Further study details as provided by Smith-Kettlewell Eye Research Institute:

Primary Outcome Measures:
  • development of apnea and or bradycardia [ Time Frame: 3 weeks ]
    babies were monitored and HR/RR monitored and recorded by masked observers, periodically

Secondary Outcome Measures:
  • development of ROP requiring treatment [ Time Frame: 7 weeks ]
    Type I ROP was used as a secondary outcome measure

Enrollment: 23
Study Start Date: April 2011
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

masked labeling also 2 per day administration
Drug: topical betaxolol
given topically

Detailed Description:
The drug is administered twice a day between 32 and 35 weeks gestational age, at a t ime when ROP is most likely to arise.
