Efficacy of fitting HydroCone (Toris K) contact lenses for the visual rehabilitation of patients with posterior microphthalmos / Eficácia da adaptação de lentes de contato HydroCone (Toris K) para reabilitação visual de pacientes com microftalmia posterior

ABSTRACT Purpose: To evaluate the efficacy of soft HydroCone silicone hydrogel contact lenses in patients with posterior microphthalmos. Methods: The charts of 13 patients with posterior microphthalmos (26 eyes) who were fitted with soft HydroCone silicone hydrogel contact lenses were reviewed retrospectively. All the patients underwent assessments of uncorrected and best spectacle-corrected visual acuity and cycloplegic refraction. They were fitted with contact lenses according to the parameter values obtained from the topographical analysis and best contact lens-corrected visual acuity measurement. Results: The spherical equivalents of the right and left eyes ranged from 10.00 to 19.25 diopters and from 11.00 to 21.5 diopters, respectively. The mean axial and posterior chamber lengths were shorter than those of the age-matched population. However, the mean values of the anterior segment parameters such as horizontal visible iris diameter, central anterior chamber depth, lens thickness, and central corneal thickness were in the normal range. The mean keratometric measurements revealed increased corneal curvature compared with that in the normal population. The mean best contact lens-corrected visual acuity was significantly higher than the mean best spectacle-corrected visual acuity for both eyes (p=0.045). Conclusion: HydroCone silicon soft contact lenses provided better visual acuity than spectacles in the patients with posterior microphthalmos in this study.

RESUMO Objetivo: Avaliar a eficácia das lentes de contato gelatinosas HydroCone, de hidrogel com silicone, em pacientes com microftalmia posterior. Métodos: Foram revisados retrospectivamente 26 olhos com microftalmia posterior, a partir dos prontuários de 13 pacientes que receberam lentes de contato gelatinosas HydroCone, de hidrogel com silicone. Todos os pacientes foram submetidos ao exame de acuidade visual não corrigida e com melhor correção por óculos e com refração cicloplégica. Todos os pacientes receberam lentes de contato de acordo com os parâmetros obtidos na análise topográfica e foi obtida a melhor acuidade visual corrigida com lentes de contato. Resultados: O equivalente esférico do olho direito variou de 10,00 a 19,25 dioptrias, e o do olho esquerdo de 11,00 a 21,5 dioptrias. Os comprimentos médios axiais e das câmaras posteriores foram menores do que para a população de mesma idade. No entanto, os valores médios dos parâmetros do segmento anterior, como o diâmetro horizontal visível da íris, a profundidade da câmara anterior central, a espessura da lente e a espessura central da córnea estavam dentro da faixa normal. Os valores médios da ceratometria revelaram curvatura corneana aumentada em relação à população normal. A média da melhor acuidade visual corrigida com lentes de contato foi significativamente maior que a média da melhor acuidade visual corrigida com óculos em ambos os olhos (p=0,045). Conclusão: As lentes de contato gelatinosas de silicone HydroCone proporcionam melhor acuidade visual que óculos em pacientes com microftalmia posterior.

Analysis of ocular emergencies in a reference eye center in Brazil / Análise das emergências oculares em um centro de referência oftalmológica no Brasil

ABSTRACT Purpose: To determine the incidence of ocular emergencies and patient profiles in a public health eye center in Brazil. Methods: The medical record database of the Fundação Altino Ventura, Recife, Brazil was retrospectively analyzed and included all patients assisted at the ophthalmic emergency room between January 2017 and January 2018. Medical records with incomplete data and outpatient complaints were excluded. For records with multiple visits, only the initial visit was considered. Results: In 1 year, 134,788 patients (mean age at admission: 38.7 ± 22 years; range: 0-99 years) were admitted at the emergency room of the Fundação Altino Ventura. The most frequent diagnoses were conjunctivitis (52,732 cases; 37.3%), blepharitis (7,213 cases; 5.1%), and corneal/conjunctival foreign body (6,925 cases; 4.9%). Corneal/conjunctival foreign body and ocular trauma had an eight- and two-fold higher incidence in male patients, respectively (both p<0.001). Female patients presented a two-fold higher incidence of trichiasis and blepharitis than males (p<0.001). Corneal/conjunctival foreign body and ocular trauma affected more patients in a productive age (>15 years), while corneal ulcers, blepharitis, and trichiasis affected more elderly patients. All diagnostic clusters (e.g., infectious diseases, ocular trauma, foreign bodies, retinopathies, eyelid disorders, corneal diseases, glaucomatous crisis, and neuroophthalmological diseases) were more common during the spring season (p<0.001). Conclusion: The most common ocular emergencies in the present study were infectious diseases and foreign body. However, the incidence of ophthalmological emergencies was influenced by the age and sex of patients, as well as the time of the year.

RESUMO Objetivo: Determinar a incidência de emergências oculares em um centro oftalmológico de referência no Brasil. Métodos: O banco de dados de prontuários da Fundação Altino Ventura, Recife, Brasil, foi analisado retrospectivamente e incluiu pacientes atendidos, entre janeiro de 2017 e janeiro de 2018, na sala de emergência oftalmológica. Foram excluídos os prontuários com dados incompletos e com quadros ambulatoriais. Apenas o primeiro atendimento na emergência foi considerado para análise. Resultados: Em um ano, 134.788 pacientes (idade média de 38,7 ± 22 anos [0-99 anos]) foram admitidos na emergência da Fundação Altino Ventura. Os diagnósticos mais frequentes foram conjuntivite (52.732 casos [37,3%]), blefarite (7.213 casos [5,1%]) e corpo estranho na córnea/conjuntiva (6.925 casos [4,9%]). Corpo estranho na córnea/conjuntiva e trauma ocular foram cerca de 8 vezes e 2 vezes mais incidente em indivíduos do sexo masculino, respectivamente (p<0,001 em ambos). Triquíase e blefarite afetaram ~2 vezes mais pacientes do sexo feminino, respectivamente (p<0,001 em ambos). Corpo estranho na córnea/conjuntiva e trauma ocular afetaram mais pacientes em idade produtiva (>15 anos), enquanto úlcera, blefarite e triquíase da córnea afetaram mais pacientes idosos. Todos os grupamentos de diagnóstico (doenças infecciosas, trauma ocular, corpos estranhos, retinopatias, doenças das pálpebras, doenças da córnea, crise glaucomatosa e doenças neurooftalmológicas) foram mais incidentes na primavera (valor de p<0,001). Conclusão: As emergências oftalmológicas mais comuns no presente estudo foram as doenças infecciosas e o corpo estranho. Porém, a incidência das emergências oculares são fluências pela faixa etária e gênero do paciente, além da época do ano.

Unilateral papilledema and peripapillary polypoidal choroidal vasculopathy as the presenting manifestations of intracranial hypertension / Papiledema unilateral e vasculopatia polipoidal da coroide peripapilar como sinais de apresentação de hipertensão intracraniana

ABSTRACT We have reported here the case of a 54-year-old woman with intracranial hypertension that presented with the unique features of unilateral papilledema and peripapillary polypoidal choroidal vasculopathy. Our investigations lead to the diagnosis of idiopathic intracranial hypertension and an incidental small right frontal meningioma. The patient was accordingly treated with oral acetazolamide, followed by three consecutive monthly intravitreal injections of bevacizumab, which resulted in the inactivation of the polypoidal choroidal vasculopathy, marked reduction of lipid exudation, and complete absorption of the subretinal fluid. This case serves as the first documentation of polypoidal choroidal vasculopathy associated with papilledema. It also demonstrates that choroidal vascular abnormalities may occur even when optic disk edema is unilateral, which is an uncommon manifestation of increased intracranial pressure. Prompt recognition of such findings and its appropriate management are essential for adequate treatment and prevention of irreversible visual loss.

RESUMO Relatamos um caso de uma paciente de 54 anos com hipertensão intracraniana que apresentava achados atípicos de papiledema unilateral e vasculopatia polipoidal da coroide peripapilar. A investigação levou ao diagnóstico de hipertensão intracraniana idiopática e de um pequeno meningioma incidental. A paciente foi tratada com acetazolamida por via oral, seguida de três injeções intravítreas mensais de bevacizumabe, resultando em inatividade da vasculopatia polipoidal da coroide, redução da exsudação e completa absorção do líquido subretiniano. A apresentação deste caso serve para documentar pela primeira vez vasculopatia polipoidal da coroide associada a papiledema. Ele também demonstra que podem ocorrer anormalidades vasculares da coroide mesmo quando o edema do disco óptico é unilateral, uma manifestação incomum do aumento da pressão intracraniana. O reconhecimento imediato desses achados e seu manejo adequado são essenciais para o tratamento adequado e para prevenção da perda visual irreversível.

Two Cases of Uveo-meningeal Syndrome

PURPOSE: We report two cases of uveo-meningeal syndrome involving the retina, uvea, and optic disc in both eyes after viral meningitis. CASE SUMMARY: A 16-year-old female was referred to our department with blurred vision in both eyes. She was hospitalized in the pediatric ward with viral meningitis. She showed a norma best-corrected visual acuity (BCVA) and normal intraocular pressure in both eyes, but had severe inflammation in the anterior chamber on slit lamp examination, and optic disc edema and multiple whitish lesions on fundus examination. She was treated with intravenous antibiotic injections and steroid eye drops. After close observation, inflammation in the anterior chamber, optic disc edema, and the multiple whitish lesions in the retina were improved. A 27-year-old male who was treated for viral meningitis at the neurology department was referred to us with blurred vision in both eyes. His BCVAs were 0.7 (right eye) and 0.6 (left eye). The intraocular pressure was normal in both eyes. Slit lamp examination revealed inflammation in the anterior chamber and optic disc edema, and a fundus examination revealed multiple infiltrations. He received treatment for presumed herpes virus infection. After close observation, inflammation in the anterior chamber, optic disc edema, and multiple infiltrations with hemorrhage in the retina were improved. CONCLUSIONS: Clinicians should consider the possibility of uveo-meningeal syndrome, which can cause inflammation in the uvea,retina, and optic disc simultaneous with viral meningitis accompanying blurred vision.

With the special organization structure and function,retina is thought to be a prime candidate for developing the cellular therapies.Many types of stem cells have been explored to use for the treatment of retinal diseases and exhibit significant potential for further clinical application.However,before these results are translated to a clinical setting,sufficient investigations are required,such as the selection of the type of stem cells,transplantation strategy,the mechanism of therapeutic effect and biological safety,and how to get high differentiation efficiency,clarify the best development phase before transplantation,and achieve effective functional and structural integration of stem cells in the retina,etc.

Estimación del Perfil de Morbilidad en el Personal de la Aviación Civil en Colombia / Estimating the morbidity profile amongst Colombian civil aviation personnel

Objetivo Describir los principales procesos de morbilidad en tripulaciones y controladores aéreos pertenecientes a la aviación civil de Colombia. Métodos Estudio transversal descriptivo. Se tomó una muestra aleatoria de todos los registros clínicos existentes en el archivo de la dirección de Medicina de Aviación de la autoridad de la Aeronáutica Civil de Colombia que correspondió a 1 059 registros (de pilotos, auxiliares de servicios a bordo, controladores aéreos y operadores de estación aérea). Se revisaron las historias clínicas y se tomaron los datos de identificación, antecedentes, morbilidad y limitaciones actuales. Resultados De los 1 059 registros, 68,2 por ciento correspondieron a hombres, el promedio de edad fue 37 años. El 22,9 por ciento refirieron algún antecedente médico en la primera certificación. En el 17,1 por ciento se registró consumo de alcohol y en el 11,9 por ciento tabaquismo. Los principales diagnósticos encontrados fueron: los trastornos de la vision (52,2 por ciento), las dislipidemias (40,6 por ciento), aumento de peso (37,5 por ciento) principalmente sobrepeso (33,3 por ciento), la pérdida auditiva (22,0 por ciento), sano (14,0 por ciento) y HTA (8,1 por ciento). Los diagnósticos se conservaron en los diferentes grupos aunque en diferente orden. Conclusiones En otros estudios predominan las enfermedades cardiovasculares entre tripulantes y controladores aéreos. En Colombia los trastornos de la visión fueron los predominantes. No sabemos si hay una predisposición a padecer de estas enfermedades. En segundo lugar se encontraron factores de riesgo cardiovascular lo cual reviste vital importancia para la implementación de programas de promoción y prevención y para la salud publica.

Objective Describing main morbidity rate amongst Colombian civil aviation cockpit and air traffic control personnel. Methods This was a cross-sectional study. A random sample of 1,059 records (pilots, flight attendants, air traffic controllers) was taken from Colombian aeronautical authority files. Identification, background, morbidity and limitation data was reviewed for each one. Results 68,2 percent of the records concerned males. Average age was 37. 22,9 percent of the sample had some medical antecedent recorded on their first certification. Alcohol consumption (occasional) was recorded for 17,1 percent of the sample and 11,9 percent were smokers. The main diagnoses made were: vision disorders (52,2 percent), dyslipidemias (40,6 percent), being overweight (37,5 percent), having hearing loss (22,0 percent), being healthy (14,0 percent) and suffering from hypertension (8,1 percent). Each group had the same diagnoses, but occurring in a different order. Conclusions: Others studies have found cardiovascular disease to be the main cause of morbidity amongst cockpit and air traffic control personnel. Vision disorders were the main disorder occurring in Colombia. We do not know if there is a predisposition amongst Colombians to suffer such morbidity. Cardiovascular risk factors were found in second place in Colombia, meaning that public health prevention and promotion countermeasures should be taken.

A Case of Orbital Apex Syndrome Caused by Mucocele in the Sphenoid Sinus / 대한이비인후과학회지

Orbital complications of sinus disease continue to appear in clinical practice. Acute visual loss may occur in association with sinusitis either as a complication of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. The classification which defines the degree of orbital extension is valuable, therapeutically and prognostically. The orbital apex syndrome is associated with an affection of the vessels and nerves passing through the superior orbital fissure and the optic foramen and characterized by visual loss and ophthalmoplegia. But it has minimal or no signs of orbital inflammation such as proptosis, chemosis, or lid edema. We experienced a case of temporary monocular visual loss and ophthalmoplegia caused by mucocele in the sphenoid sinus. Thus, we report, with a review of literature, a case of orbital apex syndrome caused by mucocele in the sphenoid sinus in a 53 year-old male patient.
