Abstract. Purpose:To report a case of Leber's congenital amaurosis(LCA)who developed keratoconus and acute hydrokeratoconus. Case:A 16-year-old male presented with sudden visual loss in his left eye. He had nystagmus at the age of 4 months. Electroretinogram(ERG)was nonrecordable,leading to the diagnosis of LCA. Keratoconus developed in both eyes at the age of 12 years. His corrected visual acuity was 0.03 right and 0.04 left at the age of 15 years. Pattern visually evoked cortical potential(VECP)was nonrecordable for both eyes. Findings:Left visual acuity was hand motion. Acute hydrokeratoconus was present in the left cornea. Corneal edema subsided 3 weeks later leaving scarring and opacity. Eight months after the episode,keratoplasty is under consideration as treatment. Conclusion:LCA may be associated with keratoconus. This case is unusual because of rapidity of acute hydrokeratoconus.
