ABSTRACT

Abstract Sporotrichosis is a subcutaneous mycosis that affects humans and animals, with a typically subacute or chronic evolution, caused by Sporothrix spp., a dimorphic fungus. Although the cutaneous form is the most frequent presentation, the ocular involvement has been more frequently diagnosed in endemic areas, affecting mainly children and the elderly. Approximately 80% of affected patients have the lymphocutaneous form, while only 2.3% have conjunctival lesions, with 0.7% showing primary ocular involvement. We describe two cases of sporotrichosis with ocular involvement in children through inoculation by felines, with a good response to antifungal treatment.

ABSTRACT

It is widely acknowledged that holistic processing is a key characteristic of face perception. Although holistic processing implies the automatic integration of face parts, it is unclear whether such processing requires the awareness of face parts. Here, we investigated the interactions between visible face parts and face parts rendered invisible using continuous flash suppression (CFS). In the first experiment with the upper half-face visible and the lower half-face invisible, the results showed that perceived face identity was influenced by the invisible lower half-face, suggesting that integration occurs between the visible and invisible face parts, a variant of the "composite face effect". In the second experiment, we investigated the influence of visible face parts on the processing of invisible face parts, as measured by the time it took for the invisible parts to break out from CFS. The results showed a visible-to-invisible facilitation effect, that the aligned invisible face parts broke through CFS faster than when the visible and invisible face parts were misaligned. Visible eyes had a stronger influence on the invisible nose/mouth than the other way around. Such facilitation of processing from visible to invisible parts was also found when Chinese characters were used as stimuli. These results show that information integration occurs across the consciousness boundary.

ABSTRACT

ABSTRACT Introduction: The SARS-CoV-2 pandemic has been a major challenge for the international scientific community. Since its inception, studies aiming to describe pathophysiological aspects and clinical manifestations of the disease have been conducted, raising hypotheses and confirming possible associations. One aspect of this scientific medical production is the role of the ocular surface as a means of transmission and clinical presentation of viral syndrome. Objectives: To analyze the role of the ocular surface in transmission, pathophysiology, and clinical manifestations of SARS-CoV-2, by means of a systematic review. Methods: The search was carried out in three databases: Cochrane, PubMed Central Journals and MEDLINE, using the following descriptors: "COVID-19, ophthalmology". The filters last five years and studies on humans resulted in 32 studies; in that 12 were excluded for not meeting the purpose of the study. Results: There are still few published studies on the relation between SARS-CoV-2 and the ocular route. Most studies showed an association between the presence of nonspecific ocular manifestations and infection by the new coronavirus, with limitations in the number of patients analyzed and the methodology adopted. Hypotheses about the pathophysiological role are largely anchored in the association of SARS-CoV and the ocular surface evaluated in the past. Comments: The results found are still not sufficient to confirm the role of the ocular surface in the pathophysiology of the disease. Most of these preliminary studies are of considerable importance in raising hypotheses based on the medical analysis of the patients studied. However, larger studies with standardized methodology for diagnostic protocol and laboratory analysis of the individuals assessed are required.


RESUMO Introdução: A pandemia da SARS-CoV-2 tem sido um grande desafio para a comunidade científica internacional. Desde seu surgimento, estudos com a intenção de descrever os aspectos fisiopatológicos e as manifestações clínicas da doença vêm sendo conduzidos, levantando hipóteses e confirmando possíveis associações. Um dos temas dessa produção médica científica é o papel da superfície ocular como meio de transmissão e apresentação clínica da síndrome viral. Objetivo: Analisar o papel da superfície ocular na transmissão, na fisiopatologia e nas manifestações clínicas de SARS-CoV-2, através de uma revisão sistemática. Realizou-se a busca em três bancos de dados Cochrane Database, PubMed® e MEDLINE®, utilizando os descritores "COVID-19 e ophthalmology". Foram definidos como filtros o artigo ter sido publicado nos últimos 5 anos e estudo realizado em humanos, tendo sido encontrados 32 artigos. Destes, foram excluídos 12 por não corresponderem ao objetivo do estudo. Resultados: Ainda são poucos os estudos publicados sobre a relação entre o coronavírus 2 da síndrome respiratória aguda grave (SARS-CoV-2) e a via ocular. A maioria dos estudos mostrou associação entre a presença de manifestações oculares inespecíficas e a infecção pelo novo coronavírus, com limitações no número de pacientes analisados e na metodologia adotada. Hipóteses sobre o papel fisiopatológico se ancoram, em grande parte, na associação estudada entre o SARS-CoV-2 e a superfície ocular no passado. Comentários: Os resultados encontrados ainda não são suficientes para confirmar o papel da superfície ocular na fisiopatologia da doença. Grande parte desses estudos preliminares têm importância considerável ao levantar hipóteses baseadas na análise clínica dos pacientes estudados. No entanto, são necessários estudos maiores e com metodologia padronizada para protocolo diagnóstico e análise laboratorial dos indivíduos avaliados.

ABSTRACT

RESUMEN Introducción: El síndrome de Sjögren es una enfermedad autoinmune asociada a múltiples factores, tanto genéticos como ambientales, que afecta principalmente a las glándulas salivales y lagrimales con infiltración celular de estas, lo cual causa síntomas secos. Con frecuencia se describe la queratoconjuntivitis sicca y sus complicaciones. Sus criterios clasificatorios han cambiado a lo largo de los años por la diversidad de los órganos implicados y los espectros clínicos de la enfermedad. Hoy se cuenta con parámetros clínicos y paraclínicos para su identificación; uno de estos, el puntaje de tinción ocular ocular staining score (OSS, por sus siglas en inglés), estandarizado a partir de la cohorte SICCA. Objetivo: Describir los hallazgos en la evaluación ocular, el resultado de las pruebas que hacen parte del OSS y las características clínicas de los criterios clasificatorios en pacientes con síndrome de Sjögren en el servicio de consulta externa de reumatología de un hospital universitario en el noroccidente colombiano. Método: Se condujo un estudio observacional, descriptivo y de corte transversal. Se describieron las características de los criterios clasificatorios del síndrome de Sjögren, incluyendo el puntaje de tinción ocular durante un año. Se realizaron las pruebas clínicas y tinciones oculares estandarizadas, evaluando características de la superficie ocular, producción lagrimal y tinciones con verde lisamina y fluoresceína sobre la conjuntiva y la córnea. Según los hallazgos se asignó una puntuación a cada parámetro para evaluar positividad, de acuerdo con el estándar clasificatorio. Las variables cualitativas se expresaron por medio de frecuencias absolutas y relativas y las cuantitativas como mediana y rango intercuartílico (P25-P75), según la distribución de los datos. Se empleó el paquete estadístico Epidat, versión 4.2. Resultados: Se incluyeron 28 pacientes. Los síntomas de ojo seco estuvieron presentes en el 89,2% de ellos; un 96,4% tuvo hallazgos positivos en el examen ocular y el 78,5% alcanzó un puntaje a favor de los criterios clasificatorios en la evaluación del OSS. La mediana del OSS fue 6,14; los anticuerpos anti-Ro fueron positivos en un 57,1%. Conclusión: La evaluación ocular por medio de pruebas objetivas es un método sencillo y reproducible en los pacientes con síndrome de Sjögren. Los índices más afectados fueron aquellos de disminución en la producción lagrimal. Las tinciones oculares no tuvieron una relación directa con la positivad de anticuerpos ni del factor reumatoide.


ABSTRACT Introduction: Sjögren's syndrome is an autoimmune disease associated with multiple genetic and environmental factors. It mainly affects the salivary and lacrimal glands with cellular infiltration leading to dry eye symptoms, with keratoconjunctivitis sicca and its complications often being described. Its classification criteria have changed over the years, due to the diversity in the organs involved and clinical spectrum of the disease. Today, there are clinical and para-clinical parameters for its identification. One of these is the ocular staining score (OSS), standardised from the SICCA cohort. Objective: To describe the findings in the ocular evaluation, the results of the tests of the OSS, and the clinical characteristics of the classification criteria in patients with Sjögren syndrome in the outpatient service of Rheumatology Outpatient Department a university hospital in north-western Colombia. Methods: An observational, descriptive, cross-sectional study was conducted. The characteristics of the Sjögren syndrome classification criteria were described, including the OSS score for one year. Clinical tests and standardised ocular stains were performed, evaluating characteristics of the ocular surface, tearproduction, and lissamine green and fluorescein stains on the conjunctiva and cornea, assigning, according to the findings, a score to each parameter in order to assess positivity according to the classification standard. The qualitative variables were expressed by means of absolute and relative frequencies, and the quantitative ones as the median and interquartile range (P25-P75), according to the distribution of the data. Epidat statistical package, version 4.2, was used. Results: A total of 28 patients were included. Dry eye symptoms were present in 89.2%, 96.4% had positive findings in the eye examination, and 78.5% had a score on the OSS according to the classification criteria. The median OSS was 6.14, and anti-Ro antibodies were positive in 57.1%. Conclusion: Eye evaluation by objective tests is a simple and reproducible method in patients with Sjögren's syndrome. The most affected indices were those of a decrease in tearproduction. The ocular stains did not have a direct relationship with the positivity of antibodies, nor rheumatoid factor.

ABSTRACT

INTRODUCCIÓN: el trauma ocular es una de las causas que difieren entre áreas urbanas de un país a otro y entre diferentes clases demográficas o socioeconómicas. OBJETIVO: Demostrar la evolución y características clínicas del edema de Berlín secundario a trauma ocular cerrado. MATERIALES Y MÉTODOS: se realizó un estudio de caso observacional en un paciente masculino de 11 años que presentó una AVMC 20/20 en OD y cuenta dedos 50 cm en OI posterior a trauma ocular cerrado contuso con objeto romo. Desde el inicio desarrolló una conmoción retiniana asociada a edema de Berlín en OI. Con seguimiento desde 11 de diciembre de 2019 al 27 de enero de 2020. Las variables fueron: agudeza visual mejor corregida, retinografía, tomografía de coherencia óptica de dominio espectral macular. RESULTADOS: se indicó metilprednisolona 500 mg endovenoso diario por 3 días; prednisona 30 mg oral disminuyendo gradualmente durante 10 días; acetato de prednisolona 1% tópico cada 2 horas, moxifloxacina 0,5% cada 6 horas, ciclopentolato 1% cada 8 horas. 7 semanas después, no hubo mejoría clínica a pesar de medicación, manteniéndose en observación médica con AVMC OD 20/20 y OI cuenta dedos 2 metros. DISCUSIÓN: edema de Berlín (commotio retinae) una afección común causada por una lesión contusa en el ojo, suele ser autolimitante y no existe un tratamiento como tal. CONCLUSIÓN: el trauma ocular cerrado contuso con compromiso retiniano puede causar daño macular como el edema de Berlín, como éste caso que puede condicionar el pronóstico visual a pesar de que mayormente es favorable.


INTRODUCTION: ocular trauma is one of the causes that differ between urban areas from one country to another and between different demographic or socioeconomic classes. OBJECTIVE: to demonstrate the evolution and clinical characteristics of Berlin edema secondary to closed ocular trauma. MATERIALS AND METHODS: an observational case study was conducted in an 11-year-old male patient who presented a 20/20 BCVA in RE and 50 cm finger count in LE after blunt ocular trauma with blunt object. From the beginning, she developed a retinal concussion associated with Berlin edema in LE. With follow-up from December 11, 2019 to January 27, 2020. Variables were included: best-corrected visual acuity, retinographies, and macular spectral domain optical coherence tomography. RESULTS: methylprednisolone 500 mg intravenous daily for 3 days was indicated; prednisone 30 mg oral gradually decreasing over 10 days; 1% prednisolone acetate topical every 2 hours, moxifloxacin 0.5% every 6 hours, cyclopentolate 1% every 8 hours. 7 weeks later, there was no clinical improvement despite medication, and he was kept under medical observation with BCVA RE 20/20 and LE with a 2-meter finger count. DISCUSSION: Berlin edema (commotio retinae), a common condition caused by a blunt injury to the eye, is usually self-limiting and there is no treatment as such. CONCLUSION: blunt ocular trauma with retinal involvement can cause macular damage such as Berlin edema, as in this case, which can condition the visual prognosis even though it is mostly favorable.

ABSTRACT

El tratamiento quirúrgico del pterigión es uno de los procedimientos más realizados en la consulta oftalmológica, aunque con frecuencia conlleva molestias y cambios en la agudeza visual. OBJETIVO: evidenciar si existen cambios en cuanto a agudeza visual y su ametropía, en pacientes diagnosticados con pterigión intervenidos quirúrgicamente, en la ciudad de Quito. METODO: se trata de un estudio observacional longitudinal que incluyó 161 pacientes. Se comparó agudeza visual y ametropía antes y 15 días después de la intervención quirúrgica. RESULTADOS: la mayor parte de los pacientes fue de género femenino (n = 118, 73%) tuvo entre 30 y 59 años (n = 127, 79%), presentó pterigión grado III (n = 113, 70%) y fue intervenido del ojo derecho (n = 89, 55%). La agudeza visual de los pacientes mejoró ligeramente. El número de pacientes con agudeza visual 20/20 aumentó de 68 (42%) a 72 (45%). Se observó además una disminución en el número de pacientes con agudeza visual 20/350, 20/200, 20/100, 20/80, 20/60 y 20/50. No hubo cambios en el número de pacientes amétropes que se mantuvo en 69 (43%). Tanto el número de personas con astigmatismo miópico compuesto, como con astigmatismo mixto eje contra la regla disminuyeron de 11 (7%) a 8 (5%) y de 24 (15%) a 16 (10%), respectivamente. CONCLUSIÓN: tanto la agudeza visual como la ametropía de pacientes con pterigión mejoran ligeramente después de recibir tratamiento quirúrgico.


The surgical treatment of the pterygium is one of the most performed procedures in the ophthalmologic consultation, although it often involves discomfort and changes in visual acuity. OBJECTIVE: to show if there are changes in visual acuity and its ametropia, in patients diagnosed with surgically intervened pterygium, in the city of Quito. METHOD: This is a longitudinal observational study that included 161 patients. Visual acuity and ametropia were compared before and 15 days after surgery. RESULTS: most of the patients were female (n = 118, 73%), were between 30 and 59 years old (n = 127, 79%), presented grade III pterygium (n = 113, 70%) and was operated on the right eye (n = 89, 55%). The visual acuity of the patients improved slightly. The number of patients with visual acuity 20/20 increased from 68 (42%) to 72 (45%). There was also a decrease in the number of patients with visual acuity 20/350, 20/200, 20/100, 20/80, 20/60 and 20/50. There were no changes in the number of ametropic patients that remained in 69 (43%). Both the number of people with compound myopic astigmatism, and with mixed astigmatism axis against the rule decreased from 11 (7%) to 8 (5%) and from 24 (15%) to 16 (10%), respectively. CONCLUSION: both visual acuity and ametropia of patients with pterygium improve slightly after receiving surgical treatment.

ABSTRACT

SUMMARY: Frontaly and anteriorly the orbit is closed by a skin-muscular closure of eyelids. The eyelids limit the palpebral fissure, which is subject to geographical, racial, and age variations. As a part of the face, eyelids and palpebral fissure play a very important role in the attractiveness of the individual, but al so in the diagnosis of certain local and systemic pathological processes. The aim of the study was to perform a morphometric analysis of the palpebral fissure in a young population without pathological conditions and syndromes. The study was conducted on 90 subjects (45 male and 45 female) aged 19.28±0.69 years. Subjects were photographed with a Nikon D3400 camera, and the morphometric parameters were measured with the ImageJ 1.48v software. Statistical analysis of the data was performed in Windows Excel. The measurements in the study were the distance between the mid-points of both pupils, distance between both external canthi, distance between both internal canthi, palpebral fissure width and palpebral fissure height at three points. The average height of the palpebral fissure to the right is 9.35±1.55 mm and to the left is 9.41±1.56 mm. The average width of the palpebral fissure on the right is 27.05±1.71 mm and on the left is 27.18±1.68 mm. It was found that there was some difference in the measured parameters, however, this difference was not statistically significant.


RESUMEN: El músculo orbicular de los ojos se encuentra en la cara, delante de la órbita y debajo de la piel. Los párpados limitan la fisura palpebral, la abertura natural, sujeta a variaciones geográficas, raciales y de edad. Los párpados y la fisura palpebral juegan un papel importante en la estética de las personas, pero también en el diagnóstico de ciertos procesos patológicos locales y sistémicos. El objetivo del estudio fue realizar un análisis morfométrico de la fisura palpebral en una población joven sin enfermedades o condiciones patológicas. El estudio se realizó en 90 sujetos (45 hombres y 45 mujeres) de 19,28 ± 0,69 años. Los sujetos fueron fotografiados con una cámara Nikon D3400, y los parámetros morfométricos se midieron con el software ImageJ 1.48v. El análisis estadístico de los datos se realizó en Windows Excel. Se midieron la distancia entre los puntos medios de ambas pupilas, la distancia entre ambos cantos laterales, la distancia entre ambos cantos mediales, el ancho de la fisura palpebral y la altura de la fisura palpebral en tres puntos. La altura promedio de la fisura palpebral a la derecha fue 9,35 ± 1,55 mm y a la izquierda fue 9,41 ± 1,56 mm. El ancho promedio de la fisura palpebral a la derecha era 27,05 ± 1,71 mm y a la izquierda era 27,18 ± 1,68 mm. Se determinó una diferencia leve en los parámetros medidos, sin embargo, esta diferencia no fue estadísticamente significativa.

ABSTRACT

The field related to the visual system of wild animals is deeply scarce. Settling anatomical and physiological parameters for these animals is still a descriptive vision for Bradypus variegatus (Schinz, 1825). Thus, our research aimed to determine patterns of normal eye for this species. For this purpose, eight eye bulbs were dissected from the carcasses obtained by natural death, and then performed an overview of ocular anatomical. Rebound tonometry (RBT) and ocular B-mode ultrasonography were also applied for eight eyes in four animals from "Parque Estadual Dois Irmãos", situated in the city of Recife, state of Pernambuco (PE), to estimate the intraocular pressure and ocular ecobiometry. The ocular morphology of sloth is similar as described for other species, however, with some peculiarities. They present a third eyelid emerging in the nasal region of the inferior conjunctival sac and retina and also contain little differentiated blood vessels. Medium the intraocular pressure (IOP) was 4.25mmHg with no difference for both eyes. Ultrasonography of ocular anatomy is also similar regarding other species. Ecobiometric patterns were evaluated to determine the anterior chamber depth, lens width, vitreous chamber depth, and axial length (AL) of ocular globe and the averaged as shown 0.63±1.11mm, 3.73±0.24mm, 6.15±0.41mm, 3.70±0.27mm, and 8.48±0.22mm, respectively. There was no difference between the right and left eyes. The RBT and ocular B-mode ultrasonography are fast exams and easy for animal testing. This study contributed to the characterization of ocular anatomy as well as settling medium values of IOP and intraocular measures; however, further research on physiology and histology is necessary to better understand the visual function of the species.(AU)


O campo de estudo relacionado ao sistema visual de animais silvestres é muito escasso. Estabelecer parâmetros anatômicos e fisiológicos para estes animais ainda está restrito a uma visão descritiva, assim ocorre em Bradypus variegatus (Schinz, 1825). Diante deste fato, objetivou-se com este estudo determinar padrões de normalidade oftálmica nesta espécie. Para isto foram dissecados oito bulbos oculares de cadáveres obtidos por morte natural e realizada a descrição anatômica ocular. Além disso, foram realizadas tonometria de rebote (TonoVet®) e ultrassonografia em modo B em oito olhos de quatro animais provenientes do Parque Estadual Dois Irmãos, Recife/PE, para avaliação da pressão intraocular e realização da ecobiometria ocular. A anatomia ocular do bicho-preguiça é semelhante à descrita para outras espécies com algumas particularidades. Apresentam uma terceira pálpebra emergindo na região nasal do saco conjuntival inferior e retina com vasos sanguíneos pouco diferenciados. A pressão intraocular média foi de 4,25mmHg não havendo diferença entre os olhos direito e esquerdo. A anatomia ocular ultrassonográfica é semelhante à encontrada para outras espécies. Os padrões ecobiométricos obtidos foram: profundidade da câmara anterior, espessura do cristalino, diâmetro do cristalino, profundidade da câmara vítrea e comprimento axial do bubo ocular com tamanhos médios de 0,63±1,11mm, 3,73±0,24mm, 6,15±0,41mm, 3,70±0,27mm e 8,48±0,22mm, respectivamente. Não houve diferença entre os olhos direito e esquerdo. A tonometria de rebote e a ultrassonografia ocular em modo B são exames de rápida e fácil execução, sendo bem tolerados pelos animais. Este estudo contribuiu para a caracterização anatômica ocular e para o estabelecimento de valores médios da pressão intraocular e das medidas intraoculares, no entanto são necessárias outras pesquisas na área da fisiologia e histologia para melhor compreensão da função visual da espécie.(AU)

ABSTRACT

Resumen La endoftalmitis endógena es responsable del 2-15 % de las endoftalmitis, se relaciona con una infección sistémica hasta en un 52-90% de los casos, en el contexto de infecciones sistémicas como abscesos hepáticos, neumonia, infecciones de vias urinarias, meningitis, usurios de drogas endovenosas y fungémias. Haemophilus influenzae es un agente etiológico inusual de esta patología, hay pocos casos reportados a nivel mundial y no se han reportado casos en nuestro país; las endoftalmitis por Haemophilus se caractererizan por tener un pronóstico visual sombrio, ya que pueden presentar complicaciones severas y comprometer permanentemente la visión. A continuación, se describe un caso de endoftalmitis endogéna como primera manifestación de meningitis asociada a H. Influenzae en una paciente inmunocompetente y sin factores de riesgo.


Abstract Endogenous endophthalmitis is responsible for 2-15% of endophthalmitis, it is associated with a systemic infection in up to 52-90% of cases, in the context of systemic infections such as liver abscesses, pneumonia, urinary tract infections, meningitis, intravenousdrug users and fungaemia. Haemophilus influenzae is an unusual etiologic agent of this pathology, there are few cases reported worldwide and no cases have been reported in our country. The endophthalmitis due to Haemophilus are characterized by having a somber visual prognosis, since they can present severe complications and can permanently affect vision. Mentioned hereinafter, a case of endogenous endophthalmitis is described as the first manifestation of meningitis associated with H.Influenzae in an immunocompetent patient with no risk factors.

ABSTRACT

RESUMEN La granulomatosis con poliangeítis (Wegener) es considerada como una enfermedad granulomatosa sistémica, no infecciosa, caracterizada histológicamente por una vasculitis necrosante de pequeño vaso. El tracto respiratorio superior e inferior son los más frecuentemente afectados, en asociación a manifestaciones renales. Sin embargo, también se describe el compromiso aislado de un solo órgano, como es el caso del globo ocular y la órbita. Presentamos el caso de una mujer cuya principal manifestación consistió en un proceso inflamatorio de tejido periorbitario y proptosis del globo ocular izquierdo. La paciente fue valorada en manejo conjunto con el servicio de plástica ocular, otorrinolaringología y finalmente se derivó a reumatología para inicio de terapia inmunosupresora. Se realizó una revisión de la literatura, en búsqueda de reportes de caso y series de caso que permitieran comparar las presentaciones clínicas y desenlaces más frecuentes.


A B S T R A C T Granulomatosis with polyangiitis (Wegener) is considered as a systemic, non-infectious granulomatous disease, histologically noted for its small vessel necrotising vasculitis. The upper and lower respiratory tracts are the most frequently affected, in association with renal manifestations. However, the isolated involvement of a single organ, such as the eyeball and the orbit is also described. The case is presented of a woman whose main manifestation was an inflammatory process of periorbital tissue and proptosis of the left eyeball. The patient was evaluated jointly with eye plastic surgery, and the ear, nose and throat, and rheumatology departments. A literature review was carried out, looking for case reports and case series that allowed comparisons to made between the clinical manifestations and the most frequent outcomes.

ABSTRACT

ABSTRACT Purpose: To compare the impact of ocular changes between systemic treatment with doxycycline and low-dose oral isotretinoin in patients with moderate-to-severe papulopustular rosacea. Methods: Patients were randomized to receive either isotretinoin 0.3-0.4 mg/kg (group A) or doxycycline 100 mg/day (group B) for 16 weeks. Ocular symptoms were searched and evaluated, including best-corrected visual acuity (BCVA), Schirmer test, breakup time, rose bengal staining score, and meibomian gland dysfunction grading. The patients were retested at the end of treatment. Results: The present study included 39 patients (30 females and 9 males). Best-corrected visual acuity was > 20/30 in >90% of patients in both groups and did not change after treatment. After treatment, improvement in ocular symptoms and meibomian gland dysfunction was more pronounced in group B (p<0.05); the other parameters did not reach statistical significance. Conclusion: Doxycycline improved meibomian gland dysfunction, ocular symptoms, and ocular surface in patients with rosacea. Even though some patients experienced worsening meibomian gland dysfunction and symptoms, no subject experienced any serious complications after administration of low-dose isotretinoin.


RESUMO Objetivos: Comparar o impacto das alterações oculares entre o tratamento sistêmico de doxiciclina e isotretinoína em baixa dosagem em pacientes com rosácea papulopustulosa moderada a grave. Métodos: Os pacientes form randomizados para receber isotretinoína 0,3 a 0,4 mg/kg (grupo A) ou doxiciclina 100mg/dia (grupo B) por 16 semanas. Os sintomas oculares foram pesquisados e avaliados, incluindo melhor acuidade visual corrigida, teste de Schirmer, tempo de ruptura do filme lacrimal, coloração de rosa bengala e graduação da disfunção de glândula de Meibomius. Os pacientes foram novamente testados no final do tratamento. Resultados: O presente estudo incluiu 39 pacientes (30 mulheres e 9 homens). A melhor acuidade visual corrigida foi >20/30 em >90% dos pacientes em ambos os grupos e não se alterou após o tratamento. A melhora dos sintomas oculares e da disfunção de glândula de Meibomius foi mais pronunciada no grupo B (p<0,05) após o tratamento; as demais variáveis não atingiram significância estatística. Conclusão: A doxiciclina melhorou a disfunção de glândula de Meibomius, os sintomas oculares e a superfície ocular de pa cientes com rosácea. Mesmo que alguns pacientes tenham piorado a disfunção e os sintomas da glândula de Meibomius, nenhum indivíduo apresentou complicações graves após a admi nistração de baixas doses de isotretinoína.

ABSTRACT

@#OBJECTIVE: This study aimed to calculate and compare the costs of different brands of ocular hypotensive eye drops available in the Philippines. METHODS: This was a single-center research conducted at a local laboratory. Triplicate samples of 21 different brands of locally-available ocular hypotensive drops were tested. The mass of ten drops, total usable mass, number of drops per bottle, and mass of 200-µL aliquots were measured for each sample. These were used to calculate for the total usable bottle volume, drop volume, and number of drops per milliliter of each sample. Lastly, the daily, monthly, and annual costs were computed and compared. RESULTS: Available brands of β-blockers were the most affordable options for topical glaucoma therapy, with costs ranging from Php1,838 to 8,472 per year. Innovator brands of α-agonists and carbonic anhydrase inhibitors were the most expensive, with annual costs ranging from Php7,641 to 24,295 and Php7,361 to 25,327, respectively. Fixed-combination preparations, with yearly costs ranging from Php4,307 to 22,200, were generally more costeffective than individual preparations. The cost of topical anti-glaucoma therapy can amount up to 3.3 to 66.9% of a minimum-wage earner’s annual income depending on the number and combination of drugs being used. CONCLUSIONS: The price range of ocular hypotensive eye drops available in the Philippines is wide. Cost of therapy is an important consideration for patients who acquire medications through out-of-pocket expenditure. Optimization of bottle designs and volumes is crucial to maximize the cost-effectiveness of eye drop solutions. Information on the cost of therapy should be available to both patients and physicians.
