Determination of the Sensitivity and Specificity of a Smartphone Application to Detect Retinoblastoma

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	N/A - 7 Years
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03016156
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

This study will utilize three strata called Stratum I, Stratum II and Stratum

III. STRATUM I - Infants and children known to have leukocoria who have been diagnosed with retinoblastoma, cataracts or glaucoma or other eye conditions.

Participants enrolled on Stratum I of the study will have the CRADLE application used by the doctor during their appointment. The participant will look straight forward while the doctor stands about 1-3 feet away holding the device that has the CRADLE application. He or she will slowly move the device up, down, middle, right, and left

- both in a lit and dimmed room.

The participant will be videotaped and photographed during this appointment. The doctor will record the results as determined by CRADLE ("normal" or no leukocoria versus "abnormal" or positive for leukocoria). STRATUM II

- Infants and children who are referred to an eye doctor to evaluate for leukocoria.

Participants enrolled on Stratum II of the study will be asked to look straight forward while he or she uses the CRADLE application (using the best method determined from Stratum I). The doctor will also examine the participant's eyes with the ophthalmoscope method. The results from both CRADLE and the ophthalmoscope method will be recorded and compared (white eye present versus absent, and normal versus abnormal as described above). STRATUM III

- Infants and children receiving treatment for retinoblastoma.

For participants enrolled on Stratum III, he or she will have the same procedures as described in Stratum

II. After receiving informed consent, participants will undergo evaluation by ophthalmoscope and CRADLE on Day 1.

Stratum III participants only will also undergo CRADLE evaluation on Days 2, 3, and 4.

Arms & Interventions

Arms

Experimental: Stratum I: Initial Evaluation Group

Initially, a small group of patients diagnosed with congenital or infantile cataracts, congenital glaucoma or retinoblastoma and who meet the eligibility criteria will undergo testing with CRADLE on Day 1.

Experimental: Stratum II: Leukocoria Evaluation Group

A separate group of participants who are referred for evaluation of leukocoria or any other eye condition will undergo red reflex testing testing with CRADLE on Day 1.

Experimental: Stratum III: Retinoblastoma Group

A separate group of participants with known retinoblastoma and who are undergoing ocular salvage treatments will be screened with red reflex testing using direct ophthalmoscopy on Day 1. They will also undergo testing with the CRADLE software application defined as the most effect in Stratum I on Day 1 then for three additional consecutive visits which typically occur every 3 to 4 weeks.

Interventions

Other: - CRADLE

A smartphone software application designed to detect leukocoria using a sophisticated photoluminic analysis. The investigator or designee will perform tests with CRADLE in separate patient cohorts with known diagnosis of retinoblastoma, congenital glaucoma, or cataracts.

Other: - Red reflex testing

Traditional red reflex testing for leukocoria using a direct ophthalmoscope on routine eye examination. Red reflex testing via direct ophthalmoscope will be performed before dilation, using the ophthalmoscope held close to the examiner's eye, focused on the pupil, viewed at 12 to 18 inches from the patient's eyes, with the room lights dimmed, in accordance with the American Academy of Pediatrics guidelines.
