Sclera — The part of the eye around the colored pupil commonly referred to as "the whites of the eyes." Some, not all, people with OI appear to have a blue, purple or gray tint to their sclera. The color may range from barely noticeable to very dark and may change with age.

Sclera: The white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. It is essentially avascular but contains apertures for vessels, lymphatics, and nerves. It receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the canal of Schlemm. (From Cline et al., Dictionary of Visual Science, 4th ed)2
