Extraocular muscle involvement in Wegener's granulomatosis.

A 44-year-old man with Wegener's granulomatosis involving the upper and lower respiratory tracts developed a diplopia with involvement of three extraocular muscles of one eye and one extraocular muscle of the other eye. The ocular and orbital examinations were otherwise normal, as were computerized tomography (CT) scans of the brain and orbits. The patient was treated with systemic Cytoxan and Prednisone and the respiratory and extraocular muscle abnormalities cleared within 1 month. Because of the bilateral extraocular muscle involvement, the absence of central nervous system or orbital findings, and the rapid and complete resolution after Cytoxan and Prednisone therapy, a diffuse vasculitis affecting the extraocular muscles was implicated as the etiology of the diplopia.

Anterior segment ischemia syndrome following rectus muscle transposition.

Two patients developed clinically significant anterior segment ischemia following full tendon transposition of the superior and inferior recti muscles nine and 20 years after they underwent horizontal rectus muscle surgery. Ipsilateral carotid artery ligation in one patient and possible hyperlipoproteinemia type II in the other were discovered postoperatively and may have contributed to the circulatory disturbances observed. In adult patients with paretic strabismus, the most important function of the paretic muscle may be maintenance of circulation to the anterior segment of the eye.

A combined surgical approach to bilateral superior oblique palsy.

In two cases of bilateral superior oblique palsy the vertical component of the deviation was more prominent in one eye and the excyclotorsion more prominent in the fellow eye. A tuck of the superior oblique was performed on one eye and an adjustable Harada-Ito procedure on the fellow eye. This combined approach was used to reduce both the torsional and vertical components in these patients with complicated bilateral superior oblique palsies while effecting a more exact resolution of the torsional component.

Congenital rotary nystagmus associated with head turning successful surgical management.

congenital nystagmus is a rhythmic ocular oscillation usually in the horizontal plane which may be associated with a significant head turn, tilt, or tip to achieve maximal damping of eye movements and improved vision. Purely rotary congenital nystagmus associated with head turn is unusual. This report outlines findings in a case of congenital rotary nystagmus with a functionally significant 30-degree head turn and describes successful surgical management. Current management of patients with congenital mystagmus is discussed.

Surgical treatment of congenital nystagmus in patients with singular binocular vision.

Operative treatment of congenital jerk-type nystagmus with ocular torticollis in patients with single binocular vision is discussed. The mechanism causing the head turn as well as the methods used in measuring the head turn and the selection of surgical procedures to correct it are analyzed. The results of 7 cases operated upon for this condition are presented.

The management of hemangiomas of the eyelid and orbit.

The growth of hemangiomas of the orbital region varies greatly; it is unpredictable. Most lesions never reach sufficient size to impair vision; a few, however, may grow sufficiently to cause disastrous complications. Nine children with complete or partial occlusion of the vision by hemangioma of one eye are reported. (Functional vision was preserved only in those patients who had early subtotal excision of the eyelid hemangioma.) Two children with complete occlusion developed amblyopia in the involved eye. One had optic nerve atrophy. One of the four children with partial occlusion of vision had a permanent decrease in visual acuity. Of the remaining three children with normal vision, two had been operatively treated early, and one had unusually rapid involution of the hemangioma. We recommend that when a child has complete or partial visual occlusion due to hemangioma, subtotal or total excision of the hemangioma should be carried out within 1 week of the onset of visual occlusion to prevent amblyopia.

Congenital absence of lateral rectus muscle.

A four-year-old female presented with a 60 PD left esotropia and Axenfeld's anomaly OU. Cosmetic strabismus surgery was undertaken, at which time it was discovered that the left lateral rectus was absent. The medial rectus was recessed, without change in the esotropia. At a second procedure six months later, the superior and inferior rectus muscles were transposed to the area of the missing lateral rectus. Follow-up examination revealed an 8 PD left esotropia with full ductions.
