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)

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

Questions about this trial
What is this clinical trial studying?
An observational study of Retinopathy of Prematurity, run by Ameera Gamal Abdelhameed at 1 site in Egypt.
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 2 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: finished, as of the sponsor's last update on 3 Sep 2020. 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 Egypt. 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 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.
