Optical coherence tomography and multifocal electroretinography of patients with advanced neovascular age-related macular degeneration before, during, and after treatment with ranibizumab.

Purpose: To evaluate retinal morphology and function of patients with advanced neovascular age-related macular degeneration (AMD) before, during, and after treatment with ranibizumab.

Methods: Twenty-one eyes diagnosed with advanced AMD were studied with optical coherence tomography (OCT) and multifocal electroretinography (mfERG). Three intravitreal injections of ranibizumab were administered at 1-month intervals.

Human intraocular filariasis caused by Pelecitus sp. nematode, Brazil.

A male nematode was extracted from iris fibers of a man from the Brazilian Amazon region. This nematode belonged to the genus Pelecitus but was distinct from the 16 known species in this genus. Similarities with Pelecitus spp.

Dengue maculopathy: visual electrophysiology and optical coherence tomography.

The objective of this study was to evaluate the visual loss due to dengue fever using retinal and cortical electrophysiology and retinal imaging. The participants were three female patients with low visual acuity after dengue fever. They were evaluated by routine ophthalmological investigations, transient pattern electroretinogram (tPERG), transient pattern visual evoked cortical potential (tPVECP), and retinal optical coherence tomography (retinal OCT).

[Congenital retinal macrovessel: case report].

The authors report a case of arteriolar retinal macrovessel, diagnosed by routine ophthalmologic examination, as well as its optic coherence tomography aspects. Congenital retinal macrovessel is a large aberrant vessel, often unilateral, usually a vein, rarely an artery, located in the posterior pole which can cross the fovea and median raphe.

[Macular infarction after intravitreal injection of amikacin: case report].

The authors report a case of a patient who underwent cataract surgery with implantation of a posterior chamber intraocular lens and presented endophthalmitis on the second postoperative day. She was treated with intravitreal injection of amikacin, vancomycin and dexamethasone. After resolution of the infection the patient presented macular infarction and important loss of visual acuity due to amikacin toxicity.

[Frequency of ocular changes in patients with Hansen's disease living in a colony hospital].

Purpose: To identify the frequency of ocular changes in patients with Hansen's disease, living in a colony hospital; to confirm the predilection for the anterior segment of the eye instead of the posterior segment.

Methods: Transversal study of 115 eyes of 58 in-patients at João Paulo II colony, Marituba-Pará, from August to October 1999. The epidemiologic data of this research were obtained from the patients' charts and from information obtained at clinical eye examination.
