Facial nerve palsy, whether the cause is idiopathic, or following such insults as surgery, trauma, or malignancy, places the health of the ocular surface at risk. Reduced or absent orbicularis oculi function results in lagophthalmos and exposure of the cornea, which is exacerbated by eyelid malposition. Management of the exposure keratopathy is paramount to prevent corneal breakdown, scarring, ...

The effects of fourth nerve palsy on the vestibulo-ocular reflex (VOR) had not been systematically investigated. We used the magnetic scleral search coil technique to study the VOR in patients with unilateral fourth nerve palsy during sinusoidal head rotations in yaw, pitch and roll at different frequencies. In darkness, VOR gains are reduced during incyclotorsion, depression and abduction of t...

Aims. To report the results of lateral rectus muscle recession, medial rectus muscle resection, and superior oblique muscle transposition in the restoration and maintenance of ocular alignment in primary position for patients with total third-nerve palsy. Methods. The medical records of patients who underwent surgery between March 2007 and September 2011 for total third-nerve palsy were reviewe...

purpose: to report the outcomes of surgical and non-surgical treatment for sixth nerve palsy and paresis in our center. methods: hospital records of 33 patients (35 eyes) with sixth nerve dysfunction who were referred to labbafinejad medical center from september 1996 to september 2006 and underwent surgical procedures or botulinum toxin injection were reviewed. results: patients were divided i...

purpose: to evaluate the results of augmented vertical rectus muscle transposition with intraoperative botulinum toxin for complete and chronic sixth nerve palsy. methods: during a 10 years period (1381-1390) all patients with chronic and complete sixth nerve palsy, and contracted medial rectus (mr) underwent augmented vertical rectus muscle transposition with botulimum toxin injection into the...

Twenty-seven patients with unilateral sixth nerve palsy and ten normal subjects were studied. The range of ductions was examined and the degree of abduction defect was recorded. The amount of horizontal and vertical deviations was measured in nine diagnostic positions by the prism and cover test, Maddox rod and prism test, and magnetic scleral search coils. MRI with enhancement was performed fo...
