Abstract

BACKGROUND:

The "Early Treatment for Retinopathy of Prematurity Cooperative" reported a failure rate of 55.2% using laser in zone 1 for treatment of retinopathy of prematurity (ROP). We need to offer better alternatives for those patients. We undertook this study to evaluate the efficacy of combined laser-ranibizumab therapy for ROP with threshold-prethreshold and "plus disease" and to study development of the newborn.

METHODS:

This is a prospective, experimental, longitudinal and open study including newborns of either <32 weeks of gestation or with a birth weight <1500 g, with threshold-prethreshold retinopathy or "plus disease." The effect of treatment was analyzed and development of the newborn was determined.

RESULTS:

We studied 34 eyes of 17 patients. Age at birth was 29.9 ± 2.6 weeks. Birth weight was 1,120 ± 253 g. The statistics demonstrated an important relationship between severity of retinopathy and early birth age, along with a high probability of threshold-prethreshold disease at 29.4 weeks of age or 1204 g birth weight. The Bayley scale reported normal development in 23.5% of cases, global retardation in 23.5%, psychomotor retardation but normal mental behavior in 29.4%, and mental retardation but normal psychomotor development in 23.5%. We demonstrated regression of retinopathy in all cases. Persistence of vascular tortuosity was present in 17.6% of cases without vascular dilatation, and vitreous membrane development was demonstrated in 11.7% of patients.

CONCLUSIONS:

Laser-ranibizumab treatment has allowed a better control of retinopathy for threshold-prethreshold and "plus disease" in this group of patients.
