Influence of upper blepharoplasty on intraocular lens calculation.

PURPOSE: To determine the effect of upper blepharoplasty on corneal topography and intraocular lens power calculation using Galilei and IOLMaster. METHODS: Thirty patients submitted to upper blepharoplasty from May 2014 to March 2017 at the Hospital Oftalmológico de Sorocaba (São Paulo, Brazil) were included in this observational case series. All patients underwent imaging sessions with Galilei and IOLMaster preoperatively (baseline) and at 1 and 6 months postoperatively. Primary outcome measures using both devices included flattest, average, and steepest corneal curvature, corneal astigmatism, and blepharoplasty-induced corneal astigmatism. Determination of axial length and lens power calculation were performed using only IOLMaster (Holladay formula). Paired t-test and vectorial analysis were used for statistical analysis. RESULTS: Sixty eyes from 30 patients were prospectively included. Vectorial analysis showed that 6 months after surgery, blepharoplasty induced on average 0.39 D and 0.31 D of corneal astigmatism, as measured with Galilei and IOLMaster, respectively. IOLMaster measurements showed that average corneal curvature (44.56 vs 44.64 D, p=0.01), steepest corneal curvature (45.17 vs 45.31, p=0.01) and corneal astigmatism (1.22 vs 1.34, p=0.03) were higher 6 months after surgery. IOLMaster measurements also showed that intraocular lens power was significantly smaller 6 months after surgery (22.07 vs 21.93, p=0.004). All other parameters showed no change for comparisons between baseline and 6 months (p>0.05 for all comparisons). CONCLUSION: Upper eyelid blepharoplasty influenced intraocular lens calculation using the IOLMaster. However, the influence was not clinically significant. No topographic changes were found using Galilei.

RESUMO Objetivo: Determinar o efeito da blefaroplastia superior na topografia corneana e no cálculo do poder das lentes intraoculares usando Galilei e IOLMaster. Métodos: Trinta pacientes submetidos a blefaroplastia superior de maio de 2014 a março de 2017 no Hospital Oftalmológico de Sorocaba, São Paulo, Brasil foram incluídos neste estudo de série de casos observacional. Todos os pacientes foram submetidos a sessões de imagem com Galilei e IOLMaster antes da cirurgia (exame de base) e no 1º e 6º mês pós-operatório. Os resultados primários utilizando os dois aparelhos incluíram ceratometria, astigmatismo corenano e astigmatismo corneano induzido pela blefaroplastia. O comprimento axial e o cálculo do poder da lente intraocular foram realizados unicamente com o IOLMaster (fórmula de Holladay). Teste-t pareado e análise vetorial foram usados na análise estatística. Resultados: Sessenta olhos de 30 pacientes foram incluídos prospectivamente. A análise vec­torial mostrou que após 6 meses da cirurgia, a blefaroplastia superior induziu na média 0,39 D de astigmatismo corneano medido com o Galilei e 0,31 D com IOLMaster. As medidas com o IOLMaster mostraram que a ceratometria média (44,56 vs 44,64 D, p=0,01), ceratometria máxima (45,17 vs 45,31, p=0,01) e o astigmatismo corneano (1,22 vs 1,34, p=0,03) foram maiores após 6 meses da blefaroplastia. As medidas com IOLMaster mostraram que o poder da lente intraocular foi significativamente menor 6 meses após a blefaroplastia (22,07 vs 21,93, p=0,004). Todos os outros parâmetros não mostraram mudanças entre o pré-operatório e o 6º mês da cirurgia (p>0,05 para todas as comparações). Conclusões: A blefaroplastia superior influenciou o cálculo da lente intrao­cular utilizando o IOLMaster. Contudo, a influência não foi cli­­nicamente significativa. Não foram encontradas mudanças topográficas com o Galilei.

Topical tacrolimus for the treatment of severe allergic keratoconjunctivitis in children.

PURPOSE:: Administration of eye drops containing antihistamines or sodium cromoglycate and its derivatives for the treatment of allergic keratoconjunctivitis is often insufficient and usually requires the addition of corticosteroids. However, the risk of complications, such as glaucoma and cataract, limits the use of corticosteroids to short courses, resulting in inadequate long-term treatment response. Immunosuppressive drugs have been considered as a valid alternative to steroids for atopic keratoconjunctivitis and vernal keratoconjunctivitis. This study aimed to evaluate the use of topical tacrolimus (TCL) in improving the clinical signs of severe allergic keratoconjuctivitis in children. METHODS:: Patients with severe allergic keratoconjunctivitis associated with corneal epitheliopathy, gelatinous limbal infiltrates, and/or papillary reaction, along with a history of recurrences and resistance to conventional topical anti-allergy agents, were included in this open clinical trial. Patients were treated with 0.03% TCL ointment for ocular use. A severity score ranging from 0 to 9, with 9 being the highest and 0 being the lowest, was assigned based on signs observed on biomicroscopy prior to and following TCL treatment. RESULTS:: Analyses included 66 eyes of 33 patients. After a mean follow-up period of 13 months (range, 12-29 months), TCL treatment significantly decreased the mean symptom score severity for the right (from 5.56 ± 1.18 to 2.76 ± 1.5; p<0.001) and left (from 5.94 ± 1.16 to 2.86 ± 1.64; p<0.001). CONCLUSION:: Topical TCL was effective and significantly improved the clinical signs of allergic keratoconjuctivitis in children. Thus, it is a potential new option for severe and challenging cases of ocular allergy.

RESUMO Objetivos: O tratamento da ceratoconjuntivite alérgica baseado em colírios que contenham anti-histamínicos ou cromoglicato de sódio e seus derivados geralmente são insuficientes. A adição de corticosteróides geralmente é mandatória. No entanto, o risco de complicações como glaucoma e catarata limita o uso dos corticosteróides em curtos períodos de tratamento resultando em respostas inadequadas a longo prazo. Drogas imunossupressoras vem sendo consideradas como uma opção terapêutica alternativa válida para as ceratoconjuntivite atópica (AKC) e ceratoconjuntivite vernal (VKC). Este trabalho tem como objetivo avaliar a melhora nos sinais clínicos durante o uso de tacrolimus (TCL) tópico em crianças com ceratoconjuntivites alérgicas. Métodos: Pacientes com ceratoconjuntivite alérgica severa associada a ceratites, infiltrados limbares gelatinosos e/ou papilas gigantes, com história de recorrências e resistência ao tratamento anti-alérgico tópico convencional foram incluídos neste estudo. Os pacientes foram tratados com TCL 0,03% pomada tópica para uso ocular. Um escore variando de 0 a 9 foi atribuído para os sinais observados na biomicroscopia antes e depois do tratamento. Quanto maiores os escores, mais severos eram os sinais. Resultados: Foram estudados 66 olhos de 33 pacientes. Antes do tratamento a média do escore para o olho direito foi 5,56 ± 1,18 e para o olho esquerdo 5,94 ± 1,16. Após o tratamento com TCL a média do escore para o olho direito foi 2,76 ± 1,5 e para o olho esquerdo 2,86 ± 1,64 (p<0.001 para os dois olhos). O tempo de seguimento médio foi de 13 meses (12-29 meses). Conclusão: O presente estudo sugere que o TCL tópico foi efetivo e demonstrou resultado satisfatório, com melhora nos sinais clínicos na ceratoconjuntivite alérgica em crianças, constituindo uma nova opção para o tratamento de casos severos de alergia ocular.

Prevalence and antibiotic susceptibility of methicillin-resistant Staphylococcus aureus in ocular infections / Prevalência e suscetibilidade antibiótica de Staphylococcus aureus resistente à meticilina em infecções oculares

PURPOSE: To study the prevalence of methicillin-resistant Staphylococcus aureus among S. aureus ocular infections in a tertiary health center in Brazil and compare antibiotic susceptibility patterns between MRSA and methicillin-susceptible S. aureus isolates. METHODS: Electronic records from the ocular microbiology laboratory of the Universidade Federal de São Paulo were retrospectively reviewed. During a 10-year period (between January 2000 and December 2009) all conjunctivitis, keratitis, and endophthalmitis cases with a positive culture for S. aureus were identified. Antibiotic susceptibility was determined using the Kirby-Bauer disk diffusion method. RESULTS: Five hundred sixty-six S. aureus isolates were identified; of those, 56 (9.9%) were resistant to methicillin. Throughout the 10-year period, Staphylococcus aureus showed a significant increasing trend from 7.55% to 16.18% among overall S. aurues infections (p=0.001) and from 3.7% to 13.16% in conjunctivitis (p=0.001). Conversely, we did not observe the same trend among those with keratitis (p=0.38). Staphylococcus aureus isolates showed higher resistance rates to tobramycin, gentamicin, ciprofloxacin, gatifloxacin, and moxifloxacin when compared with S. aureus isolates (p< 0.001). All cases were susceptible to vancomycin. CONCLUSION: We observed an increasing trend in the overall prevalence of Staphylococcus aureus ocular infections and statistically significant higher resistance rates to commonly used antibiotics compared to Staphylococcus aureus. Our data supports the need for constant bacterial surveillance and should be taken into consideration before initiating empiric treatment of ocular infections.

OBJETIVO: Estudar a prevalência do Staphylococcus aureus resistente à meticilina nas infecções oculares causadas por S. aureus em um centro de saúde terciário no Brasil e comparar o perfil de suscetibilidade antimicrobiana entre as cepas de Staphylococcus aureus resistente à meticilina e S. aureus susceptível à meticilina MÉTODOS: Foi realizada uma análise retrospectiva dos arquivos do laboratório de microbiologia ocular da Universidade Federal de São Paulo e selecionados todos os casos de conjuntivite, ceratite e endoftalmite com cultivo positivo para S. aureus, durante um período de 10 anos (entre janeiro de 2000 e dezembro de 2009). Foi avaliada a prevalência de Staphylococcus aureus resistente à meticilina e comparado o perfil de susceptibilidade antimicrobiano dos Staphylococcus aureus resistente à meticilina e S. aureus susceptível à meticilina. RESULTADOS: Quinhentos e sessenta e seis isolados de S. aureus foram identificados. Desses, 56 (9,9%) apresentaram resistência à meticilina. Durante o período de 10 anos estudado, Staphylococcus aureus resistente à meticilina mostrou uma tendência significante de aumento de 7,6% para 16,2% entre as infecções oculares causadas por S. aureus em geral (p=0,001) e de 3,7% para 13,2% nas conjuntivites (p=0,001). A mesma tendência não foi observada entre as amostras de ceratite (p=0,38). Os isolados de Staphylococcus aureus resistente à meticilina mostraram maiores taxas de resistência à tobramicina, gentamicina, ciprofloxacino, gatifloxacino e moxifloxacino em comparação com os isolados de S. aureus susceptível à meticilina (p<0,001). Todos os casos foram susceptíveis à vancomicina. CONCLUSÃO:Foi observada uma tendência de aumento na prevalência do Staphylococcus aureus resistente à meticilina nas infecções oculares causadas por S. aureus, bem como taxas de resistência significantemente maiores aos antibióticos comumente utilizados na prática oftalmológica. Nossos dados alertam para a necessidade de constante vigilância de resistência bacteriana a antimicrobianos e devem ser considerados na eleição do tratamento empírico das infecções oculares.
