About

The aim of the present study is to evaluate the safety and efficacy of propranolol eye drops in preterm newborns with a precocious stage of retinopathy of prematurity (ROP). Preterm newborns (gestational age 23-32 weeks) with a stage 2 ROP (zone II without plus) will receive propranolol eye drops treatment until retinal vascularization will be completed.

Propranolol concentrations will be measured on dried blood spots during the first 3 days of treatment and at the steady state. Cardiovascular and respiratory parameters will be continuously monitored. Blood samplings checking metabolic, renal and liver functions will be performed periodically, as well as cardiac function, in order to verify the treatment safety. Serial ophthalmological evaluations will be planned to monitor the efficacy of the treatment, the ROP progression and the possible complications.

Propranolol eye drops
Experimental group
Description:
All the enrolled preterm newborns will receive propranolol as ophthalmic solution (0,1%): 3 microdrops of 6 microliters (μL) propranolol solution (= 6 μg propranolol/microdrop) will be topically applied with a calibrated pipette, in each eye, three times daily (every 8 hours).The treatment will continue until the complete development of retinal vascularization, but no more than 60 days. The propranolol treatment will be always associated to the conventional approach adopted by the Early Treatment for Retinopathy of Prematurity Study (ETROP Cooperative Group.
Treatment:
Drug: Propranolol eye drops
