Trial summary

Retinopathy of prematurity (ROP) is a major cause of blindness in the world. Initial ocular examinations of infants at risk for ROP are generally conducted between 4-6 weeks postnatally. These exams are vital to protect preterm infants from blindness, but these exams have been shown to cause pain in this population. Read more about this study

About this study

Official title: Retinopathy of Prematurity Screening: Comparison of Pain Using Two Eyelid Retractors

Retinopathy of prematurity (ROP) is a major cause of blindness in the world. Initial ocular examinations of infants at risk for ROP are generally conducted between 4-6 weeks postnatally. These exams are vital to protect preterm infants from blindness, but these exams have been shown to cause pain in this population.

Currently two speculums are utilized; the spring loaded Alfonso and the screw loaded Cook eyelid speculum. There is no schedule for who receives which speculum during their exam.

The objective of this study is to evaluate the pain response in the neonatal population, 32 weeks or less, and less than or equal to 1500 grams, undergoing a retractor eye exam for retinopathy of prematurity (ROP) screening.

The primary study aim is to compare the N-PASS pain score between neonates who received a ROP eye exam with the spring loaded Alfonso and the screw loaded Cook eye speculums.

Read the detailed description

Retinopathy of prematurity (ROP) is a major cause of blindness in the world. It is a vasoproliferative retinopathy that affects premature and low birth-weight infants. Initial ocular examinations of infants at risk for ROP are generally conducted between 4-6 weeks postnatally. These exams are vital to protect preterm infants from blindness, but these exams have been shown to cause pain in this population.

Only two studies alluded to the impact of the eyelid speculum on the pain response and score. Specifically, Hered and Gyland, questioned whether the Alfonso, spring loaded, eyelid lid speculum due to its forceful opening of the eyelid causes more pain. However, no studies were found that included the type of eyelid speculum as a variable of study. In addition, no studies have compared the effect of different eyelid speculums on the pain response.

Currently two speculums are utilized; the spring loaded Alfonso and the screw loaded Cook eyelid speculum. There is no schedule for who receives which speculum during their exam. The investigators team recognizes that the insertion of the eyelid speculum causes a pain response in these infants and would like to determine if there is a difference in the level of that response between the two speculums.

The investigators study will test the difference in pain response when using either a spring loaded eyelid speculum or screw loaded speculum during an ROP exam on premature infants.

The objective of this study is to evaluate the pain response in the neonatal population, 32 weeks or less, and less than or equal to 1500 grams, undergoing a retractor eye exam for retinopathy of prematurity (ROP) screening.

The primary study aim is to compare the N-PASS pain score between neonates who received a ROP eye exam with the spring loaded Alfonso and the screw loaded Cook eye speculums.

What is being measured

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

  1. N-PASS Score immediately after the second eye

    With each exam, an N-PASS score will be recorded: just prior to the start of the exam; between each eye; at the end of the exam and every minute for five minutes from the completion of the exam.

    Measured: 5 minutes

Secondary outcomes (2)
  1. time it takes for neonates pain score to return to baseline or up to 5 minutes after the end of the exam

    Time in seconds will be recorded via stopwatch for the entire eye exam, starting with the insertion of the eyelid speculum in the right eye and concluding when the eyelid speculum is removed from the left eyelid.

    Measured: 5 minutes

  2. Maximum pain score recorded

    With each exam, an N-PASS score will be recorded: just prior to the start of the exam; between each eye; at the end of the exam and every minute for five minutes from the completion of the exam.

    Measured: 5 minutes

Questions about this trial

What is this clinical trial studying?

An observational study of Pain During ROP Exam, run by Wake Forest University Health Sciences at 1 site in United States.

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 4 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: stopped early, as of the sponsor's last update on 23 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study was stopped early (reason given: Medical Leave of Absence of the Principal Investigator and study team changes). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

N-PASS Score immediately after the second eye (time frame: 5 minutes). 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 NCT02152046, which also lists 2 linked publications.

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 23 Jan 2025.
