Periorbital cellulitis in infancy.

To our knowledge, no previous study of periorbital cellulitis has focused on its specific characteristics in infants only (less than 1 year of age.) We retrospectively studied 30 cases of infantile periorbital cellulitis treated at Harbor-UCLA Medical Center from 1977 to 1988. Characteristics of the disorder in our infants older than 1 month were similar to earlier reports of older children in terms of etiology, radiological and bacteriological findings, and course. However, compared with our older infants, our seven neonates (7 to 30 days old) had a higher incidence of ruptured dacryocele (29% vs 0%) and unknown source of the infection (43% vs 4%); but a lower incidence of preceding upper respiratory infection (14% vs 78%), abnormal sinus films (0% vs 22%), and positive blood cultures (14% vs 30%). Of the positive cultures, Hemophilus sp was the most common pathogen among the older infants (35%), while Streptococcus and Staphylococcus were the most frequent among the neonates (71%). All infections remained preseptal and responded well to intravenous antibiotics.

Vertical rectus muscle transposition surgery for Duane's syndrome.

Thirteen patients with Duane's syndrome, Type I, underwent full vertical rectus muscle transposition. Prior to surgery, all patients had esotropia in the primary position and 11 patients had a face turn. Postoperatively, esotropia was improved in 77%. The face turn was improved in 100% and eliminated in 69%. Abduction ability was increased and binocular diplopia-free field size enlarged to a mean of 60 degrees. Seven patients (54%) with a mean preoperative deviation of 17 prism diopters required only vertical rectus muscle transposition to improve their face turn and strabismus. Six patients (46%) with a mean preoperative deviation of 30 delta required an additional medial rectus recession several months later. Two patients (15%) developed a vertical deviation following vertical rectus muscle transposition.

Clinical characteristics and surgical treatment of intermittent esotropia.

This study describes the age of onset, symptomatology, and clinical characteristics of 25 patients with intermittent esotropia. This subgroup of esotropic patients typically has onset prior to 10 years of age and shows excellent bifoveal fixation ability, reflected by a high degree of stereopsis. In contrast to patients with other forms of esotropia, there is minimal to no hyperopia, an average esodeviation of approximately 20 prism diopters, and a low incidence of amblyopia, DVD, and oblique overaction. Symptomatic diplopia or cosmetic concern necessitated surgical intervention in 17 (68%) patients. Fifteen (88%) patients had good or excellent surgical results of either orthophoria, esophoria, or residual esotropia of 10 delta or less. One patient (6%) had residual esophoria greater than 10 delta. One patient had 4 delta of exophoria postoperatively. Intermittent esotropia should be differentiated from the various entities of microtropia, fixation disparity, and monofixation syndrome.

Periorbital cellulitis in infancy.

To our knowledge, no previous study of periorbital cellulitis has focused on its specific characteristics found only in infants (less than 1 year of age.)
