What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a smartphone app called CRADLE to help detect leukocoria in children. The app takes pictures of the eyes and looks for signs of this condition. It aims to improve early detection in kids who have or might have serious eye diseases.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on using a smartphone app for detection, so it's unlikely to require changes to your medication.

Is the smartphone app for detecting retinoblastoma safe to use?

The smartphone app for detecting retinoblastoma is safe as it is non-invasive, meaning it doesn't require any medical procedures or drugs, and it uses photographs to help identify eye conditions.12345

How does the smartphone app treatment for retinoblastoma differ from other treatments?

The smartphone app treatment for retinoblastoma is unique because it allows for early detection of the condition through a simple, non-invasive method using a smartphone camera to identify leukocoria (white pupil) in photographs. This approach is more accessible and affordable compared to traditional methods that require specialized equipment and healthcare professionals.12567

What data supports the effectiveness of the treatment CRADLE, White Eye Detector, ComputeR Assisted Detector of LEukocoria, Red reflex testing, Red Reflex Test, Ophthalmoscope Examination for detecting retinoblastoma?

Research shows that the CRADLE app, also known as the White Eye Detector, can identify leukocoria (white pupil) in photos, detecting eye disorders like retinoblastoma up to 1.3 years before diagnosis. This app, along with red reflex testing, helps in early detection, which is crucial for better outcomes.12358

Are You a Good Fit for This Trial?

This trial is for patients with retinoblastoma, congenital cataracts, or glaucoma who are visiting St. Jude Children's Research Hospital or University of Tennessee Hamilton Eye Institute. It includes new or minimally treated retinoblastoma cases and those referred for eye conditions like leukocoria.

Inclusion Criteria

I have a diagnosis of cataracts, glaucoma, or retinoblastoma and am seeing an eye specialist at St. Jude or UT.
Stratum II: Patient without prior diagnosis has been referred for ophthalmological evaluation, including leukocoria or other conditions.
I am receiving treatment to save my eye from retinoblastoma.

Exclusion Criteria

I have had treatment for cataracts or glaucoma.
I am unable or unwilling to give consent for the study.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

1-2 weeks

Initial Evaluation

Participants undergo initial evaluation using the CRADLE application and ophthalmoscope to assess leukocoria

1 day
1 visit (in-person)

Follow-up Evaluation

Participants in Stratum III undergo additional CRADLE evaluations on Days 2, 3, and 4 to compare with ophthalmoscope results

4 days
3 visits (in-person)

Follow-up

Participants are monitored for safety and effectiveness after initial evaluations

3-4 weeks

What Are the Treatments Tested in This Trial?

Interventions

  • CRADLE
  • Red reflex testing
Trial Overview The study tests the CRADLE smartphone app's ability to detect leukocoria compared to traditional red reflex testing using an ophthalmoscope. The trial has two parts: finding the best way to use CRADLE and measuring its accuracy (sensitivity and specificity).

Published Research Related to This Trial

The red-reflex test is significantly more effective at detecting simulated retinoblastoma lesions when using oblique viewing and pupil dilation, with detection rates improving from less than 48% to 96% for larger lesions.
Detection rates for peripheral lesions were notably low with straight-on viewing (as low as 16%), but improved to 70% or higher with oblique viewing, highlighting the importance of viewing technique in identifying potential retinoblastoma.
The detection of simulated retinoblastoma by using red-reflex testing.Li, J., Coats, DK., Fung, D., et al.[2010]
The modified MDEyeCare app successfully detected leukocoria in early stages of retinoblastoma (RB) in 50% of cases in Group B and 83% in Group C, indicating its potential for early diagnosis by non-ophthalmologists.
In late-stage RB cases, the app achieved a 100% detection rate, suggesting that the improved smartphone methodology could lead to better treatment outcomes and vision preservation for affected children.
Smartphone-based application improves the detection of retinoblastoma.Khedekar, A., Devarajan, B., Ramasamy, K., et al.[2021]
The EyeScreen smartphone application demonstrated a high sensitivity of 87% and specificity of 73% in detecting leukocoria, indicating its potential as an effective screening tool for retinoblastoma in low-income regions.
This study, involving 1,457 participants in Ethiopia, highlights the promising use of low-cost technology and machine learning to improve early diagnosis of retinoblastoma, which is crucial for better clinical outcomes.
