Trial summary

Cataract (cloudiness of the lens) is the major cause of avoidable child blindness in the world and affects 1 in 3000 UK infants. Screening may fail to detect a cataract in an affected child (false-negative) or mistakenly suggest there is a cataract (false positive) triggering urgent unnecessary referral.

About this study

Official title: Can the Diagnostic Accuracy of Newborn Eye Screening for Congenital Cataract be Improved With Digital Dual Light Source Imaging? The Digital Imaging vs Ophthalmoscopy (DIvO)Study.

Cataract (cloudiness of the lens) is the major cause of avoidable child blindness in the world and affects 1 in 3000 UK infants. Screening may fail to detect a cataract in an affected child (false-negative) or mistakenly suggest there is a cataract (false positive) triggering urgent unnecessary referral.

Screening is currently undertaken using an ophthalmoscope into the eye to assess the reddish reflected light (red-reflex). This study aims to test if screening using a new hand-held digital imaging device (Neocam) is more accurate than the ophthalmoscope for newborn eye screening.

Read the detailed description

Cataract (cloudiness of the lens) is the major cause of avoidable child blindness in the world and affects 1 in 3000 UK infants. Cataracts are present in both eyes in more than half of the babies affected. Surgery is required by 8 weeks of age to prevent permanent visual impairment at this critical time of vision and brain development. All UK babies are examined (screened) for cataract twice within the first 8 weeks of life but late diagnosis continues to be a problem, causing avoidable visual impairment in some affected children.

Screening may fail to detect a cataract in an affected child (false-negative) or mistakenly suggest there is a cataract (false positive) triggering urgent unnecessary referral, parental anxiety and wasted NHS resources. Screening is currently performed by midwives and doctors shining a bright white light torch (an ophthalmoscope) into the eye to assess the reddish reflected light (red-reflex), similar to "red eye" seen in flash photos. Cataract causes a dark shadow on the red-reflex but the test can be difficult because bright light causes the pupils to constrict and the babies to forcefully shut their eyes. Assessment is particularly difficult in ethnic minority infants since eye pigmentation affects the hue and brightness of the red-reflex.

This study aims to test if screening using a new hand-held digital imaging device (Neocam) is more accurate than the ophthalmoscope for newborn eye screening. Neocam painlessly images the eye's reflection firstly to infrared light and then to a brief green light flash. Its infrared light causes no pupil constriction or avoidance response and the reflection is bright and consistent regardless of the baby's ethnicity. Its brief green flash and immediate imaging allows a photo of the red-reflex to be captured before the pupil has time to constrict.

To compare the accuracy of both tests, the investigators seek to enrol 140,000 newborn babies in a two year study period. All babies will have both the current ophthalmoscope screening test and additional Neocam imaging. If either test is potentially abnormal, the baby will be referred for specialist examination.

A more accurate screening test could prevent life-long disability and reduce costs to the NHS and society. This study will allow a future estimation of what these savings might be and whether changing to a digital imaging screening service might be justified. The result may have an impact on eye screening world-wide to prevent childhood blindness from cataract.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity of the screening evaluation of the Neocam (intervention) test

    The proportion of patients correctly identified as having cataract by a positive Neocam screening test result. Where a higher value indicates better sensitivity of the screening test for presence of cataract.

    Measured: 2 years

  2. Specificity of the screening evaluation of the Neocam (intervention) test

    The proportion of patients correctly identified as not having cataract by a negative Neocam screening test result. Where a higher value indicates better specificity of the screening test for absence of cataract.

    Measured: 2 years

  3. Sensitivity of the screening evaluation of the standard test

    The proportion of patients correctly identified as having cataract by a positive standard screening test result. Where a higher value indicates better sensitivity of the screening test for presence of cataract.

    Measured: 2 years

  4. Specificity of the screening evaluation of the standard test

    The proportion of patients correctly identified as not having a cataract by a negative standard screening result. Where a higher value indicates better specificity of the screening test for absence of cataract.

    Measured: 2 years

Secondary outcomes (1)
  1. Usability feedback

    Qualitative usability feedback and test preference using screener questionnaire.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Neocam in people with Congenital Cataract, run by Cambridge University Hospitals NHS Foundation Trust.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Louise Allen (07941666981, info@divostudy.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of the screening evaluation of the Neocam (intervention) test (time frame: 2 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05282147, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2022.
