Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones.Osteogenesis imperfecta type 1 is the mildest form of OI and is characterized by bone fractures during childhood and adolescence that often result from minor trauma. Fractures occur less frequently in adulthood. People with mild forms of the condition typically have a blue or grey tint to the part of the ...

Blue sclerae, especially at infancy, is the most visible ocular sign in osteogenesis imperfecta but it is not always present. It is also often present in normal infants. In some patients, it is present early but disappears later in life. Some patients have significantly lower ocular rigidity, corneal diameters, and decreased globe length.

Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones. The term "osteogenesis imperfecta" means imperfect bone formation.People with this condition have bones that break easily, often from mild trauma or with no apparent cause. Multiple fractures are common, and in severe cases, can occur even before birth.
