This paper presents a comparative study of the effectiveness of myectomy and anterior transposition in the treatment of inferior oblique muscle overaction. We operated 160 patients with overaction of the inferior oblique muscle. Eighty patients (148 eyes) were operated by myectomy at the insertion and 80 patients (151 eyes) by anterior transposition of the insertion of the inferior oblique near the temporal side of the insertion of the inferior rectus muscle. Comparison of the two methods, using the chi-squared test, showed that: 1) both surgical procedures were equally effective (χ2=0.26) for correcting overaction of the inferior oblique muscle and V-phenomenon; 2) weakening of the inferior oblique muscle of both eyes was almost always required (in 115 out of 116 cases) in cases with V-phenomenon and often (24 out of 44 cases) in cases of congenital paresis of the superior oblique muscle. We conclude that both procedures are equally effective and equally easy to perform.

Purpose: To evaluate the efficacy of early neuroimaging in patients with acute isolated 3rd, 4th, and 6th nerve palsy.Methods: Neuroimaging tests were performed in patients >50 years old with acute isolated 3rd, 4th, and 6th nerve palsy. The frequencies and types of abnormal findings were evaluated. All patients were divided into ischemic and non-ischemic groups and differences in clinical characteristics between groups were analyzed.Results: Of the 55 patients, nine (16.4%) had abnormal findings on brain imaging. Among 26 patients with 6th nerve palsy, four (15.4%) were found to have a cause including brain tumor, cerebrovascular compression, carotid cavernous fistula. Superior oblique muscle atrophy was found in two of 19 patients (10.5%) with 4th nerve palsy. Three of 10 patients (30%) with 3rd nerve palsy had abnormal findings and there were cases of pituitary apoplexy, posterior communicating, and cerebrovascular compression.Conclusions: In patients with acute isolated oculomotor paralysis, early neuroimaging tests play an important role in differential diagnosis and evaluation of causes that may lead to mortality.
