Objectives: To present the outcomes of unilateral inferior oblique myectomy performed in patients with inferior oblique overaction due to superior oblique palsy.

Materials And Methods: Twenty-seven eyes of 27 patients that underwent inferior oblique myectomy surgery for superior oblique palsy between 2002 and 2008 were included. Inferior oblique overaction scores (between 0-4) at preoperative, early postoperative (within 1 week after surgery) and late postoperative (earliest 6 months) visits were reviewed.

Results: There were 12 male and 15 female patients. Eighteen were operated on the right eye, and 9 were operated on the left eye. The mean age was 15.62±13.31 years, and the mean follow-up was 17±11.28 months (range, 6-60 months). Patients who had horizontal component and V-pattern deviation were excluded. Preoperative and early postoperative inferior oblique overaction scores were 2.55±0.75 and 0.14±0.36, respectively, and the difference was statistically significant (p<0.01). This improvement was maintained up to the late postoperative period.

Conclusion: Due to its promising short-term and long-term results, inferior oblique myectomy can be the first choice of surgery for inferior oblique overaction due to superior oblique palsy.

Duane retraction syndrome (DRS) is complicated to treat due to its wide spectrum of clinical presentations and the treatment of choice varies among surgeons. To provide insight into this challenging condition, we evaluated the long-term surgical outcomes of esotropic DRS type 1. The surgical motor success, defined as a horizontal deviation of 8 prism diopters (PD) or less, was found in 77.

The purpose of this study is to evaluate the effectiveness of intensity-modulated radiation therapy (IMRT) combined with periorbital triamcinolone acetonide injection in treating thyroid eye disease (TED) patients with active extraocular muscle but low CAS. The retrospective observational study was conducted. A total of 156 eligible patients were selected from the TED patient database of the Ophthalmology Department of West China Hospital of Sichuan University.

Background: Involution or aging is the most common cause of lower eyelid entropion (in-turning of eyelid margin) in the elderly population. Various pathomechanisms have been postulated for its occurrence. Aging leads to laxity of tissues and loss of muscle tone.

Plaque brachytherapy has been used in the management of small to medium-sized choroidal melanomas for the past few decades. As the inferior oblique muscle lies in close relation to the macula, the placement procedure of plaques often involves sacrificing the inferior oblique muscle, especially in cases of macular or perimacular choroidal melanomas. In this study, we have described a simple maneuver to preserve the inferior oblique muscle.
