PURPOSE: Papillorenal syndrome is an autosomal dominant entity due to PAX2 gene mutation, involving optic nerve and renal malformations. METHODS: The authors report a 19-year-old man with bilateral macular detachment associated with optic nerve pit in one eye and morning glory syndrome in the other eye. The patient underwent three-port pars plana vitrectomy, endolaser photocoagulation, and C3F8 gas tamponade in his best eye. A medical history of vesicoureteric reflux and kidney hypoplasia led to genetic analysis. RESULTS: Molecular genetic PAX2 analysis revealed a novel nondescribed mutation in exon 3. One year postoperatively, ophthalmologic outcomes were satisfactory with complete flattening of the retina and improvement of the best-corrected visual acuity to 11/10. CONCLUSIONS: PAX2 is involved in the optic vesicles, genital tracts, kidney, and central nervous system embryogenic development. The association of optic nerve and renal malformations should lead to the suspicion of papillorenal syndrome with PAX2 mutation.
