Case report.

66-year-old woman with one eye amblyopic and no history of injury, reported loosing visual acuity in the last two years. She was studied with specular microscopy, slit lamp examination, indirect ophthalmoscopy, anterior and posterior segment optical coherence tomography, corneal tomography and gonioscopy. According to the findings different diagnosis were considered, including Peters' anomaly and corneal dystrophy.

Posterior keratoconus (or keratoconus posticus), first described in 1930 by Butler, is sporadic, usually nonprogressive corneal disease, but it also depends on associated ocular anomalies.
