Anterior transposition of the inferior oblique and anti-elevation syndrome - how far to go?

: To study the incidence of postoperative anti-elevation syndrome in relation to the magnitude of anterior transposition of the inferior oblique. : A retrospective chart review was conducted for all patients submitted to anterior transposition of the inferior oblique from 2000 to 2020. Anti-elevation syndrome was defined as limitation of elevation of the abducting eye, resulting in a secondary upshoot of the contralateral adducting eye.

Vision screening using a smartphone platform.

Objective: The main aim of this study was to evaluate the performance of a platform designed for pediatricians to screen amblyopia using a smartphone.

Methods: The medical records of consecutive children who received visual screening using a smartphone platform were retrospectively reviewed. The smartphone was used with a flash concentrator case and a software for capturing images of both eyes simultaneously by a photorefraction mechanism.

Two birds, one stone: a surgical approach for third nerve palsy with aberrant regeneration.

Aberrant regeneration in third nerve palsies, linking medial rectus contraction to the levator palpebrae muscle, is a great opportunity for surgical planning to address both the ptosis and horizontal deviation in a single procedure. We report a case of severe ptosis associated with exotropia that was successfully corrected with a single horizontal strabismus surgery owing to aberrant regeneration and discuss the basis underlying the surgical planning.

Vision for the Future Project: Screening impact on the prevention and treatment of visual impairments in public school children in São Paulo City, Brazil.

Objectives: Uncorrected refractive errors are the leading cause of visual impairment in children. In this cross-sectional retrospective study, we analyzed a social visual screening program for school children in São Paulo, Brazil, evaluated its impact on the prevention and treatment of children's visual disabilities, and assessed its epidemiological outcomes to outline suggestions for its improvement.

Methods: First-grade children from public schools were submitted to prior visual screening by their teachers.

Strabismus and Artificial Intelligence App: Optimizing Diagnostic and Accuracy.

Purpose: Clinical evaluation of eye versions plays an important role in the diagnosis of special strabismus. Despite the importance of versions, they are not standardized in clinical practice because they are subjective. Assuming that objectivity confers accuracy, this research aims to create an artificial intelligence app that can classify the eye versions into nine positions of gaze.

Intermittent exotropia evaluation using the propedeutics proposed by Kushner: a 25-year study.

Purpose: To evaluate the clinical and surgical impacts of phenomena that could occur in intermittent exotropia.

Methods: The medical records of intermittent exotropia cases from 1991 to 2014 were retrospectively reviewed. All patients underwent a series of measures, including a protocol to assess monocular occlusion based on the propedeutics proposed by Kushner.

Teratogen exposure and congenital ocular abnormalities in Brazilian patients with Möbius sequence.

Purpose: To assess the sociodemographic profiles, teratogen exposures, and ocular congenital abnormalities in Brazilian patients with Möbius sequence. Method: Forty-four patients were recruited from the Brazilian Möbius Sequence Society. This cross-section comprised 41 patients (age, mean ± standard deviation, 9.

Prevalence of refractive errors in Möbius sequence.

Purpose: To assess the prevalence of refractive errors in Möbius sequence.

Methods: This study was carried out during the Annual Meeting of the Brazilian Möbius Society in November 2008. Forty-four patients diagnosed with the Möbius sequence were submitted to a comprehensive assessment, on the following specialties: ophthalmology, neurology, genetics, psychiatry, psychology and dentistry.

Biometric relationships of ocular components in esotropic amblyopia.

Purpose: To investigate the contribution of the individual ocular components, i.e. anterior chamber depth, lens thickness and vitreous chamber depth, to total axial length in patients with esotropic amblyopia.

Oculometric parameters of hyperopia in children with esotropic amblyopia.

Purpose: To study the oculometric parameters of hyperopia in children with esotropic amblyopia, comparing amblyopic eyes with fellow eyes.

Methods: Thirty-seven patients (5-8 years old) with bilateral hyperopia and esotropic amblyopia underwent a comprehensive ophthalmic examination, including cycloplegic refraction, keratometry and A-scan ultrasonography. Anterior chamber depth, lens thickness, vitreous chamber depth and total axial length were recorded.

[Intraoperative adjustable strabismus surgery under drop anesthesia in patients with Graves' orbitopathy].

Purpose: To report the clinical features of strabismus associated with Graves' orbitopathy, and the results of surgery with adjustable suture under drop anesthesia.

Methods: The charts of 13 patients who had surgical treatment for strabismus related to Graves' orbitopathy at Hospital das Clínicas of University of São Paulo were retrospectively reviewed. Ocular motility, sensorial examination and the follow-up after strabismus correction were studied.

Comparison of the temporal hemifield and nasal hemifield sensitivity in patients with early-onset convergent strabismus.

Objective: To analyze the hypothesis that a reduction in sensitivity of the nasal visual hemifield would lead to an increase in the nasotemporal asymmetry of the visual field in patients under two years of age with early-onset convergent strabismus in comparison with normal patients.

Methods: Both eyes of 66 patients - 33 esotropes and 33 normals - were studied. Patients' age ranged from 7 to 30 years.

[Simplified intraoperative adjustable suture technique for horizontal strabismus surgery: a study of 153 cases].

Purpose: To evaluate the simplified intraoperative adjustable suture technique for horizontal strabismus surgery.

Methods: Data charts of all patients who underwent horizontal strabismus surgery by the simplified intraoperative adjustable suture technique at the Strabismus Department of the "Hospital das Clínicas" of the University of São Paulo in the period from January 2001 to November 2005 were evaluated retrospectively. Using this technique, the adjustment was calculated based on the corneal light reflection, having considered the difference between the measures in the awake state and with the anesthetized patient.

Persistent diplopia and strabismus after cataract surgery under local anesthesia.

Background And Purpose: Diplopia is an infrequent complication described for retrobulbar local anesthesia. The objective of this study is to report the clinical characteristics and treatments for this surgical complication.

Methods: Retrospective study of medical records.

[Strabismic amblyopia: a retrospective study on patients from a university hospital].

Purpose: To evaluate the influence of compliance with treatment, severity of amblyopia and age at the beginning of treatment in patients with strabismic amblyopia submitted to patching.

Methods: The data were selected from medical records of 569 patients seen at the Department of Ophthalmology, University of São Paulo during the period of 1983 to 2000.

Exclusion Criteria: loss of follow-up, age over 12 years, presence of nystagmus and other ocular diseases.

[Sensorial strabismus: a study of 191 cases].

Purpose: To evaluate the charts of patients with sensorial strabismus regarding range of different aspects, such as etiology, the type and the amount of deviation, relationship between the type of deviation and the patient's age when the disease occurred and the surgical outcome.

Methods: A retrospective analysis of data charts of 191 patients seen at the section of Ophthalmology at the University of São Paulo, from September 1990 to July 2002.

Recession and measured, graded anterior transposition of the inferior oblique muscles for V-pattern strabismus: outcome of 44 procedures in 22 typical patients.

Purpose: This study aimed to evaluate the efficacy of recession and graded anterior transposition of the inferior oblique (IO) muscle to correct or to reduce V-pattern strabismus and associated IO overaction.

Methods: The technique used was that proposed by Wright, using the temporal border and the insertion of the inferior rectus as the reference points to locate the new insertion. In a retrospective study, 51 patient histories were analyzed and from this group, 22 patients were selected as most typical examples.
