    Abstract:
    BACKGROUND: Technical advances in neonatal intensive care have significantly increased the number of very low birth-weight babies that survive the perinatal period. Some of these infants develop severe retinopathy of prematurity that may lead to retinal detachment. METHODS: Between November 1988 and January 1994, 28 eyes from 15 preterm babies underwent scleral buckling for stage 4 retinopathy of prematurity at a mean age of 4.2 months. Cryotherapy was performed preoperatively on 12 eyes and intraoperatively in the remaining 16 eyes. The mean follow-up period was 35 months. RESULTS: Scleral buckling produced retinal reattachment in 13 eyes (46.4%). Severe myopia (-5 D to -15 D) was found in all 13 of these eyes, 12 also presented convergent strabismus. Mean visual acuity, measured in 6 eyes from children over the age of 3 years was 20/40. In 7/28 eyes of the younger children of this group we found a fix and follow the light capability. No light perception was detected in 11/28 eyes; in the remaining 4/28 eyes there was only light perception. Scleral buckling failed to prevent the progression to stage 5 in 15 eyes (53.6%). Additional surgery was excluded for 9 of these eyes based on ultrasonography findings; the other 6 eyes underwent vitrectomy, which led to macular reattachment in 4 cases. CONCLUSIONS: Clinical experience shows that scleral buckling is not always capable of preventing progression of the disease to stage 5. Furthermore, even when the anatomic results of this procedure are good, the functional outcome is often complicated by severe visual impairment.
