Este artigo apresenta um caso de infestação por carrapatos da pálpebra inferior por uma espécie previamente não declarada. Um homem de 71 anos de idade apresentou-se com um carrapato grudado na pálpebra inferior. O carrapato foi identificado morfologicamente, e, em seguida, uma estrutura molecular através de reacção em cadeia da polimerase (PCR) e a sequenciação do seu DNA. Além disso, uma análise da literatura pertinente aos gêneros de carrapatos associados à infestação do olho humano é fornecido. O carrapato, que […]

Acute rhinosinusitis is one of the most prevalent diseases of the upper airways. Anatomical factors present in children and young people allow for the onset of orbital complications. Although rare, intracranial complications of sinusitis account for a high degree of lethality, are more common in patients over the age of seven, and should be treated by a multidisciplinary team.

A female patient with juvenile glaucoma without clinical control underwent a trabeculectomy with mitomycin C, and developed eye hypotension which did not respond to conservative treatment, with subsequent hypotonic maculopathy. The patient was treated using a scleral patch provided by a donor above the fistula, which improved intraocular pressure and visual acuity. The use of the scleral patch above the fistula seems an adequate therapy to treat ocular hypotension due to the over-filtering trabeculectomy bubble. The surgeon should consider this […]

The authors present a case of choroidal osteoma diagnosed in a 25-year-old female patient. A well-defined and slightly elevated yellow lesion located in the posterior pole of the right eye was suspected to be a tumor. Confirmation of diagnosis was obtained with A and B ecography. The patient had low vision and macular edema, which improved after intraocular injection of bevacizumab .

Carotid-cavernous fistulas are a major cause of secondary glaucoma due to increased episcleral venous pressure. We present the case of a 72-year-old female patient, treated at the Hospital de Clínicas at the Universidade Federal do Triângulo Mineiro (HC-UFTM), with pain, proptosis, episcleral engorgement, chemosis and pulsation in the right eye, with increased intraocular pressure (IOP) on anti-glaucomatous medication.Arteriography showed dural fistula to the right cavernous sinus, with reflux to orbital veins.Treatment with liquid embolization agent was performed, following full recovery […]

This article presents a review of the principles and clinical applications of the Scheimpflug principle in the anterior segment imaging. By providing a three-dimensional image of the anterior segment, this technology provides elevation and curvature data of the anterior and posterior surfaces of the cornea, pachymetric mapping, the total refractive power of the cornea and the anterior segment biometry. For the refractive surgery sub-specialty, this approach improves the ability to identify cases at risk of ectasia, as well as the […]

Glaucoma is the leading cause of irreversible blindness worldwide and a major public health problem(1,2). Despite important advances in the diagnosis and management of glaucoma during the last decades, the fundamental understanding of intraocular pressure (IOP), its only modifiable risk factor, remains elusive. Whereas patients suffering from other chronic diseases, such as diabetes, have been empowered by the availability of round-the-clock monitoring devices, glaucoma patients have to make do with outdated technology available only in the physician’s office […].
