Abstract
Background/aim: Treatment of nystagmus is controversial mainly in cases where it is combined with abnormal head position. This study was carried out to demonstrate that patients with abnormal head position in all three axes associated with nystagmus show improvement in the torsional and vertical components if only horizontal factors are addressed by surgical weakening of the horizontal muscles. Methods: 21 patients with horizontal nystagmus and abnormal head position were studied. All had an abnormal head position in all three axes with a predominant head turn. In all cases a modified Anderson procedure was performed—that is, 2 mm retroequatorial recessions of the horizontal yoke rectus muscles responsible for the blockage position, plus corrective surgery for strabismus when needed. Results: The three components of the abnormal head position were improved with surgery of horizontal yoke rectus muscles only (p=0.001). Conclusion: Large recessions of the horizontal yoke rectus muscles in nystagmus with blockage position, when the head turn predominates over the vertical and torsional components, are effective in diminishing the abnormal head position on all three axes.

Abstract A prospective study was undertaken to analyze the different causes of abnormal head postures on ocular bases. Eight basic mechanisms were found in a series of 188 patients. Incomitance accounted for 62.7% of the head postures and nystagmus for 20.2%. Important diagnostic criteria for evaluating patients with head postures are discussed.

• Nystagmus intensities at various gaze angles were studied both preoperatively and postoperatively, using accurate ocular motility recordings, in three cases of congenital nystagmus. In addition to shifting the nystagmus null, the surgery broadened the null region and resulted in an overall reduction in nystagmus intensity at all gaze angles. Surgical rotation also resulted in improved visual acuity in all cases. The postoperative acuity at 0° was better than the preoperative acuity at both 0° ...

Purpose: To report the results of plication augmentation of the augmented Anderson procedure in patients with infantile nystagmus syndrome and face turn. Methods: In this retrospective study, all patients who underwent plication augmentation of the augmented Anderson procedure between August 2015 and November 2018 were included. Our study included patients older than 6 years with a face turn >25°. We also included patients with residual face turns ≥15° after Anderson-type procedures. The face tu...

Abstract Albinism is a group of rare inherited disorders arising from impairment of melanin biosynthesis. The reduction of melanin synthesis leads to hypopigmentation of the skin and eyes. A wide range of ophthalmic manifestations arise from albinism, including reduction of visual acuity, nystagmus, strabismus, iris translucency, foveal hypoplasia, fundus hypopigmentation, and abnormal decussation of retinal ganglion cell axons at the optic chiasm. Currently, albinism is incurable, and treatment...

PURPOSE: The aim of this study is to evaluate the incidence of consecutive strabismus after infantile nystagmus surgery and its potential risk factors. METHODS: A retrospective study including 89 patients was conducted. Patients presented infantile nystagmus (idiopathic or ocular disease-associated nystagmus) without previous or coincidental strabismus. Sex, age at surgery, amblyopia, botulinum toxin (BT) injection before surgery, spherical equivalent, anisometropia, surgery procedure (Anderson'...

BACKGROUND: The correction of anomalous head posture associated with infantile nystagmus syndrome (INS) is carried out by the Kestenbaum procedure (KP) combining bilateral horizontal yoke muscle recession with resection of their antagonists or by the Anderson procedure (AP) which is confined to yoke muscle recession alone. AIM OF THE STUDY: To compare the results of highly dosed AP and KP for anomalous head turn (HT). PATIENTS AND METHODS: The AP (2013-2019) and KP (2003-2013) were used as the e...

To describe the long-term results of Anderson procedure, which includes recession of the two extraocular yoke muscles responsible for eccentric eye position and abnormal head posture (AHP) in patients with infantile nystagmus. Retrospective data collection of patients who underwent an Anderson procedure at a single medical center by one surgeon from 2008 to 2016. The main outcome measure was the elimination of AHP following surgery. Twenty-seven patients (18 males, 9 females) underwent an Anders...

ABSTRACTPurpose: To report outcomes of vertical extraocular muscle surgery to correct abnormal vertical head posture in children with horizontal infantile nystagmus.Methods: Retrospective case series of seven patients evaluated at one institution with abnormal vertical head position (chin-up or chin-down) in the setting of horizontal infantile nystagmus. All patients underwent bilateral vertical extraocular muscle surgery with the same surgeon. Pre- and postoperative vertical head position under...
