connective tissue disorder that mainly affects the eyes, joints and skin. Signs and symptoms may include rupture of the cornea after only minor trauma; degeneration of the cornea (keratoconus) or thinning and protrusion of the cornea (keratoglobus); bluish tint in the white part of the eyes (blue sclerae); hypermobile joints; hyperelastic skin; hearing defects; and dental abnormalities. There are 2 types of BCS which are distinguished by the mutated gene that causes the condition.
