[Characteristics of retinal detachment in children]

Pediatric retinal detachments differ from adult retinal detachments in their etiologies, prognosis and treatment. The aims of this study were the analysis and long-term follow-up of a group of pediatric retinal detachment patients.

All the cases of juvenile retinal detachments treated in our department between 1987 and 1999 were retrospectively studied. The age at the time of diagnosis, etiology, initial topography of the detachment, treatments undertaken, follow-up, and final results were recorded.

The study investigated 64 eyes of 53 children. The follow-up was longer than 6 months for 31 eyes, with a mean follow-up of 39.5 months. The main etiologies were traumatism, high myopia, and affections leading to an exudative retinal detachment such as retinoblastoma and Coats disease. Circular scleral buckling was often used because of the vitreous cohesiveness in children. A vitrectomy was frequently associated to treat severe proliferative vitreoretinopathy. The final visual acuity was higher than 0.05 in 32% of the cases.

The etiological features, late diagnosis and frequency of proliferative vitreoretinopathy are responsible for the greater severity of retinal detachments in children. These factors associated with amblyopia lead to poor visual prognosis.

Retinal detachment in children remains a severe pathology. However the prognosis seems to be improving with progress in examination techniques and surgery methods.
