PURPOSE: We report a patient with abnormal head posture following ocular blunt trauma. METHODS: This is report of a case that despite findings compatible with diagnosis of left superior oblique (SO) palsy, the patient acquired an ipsilateral (left) head tilt. The interesting observation in our patient was reduction of left hypertropia and consequent less diplopia with ipsilateral head tilt. RESULTS: After blunt trauma, our patient adopted paradoxical left head tilt and consequently less diplopia despite acquired left SO palsy...

Dong Cheol Lee, Se Youp Lee
BACKGROUND: Several inferior oblique (IO) weakening methods exist for correction of superior oblique palsy (SOP). A previously reported method involved recession and anteriorization according to IO overaction (IOOA) grade, which might be subjective and cause upgaze limitation and opposite vertical strabismus. Therefore, this study attempted to examine the efficacy of modified graded recession and anteriorization of the IO muscle in correction of unilateral SOP without resulting in upgaze limitation or opposite vertical strabismus...

INTRODUCTION AND PURPOSE: We describe the clinical characteristics of 252 patients with unilateral superior oblique palsy who underwent strabismus surgery. We assess if a predetermined surgical strategy, based on preoperative alignment and motility measurements, was effective in treating these patients. On this basis, the patients were divided into three different treatment groups. METHODS: Two-hundred fifty-two patients were identified retrospectively and classified into three groups according to the performed procedures: 1) inferior oblique weakening; 2) inferior rectus recession; 3) combined inferior oblique weakening and inferior rectus recession...

Yair Ivanir, Jonathan D Trobe
BACKGROUND: Isolated fourth nerve palsies are commonly caused by decompensation of a congenitally dysfunctional superior oblique muscle ("decompensated congenital palsies"). Distinguishing such palsies at initial presentation from palsies caused by presumed microvascular ischemia ("ischemic palsies") has value for patient reassurance and in forestalling ancillary testing. Abnormally large vertical fusional amplitudes traditionally have been used to identify decompensated congenital palsies, but that may not be a reliable distinguishing feature...

The purpose of this study was to determine the effect of unilateral fronto-orbital advancement (FOA) or bilateral FOA on ocular aspects of plagiocephaly. A retrospective review of ocular findings in 16 patients with plagiocephaly was performed. Patients were divided into 2 groups: 12 patients who underwent bilateral FOA (bFOA) and 4 patients who underwent unilateral FOA (uFOA), and ocular findings were compared. One-half of patients showed strabismus in both groups, and all had exotropia. Hypertropia was found only on the same side of the plagiocephaly in 17% of the bFOA group and 25% of the uFOA group...
