Brief Summary:
Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Vascular endothelium growth factor (VEGF) is an important component of this disease. The goal of treatment is to reduce the production of VEGF in the immature retina and to eliminate the abnormal growth of new vessels. Currently, laser photocoagulation of the peripheral avascular retina is the treatment standard. Intravitreal injection of anti-VEGF antibody Bevacizumab (IVB) has been used clinically off-label as an alternative therapy. However, VEGF is important for the development of neurons and vessels in the systemic organs in premature infants. Pharmaceutical study showed that IVB was absorbed into the bloodstream. It is unclear if the systemic absorption of Bevacizumab is dose related, and the short and longterm effects on ocular and systemic systems, especially neurological development. In this study, our goals are to establish the pharmacokinetics of Bevacizumab in the premature infant and to compare the short and long-term vision and neurodevelopmental outcomes of infants treated with IVB compared to laser ROP.

Condition or disease
Focus of the Study is to Evaluate the Efficacy and Safety of Bevacizumab for the Treatment of ROP

Detailed Description:
This study will enroll preterm infants who were scheduled to receive treatment for ROP by laser or Bevacizumab. We will observe the patients in the hospital for the cure of ROP until 54 weeks' postmenstrual age. We will check the changes of chemicals in the blood and observe short-term and long-term effects on visual system, brain and other body organs. Descriptive statistics from a two sample t-test or Fisher's exact test will be used to compare the short and long-term vision and neurological development outcomes. We predefined a statistical significance level p=0.05.

Primary Outcome Measures :
  1. Vision [ Time Frame: 5 years ]
    Visual acuity will be measured at age of 3 and 5 years with HOTV card.

Secondary Outcome Measures :
  1. The changes of neurodevelopment outcome from birth to 5 years of age [ Time Frame: 1 to 5 years old ]
    Neurodevelopmental assessments will be performed by board-certified, developmental-behavioral pediatric and neurodevelopmental disability pediatricians. Each neurodevelopmental assessment includes a developmental history, direct behavioral observations, and direct developmental testing using the Revised Gesell Developmental Schedules; the Motor Quotient will be used to assess gross motor development; and the Capute Scales will be used used to assess non-verbal, visual-motor problem-solving development and speech and language development.
