ABSTRACT

A 47-year-old "Mexican mestizo" male who had 4-years past ocular history of insidious and painless visual loss, night blindness and progressive constriction of bilateral peripheral visual fields. The patient had a previous diagnosis of bilateral keratoconus and underwent a corneal transplantation in the right eye in 1986 because of hydrops sequel. Visual capacity with hard contact lens was counting fingers right eye and 20/100 left eye. Biomicroscopy right eye findings were clear corneal graft, posterior subcapsular lens opacity and clinical signs of keratoconus with a clear lens in the left eye. Fundus examination revealed symmetric findings: pigment in vitreous, optic disc pallor, attenuated retinal vessels, mottling and granularity of the retinal pigment epithelium, and bone-spicule intraretinal pigmentation. Visual field examination and electroretinogram were strongly altered bilaterally.
