(Conselho Brasileiro de Oftalmologia, 2003-12-01) Beer, Sandra Maria Canelas [UNIFESP]; Scarpi, Marinho Jorge [UNIFESP]; Minello, Antonieta Antunes [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
PURPOSE: To establish the prevalence of refractive errors, strabismus, amblyopia and anisometropia, among children in a population, using two methods of screening (at school and at the National Polio Vaccination Day). METHODS: We examined 2,640 children, between 0 and 6 years of age. The children, residents of the city São Caetano do Sul, were divided into two groups (A and B). Group A: 476 children, with an age range of a few months to 6 years, had their eyes examined by 10 ophthalmologists and 11 ophthalmology technicians, during the National Polio Vaccination Day (June 20,1998). Group B: 2,164 children attending municipal schools (EMEIs and EMIs), between 4 and 6 years of age, who had their eyes examined by two ophthalmologists during the year of 1998. RESULTS: In group A, the prevalence of strabismus was 3.36% and that of anisometropia was 1.26%. The most common type of refractive error was hypermetropia £ 2D and 14.11% required optical prescription. In group B, the prevalence of strabismus was 1.43%. In the group who failed in the screening, the prevalence of amblyopia was 1.39% and that of anisometropia was 2.8%. The most common type of refractive error found was hypermetropic astigmatism and 56.48% required optical prescription. CONCLUSION: The prevalence of the ocular findings in children in São Caetano do Sul, although being a city with a privileged socioeconomic profile, is similar to that reported in the literature. Ophthalmic examination on National Polio Vaccination Day showed to be an efficient screening tool.

(Conselho Brasileiro de Oftalmologia, 2000-10-01) Cronemberger, Monica Fialho [UNIFESP]; Tabuse, Marcia Keiko Uyeno [UNIFESP]; Aguilar, Luis Tibiriça [UNIFESP]; Costa, Marcelo Fernandes Da; Ferraretto, Ivan; Associação de Assistência à Criança Defeituosa; Universidade Federal de São Paulo (UNIFESP); Associação de Assistência à Criança Deficiente
Purpose: To study ocular findings in patients with meningomyelocele. Methods: A retrospective study of 72 patients with myelomeningocele was performed to evaluate ocular motility disorders, refractive errors and indirect ophthalmoscopy findings. Results: In a group of 72 patients with myelomeningocele, aged 5 month -- 18 years, 64 (88.9%) had hydrocephalus. Of this group of 64 patients, 36 (56.3%) had strabismus, 21 (58.3%) of whom were esotropic, and 13 (36.1%) exotropic, 1 (2.8%) exophoric and 1 (2.8%) presented sometimes esotropia and sometimes exotropia. Of the total of 72 studied patients, 38 (52.8%) had strabismus. Anisotropia was found in 16 (22.2%) patients, 14 (87.5%) with an A pattern and 2 (12.5%) with a V pattern. The most frequent refractive error was hyperopia, found in 64 (44.4%) eyes. All the 16 patients with anisotropia had hydrocephalus. Atrophy of the optic nerve was found in 9 (12.5%) patients. Conclusion: Myelomeningocele associated with hydrocephalus had a higher percentage of strabismus than the normal population.

Acurácia da medida da inserção dos músculos retos com tomografia de coerência óptica em adultos submetidos a cirurgias de estrabismo
(Universidade Federal de São Paulo (UNIFESP), 2017-03-29) Rossetto, Julia Dutra [UNIFESP]; Allemann, Norma [UNIFESP]; Mattos Júnior, Rubens Belfort [UNIFESP]; http://lattes.cnpq.br/4270399167335564; http://lattes.cnpq.br/0956596522261307; http://lattes.cnpq.br/8314526091344602; Universidade Federal de São Paulo (UNIFESP)
Purpose: To assess the accuracy of anterior segment optical coherence tomography (AS-OCT) in measuring the distance of extraocular muscle (EOM) insertion to the limbus to improve preoperative assessment of adult patients undergoing strabismus surgery. Methods: A reliability analysis at an institutional practice performed in adult patients scheduled for strabismus surgery on rectus muscles. The distance between the EOM insertion and the limbus was measured preoperatively with AS-OCT. The value was compared to intraoperative measurement obtained with calipers. Additional measurements included the limbus-anterior chamber angle distance with AS-OCT and the axial length with IOLMaster. The main outcome measure was the greement between preoperative AS-OCT and intraoperative measurements. A difference of ≤ 1 millimeter (mm) was "clinically acceptable". Results: 144 muscles were analyzed from 74 patients. 31 of 33 reoperated muscles were successfully imaged. AS-OCT measurements were within 1 mm of intraoperative measurements in 77% of all the muscles. The accuracy was higher for muscles with no prior surgery (83%), as compared to re-operated muscles (58%). Although the accuracy decreased when comparing reoperations to primary surgeries for the medial (79 to 63%; p=0.09; 95%CI, -1.38 to 0.11) and the lateral rectus (81 to 49%; p=0.11; 95%CI, -2.06 to 0.22), the difference was not significant. No correlation between limbus-anterior chamber angle distance and axial length was established. Conclusions: AS-OCT is valuable in identifying EOM insertions in primary strabismus surgeries, but the accuracy decreases in re-operations. The intraoperative measure performed before the detachment of the muscle's tendon and the use of limbus as a reference point in the OCT proved to be suitable for performing the measurements.

(Conselho Brasileiro de Oftalmologia, 2012-04-01) Hopker, Luisa Moreira [UNIFESP]; Zaupa, Priscila Fernandes [UNIFESP]; Lima Filho, Acácio Alves de Souza [UNIFESP]; Cronemberger, Monica Fialho [UNIFESP]; Tabuse, Marcia Keiko Uyeno [UNIFESP]; Nakanami, Célia Regina [UNIFESP]; Allemann, Norma [UNIFESP]; Mendonça, Tomás Scalamandré [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
PURPOSE: To evaluate the change in ocular motility and muscle thickness measured with ultrasonography after intramuscular injection of bupivacaine and botulinum toxin A. METHODS: Eight patients (five female) were enrolled to measure ocular motility prior and 1, 7, 30 and 180 days after one injection of 2 ml of 1.5% bupivacaine and 2.5 U of botulinum toxin A in agonist and antagonist muscles, respectively, of eight amblyopic eyes. Muscle thickness was measured prior and on days 1, 7 and 30 after injection using 10-MHz ultrasonography (eyelid technique). RESULTS: Mean change in alignment was 10 prism diopters after 180 days (n=6). An average increase of 1.01 mm in muscle thickness was observed after 30 days of bupivacaine injection and 0.28 mm increase was observed after botulinum toxin A injection, as measured by ultrasonography. Lateral rectus muscles injected with bupivacaine had a mean increase of 1.5 mm in muscle thickness. CONCLUSION: In this study, a change in ocular motility was observed after 180 days of intramuscular injection of bupivacaine and botulinum toxin in horizontal extraocular muscles. Overall, there was an increase of muscle thickness in both botulinum toxinum A and bupivacaine injected muscles after 30 days of injection when measured by ultrasonography. This change was more pronounced on lateral rectus muscles after bupivacaine injection.

Comparação entre os métodos de injeção de toxina botulínica em músculo ocular externo com o uso do eletromiógrafo e com o uso da pinça de Mendonça
(Conselho Brasileiro de Oftalmologia, 2005-04-01) Mendonça, Tomás Fernando Scalamandré [UNIFESP]; Cronemberger, Monica Fialho [UNIFESP]; Lopes, Márcia Cordeiro Emery [UNIFESP]; Nakanami, Célia Regina [UNIFESP]; Bicas, Harley Edson Amaral; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)
PURPOSE: To compare two methods of botulinum toxin A (BTA) injection into the extraocular muscle (EOM): the electromyographically (EMG) guided injection and the injection using Mendonça's forceps. METHODS: Twenty-nine (29) patients with strabismus and low visual acuity in one eye were examined at the Department of Ophthalmology of UNIFESP. They were divided into 2 groups - group I with 17 patients receiving the botulinum toxin A injection using Mendonça's forceps, and group II with 12 patients receiving the toxin with electromyographical guidance. The patients of both groups were examined on the 7th and 14th day after intervention and the outcome of both methods of botulinum toxin A injection were compared. Friedman and Mann-Whitney correlation tests were used in the statistical analysis of the data. RESULTS: Although the follow-up examinations on the 7th and 14th days showed a different behavior between both methods, there was no statistically significant difference between the mean values of the correction attained in both groups at the end of this study. CONCLUSION: No statistically significant difference was shown between the two groups. Mendonça's forceps can be a safe alternative to electromyography to locate an extraocular muscle for botulinum toxin A injection.

Correção de hipotropia na posição primária do olhar mediante a tenectomia unilateral do músculo oblíquo superior próximo a inserção em estrabismo essencial
(Conselho Brasileiro de Oftalmologia, 1999-10-01) Simone, Finzi; Goldchmit, Mauro; Souza-dias, Carlos [UNIFESP]; Santa Casa de São Paulo Departamento de Oftalmologia; New England Medical Hospital; Universidade Santo Amaro Departamento de Oftalmologia; Universidade Federal de São Paulo (UNIFESP); Santa Casa de São Paulo Faculdade de Ciências Médicas
Purpose: Horizontal strabismus is commonly associated with vertical deviations which can be a result of a dysfunction of the vertical rectus, oblique muscle or both. Overaction of the superior oblique muscle (SO) results in hypotropia (HoT) in primary position of gaze (PP). The aim of this study was to evaluate the correction of HoT in PP after unilateral tenectomy of the superior oblique muscle close to its scleral insertion. Patients and Methods: We retrospectively studied, from 1977 until 1996, charts of 15 patients with SO overaction and hypotropia in PP greater than 4D who underwent unilateral superior oblique tenectomy close to its insertion at Hospital Santa Casa de São Paulo (12 patients), University of Santo Amaro (2 patients) and private clinic of one of the authors (CSD, 1 patient). The mean preoperative deviation in PP was 9D. The mean preoperative superior oblique overaction was 1.7 (measured by a cross system rating). Results: The mean correction of the HoT was 4.67D ± 5.09D (-5D to 15D), (H = 6.032; p = 0.014). The mean correction of SO overaction was 0.87 ± 0.88 + (0 - 2). According to the horizontal deviation, ET and XT, there was no significant mdifference in the correction of the HoT. Conclusion: For HoT of 15D or less we found a mean correction of 51.82% of its preoperative value. Unilateral tenectomy has shown to be an effective technique for the correction of vertical deviation in PP in our study.

(Conselho Brasileiro de Oftalmologia, 2003-08-01) Meireles-teixeira, Jorge [UNIFESP]; Moya, Marcos Pitarello [UNIFESP]; Cuperman, Jairo [UNIFESP]; Mendonça, Tomás [UNIFESP]; Nakanami, Célia [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
PURPOSE: To compare the use of non-steroid anti-inflammatory drugs (NSAID) with steroids in the follow-up of strabismus surgery, regarding inflammation control. METHODS: All patients underwent resection-recession surgery. Both groups used the same antibiotic eye-drop. One group used NSAID (ketorolac tromethamine- Acular®) and the other, prednisolone, 0.12% - Pred Mild®, for 21 days. They were examined with slit-lamp and ectoscopy to evaluate IOP (comparing with the fellow eye), edema, hyperemia and comfort. RESULTS: Of a total of 23 patients, 15 were treated with NSAID and 12 with steroid. Regarding comfort, edema and IOP there was no important difference between the NSAID and steroid groups. However, when we analyzing hyperemia, there were 5 (33.3%) patients in the NSAID group with ++/4 of hyperemia at the 21st postoperative day and only 1 (8.3%) patient in the steroid group. There were also three granulomas (20%) in the NSAID group and none in steroid-treated patients. CONCLUSION: For resection-recession surgeries, procedures that induce a greater inflammatory response, the use of NSAID is not advisable.

Purpose: To evaluate the genetic aspects of strabismus. Methods: Ophthalmic and orthoptic evaluations were performed prospectively on 110 strabismic probands and 478 relatives. We used 3 different criteria in the diagnosis of strabismus: primary diagnosis (dx1) defined as any manifest horizontal or vertical deviation, a secondary diagnosis (dx2) including esophoria (>7 prism diopters) or exophoria (>9 prism diopters), and a tertiary diagnosis (dx3) including abnormal fusional amplitudes, accommodative convergence/accommodation (AC/A) ratio, and/or stereopsis; monofixation syndrome; 4 prism diopters base out; and/or abnormal Maddox test responses. Analyses were carried out within mating types. Results: Hypotheses of autosomal dominant or recessive inheritance with no sporadics were rejected. Based on the dx1, 25% of the families had more than one individual affected and there was vertical transmission in 13%; adding dx2 there were 36% of the families with more than one affected and 21% had vertical transmission; and adding dx3, there were 73% with more than one affected and 51% with vertical transmission. Conclusions: There is evidence for a pattern consistent with an autosomal dominant form of strabismus in most families.

To determine the changes in the cross-sectional area (CSA) of myofibers and their subtype distribution based on the myosin isoform expression after bupivacaine (BUP) injection in the EOM of rabbits and help the understanding of strabismus correction after BUP injection in the clinical practice. A total of 32 rabbits received 0.3 mL of 1.5% BUP in the superior rectus muscle (SR) of the right eye (OD) and were sacrificed at days 7, 28, 60, and 92. Additional eight untouched rabbits were included as controls. Hematoxylin and eosin staining was performed, and ImageJ software was used to measure CSA. Immunohistochemical analysis was performed to analyze the proportion of myofibers positive for myosin types 1 (slow), 2 (fast) and embryonic. Myofiber area measurement decreased 7 days after BUP injection [SR, 1271 +/- 412 mu m(2) (control) to 909 +/- 255 mu m(2) (day 7)] after BUP injection, followed by an increasing trend after 28 days and normalization after 92 days [SR

Mudanças na refração após cirurgia de correção de esotropia
(Conselho Brasileiro de Oftalmologia, 2001-08-01) Vadas, Marcelo F. Gaal; Monteiro, Mário Luiz Ribeiro; Gomes, José Álvaro Pereira [UNIFESP]; Universidade de São Paulo (USP); Santa Casa de São Paulo Departamento de Oftalmologia; Universidade Federal de São Paulo (UNIFESP)
Purpose: To evaluate changes in refraction and corneal curvature following surgery for correction of acquired esotropia. Methods: 42 eyes of 21 patients with acquired moderate angle esotropia without any other form of strabismus were prospectively enrolled and submitted to a complete ophthalmological examination followed by recess/resect procedure in a single eye. Data from the fellow eye were selected as control. Ophthalmological assessment was carried out preoperatively, 1 month after surgery and 6 months after surgery, where astigmatism was compared using vector analysis and the polar value concept. Results: The eyes submitted to surgery revealed a significant (p<0.05) decrease in spherical equivalent, from 3.28 ± 1.98 diopters to 3.05 ± 1.95 diopters. Refraction data disclosed a significant increase in the 90° component of net astigmatism, from 0.458 ± 0.594 diopters to 1.002 ± 0.718 diopters, which was also observed in keratometric readings:1.083 ± 0.560 diopters to 1.690 ± 0.591 diopters. Surgically induced astigmatism, assessed using refraction data was 0.63 ± 0.27 diopters at an average axis of 92.30 ± 14.91 degrees, and 0.71 ± 0.27 diopters at an average axis of 94.45 ± 15.69 degrees as obtained by keratometric readings. This is visually demonstrated by the corneal topography difference map. Conclusions: There is a statistically significant and clinically relevant increase in with-the-rule astigmatism in esotropic patients submitted to monocular recess/resect surgery. This change is stable at a 6 month follow-up and is associated with a decrease in mean spherical equivalent.

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. Forty-three patients were cooperative and able to undertake the ophthalmological examination. Twenty-two (51.2 %) were male and 21 (48.8%) were female. The average age was 8.3 years (from 2 to 17 years). The visual acuity was evaluated using a retro-illuminated logMAR chart in cooperative patients. All children were submitted to exams on ocular motility, cyclopegic refraction, and fundus examination. RESULTS: From the total of 85 eyes, using the spherical equivalent, the major of the eyes (57.6%) were emmetropics (>-0.50 D and <+2.00 D). The prevalence of astigmatism greater than or equal to 0.75 D was 40%. CONCLUSION: The prevalence of refractive errors, by the spherical equivalent, was 42.4% in this studied group.

Background: West syndrome (WS) is a type of early childhood epilepsy characterized by progressive neurological development deterioration that includes vision.Aim: To demonstrate the clinical importance of grating visual acuity thresholds (GVA) measurement by sweep visually evoked potentials technique (sweep-VEP) as a reliable tool for evaluation of the visual cortex status in WS children.Methods: This is a retrospective study of the best-corrected binocular GVA and ophthalmological features of WS children referred for the Laboratory of Clinical Electrophysiology of Vision of UNIFESP from 1998 to 2012 (Committee on Ethics in Research of UNIFESP no 0349/08). the GVA deficit was calculated by subtracting binocular GVA score (logMAR units) of each patient from the median values of age norms from our own lab and classified as mild (0.1-0.39 logMAR), moderate (0.40-0.80 logMAR) or severe (>0.81 logMAR). Associated ophthalmological features were also described.Results: Data from 30 WS children (age from 6 to 108 months, median = 14.5 months, mean +/- SD = 22.0 +/- 22.1 months; 19 male) were analyzed. the majority presented severe GVA deficit (0.15-1.44 logMAR; mean +/- SD = 0.82 +/- 0.32 logMAR; median = 0.82 logMAR), poor visual behavior, high prevalence of strabismus and great variability in ocular positioning. the GVA deficit did not vary according to gender (P = .8022), WS type (P = .908), birth age (P = .2881), perinatal oxygenation (P = .7692), visual behavior (P = .8789), ocular motility (P = .1821), nystagmus (P = .2868), risk of drug-induced retinopathy (P = .4632) and participation in early visual stimulation therapy (P = .9010).Conclusions: the sweep-VEP technique is a reliable tool to classify visual system impairment in WS children, in agreement with the poor visual behavior exhibited by them.

To evaluate the efficacy of botulinum toxin injection in the treatment of horizontal strabismus in children with cerebral palsy. METHODS: A group of 24 patients, age 6 - 156 months, with cerebral palsy and horizontal strabismus (17 esotropias ranging from 25 to 45 PD and 7 exotropias ranging from 20 to 45 PD) were treated with botulinum toxin (34 medial rectus and 14 lateral rectus muscles). The children underwent full ophthalmic examination. The injection treatment was performed after sedation using Mendonça's forceps. The follow-up was done after 7 days, 15 days and monthly. Deviation less or equal of 10 PD after 6 months of follow-up was considered successful. However, if patients did not achieve this result a second application could be performed. RESULTS: In the group of esotropia (n=17) 47.1% had successful results with only one application after two years of follow-up. All of these patients had previous deviation less than or equal to 35 PD. In the exotropia group a single injection was not sufficient to achieve successful result. The side effects included: subconjutival hemorrhage in 4 (16.7%) patients, transient vertical deviation in 4 (16.7%) and transient ptosis in 22 (91.7%). CONCLUSION: The use of botulinum toxin was a good alternative in the treatment of children with cerebral palsy and esotropia.
