PURPOSE To evaluate the correction of hypertropia in primary position with unilateral inferior oblique (IO) anterior transposition (IOAT). METHODS Ten patients with idiopathic (nonparalytic, restrictive, or dissociated vertical deviation) hypertropia with marked IO overaction, who underwent unilateral IOAT, were prospectively evaluated to observe the correction of the hypertropia in primary p...

BACKGROUND This is a retrospective study to determine the outcomes of the surgical correction in long-standing infantile esotropia with cross fixation. METHODS Medical charts of a group of patients with esotropia who had cross fixation and underwent surgery for strabismus between January 1991 and December 2004 were reviewed. The mean follow-up time was 4.7 years. Binocularity was measured by ...

A 51-year old man presented with vertical and torsional diplopia after reduction of a blowout fracture at another hospital one year ago. He had no anormalies of head position and 14 prism diopters (PD) right hypertropia (RHT) in the primary position. In upgaze no vertical deviation was found, and hyperdeviation on downgaze was 35PD. Bielschowsky head tilt test showed a negative response. Distin...

The results of squint surgery in 40 children with congenital esotropia are analysed. A 'favourable outcome' was achieved in 23 (57.5%) children. The factors affecting the final outcome including ocular alignment in the immediate postoperative period, age at the time of surgery, amblyopia, associated inferior oblique overaction, dissociated vertical deviation, latent or manifest latent nystagmus...

PURPOSE In ocular kinematics, the primary position (PP) of the eye is defined by the position from which movements do not induce ocular rotations around the line of sight (Helmholtz). PP is mathematically linked to the orientation of Listing's plane. This study was conducted to determine whether PP is affected differently in patients with clinically diagnosed congenital (conTNP) and acquired (a...

PURPOSE To evaluate the surgical results of medial rectus (MR) muscle advancement with or without recession of the antagonist muscle for consecutive exotropia. METHODS Medical records of patients with consecutive exotropia (n = 27) were retrospectively reviewed. All patients received one-eye surgery with MR advancement, lateral rectus (LR) recession, or combined surgery. The pre- and post-ope...
