title: Ultrasonographic study on changes in axial eye dimensions after encircling procedure in retinal detachment surgery.
abstract: The pre- and postoperative results of ultrasonographic measurements on the axial ocular components in 10 phakic eyes with retinal detachment treated with encircling silicone rubber band are presented. A significant increase (P less than 0.001) in axial eye length from 0.62 to 1.24 mm (average: 0.98 mm) was found. The elongation of the eye was caused by a corresponding increase in the length of the vitreous cavity. No significant changes were found in the anterior segment of the eyes. These data demonstrate that the postoperative refractive change in a myopic direction, which an encircling procedure with moderate indentation often produces, is caused by an axial elongation of the eye.
