuritis in the fellow eye within 2 years after enrollment (if initially present in one eye). It will also help to estimate the risk of developing multiple sclerosis 2 years after enrollment.

Clinical Summary:
Treatment is standard of care for this condition. Visits will be Enrollment, 1 month, 6 months, 1 year, and 2 years. More visits may be required if needed for standard of care. Visual acuity will be checked by a different method that is typically used here. There are some questionnaires that will be administered as part of the study.

Inclusion Criteria:

• 3 to less than 16 years of age.
• Optic neuritis in at least one eye.
• Visual loss and/or pain with eye movements for 2 weeks or less.
• There are certain eye exam findings that must be met.
• MRI of the orbits must have been done with certain findings OR will be done in the next 2 weeks as standard of care (not part of the study).

Exclusion Criteria:
• Planning to move out of the area within the next 2 years and follow up at another study center is not possible.
• Previous episode of optic neuritis in the same eye.
• Lab findings that suggest a condition other then optic neuritis.
• A condition in the affected eye(s) that might affect visual acuity.

A Prospective Observational Study of Adult Strabismus
PI: Jason Peragallo, MD
Coordinator: Judy Brower
Status: Enrolling

General Summary:
This study is looking at 3 common causes and treatments of new onset adult strabismus (Misalignment of the eyes). This observational study will help to describe clinical characteristics, treatments, and one year outcomes of the following conditions: Convergence Insufficiency, Divergence Insufficiency, and Small Angle Hypertropia. Testing at study visits will include visual acuity, ocular alignment (measuring how much an eye turns in, out, or up), how well the eyes can work together, and questionnaires. The protocol does not dictate the treatment, the physician will treat as standard of care.

• All patients must be 18 years or older.
• Visual acuity 20/50 or better in each eye.
• Physician feels that condition is ready to treat.
• Recommended treatment has not been used within the past year.
• Physician ready to treat with prisms, orthoptic exercises, botulinum, or surgery.

In addition to the criteria above, each condition has additional criteria:

If condition is Convergence Insufficiency:
• No eye muscle surgery in past 10 years.
• No constant exotropia at distance or near.

If condition is Divergence Insufficiency:
• No eye muscle surgery in the past.
• Double vision in the distance.

If condition is Hypertropia:
• No eye muscle surgery in the past.
• Double vision at distance or near.

Exclusion Criteria:
• Paralytic, paretic, or restrictive eye muscle problems.

Pediatric Ophthalmology: Phase 1 Trial of Bevacizumab Treatment for Severe Retinopathy of Prematurity
PI:
Amy Hutchinson, MD
Coordinator:
Judy Brower, COMT, 404-778-4725
Status:
Enrolling

General Summary:
The purpose of this study is to determine a lower dose of Bevacizumab currently used for severe Retinopathy of Prematurity that is effective and can be tested in larger studies in the future.

Clinical Summary:
In-patient premature infants will be enrolled and will receive a single intraocular injection of Bevacizumab at a dose lower than usually given determined by the protocol. If the eye does not show improvement additional standard of care treatment may be given. Exams will be performed the day after treatment, weekly for 4 weeks, and more often if needed.

There will be one follow up visit in the clinic at one year (gestational age). There is an optional blood draw before treatment, 2 and 4 weeks after treatment to help determine amounts of VEGF and Avastin.

Inclusion Criteria:
• Type 1 Retinopathy of Prematurity
• No previous treatment for Retinopathy of Prematurity in the study eye and no previous Bevacizumab in the non-study eye.

Exclusion Criteria:
• Nasal lacrimal duct obstruction

Pediatric Cataract Surgery Outcomes Registry
PI: Phoebe Lenhart, MD
Coordinator: Judy Brower, COMT
Status: Closed to Enrollment

GeneralSummary: A national registry is being formed to collect information about cataract surgery performed on children less than 13 years of age. Within 45 days after surgery, parent will be asked if they would like to enroll their child. This registry is for data collection only, there are no study visits or study procedures. The only study test performed is the visual acuity at 5 years. Each year for 5 years the patient record will be reviewed and information collected. Some common complications for cataract surgery in children include clouding of the capsule requiring laser treatment, retinal detachment, amblyopia (decreased vision in that eye), glaucoma, unequal vision in the two eyes.

The incidence, risk factors, and natural history of these events that affect vision have not been studied in a large group.

Inclusion Criteria:
– Less than 13 at time of surgery

Exclusion Criteria:
– Follow-up at the study center not possible
