Study conducted to report a case of Cogan Reese syndrome. Female patient, 55 years old with diagnosis of Cogan Reese syndrome. Best visual acuity of 0.67 in the right eye and 0.2 in the left eye. By biomicroscopic examination there was no abnormalities in the right eye. In the left eye there were pigmented nodules on the anterior surface of the iris, corneal irregularities and iris hole (pseudopolycoria). The intraocular pressure was 18 mmHg in the left eye and there […]

O glaucoma compreende um grupo de neuropatias ópticas progressivas que tem em comum a degeneração lenta e progressiva das células ganglionares e seus axônios, resultando em aparência única do disco óptico e, simultaneamente, um padrão correspondente de perda visual. Biomarcadores são características medidas objetivamente e avaliadas como indicadores de processo biológico normal, processos patológicos ou respostas farmacológicas à uma intervenção terapêutica. Vários marcadores biológicos foram associados com glaucoma, especialmente os genéticos, proteômicos, autoimunes e outros biomarcadores moleculares, embora a maioria […]

Objective The purpose of this study was to perform an objective videotaped evaluation of the difficulties of eyedrop instillation and daily tasks in patients with advanced glaucoma with visual impairment Methods A prospective observational study was performed in advanced glaucoma patients with visual impairment, during 5 months. Patients completed a survey (with demographic questions, quality of life, compliance and eyedrop instillation) with interview and video recording in specific daily tasks (eyedrop instillation, climbing stairs, walking in a crowded room and […]

Sturge-Weber Syndrome is a rare neuro-oculocutaneous disorder. The authors describe the case of a 13 years old boy, presented with bilateral Sturge-Weber Syndrome and glaucoma. Surgical treatment with Ahmed valve implantation in both eyes was carried out achieving lower levels of intraocular pressure.

A síndrome de Sturge-Weber trata-se de uma doença neuro-óculocutânea rara. Os autores relatam o caso de um paciente do sexo masculino, de 13 anos de idade, que se apresentou com Síndrome de Sturge-Weber bilateral e glaucoma. Foi realizado o tratamento cirúrgico com implante de válvula de Ahmed em ambos os olhos e alcançado a redução da pressão intraocular bilateral.

Objective: Demonstrate the Brimonidine effect over Retinal Spreading Depression (SD). Brimonidine is an alpha-2–adrenergic receptor agonist, used in the management of glaucoma. Alpha2-agonists have been shown to be neuroprotective in various experimental models, however the molecular and cellular targets leading to these actions are still poorly defined. The SD of neuronal electric activity is a wave of cellular massive sustained depolarization that damages the nervous tissue. Local trauma, pressure, ischemic injuries and other chemical agents as high extracellular potassium concentration […]

Objetivo: Demonstrar o efeito do Tartarato de Brimonidina, um alfa2-agonista usado no manejo do glaucoma, sobre a depressão alastrante (DA) retiniana. Esses agonistas têm demonstrado ser neuroprotetores em vários modelos experimentais, contudo seus alvos celulares e moleculares continuam indefinidos. A DA da atividade elétrica neuronal é uma onda de despolarização celular massiva e sustentada que leva ao dano no tecido nervoso. Trauma local, pressão, isquemia e outros agentes químicos como o aumento do potássio extracelular e o glutamato podem disparar […]

The pituitary adenoma is a tumor of slow evolution and has important visual disturbances such as low visual acuity and field defects. These symptoms lead patients to seek often ophthalmologists. In this case, we will analyze a patient with glaucoma who had an associated pituitary macroadenoma.
