Juvenile retinal detachment.

The features and prognoses of 802 cases (908 eyes) of retinal detachment from 8 months to 19 years of age were studied with the patients divided into three age groups: 65 eyes in group I (0-9), 259 eyes in group II (10-14), and 584 eyes in group III (15-19). Eyes in group I were different from the others in many respects. In group I, traumatic detachments, preoperative complications, four-quadrant detachments, and eyes with undetected breaks were more frequent, and the prognosis was worse than in the other groups. Holes with lattice degenerations were most frequent in group III eyes having no history of trauma. Group III resembled adult retinal detachment and group II was thought to be the transitional type.
