BACKGROUND Several authors reported incorrect high intraocular pressure (IOP) values in eyes with a thick cornea using applanation tonometry. This hypothesis was checked by comparing applanation tonometry with direct intracameral manometry. METHODS 73 patients, scheduled for intraocular surgery, were enrolled. Immediately before surgery, the following were registered: (i) central corneal thic...

UNLABELLED The purpose of this study was to measure the changes in intraocular pressure (IOP) and refraction following orbital decompression for thyroid orbitopathy. METHODS Retrospective review of 18 eyes in 10 consecutive patients who underwent orbital decompression including intraconal fat excision for proptosis secondary to thyroid orbitopathy. IOP using tonopen, exophthalmometry, autoref...

OBJECTIVE To assess 24-hour intraocular pressure (IOP) and ocular perfusion pressure rhythms in newly diagnosed apneic patients before and after nasal continuous positive airway pressure (nCPAP) treatment. METHODS Intraocular pressure (using a Tonopen XL) and ambulatory blood pressure, measured hourly for 24 hours, were analyzed in 18 consecutive patients with obstructive sleep apnea for nyct...

BACKGROUND Metallic corneal foreign bodies (MCFB) are one of the most common causes of ocular injury presenting to the emergency department.1-4 Patients are at risk of developing tissue necrosis, infection, and even vision loss if the foreign body is not removed in a timely manner.1-3,5,6 Traditionally, these foreign bodies are removed under slit-lamp examination using a sterile, large-gauge ne...

Objetivo: Avaliar a pressão intraocular e a pressão de perfusão ocular durante uma sessão de hemodiálise. Métodos: Sessenta e sete olhos de trinta e cinco pacientes foram avaliados no início, após 2 horas e após 4 horas do início de uma sessão de hemodiálise. A pressão intraocular foi avaliada usando o aparelho Tonopen. Pressões arteriais sistólica e diastólica foram aferidas usando esfigmomanô...
