The Inferior Rectus
muscle showed minimal fibrosis.
Selective management of double elevator palsy by either inferior rectus
recession and/or knapp type transposition surgery.
- the branch to the inferior oblique also contains parasympathetic preganglionic fibres from the Edinge-Westphal subnucleus
Hypotropia was corrected by inferior rectus
Medial rectus is loosened if the eye is deviated inwards and inferior rectus
if it is deviated downwards.
It bypassed the inferior rectus

Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus
muscles (with Foster suture) was performed.
They innervate superior rectus, inferior rectus
, medial rectus and inferior oblique muscle, and levator palpebrae muscle.
This occurs in order of frequency in the inferior rectus
, medial rectus, superior rectus, lateral rectus, oblique muscles, although most commonly all muscles are involved.
The forced duction test was positive for inferior rectus
(IR) of the involved eye in 20 of the 36 eyes (55.
Early diplopia indicates involve- ment of extraocular muscle either through entrap- ment (usually through inferior rectus
or oblique), oedema, haemorrhage or damage to motor nerves.
The abdominal CT revealed a large organized hematoma, 210x182x142 mm in diameter, in the lower half of the inferior rectus
towards the retroperitoneal area (Fig.
Extensive scarring was encountered, and the inferior rectus
muscle was trapped within the orbital floor defect.
59) observed that BoNT-A administered to the inferior rectus
muscle in cases of adherence syndrome reduced the need for secondary surgery.
