ABSTRACT

ABSTRACT Purpose: To evaluate the use of supratarsal injection of triamcinolone acetonide in severe vernal keratoconjunctivitis (VKC) in children. Methods: Patients included in this open clinical trial were those with severe VKC-associated with keratitis, gelatinous limbal infiltrates, and/or giant papillae, with a history of recurrence and resistance to conventional topical antiallergic agents. Patients were treated with a supratarsal injection of 20 mg triamcinolone acetonide. Results: Analysis included 27 injections in 23 eyes of 17 patients with severe allergic keratoconjunctivitis. Mean age was 12.3 (range: 7-19) years. Mean follow-up time was 39.3 months (SD=19.21). In the 17 patients, the disease was successfully controlled for an average of 3.6 months (range: 1-16), during which allergy symptoms and signs were significantly improved, with complete resolution of lid edema and conjunctival chemosis, significant decline of pannus and keratitis, and reduction of giant papillae size. Conclusion: Treatment of severe, acute VKC in children with supratarsal injection of 20 mg triamcinolone acetonide showed satisfactory results and was well tolerated by patients; it may therefore constitute a safe option for severe and challenging cases. While full disease remission was not achieved, a significant improvement was found in ocular allergy symptoms and signs, with a reduction in the frequency of acute recurrences.


RESUMO Objetivo: Avaliar o uso da injeção supratarsal de triancinolona na ceratocon junti vite primaveril grave (VKC) em crianças. Métodos: Pacientes com VKC grave associada à ceratite, limbo gelatinoso e/ou papilas gigantes, com história de recidivas e resistência a agentes antialérgicos tópicos convencionais foram incluídos neste ensaio clínico. Os pacientes foram tratados com injeção de 20 mg de acetato de triancinolona supratarsal. Resultados: A análise incluiu 23 olhos de 17 pacientes com ceratoconjuntivite alérgica grave. A idade média foi de 12,3 com intervalo de 7-19 anos. O tempo médio de acompanhamento foi de 39,3 meses (DP 19,21). Dos 17 pacientes, a doença foi controlada com sucesso por uma média de 3,6 meses (intervalo 1-16) em que os sinais e sintomas foram significativamente melhorados com resolução completa do edema palpebral e quemose conjuntival, redução significativa de pannus, ceratite e redução do tamanho das papilas gigantes. Conclusão: O tratamento da VKC grave em crianças com injeção supratarsal de 20 mg de acetato de triancinolona mostrou resultados satisfatórios, sendo bem tolerada pelas crianças às quais foram submetidas, podendo constituir uma opção segura para casos graves e difíceis de VKC. Uma melhora significativa foi encontrada nos sinais e sintomas alérgicos oculares, com diminuição da frequência de recidivas agudas, no entanto sem se mostrar efetiva para a completa remissão da doença.

ABSTRACT

ABSTRACT Purpose: To evaluate whether reducing eyelid muscular force through the administration of botulinum toxin type A (BTX-A) to the orbicularis oculi muscles of patients with keratoconus affected corneal parameters indicative of disease progression. Methods: In this prospective parallel randomized clinical trial, 40 eyes of 40 patients with keratoconus were randomized into equally sized control and BTX-A groups. Patients in the BTX-A group received subcutaneous BTX-A injections into the orbicularis muscle. The control group received no intervention. Palpebral fissure height, best spectacle-corrected visual acuity (BSCVA), and corneal topographic parameters were evaluated at baseline and at 3-, 6-, 12-, and 18-month follow-ups. Results: The mean ± standard deviation vertical palpebral fissure heights were 9.74 ± 1.87 mm and 9.45 ± 1.47 mm at baseline in the control and BTX-A groups, respectively, and 10.0 ± 1.49 mm and 9.62 ± 1.73 mm at 18 months, with no significant difference between the groups (p=0.337). BSCVA values were 0.63 ± 0.56 and 0.60 ± 0.27 at baseline in the control and BTX-A groups (p=0.643), and 0.52 ± 0.59 and 0.45 ± 0.26 at 18 months, again with no significant difference between the groups (p=0.452). In addition, there were no statistical differences between the groups at 18 months for the three keratometry topographic parameters: flattest (K1), steepest (K2), and mean (Km) keratometry (p=0.562). Conclusion: BTX-A inhibition of eyelid force generation did not result in detectable changes in corneal parameters in keratoconic patients during 18 months of follow-up.


RESUMO Objetivo: Avaliar se a administração da toxina botulínica tipo A (BTX-A) no músculo orbicular de pacientes com ceratocone a fim de reduzir a força muscular palpebral pode alterar os parâmetros corneanos indicativos de progressão da doença. Métodos: Ensaio clínico randomizado paralelo prospectivo. Quarenta olhos de 40 pacientes, randomizados em grupo controle ou grupo BTX-A na razão de 1:1. Pacientes do grupo BTX-A foram submetidos à injeção subcutânea da toxina botulínica tipo A no músculo orbicular. Os pacientes do grupo controle não sofreram nenhuma intervenção. Foram avaliados a medida da fenda palpebral, melhor acuidade visual corrigida, e topografia corneana nos momentos pré-operatório, e aos 3-,6-,12-, e 18 meses de seguimento. Resultados: Média ± DP (desvio padrão) da fenda palpebral no pré-operatório nos grupos controle e BTX-A foram 9,74 ± 187 e 9,45 ± 1,47 mm, respectivamente; aos 18 meses, a média da altura da fenda palpebral vertical nos grupos controle e BTX-A foram 10,0 ± 1,49 mm e 9,62 ± 1,73 mm, respectivamente, sem diferença significante entre os grupos (p=0,337). A média pré-operatória da melhor acuidade visual corrigida nos grupos controle e BTX-A foram 0,63 ± 0,56 e 0,60 ± 0,27, respectivamente (p=0,643); aos 18 meses, a média nos grupos controle e BTX-A foram 0,52 ± 0,59 e 0,45 ± 0,26, respectivamente, sem diferença significante entre os grupos (p=0,452). Não houve diferença estatística entre os grupos aos 18 meses para todos os parâmetros topográficos ceratométricos avaliados, mais plano-(K1), mais curvo-(K2), e ceratometria média Km (p≥0,562). Conclusão: A inibição da força muscular palpebral pela toxina botulínica tipo A não causou alterações detectáveis nos parâmetros corneanos em pacientes com ceratocone, com 18 meses de seguimento.

ABSTRACT

Purpose: To quantify and compare the effects of instillation with 10% phenylephrine and digital lifting on the contralateral upper eyelid of patients with involutional bilateral blepharoptosis. Methods: The present prospective clinical study involved patients with involutional bilateral blepharoptosis who underwent two tests: 1) digital lifting of the more ptotic eyelid and observation of the effect on the contralateral eyelid and 2) instillation of two drops of 10% phenylephrine in the more ptotic eye and observation of the effect on the contralateral eyelid. Patients were filmed before and 5, 10, and 15 min after instillation, and the resulting images were analyzed to obtain eyelid measurements. The results were tested using a linear mixed-effects model. Results: A total of 27 patients, ranging from 52 to 82 years of age (mean age 68.51 ± 8.21 years), 24 (88.88%) of whom were women, were included in the present study. In eyes that received instillation, the marginal distance reflex-1 (MDR1) values increased from baseline (1.21 ± 0.60 mm) until 10 min after instillation, then remained statistically unchanged until 15 min after instillation (2.42 ± 0.90 mm). Significant differences were observed in the contralateral eye of the group that underwent digital lifting (1.51 ± 0.53 mm - 1.63 ± 0.56 mm) and in the contralateral eye of the group that underwent 10% phenylephrine instillation (1.38 ± 0.54 mm - 1.63 ± 0.56 mm); p=0.02 and p<0.01, respectively. Conclusion: In all eyes, 10% phenylephrine elevated the upper eyelid, with improved eyelid height at 10 min after instillation. Significant differences were observed in the height of the contralateral eyelid when compared before and after each intervention in each group; however, this difference was very small and nearly undetectable by conventional clinical evaluation in the digital lifting group. However, the 10% phenylephrine eye-drop test resulted in substantial changes in MDR1 values ...


Objetivo: Quantificar e comparar o efeito da instilação do colírio de fenilefrina 10% com o levantamento manual da pálpebra superior contralateral de pacientes com ptose palpebral bilateral involucional. Métodos: Estudo clínico e prospectivo de pacientes com ptose palpebral bilateral involucional submetidos a dois testes: 1) elevação manual da pálpebra mais ptótica e observação do efeito da intervenção na pálpebra contralateral; e 2) a instilação de duas gotas de colírio de fenilefrina 10% no olho mais ptótico e observação do efeito da intervenção na pálpebra contralateral. Os pacientes foram filmados antes e 5, 10 e 15 minutos após a instilação. Os resultados foram analisados estatisticamente com o modelo linear de efeitos mistos. Resultados: O estudo incluiu 27 pacientes com idade entre 52-82 anos (68,51 ± 8,21), 24 dos quais eram do sexo feminino (88,88%). Em olhos submetidos a instilação do colírio, os valores da DMR1 (distância marginal reflexo) aumentaram da linha de base (1,21 ± 0,60 mm) até os 10 min, em seguida, manteve-se estatisticamente estável até 15 min (2,42 ± 0,90 mm). Diferenças significativas foram observadas nos olhos contralaterais, independentemente do levantamento manual da pálpebra (1,51 ± 0,53 mm - 1,63 ± 0,56 milímetros) e da instilação do colírio de fenilefrina 10% (1,38 ± 0,54 mm - 1,63 ± 0,56 mm), p=0,02 e p<0,01 respectivamente. Conclusões: Em todos os olhos, a instilação do colírio de fenilefrina 10% mostrou um aumento gradual do valor de distância marginal reflexo até os 10 min. Nos olhos contralaterais houve diminuição do valor de distância marginal reflexo, independentemente do teste realizado, porém as mudanças que ocorrem na posição da pálpebra contralateral, durante o teste da elevação manual, são muito pequenas e difíceis de serem detectadas no exame clínico convencional. Enquanto isso, o teste de colírio de fenilefrina 10% produziu mudanças substanciais nos valores distância marginal reflexo nos ...

ABSTRACT

Objective: To evaluate in experimental animals the changes of the palpebral fissure and the orbital volume after orbital injection of bimatoprost 0.03%. Methods: Two main groups of Wistar rats were analyzed, one after orbital injection of bimatoprost 0.03% and another, a control group, after orbital injection of saline solution. The calculation of the palpebral fissure was done on images by means of computer processing, using the program Image J. After taking photographs, the animals were submitted to bilateral orbital exenteration and the volume was calculated in all the animals by the water displacement method (Archimedes’ Principle). Results: While comparing the measurements of the palpebral fissure and the orbital volume among animals given an injection with bimatoprost 0.03% and the control group it was found that there were no statistically significant differences. Conclusions: In this study there were no statistically significant differences in the measurement of the vertical palpebral fissure and the orbital volume among animals given the orbital injection of bimatoprost 0.03% and the animals of the control group. .


Objetivo: Avaliar em modelos experimentais as alterações da fenda palpebral e do volume orbitário após aplicação orbitária de bimatoprost 0,03%. Métodos: Dois principais grupos compostos por ratos Wistar foram analisados, sendo comparados os animais submetidos à injeção orbitária de bimatoprost 0.03% com os submetidos à injeção orbitária de solução salina. O cálculo da fenda palpebral vertical foi obtido através de imagem computadorizada utilizando-se o programa Image J. Após serem fotografados os animais foram submetidos à exenteração bilateral e o volume orbitário foi calculado pelo método de deslocamento da coluna de água (Princípio de Archimedes). Resultados: Quando foram comparadas as medidas da fenda palpebral vertical e do volume orbitário entre os animais submetidos a injeção de bimatoprost 0.03% e o grupo controle não foi obsevada diferença estatisticamente significante. Conclusão: Neste estudo não houve diferença estatisticamente significante nas medidas da fenda palpebral vertical e no volume orbitário entre os animais submetidos à injeção orbitária de bimatoprost 0.03% e o grupo controle. .

ABSTRACT

OBJETIVO: Verificar a eficácia do preenchimento dos sulcos nasojugal e palpebromalar deprimidos através da injeção de ácido hialurônico e analisar as complicações observadas. MÉTODOS: Foi realizado um estudo piloto, prospectivo, aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de São Paulo, com pacientes recrutados no Serviço de Plástica Ocular do Departamento de Oftalmologia da UNIFESP/EPM. Foram selecionados pacientes de ambos os sexos, com idade entre 25 e 60 anos, que apresentavam os sulcos nasojugal e/ou palpebromalar deprimidos, que não haviam sido submetidos à cirurgia na pálpebra inferior nem apresentavam histórico de trauma nesse local. O ácido hialurônico foi aplicado via transcutânea e depositado na região supraperiosteal em pequenos volumes. Todo paciente foi tratado pelo mesmo cirurgião (GAPV), tendo sido examinado no pós-operatório em intervalos regulares e fotografado no pré-operatório, no pós-operatório imediato, na 4ª semana, no 6º e no 12º mês após o procedimento. Ao final deste período todas as fotos foram analisadas por profissional não ligado a esta pesquisa, visando verificar a eficiência da técnica em atingir seus objetivos. RESULTADOS: Entre junho e agosto de 2008, 10 pacientes foram incluídos neste estudo piloto. Oito pacientes foram tratadas uma única vez, enquanto duas precisaram de retoque na 4ª semana após a aplicação inicial. O volume injetado foi em média de 0,61 ml (DP=0,25) no lado direito e de 0,65 ml (DP=0,26) no lado esquerdo. As complicações observadas foram equimose em 6 casos, edema local maior que 48 horas em um paciente e lesão cutânea semelhante à acne em um participante. CONCLUSÕES: O estudo piloto demonstrou que o tratamento dos sulcos nasojugal e pálpebro-malar com uso de ácido hialurônico se mostrou eficaz e previsível, com alto nível de satisfação dos pacientes e com resultado duradouro.


BACKGROUND: Volume loss and muscular hyperactivity are two major components of the aging process that contribute to the formation of the folds and wrinkles. Tear trough deformity is one of the most difficult depressions to correct surgically. PURPOSE: The aim of this study was to evaluate the results of ten patients submitted to periorbital filling with hyaluronic acid gel filler. METHODS: Between June and August, 2008, 10 patients have had their tears troughs treated with hyaluronic acid gel filler. The filler was introduced by a serial puncture technique and approximately 0.1 ml was injected at each pass. The filler was placed in the pre-periosteal tissue. Patients photographs before and after the procedure were reviewed to assess the outcomes. RESULTS: The mean volume per side needed to achieve correction was on the right side 0.61 ml (SD=0.25) and on the left side 0.65 ml (SD=0.26). The most common complications were bruising, erythema, local swelling, and pain at the injection site. The effect of treatment lasted up to 12 months. CONCLUSIONS: This pilot study showed that the treatment of tear trough deformity with hyaluronic acid gel filler was feasible, predictable and effective. All patients were very satisfied with their results.

ABSTRACT

OBJETIVOS: Determinar a ação de uma gota do colírio de fenilefrina 10 por cento sobre as pálpebras superior e inferior de indivíduos normais; verificar a ocorrência de alterações no posicionamento das pálpebras superior e inferior do olho contralateral, após instilação desta medicação. MÉTODOS: Estudo prospectivo observacional, do qual participaram 24 indivíduos normais, com idade entre 20 e 39 anos, submetidos à instilação de uma gota do colírio de fenilefrina 10 por cento no fundo de saco conjuntival superior, aleatoriamente em um dos olhos. Todos os indivíduos foram filmados antes e após a instilação do colírio (3, 10, 15, 30, 45 e 60 minutos). As imagens foram submetidas ao processamento digital e editadas para análise das medidas palpebrais. Foi traçada uma linha horizontal do canto medial até o canto externo. Considerou-se a altura da pálpebra superior a distância entre o ponto mais alto da margem palpebral superior e a linha horizontal traçada. A altura palpebral inferior foi avaliada como a distância entre o ponto mais baixo da margem palpebral inferior e a referida linha. RESULTADOS: Em relação à pálpebra superior, a medida antes da instilação da fenilefrina 10 por cento diferiu significativamente dos demais momentos (p<0,001) com elevação média da pálpebra superior de 0,79 mm e retração de 0,37 mm na altura palpebral inferior. Em relação ao olho contralateral, observou-se queda da pálpebra superior em praticamente todos os momentos estudados, com o menor nível aos 3 minutos (queda média de 0,68 mm). A pálpebra inferior contralateral mostrou elevação média de 0,37 mm. CONCLUSÕES: A instilação de uma gota do colírio de fenilefrina 10 por cento em olhos de indivíduos normais altera a posição da pálpebra superior do olho testado, assim como a da pálpebra inferior. O posicionamento da pálpebra superior e inferior do olho contralateral também se alteram.


PURPOSE: To determine the upper and lower eyelid position with a single drop of 10 percent phenylephrine in normal individuals and observe positional lid changes in upper and lower lids of the opposite eye. METHODS: Prospective observational study including 24 healthy subjects of both genders (age range: 20-39 yrs) submitted to instillation of a single drop of 10 percent phenylephrine in the upper fornix of one randomly chosen eye. A video camera recorded the images of both eyes before and after eye drop application at 3, 10, 15, 30, 45 and 60 minutes. The images were digitally processed and edited to analyze lid measurements (upper lid height: distance between the highest upper margin lid point and a horizontal line traced from the medial to the lateral canthus; lower lid height: distance between the lowest margin lid point and the above-mentioned line). RESULTS: Before and after drug instillation, upper lid height was significantly different (p<0.001) at all moments with a mean elevation of 0.79 mm. The lower lid height changed too with a mean retraction of 0.37 mm. In the fellow eye upper lid drop was observed at almost all moments with the lowest value at 3 minutes (mean reduction of 0.68 mm) and elevation (0.37 mm) of lower lid. CONCLUSIONS: This experiment showed that a single drop of 10 percent phenylephrine acted not only on the upper eyelid but also on lower lid of the tested eye. Control mechanism of lid opening and closing changed upper and lower lid positioning of the opposite eye in healthy subjects.

ABSTRACT

Vernal keratoconjunctivitis [VKC] cases are sometimes resistant to conventional treatments. We aimed to assess the efficacy, safety and longevity of the effect of supratarsal injection of intermediate acting steroid triamcinolone acetonide in the management of recalcitrant vernal keratoconjunctivitis. A prospective study comprising of Forty five patients [90 eyes] with severe VKC, and resistant to conventional method of treatments were selected and underwent injection of 0.6 ml triamcinolone acetonide in supratarsal area [in conjunctival side of upper lid] and were followed up for 12 months. Dramatic relief of symptoms [burning, itching, lacrimation and photophobia, tenacious discharge] was seen in all patients, in first few days after the supratarsal injection. Size of the cobble stone papillary hypertrophy in tarsal conjunctiva, gelatinous thickening of conjunctiva at limbus decreased significantly in the first month, but never disappeared completely. The mean period of recurrence of symptoms was 156.6 days [range 13-359 days]. No complication was noticed during the follow up period. All patients tolerated the treatment well. Supra tarsal injection of triamcinolone acetonide is a cheap, effective and safe modality for temporary suppression of clinical signs and symptoms of eyes with recalcitrant vernal keratoconjunctivitis. Rapid and dramatic symptomatic and clinical response and lack of complications suggest that supratarsal injection of triamcinolone acetonide could be a therapeutic approach for refractory vernal keratoconjunctivitis

ABSTRACT

To determine if the involuntary contractions of eyelids may have any effects on the development of corneal astigmatism, we performed this prospective study which includes 19 patients with either essential blepharospasm or hemifacial spasm. In hemifacial spasm, the degree of corneal astigmatism was evaluated between two eyes. Then the topographic changes were checked using vector analysis technique before and after passively opening the eyelids. They were also measured before and at 1 and 6 months after the injection of Botulinum toxin. Resultantly, 20 eyes had the with-the-rule (group1) and 9 eyes against-the-rule (group2) astigmatism. In hemifacial spasm, significantly more astigmatism was found at spastic eyes. The corneal topographic changes after passively opening the eyelids showed 10 eyes with the astigmatic shift to the with-the-rule, while the remaining 19 to the againstthe- rule. At 1 month after injection of Botulinum toxin, group 1 showed reduced average corneal astigmatism, whereas group 2 showed increased astigmatism. The astigmatic change vector showed significantly more against-the-rule. In the contrary, 6 months after treatment, corneal astigmatism again increased in group 1 and decreased in group 2. So they took on the appearance of pretreatment astigmatic status eventually. Conclusively eyelids may play an important role in corneal curvature.

ABSTRACT

Six patients with upper eyelid retraction due to dysthyroidism at Siriraj Hospital received subcutaneous botulinum toxin treatment at a dosage of 5-20 units per injection. Five patients experienced an improvement in the lid retraction lasting at least 40 months and 3 patients required more than one injection. Botulinum toxin injection is an alternative treatment for the upper eyelid retraction of dysthyroidism, which is effective and causes minimal side effects, particularly in patients with euthyroid status.
