Microphthalmia essentially means small eyes. It is characterised by a small eye within a small orbit. It can be unilateral or bilateral. It is sometimes defined as a globe with a total axial length that is at least two standard deviations below the mean for age.
Microphthalmia can have a complex aetiology and genetics.
Associations
Microphthalmia can either occur isolation in association or with numerous other conditions which include
Antenatal ultrasound
Assessment and detection of microphthalmia antenatally is difficult and is often inferred from a small size of the orbit. There may or may not be evidence of concurrent hypotelorism.
