Outcome Measures

Primary Outcomes (2)

  • 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

    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.

Sampling MethodNon-Probability Sample
Study Population

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

You may qualify if:

  • 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

You may not qualify if:

  • Premature infants who received intravitreal injection of (Ranibizumab) less than one year or had any ocular pathology
