Study Type: Interventional

Official Title: Serum Concentrations of Vascular Endothelial Growth Factor in Infants Treated With Ranibizumab for Retinopathy of Prematurity

Brief Summary: To determine the serum concentrations of ranibizumab and vascular endothelial growth factor (VEGF) in infants with retinopathy of prematurity (ROP) who received intravitreal ranibizumab

Detailed Summary: Infants with ROP are studied. They received 0.25 mg or 0.5 mg of intravitreal ranibizumab to either 1 eye (unilateral cases) or both eyes (bilateral cases) with vascularly active ROP. Serum samples are collected 1 day before and 1 day, 3 days, 1 week after intravitreal ranibizumab. The serum concentrations of ranibizumab and VEGF are measured by enzyme-linked immunosorbent assay, and the changes of the serum VEGF levels are determined.

Current Primary Outcome: The effect of intravitreal ranibizumab on serum VEGF level [ Time Frame: 1 day before and 1 day, 3 days, 1 week after intravitreal ranibizumab ]

the changes of the serum VEGF levels


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • The effect of intravitreal ranibizumab on weight [ Time Frame: corrected age of six month ]
    measure weight of the infants
  • The effect of intravitreal ranibizumab on height [ Time Frame: corrected age of six month ]
    measure height of the infants
  • The effect of intravitreal ranibizumab on neurologic development [ Time Frame: corrected age of six month ]
    Gesell development diagnosis scale


Original Secondary Outcome: Same as current
