Brown’s syndrome is a condition which can be present from birth or develop later on in life. Around our eye there are 6 eyes muscles which control which direction our eyes moves in. In Browns syndrome one of the muscles, called the Superior Oblique, is affected. The superior oblique turns our eye inwards and upwards.
The Superior Oblique passes through a ring of cartilage called the Trochlea, which acts as a natural “pulley” system in helping the eye to move. In Brown’s syndrome, there is a defect to the trochlea, or, to the muscle itself. This stops the muscle from passing through the Trochlea, thus, inhibiting the eye to look up and inwards.
