Hyperplastic persistence of the pupillary membrane is a rare but devastating congenital anomaly. Extensive and thick membrane arised from the collarette of iris covering the whole or most of the pupil and sometimes adhering to the anterior surface of the lens forming anterior capsular cataract. Victims of this anomaly often suffered from clinical significant intractable organic amblyopia. Few early medical or surgical management to prevent visual disturbance wore reported in the literature(1,2,3,4). However, only certain cases with less extensive persistent pupillary membrane and at least pupillary aperture of 1.5mm in diameter could achieve successful medical treatment by mydriatics and occlusion therapy(2). Available surgical methods such as sector iridectomy & coreoplasty(1) are often complicated with severe iritis, hyphema and cataract. Using the Nd-YAG laser as a new therapeutic tool, we have successfully treated 7 patients of persistent pupillary membrane. The detached membranes were easily removed from pupillary margin with only Limited complications.
