PURPOSE: To report the effect of the abnormal head posture (AHP) correcting procedures on the visual acuity improvement in patients with infantile nystagmus syndrome (INS) and the visual acuity improvement outcomes in different AHP correcting surgeries in INS. METHODS: This was a prospective, non-randomized, interventional study. Twenty-eight patients underwent the Anderson-Kestenbaum procedure or the modified Anderson procedure with or without tenotomy of at least one horizontal recti for corre...

Purpose: To evaluate the efficacy of the augmented Anderson procedure in idiopathic infantile nystagmus (IIN). Methods: Twelve consecutive patients older than 5 years having IIN with eccentric null position and anomalous head position were enrolled in an institution-based study. Best-corrected visual acuity (uniocular and binocular and in both null position and primary position), slit-lamp examination, fundus examination, ocular motility examination, and stereopsis using TNO were recorded. In al...

Purpose The purpose of this report is to characterize the clinical and electrophysiological effects of extraocular muscle surgery in 15 patients with oculo-cutaneous albinism (OCA) and infantile nystagmus syndrome (INS). Our hypothesis is that surgery on the extraocular muscles of patients with OCA and INS changes their nystagmus and their visual function. Design Interventional, prospective, cohort, noncomparative case series. Methods All 15 patients had surgery on all four virgin horizontal rec...

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 abn...

Abstract Ten patients had large recession of four horizontal recti at one procedure for treatment of nystagmus. Six patients had congenital motor nystagmus, two had oculocutaneous albinism, and two had optic nerve hypoplasia. Anomalous head posture with null point was also present in five patients. The rectus muscles were placed at or behind the equator in all but one case. Three patients with both esotropia and nystagmus had the medial recti placed 1 mm behind the equator and the lateral recti ...

: The author reports the long-term (average 11 years) results of surgery to correct the face turn or tilt adopted to use the null zone associated with nystagmus. Of the 18 patients 16 had a face turn (7 with fusion and no strabismus, and 9 without fusion and strabismus) and 2 had a head tilt. Surgery was done after the age of 7 years (average 11 years), the same amount of surgery being done on all four horizontal rectus muscles in patients without strabismus to turn the eyes in the same directio...

• Retroequatorial recessions of the horizontal rectus muscles 10 to 12 mm behind their insertions reduced the amplitude of manifest congenital nystagmus in three patients. Modest improvement of visual acuity occurred in two patients. In a third patient with periodic alternating nystagmus, a compensatory head turn was eliminated by shifting the neutral zone of the nystagmus to the primary position of gaze. In spite of large recessions of the muscle insertions, none of the patients had a functiona...

: The records of 48 patients with congenital nystagmus who required surgery for a significant head turn were reviewed to compare the effectiveness of the surgical techniques. Patients were omitted from the study if the last postoperative visit was less than five months following surgery, or if the surgery was for a vertical head posture. The average preoperative head turn of the 38 patients with horizontal nystagmus was 41.3 degrees with an average postoperative head turn of 11.5 degrees. The ne...

Forty-three patients with congenital nystagmus who underwent surgery in the Ocular Motility Clinic at The Royal Victorian Eye and Ear Hospitar Melbourne, are analysed to assess the effect of different surgical approaches on the abnormal head posture and binocular visual performance. There were 38 patients with a horizontal head turn, and five with a vertical abnormal head posture. In those undergoing horizontal nystagmus surgery the different surgical procedures have been classified as (4 Anders...

: Patients with congenital types of nystagmus, including congenital nystagmus (CN), latent/manifest latent nystagmus (LMLN) and combinations of the two, can be identified by waveform analysis and classified into three unambiguous groups. This categorization by waveform is supported by different clinical signs, including the relationship to strabismus. Strabismus is essential for LMLN but incidental to CN; most CN patients do not have strabismus. Seventy-seven percent of CN patients have a conver...

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...
