Plain-language summary
This study seeks to determine whether a smartphone application called CRADLE (ComputeR Assisted Detection of LEukocoria) has the potential to improve the detection of leukocoria. There will be no impact on participants' health outcome.
This study will be performed in two parts, each with a distinct cohort of patients.
Part 1 will assess the feasibility of various techniques/conditions for using CRADLE within patients known to have leukocoria.
Part 2 will estimate the sensitivity and specificity of CRADLE to detect leukocoria (using the techniques selected from information gathered in Part 1) as compared to an ophthalmoscope, within patients referred to the clinic for suspected leukocoria.
PRIMARY OBJECTIVES:
* To determine the most effective usage of a camera phone application (CRADLE) to maximize detection of leukocoria in patients with retinoblastoma, congenital cataracts, and glaucoma.
* To estimate the sensitivity and specificity of a camera phone application (CRADLE) in detecting leukocoria.

Inclusion Criteria - Stratum I:
* Patient has been diagnosed with congenital or infantile cataracts, congenital glaucoma, or retinoblastoma, and is scheduled for a visit with an ophthalmologist at St. Jude Children's Research Hospital or University of Tennessee Hamilton Eye Institute.
* Patient with retinoblastoma is newly diagnosed, or has received \< 2 cycles of chemoreductive therapy, and has not undergone enucleation.
* Patient with cataracts or glaucoma has not received any prior therapy.
Inclusion Criteria - Stratum II:
* Patient without prior diagnosis has been referred for ophthalmological evaluation, including leukocoria or other conditions.
Inclusion Criteria - Stratum III:
* Patient with retinoblastoma undergoing ocular salvage treatment.
Exclusion Criteria
* Prior treatment for cataracts or glaucoma
* Inability or unwillingness of research participant or legal guardian to consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
