Abstract:
In a 69-year-old man with ochronosis, circumscribed brown-black scleral spots with injection of conjunctival vessels and some small pigmentations of the peripheral superficial cornea occurred. Ochronosis is an autosomal recessive chronic disease, whereby early detection of cardiac valvular defects and arthritis is important particularly in patients who are older than 40 years.
