  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Medical records of premature infants were collected from Egyptian Neonatal Network (EGNN) data base

Who may be able to join

  • premature infants who had a history of intravitreal injection of (Ranibizumab) not less than one year
  • Three control groups with age and sex matched were included for comparison. First group included premature infants who had ROP that regressed spontaneously without intervention. Second group was corresponded to premature infants who were diagnosed to have normal retinal vasculature from the first examination after birth. The third group belonged to full term babies

About this study

Official title: Refractive and Biometric Outcome Following Intravitreal Injection of Ranibizumab in Retinopathy of Prematurity: Long -Term Study

premature infants who had a history of intravitreal injection of (Ranibizumab) not less than one year were examined for refractive state and biometry

Read the detailed description

Medical records were collected in each group for birth history data, including gestational age (GA), birth weight (BW), and postmenstrual age (PMA) at time of intravitreal injection. The zone and stage of ROP were also recorded. All patients were evaluated for refractive errors and cycloplegic refraction was performed using a handheld auto keratorefractometer (Righton Retinomax K-plus2), and confirmed by retinoscopy examination. Refractive errors were calculated as spherical equivalent and astigmatism in cylinder. The average corneal radius of curvature was measured by handheld auto kerato-refractometer (Righton Retinomax K-plus2). The biometric optic components, including anterior chamber depth, lens thickness, and axial length, were measured using A-scan ultrasound (model Echoscan US-4000 / 500; Nidek)

    Also called Biometry

    Cycloplegic refraction and the average corneal radius of curvature were performed using a handheld auto kerato-refractometer (Righton Retinomax K-plus2). Refraction was confirmed by retinoscopy and refractive errors were calculated as spherical equivalent and astigmatism in cylinder.

What is being measured

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

  1. cycloplegic refraction

    Cycloplegic refraction and the average corneal radius of curvature were performed using a handheld auto kerato-refractometer (Righton Retinomax K-plus2). Refraction was confirmed by retinoscopy and refractive errors were calculated as spherical equivalent and astigmatism in cylinder

    Measured: 1 year after injection

  2. biometry

    The biometric optic components, including anterior chamber depth, lens thickness, and axial length, were measured using A-scan ultrasound (model Echoscan US-4000 / 500; Nidek). Examination under sedation was performed for uncooperative children.

    Measured: 1 year after injection

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

cycloplegic refraction (time frame: 1 year after injection). The study lists 2 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 NCT04537065, which also lists 10 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 3 Sep 2020.
