Objective: To evaluate the effects of different surgical methods and postoperative eye positions on the quality of life of children with intermittent exotropia (IXT) and their parents 3 months following strabismus surgery. Methods: Clinical observation. One-hundred and eighty children aged 2 to 17 years with IXT who received surgical treatment were recruited. One parent of each child was investigated by using 2 kinds of the Chinese version of the Intermittent Exotropia Questionnaires (CIXTQ) within 1 weeks before and at 3 months after surgery: the parent proxy scale (for parents to assess children's health related quality of life (HRQoL)) and the parent scale (containing functional, psychosocial and surgery subscales; for parents to assess their HRQoL)...

Septoplasty is a commonly used procedure for correcting septal cartilage deformities. Hemorrhage, abscesses, scaling, adhesions, and scar tissue are often seen after the operation of the septoplasty, but temporary or permanent visual loss due to local anesthetic use has been reported very rarely in the literature. The authors also aimed to present a female patient with retinal artery spasm in the right eye after septoplasty in this article. A 27-year-old female patient was admitted to the authors' clinic with long-standing nasal obstruction and postnasal drip...

REVIEW
Ramesh Kekunnaya, Mithila Negalur
Duane retraction syndrome (DRS) is a congenital eye movement anomaly characterized by variable horizontal duction deficits, with narrowing of the palpebral fissure and globe retraction on attempted adduction, occasionally accompanied by upshoot or down-shoot. The etiopathogenesis of this condition can be explained by a spectrum of mechanical, innervational, neurologic and genetic abnormalities occurring independently or which influence each other giving rise to patterns of clinical presentations along with a complex set of ocular and systemic anomalies...

In subjects with alternating strabismus either eye can be used to saccade to visual targets. The brain must calculate the correct vector for each saccade, which will depend on the eye chosen to make it. The superior colliculus, a major midbrain center for saccade generation, was examined to determine if the maps serving each eye were shifted to compensate for strabismus.Alternating exotropia was induced in two male macaques at age one month by sectioning the tendons of the medial recti. Once the animals grew to maturity, they were trained to fixate targets with either eye...
