Dear user Foveal hypoplasia is a congenital disease characterized by poor development of fovea, the most visually sensitive part of the retina. It is known to be associated with many other ocular anomalies like nystagmus, microphthalmos, aniriidia..... I think your daughter has got only nystagmus as associated condition as from the history. This is good prognostic sign. But as of know there is noknown effective treatment for foveal hypoplasia. Few treatments are still in research stage like retinal transplantation, retinal chip implants... I hope that these treatments may become successful in near future which becomes new hope of light to so many patients with congenital anomalies of retina. Thank you
