PURPOSE: Mobius sequence is a rare disorder that results from underdevelopment of the sixth and seventh cranial nerves, with subsequent facial weakness and impairment of ocular abduction. Approximately half of the affected patients have esotropia with limitation of extraocular movements. This study retrospectively reviews the long-term outcome of strabismus surgery for such patients. METHODS: The long-term follow-up results in five children with Mobius sequence, who were observed after strabismus surgery for congenital esotropia, were analyzed...

BACKGROUND: Fusional amplitudes are important for clinical practice in diagnosing and managing binocular vision anomalies. Several measurement methods can be used to assess fusional amplitudes. However, those methods are not interchangeable, and measurement repeatability has been questioned. OBJECTIVES: To compare the normative values of tests for the measurement of fusional vergence and to investigate sources of heterogeneity of diagnostic accuracy including: age, variation in method of assessment, study design and size, type (convergent, divergent, vertical, cyclo) and severity of strabismus (constant/intermittent/latent)...

The author discusses several of Albrecht Dürer's selfportraits. In some portraits his eyes are straight and in some others a divergent squint is present. Did Dürer do this on purpose or whas the squint indeed intermittently present? Analysis of the portrait of his mother gave the explanation.

PURPOSE: This study aims to evaluate the effect of bupivacaine injection at 1.5% combined with recession of the antagonist rectus muscle to treat sensory strabismus in adult patients. METHODS: Nine patients with a horizontal deviation, visual acuity of <20/60 in the worst-seeing eye, and no previous strabismus surgery were selected. Patients with vertical strabismus were excluded. Lateral rectus (LR) recession was performed in patients with exotropia and medial rectus (MR) recession in patients with esotropia according to Park's Table, as modified by Wright...

INTRODUCTION: Recently, to reduce the incidence of oculocardiac reflex (OCR) in strabismus surgery, retrobulbar block and anticholinergic drugs or local anesthesia are also used. The present study evaluated the effects of Tetracaine eye drop as a topical nerve blocker on OCR during strabismus surgery. METHODS AND MATERIALS: In this randomized trial, 70 strabismus surgery candidates were randomly divided into placebo or synthetic teardrop (E) and Tetracaine eye drop (T) groups, so 3 drops of each solution were dropped in four directions of patients' eye immediately after applying anesthesia and before surgery...

PURPOSE: The information about superior rectus (SR) recession in cases with SR contracture coexisting with superior oblique palsy (SOP) is very limited in previous literature. The aim of this study is to evaluate the effect of SR recession, as a combined procedure with inferior oblique (IO) disinsertion, in long-standing SOP with secondary SR contracture. METHODS: The medical records of the 145 patients operated for SOP were retrospectively reviewed and 15 patients who underwent SR recession met the inclusion criteria...

PURPOSE: To be cross-eyed is a wide-spread dysfunction of the eye and squinting is currently regarded as unattractive. However, in ancient times, societies saw squinting as a sign of piety or even beauty. Even Venus was depicted heterophoric quite often. The most famous artist who was cross-eyed was Giovanni Francesco Barbieri (*08.02.1591; †22.12.1666, both Italy). His nickname was "Il Guercino" which means "the squinter." This article reflects on vision and art from the perspective of a cross-eyed person...

PURPOSE: To report the surgical outcomes of the superior oblique tuck procedure in the management of superior oblique palsies performed at a single centre over a 25-year period. METHODS: A retrospective study of superior oblique tuck performed as a primary and secondary procedure by a single surgeon over a 25-year period between 1992 and 2016. We evaluated patient demographics, the angle of deviation pre- and post-surgery in prism dioptres (PD), amount of muscle tuck surgery performed (mm), complications (iatrogenic Brown's Syndrome) and improvement of diplopia post-operatively...

INTRODUCTION: We report a case of inferior oblique (IO) muscle adherence with fat adherence, which developed following unilateral IO anteriorization (IOAT). METHODS: A 14-year-old child with V pattern left exotropia, bilateral IO overaction, bilateral dissociated vertical deviation (DVD), and strabismic amblyopia (OS) underwent recess/resect procedure along with IOAT. He developed consecutive esotropia and drooping of upper eyelid with marked limitation of levoelevation (-4)...

OBJECTIVES: To report the clinical outcomes of a new modification to muscle belly union surgery in heavy eye syndrome. METHODS: Muscle belly union was performed in patients with large-angle esotropia and characteristic findings of heavy eye syndrome on orbital imaging. After isolation of superior and lateral rectus muscle and passing a single armed suture in each muscle belly, approximation was achieved via tying of both arms of separate sutures together. Medial rectus (MR) was also recessed considering the results of the intraoperative force duction test...

PURPOSE: IINS is associated with mild/moderate visual impairment, strabismus and compensatory head postures (CHP), which can negatively impact quality of life. Standard visual acuity assessments tend to underestimate the effect of IINS on visual functioning. Published evidence on the effect of INS on quality of life is slowly emerging. Our study examines visual functioning of adults with IINS using the National Eye Institute Visual Function Questionairre-25 (VFQ-25). METHODS: 38 participants were recruited to participate in the study...

Strabismus was a known eye misalignment since the Hippocratic era (ca 5th century BC). Hippocrates and his followers were the first to introduce the hypothesis of a hereditary condition. Many ancient Greek physicians like Galen (ca 2nd AD) provided several definitions, while Paul of Aegina (625-690 AD) was the scholar who introduced a method to treat it. Paul used a full face mask and an oil lamb to guide the eyeballs toward the desired direction. It seems that this approach endured for centuries to come. During 11th century AD in Constantinople, the Byzantine scholar and politician Michael Constantine Psellus (ca 1020-1105 AD) composed a series of philosophical, religious, political and scientific treatises...

AIM: A study was carried out to determine if the presence of microtropia with identity is a reliable indicator for the presence of amblyopia, and likely need for occlusion, following optical treatment in "straight-eyed" anisometropic children. METHOD: A retrospective case note review was carried out of all children referred from Orthoptic school vision screening during a 10-year period. Children who had unequal visual acuity, no manifest strabismus and who were prescribed spectacles to correct anisometropia (inter-ocular difference one dioptre or more in any meridian) were included in the study...

INTRODUCTION: Multiple different procedures have been proposed to address complete sixth nerve palsy with severe abduction limitation. In this study, we report a modification of the Hummelsheim's procedure. It is in fact muscle pulley transposition that obviates the need for tenotomy or muscle splitting. For the first time, Muraki and Nishida proposed this technique. MATERIALS AND METHODS: Patients with large angle esotropia and abduction limitation of minus four or greater were enrolled...
