The phenomenon of reversal of glaucomatous cupping of the optic disc following lowering of the intraocular pressure (IOP) was originally recognized in infants. We evaluated the change in optic disc cupping with normalization of the IOP after trabeculotomy in primary congenital glaucoma and assessed the factors associated with reversal of cupping. ⋯ Optic disc cupping can be reversed at an early stage of primary congenital glaucoma following successful reduction of IOP. Younger age at surgery was associated with reversal of cupping.
