CONTEXT: Botulinum toxin injection is widely used for many purposes, including neuromuscular diseases, movement disorders and strabismus. OBJECTIVE: To evaluate and report the impact of botulinum toxin injection on ocular surface parameters in patients with strabismus. PARTICIPANTS: Twenty-six consecutive patients who underwent botulinum toxin A injection for ocular misalignment were recruited for this prospective study. MATERIALS AND METHODS: Testing of ocular surface parameters including tear break-up time (BUT), lissamine green (LG) staining and Schirmer test (under topical anesthesia) was performed, and Ocular Surface Disease Index (OSDI) questionnaire scores were recorded before and at certain time points after injection (one week, two weeks, one month, three months and six months after botulinum toxin A injection)...

PURPOSE OF REVIEW: To examine the common and serious complications of strabismus surgery, emphasizing prevention, identification, and treatment. RECENT FINDINGS: Confusions involving incorrect procedures and patients can occur despite the Universal Protocol, but should be preventable and treatable. Damage to structures adjacent to muscles and scleral perforations should be prevented by careful surgical technique and effective magnification. Orbital inflammations and anterior segment ischemia can usually be treated effectively...

BACKGROUND: Simultaneous eye muscle and lens surgery in patients with strabismus and lens abnormalities offers the advantage of avoiding staged surgery. METHODS: Thirty-three combined strabismus and lens surgeries were performed on 30 patients who ranged in age from 22 months to 91 years. Fifteen of the strabismus procedures were performed for esotropia, 12 for exotropia, 4 for vertical deviations, and 2 for combined vertical-horizontal deviations. Surgical amounts often were reduced to lessen the risk of overcorrection, to minimize anesthetic requirements (when using topical rather than general anesthesia), or to avoiding additional surgery on the contralateral or ipsilateral eye...

UNLABELLED: In our Department of Orthoptics we have seen an increasing number of patients suffering from diplopia after cataract surgery with IOL implantation. Between 1993 and 1997 the total number of patients with this problem was 24 (2.7 % of all patients, mean age 71 years, age range 38-88). We addressed the question of whether there is a common pattern of motility dysfunction. METHODS: After evaluation of the clinical history and the basic ophthalmological findings the following parameters were examined: binocular function (Bagolini test), squint angles (Maddox cross), ocular motility...

PURPOSE: In the Hirschberg eye position test, the ratio of strabismic angle to decentration of the corneal reflex is dependent on two biometric parameters of the eye: the radius of the corneal curvature and the depth of the anterior chamber. This study was designed to confirm whether the Hirschberg conversion ratio (HR) previously determined for adults can be used for children of various ages despite structural growth of the eye. METHODS: For 262 eyes of 131 children with strabismus (age range, 6 months to 11 years), the radius of the corneal curvature was measured with an auto-keratometer and the anterior chamber depth with an A-scan ultrasound unit under general anesthesia before the surgery...

OBJECTIVE: Intermittent exotropia is a common form of childhood strabismus that has a late onset and presents a difficult and frustrating management dilemma. Surgical treatments have a high recurrence rate, and multiple surgeries often are required to achieve a desirable motor outcome. This study presents long-term observations on the use of botulinum toxin for the treatment of intermittent exotropia in children. DESIGN: This study is a nonrandomized, case-controlled study of consecutive pediatric patients who had intermittent exotropia...

BACKGROUND: Infantile esotropia has an onset during early infancy when visual cortical connections are established for binocular fusion and stereopsis. The goal of early treatment is to achieve normal binocular alignment and a favorable sensory outcome. OBJECTIVE: To determine the long-term effects of the use of botulinum toxin for the management of infantile esotropia in children. PATIENTS: Seventy-six neurologically normal children ranging from 4 to 48 months of age were entered consecutively into the study after being given the initial diagnosis of infantile esotropia with a mean strabismic angle of 33 prism diopters...

INTRODUCTION: The oculocardiac reflex causes severe bradycardic arrhythmias and is a frequent complication during surgical manipulation at the medial rectus muscle. The purpose of this study was to evaluate the influence of lidocaine administered topically on the muscle on the incidence of the oculocardiac reflex. PATIENTS AND METHODS: After obtaining informed consent, 140 patients with strabism or retinal surgery were included in this study. All patients received standard premedication and anesthesia and were randomly assigned to two groups...

In humans, esotropia of early onset is associated with a profound asymmetry in smooth pursuit eye movements. When viewing is monocular, targets are tracked well only when they are moving nasally with respect to the viewing eye. To determine whether this pursuit abnormality reflects an anomaly in cortical visual motion processing, we recorded eye movements and cortical neural responses in nonamblyopic monkeys made strabismic by surgery at the age of 10-60 d. Eye movement recordings revealed the same asymmetry in the monkeys' pursuit eye movements as in humans with early-onset esotropia...

Since april 1993, we have an out-patient surgery department in our university hospital. We report our experience of out-patient surgery in 80 strabismic patients> We have divided the 80 patients in a pediatric group and an adult group. We describe the conditions of admission for out-patient surgery, the method of anesthesia, the development of the procedure. Surgical techniques do not differ from those used in hospitalized patients. We report our statistics concerning age, diagnosis, type and length of surgery of our 80 patients...

An instrument for the quantitative analysis of the passive forced traction test on strabismic patients under anesthesia is described. This spring dynamometer measures the grams of force required to displace the eye from its rest position into the various fields of rotation of the globe. Measurements on a control population are compared with both non-restrictive and restrictive strabismic patients. Characteristics of various types of restrictions encountered are mentioned as an aid to more precise diagnosis of specific strabismic problems...

Intraoperative continuous-registration length and tension curves of attached and detached eye muscles were made in 18 strabismic patients under general anesthesia. For relaxed eye muscles, we found an exponential relation between length and tension. An increased stiffness was quantified in Duane's syndrome, Graves' disease, orbital-floor fracture, and superior oblique palsy. The stiffnesses of agonist and antagonist were remarkably similar, not only in uncomplicated squint, but also when only one of the two had initially become stiffer...

In six 3-week-old kittens, the tendon of the lateral rectus muscle of one eye was sectioned under anaesthesia in order to induce an esotropic (nasally-directed) squint. At maturity, the pattern electroretinogram (PERG) and pattern visual evoked response (PVER) were recorded under anaesthesia to phase-reversal at 1.67 Hz of a 0.5c/deg square wave grating pattern of 75% contrast. Refraction was determined by retinoscopy and confirmed by recording the PERG for different trial lenses. The amplitude and time-to-peak of the PERG and PVER were compared between operated and unoperated eyes, and with the responses of one normal and two sham-operated cats...

Retinotopy and binocular responsiveness were studied extracellularly in a total of 278, 61, 110 and 275 cells sampled in areas 17, 18, 19 and Clare-Bishop (CB) of Siamese cats. The misalignment of the visual axes of the two eyes was determined by the pupil reflex method in the behaving animal. The recording sessions were conducted under N2O anesthesia, supplemented with continuous infusion of short-lasting anesthetics (Saffan, Glaxo) and muscle relaxants (Gallamine triethiodide) using two types of visual stimulators presenting two-dimensional (2D) motion stimuli and the visual cues for three-dimensional (3D) motion...
