Toxoplasmosis is a zoonosis whose etiologic agent is Toxoplasma gondii, which is characterized as an infectious disease of worldwide distribution. There are thought to be more than 2 billion people globally infected with toxoplasmosis. It is well known that toxoplasmosis is a frequent cause of chorioretinal scarring. In this group of diseases, the angiographic examination (or retinal fluorescein angiography) is very important for diagnosis. Objective: To perform a survey on the prevalence of chorioretinal scars in angiography at a private […]

Visceral Leishmaniasis, also know as Kala-azar, is a parasitic tropical disease caused by protozoa of the genus Leishmania donovani. It is an endemic disease in many countries. It affects approximately 1,5 million people every year, and when associated with mal-nutrition and co-infection it may be fatal. Fever, hepatosplenomegaly, and pancytopenia is its typical clinical picture. Ocular manifestations of Kalaazar are relatively rare and can affect either anterior or posterior segment of the eye. We report a patient with kala-azar presenting […]

Vitrectomy is a surgery that involves complex and delicate techniques that treat diseases such as macular hole, epiretinal membrane and diabetic macular edema. Chromovitrectomy is one of these techniques and includes the use of coloring agents such as vital dyes or crystals to enhanced visibility of transparent structures during vitrectomy. The aim of this study was to present a modern approach, based on scientific evidence, about the application and indication of vital coloring agents during vitrectomy. The use of such […]

A cirurgia vitreorretiniana é uma cirurgia que envolve técnicas complexas e delicadas que tratam doenças como buraco macular, membrana epirretiniana e o edema macular diabético. A cromovitrectomia é uma dessas técnicas que incluem o uso de corantes compostos de pigmentos vitais ou cristais para melhorar a visibilização de estruturas transparentes durante a cirurgia de vitrectomia. O objetivo desse artigo foi apresentar uma abordagem atual, baseada em evidências, sobre a aplicação e indicação de corantes vitais durante a cirurgia vitreorretiniana. O […]

Choroidal folds is considered the most prevalent funduscopic finding in cases of orbital tumors. They are ripples in the retinal pigment epithelium, Bruch’s membrane, the inner portion of the choriocapillaris and in some cases, may affect the neurosensory retina, and then called chorioretinal folds. Several ocular and systemic conditions are associated with the finding and must be properly investigated and, if necessary, promptly treated. In this review we discuss the general aspects of choroidal folds, emphasizing their characteristic features in […]

Report of a 48 year-old male with bilateral decrease in vision due to choroidal neovascularization secondary to angioid streaks.
