purpose : to evaluate outcome of surgically slanting extraocular muscle insertions in a and v-pattern strabismus methods : in this prospective non-randomized interventional case series, we created a slanting surgical reinsertion line with a 3- 4 mm difference between upper and lower corners of the muscles in 16 patients with a or v strabismus (v-exotropia in 10 patients, a-exotropia in 1 patien...

PURPOSE The purpose of the present study is to evaluate the therapeutic effects of slanting muscle insertions for "A" and "V" exotropia. METHODS We performed slanting recession and resection of medial or lateral rectus muscles. A slanting surgical incision creating a 3-4 mm difference between the upper and lower margins of the muscles was performed in 28 patients with "A" or "V" exotropia ( "...

BACKGROUND The association of oblique palpebral fissures and A- or V-pattern has not been clarified. We report two cases of A-pattern esotropia with marked mongoloid slanting palpebral fissures associated with vertical displacement of the horizontal rectus muscle. CASES Case 1 was a boy with Prader-Willi syndrome. He showed A-pattern esotropia with upward slanting palpebral fissures. Severe s...

Insertion slanting recessions or biased resections have been reported to be useful for treating A- and V-pattern strabismus, convergence insufficiency, and convergence excess esotropia. Paradoxically, good results have been reported with methods that are opposite in nature. For example, some researchers would recess the medial rectus muscles and slant the superior pole of each muscle back farth...

Implicit Runge-Kutta(IRK) methods for solving the nonsmooth ordinary differential equation (ODE) involve a system of nonsmooth equations. We show superlinear convergence of the slanting Newton method for solving the system of nonsmooth equations. We prove the slanting differentiability and give a slanting function for the involved function. We develop a new code based on the slanting Newton met...

BACKGROUND Sacral slanting is a frequent unique phenomenon in patients with adolescent idiopathic scoliosis (AIS) and may be important for selecting the distal fusion level. However, the reason of the phenomenon remains unknown. The purpose of this study was to determine the association between sacral slanting and adjacent structures in patients with AIS. METHODS A total of 303 AIS patients w...

PURPOSE To describe the spectrum of adnexal and ophthalmologic features in spina bifida. METHODS A retrospective review of the medical records of 73 patients was conducted. Data concerning ocular motility, palpebral fissure orientation, presence and axis of astigmatism, visual acuity, amblyopia, and stereopsis were analyzed. RESULTS Forty-three (59%) of the 73 patients had strabismus: 28 (6...

This paper presents an approach of fusing images from many video cameras or a moving video camera with external orientation data (e.g. GPS and INS data) into a few mosaiced images that preserve 3D information. In both cases, a virtual 2D array of cameras with FOV overlaps is formed to generate the whole coverage of a scene (or an object). We propose a representation that can re-organize the ori...
