“…Two of the nine patients (22%) who received botulinum toxin injections in addition to VRT achieved a successful outcome, whereas six of the 14 patients (43%) who did not receive botulinum toxin injections achieved a successful outcome (p = 0.31). For the patients who underwent a Hummelsheim-type procedure, five patients underwent augmented Hummelsheim procedures with combined medial rectus muscle recession as previously described, 15 whereas four patients underwent Hummelsheim procedures with posterior fixation sutures as previously described 16 without simultaneous combined medical rectus muscle recession. Patients who underwent a Hummelsheim procedure had a higher rate of success compared with patients who underwent a VRT (p = 0.049; Table 2).…”

Abducens nerve palsy is the most common acquired ocular motor nerve palsy in adults. Chronic cases of abducens palsy often require surgical intervention to relieve disabling diplopia. The goal of this study was to identify factors associated with surgical outcomes in isolated abducens palsy. Medical records of all adult patients from 1988 to 2012 with abducens palsies who underwent strabismus procedures were retrospectively reviewed. Motor alignment, extraocular motility, and sensory outcomes were recorded. Success was defined as absence of diplopia without prisms or face turn, vertical deviation 2 prism dioptres (PD), and horizontal deviation 10 PD. Eighty-one patients (age range: 20-86 years) met inclusion criteria. Success was achieved in 58% of patients. Final success rates for abducens palsy were 50% for neoplastic, 59% traumatic, 57% for microvascular/unknown, and 67% for other central nervous system causes (p40.05). Patients with an underlying neoplastic or traumatic aetiology required more than one strabismus procedure more often than those with microvascular/idiopathic or other central nervous system causes (48% vs. 24%; p = 0.03). For complete abducens palsies, patients who underwent Hummelsheim-type procedures had a higher success rate than those who underwent a full-tendon vertical rectus muscle transposition. (78% versus 35%; p = 0.049). Success rates for strabismus procedures in patients with abducens palsies are similar across all aetiologies. Frequency of re-operation is higher among those patients with neoplastic or traumatic aetiologies for their abducens palsies. Hummelsheim-type procedures have a higher success rate for complete abducens palsies than full-tendon vertical rectus transpositions.

“…[3][4][5][6][14][15][16][17] Both approaches avoid recession of the ipsilateral medial rectus, thus decreasing the risk of anterior segment ischemia, and at the same time leaving this muscle unaffected and fully capable of adducting the eye. Both approaches may induce undesired vertical deviation, which is probably secondary to the vertical muscle transposition rather than the botulinum toxin injection.…”

“…[4][5][6] The goals of surgery are to correct horizontal deviation in the primary position, eliminate anomalous head posture, increase the degree of abduction, and enlarge the field of binocular vision. [6][7][8][9][10][11] Pressman and Scott 8 reported success in a small series of patients with bilateral Duane syndrome by using medial rectus recessions for the correction of esotropia. They reported outcomes of unilateral or bilateral muscle recession in 19 patients with Duane syndrome, of whom 5 patients had a bilateral type 1 esotropic Duane syndrome.…”
